Strategy Pattern Creation in Forest Planning in Swedish Forest-Owning Companies

Forest-owning companies in Sweden have both a goal to yield a good short-term rate of return on their forest and a goal to maintain a high long-term rate of return by maintaining the production of wood-based products. Both these objectives are taken into account in the forest planning process. For the long-term goal, the companies develop strategies formulated in the forest planning system and for the short-term goal, sale strategies are formulated in the sale plans. These strategies may raise conflicts on how to use the forest resources. These conflicts would occur in the work with the tract bank (TB), the register of stands ready for harvesting. The objective of this study was to analyze how Swedish forest owning companies form their strategy patterns around the work with the TB and to discuss the implications of the pattern formation for forest planning in the companies. Planners and harvest managers at three large forest-owning companies responded to a questionnaire. The results show that the delivery plan based on the sale strategy is often a main factor in determining the content of the TB.


Introduction
Swedish forest owning companies have two main objectives: (a) to obtain a good short-term rate of return on their forests; and (b) to maintain a high long-term rate of return by managing the forests sustainably to maintain their output of wood-based products.Both of these objectives must be OPEN ACCESS considered when drawing up the long-term forest plan and determining the forest's harvesting potential over the coming 10 years.In the medium-term forest plan, the forest planners select and prepare the compartments to be harvested.Their work focuses primarily on maintaining the forest's long-term production and promoting its sustainable use.The work of harvesting managers is based around the short-term forest plan and focuses on delivery plans that are made according to the company's sales of its wood-based products.The forest's long-term development is dependent on the forest planning system, whereas the implementation of the short-term strategies is formulated in the company's sales plan and delivery schedule.The need to simultaneously meet the short-and long-term objectives can create conflicts regarding the use of forest resources.When strategies are implemented, diversions from their original plans might occur as conditions have changed.As such a strategy pattern is formed.The two planning hierarchies, forest planning and sales planning, meet in the tract bank (TB) the register of stands ready for harvesting.The objective of this study was to analyze how Swedish forest owning companies form their strategy patterns around the work with the TB and to discuss the implications of the pattern formation for forest planning in the companies.

Theoretical Background
All large forest owning companies in Sweden adopt similar approaches when planning their forestry activities [1,2].They use a hierarchical planning system that is based on a long-term plan (also known as the harvest estimation or strategic plan), a medium-term plan (or tactical plan) and a short-term plan (or operative plan), as shown in Figure 1 [3,4].This planning hierarchy was introduced by the industrial forest companies in the 1960s and remains in use today [5,6].The conceptual planning system is seen as a consecutive sequence of decisions in which the range of available options at any one stage is defined by the choices made in the preceding stages.The actual harvesting operations and deliveries to mills are therefore assumed to be controlled by the forest planning hierarchy, so in theory the potential short-term rate of return is dependent on the long-term rate of return.The forest's harvesting potential is estimated when drawing up the long-term plan.These estimates are made to maximize the company's profits and are normally revised on a five-or ten-yearly basis; they are typically drawn up to cover a period of approximately 100 years [7].Long-term plans are created to enforce sustainability in a way that is economically optimal in both the short term and the long term.The optimized long-term plan is used as the base for the next level of the forest planning hierarchy, the medium-term plan.Medium-term plans cover periods of three to ten years and are made on regional and local scales; they specify which compartments within the covered area are to be harvested or thinned.The cost of harvesting is an important factor when selecting compartments for these purposes [8,9].The medium-term plan is linked to a number of other plans, such as road construction plans, fertilizing plans and sales plans.The medium term plan ends with a database, the TB, in which compartments available for harvest are listed.The short term forest plan covers a period of one to three months and provides a schedule of compartments for harvesting that is created to satisfy the demands of customers and mills as specified in the delivery plan.Short-term plans are made exclusively at the local level.Delivery plans can change at short notice, for example because of a temporary halt in production at a mill or problems with other deliveries.Inputs considered when creating short-term forest plans are the compartments listed in the TB and the available harvesting resources.The purpose of short-term plans is to ensure that mills and customers receive a steady supply of material according to the delivery plan by designating appropriate volumes of each assortment for harvesting.In addition to making efficient use of the available harvesting resources and satisfying the material demands specified in the delivery plan, the short-term plan must account for the cost of harvesting, the prevailing weather conditions, and the ground conditions at the chosen sites.The outputs of the short-term plan are timber logs and pulp wood for delivery to the mills.
In this description, the TB is part of the medium-term plan.However, it can also be regarded as the plan's output.When a compartment is chosen for harvesting, a planner visits the site, delineates it, measures the trees, and makes sure that it can be accessed by road.In some cases, this can be done by analyzing remote imaging data together with information from the stand register.Once this has been done, the compartment is moved into the TB.These actions are referred to as "planning" the harvesting site or compartment.The compartments in the TB then become available to the harvest manager and can be designated for harvesting in short-term forest plans.
Since the forest planning hierarchy is based on a chain of plans and all decisions made within the hierarchy are influenced by those made at preceding stages, the selection of any one compartment for harvesting can be seen as a consequence of the choices made at earlier stages in the planning sequence.The TB consists of compartments with a combined harvesting volume of approximately 1.5-2 years [10].The mix of compartments in the TB should broadly reflect the mix in the medium-term plan in order to ensure that a steady output of different wood products can be maintained from season to season and from year to year.
The most important buyers of wood-based products are sawmills, pulp and paper mills, and district heating plants.Sales are planned using a two-stage hierarchical system.At the company level, a business plan is drawn up with a time horizon of three to five years [10].This plan encompasses plans for customer relations and the company's sales strategies.It is used to establish short term sales plans, which cover a period of one year at the local level.The short term sales plans allocate defined volumes of each assortment to specific customers within the region.They serve as the basis of negotiations with the buyers; once contracts have been signed with customers, they are replaced by delivery plans.Delivery plans are dynamic, and can be adjusted to follow the market and adapt to changes in customers' demands.
Mintzberg and Waters [11] point out that strategies are not just the plans that are made and implemented by the leadership of an organization; strategies can also be regarded as the pattern of decisions made and actions taken by the organization.That is to say, strategies can be understood in terms of either forward-looking plans or historical patterns.An organization's intended strategy or plan can be compared to the actions it actually takes, i.e., the realized strategy.In most cases, some aspects of the intended strategy will not be realized due to changes in conditions or because of flaws in the assumptions made when it was established.These changes in environment can be both external and internal in terms of loss of capabilities or groups or persons with goals divergent from the management.New strategies emerge in response to the same changes, and the resulting actions will become part of the realized strategy (Figure 2).In forest planning, the result of the long-term plan can be seen as the intended strategies.The realized strategy will then be the pattern made by the harvest actions, when the stands are harvested.
In their study, Mintzberg and Waters [11] described eight different realized strategies, including the planned strategy and the umbrella strategy.A planned strategy is one in which the company's management plans its actions very precisely and then implements the strategy without considering input from the company's operating environment or from within the organization.In a perfect planned strategy, subsequent events unfold exactly as intended.Under the framework outlined in Figure 2, a planned strategy is an extreme example of a deliberate strategy.Strategies of this sort are only viable for organizations that operate exclusively in predictable environments.Conversely, the management of an organization that uses an umbrella strategy sets out to create an operating framework that is built around a vision.This defines a set of boundaries within which other actors in the organization are relatively free to operate.To ensure that their strategy is followed, the leaders must also have a plan for its implementation.Strategies of this type are both deliberate and emergent.Rather than specifying exactly what actions should be taken by their subordinates, the company's management outlines a vision and specifies boundaries within which a strategy can emerge and evolve.In such cases, it is important to have a way of monitoring the actions taken by the company's employees.If an actor starts operating outside the specified boundaries, the management has three choices: they can call a halt to the employee's activities, ignore them, or adapt to them.Umbrella strategies are commonly used by organizations that operate in unpredictable or rapidly-changing environments because they give the organization and individual employees a lot of flexibility when responding to such situations.The various units of the organization work to implement strategies according to the instructions they receive from the organization's management and by doing so, they create a strategy pattern.Because these different units work under different conditions, they will probably create different patterns even if they generally are working towards a common goal.Cyert and Marsh [12] noted that:"… we cannot dispose of bias problems by assuming goal homogeneity.Where different parts of the organization have responsibility for different pieces of information relevant to a decision, we would expect some bias in information transmitted due to perceptual differences among the subunits and some attempts to manipulate information as a device for manipulating the decision".In order to ensure that knowledge is used appropriately and effectively throughout the organization, it must be carefully managed.If the overall organizational strategy requires cooperation between units, the organization's knowledge must be shared in a way that makes it accessible to all units.Porter [13] expressed this requirement as follows: "With separation of organizational units comes the need to coordinate them, usually termed 'integration'.Thus integrating mechanisms must be established in a firm to ensure that the required coordination takes place.Organizational structure balances the benefits of separation and integration".

Materials and Methods
Three large Swedish forest owning companies, all of which use an internal planning hierarchy, participated in this study (Holmen, SCA and Sveaskog).Email messages were sent to one person in each company, inviting them to participate.These initial contacts graciously gave the authors the e-mail addresses of a selected group of respondents at each company.The members of these groups included forest planning managers (who are responsible for forest planning at the regional level and/or selecting compartments for the medium-term forest plan), forest planners (who are responsible for measuring and delineating compartments and may also decide which compartments will be included in subsequent planning processes), and harvest managers (who are responsible for scheduling harvesting operations, i.e., creating short-term forest plans).The contact person also sent e-mails to the respondents in each company requesting that they participate in the survey.
In total, 318 individuals from the three companies were contacted by e-mail and given personal links to a web-based questionnaire that was set up using the Netigate survey tool.The respondents' answers were anonymised; no personal information on the respondents was collected, so it was not possible to trace an individual's responses back to a specific company or region.This was judged as necessary to avoid non-answer as some of the questions being asked might be regarded by the respondents as touching upon internal business policies not to be revealed to outsiders.However, the design of the questionnaire made it possible to distinguish between the responses of forest planners (including forest planning managers) and harvesting managers.The respondents were given four days in September 2012 to complete the survey (Tuesday-Friday).After two days, a reminder email was automatically sent to individuals who had not completed the survey at that point (The survey tool was able to identify respondents who had not yet answered the survey).At the end of the four days, 159 responses had been received, giving a response rate of 50%.Of the respondents, 62% were forest planners and 35% were harvest managers.Six respondents (4%) were neither forest planners nor harvest managers, and their responses were excluded from the analysis.Nine e-mail responses were received from people who were away from work when the survey was conducted.Each company was asked to provide complete e-mail lists, i.e., lists that contained the email addresses of every one of their employees in the relevant positions.Unfortunately, the lists that were received included the addresses of some employees who worked in other positions.We were unable to determine what proportion of the non-respondents fell into this category.It is also possible that some individuals who work as forest planners/harvest managers were omitted from the lists.The emails that provided the link to the survey stated its purpose clearly and were written with the aim of clearly stating who the desired respondents were and encouraging their participation.It is possible that this may have decreased the rate of response from people who do not work as forest managers or harvest managers but were mistakenly contacted.These factors make it difficult to make any statements about the non-respondents with confidence.
The first questions of the survey were designed to determine whether the respondent's duties were most like those of a harvest manager or a forest planner.Depending on their answers, the respondent was then directed to questions appropriate for their apparent occupation.Both sets of questions had three sections: one on the short-term forest plan, one on the medium-term forest plan, and one on the TB.The survey included open-ended questions, close-ended questions, and ranking questions.Open-ended questions were used when we wanted to obtain a fundamental understanding of the respondents' opinion and to avoid bias by giving specific answer opportunities.The majority of questions were however closed-ended questions with specific options to choose between and ranking questions.Both type of questions invited the respondents to comment.To avoid confusion when asking about opinions, all ranking questions consisted of statements to which the respondent could choose one of four responses, ranging from "do not agree at all" to "totally agree".An even-numbered scale was chosen to avoid neutral answers.Most of the questions were formulated in such a way that the answers were comparable between the two groups.Before sending the survey to the actual respondents, the survey was tested by sending it to several recently retired harvest managers and forest planners to check on the content, wording, alternatives provided in the close-ended questions and comprehension of the scale used.Very few participants did not answer the complete list of questions.When calculating the relative response rate for the options the number of answers for each question was used.
Our analysis focused on four major issues: the selection of compartments that enter and exit the TB, the size and composition of the TB, the information within the TB, and the communication within the organization during work relating to the TB.The answers to open-ended questions were grouped according to overarching themes and specific interesting responses are quoted in their entirety and presented to illustrate more general points.
In connection to harvesting, both production and delivery plans are common terms used by harvest managers and planners.In this study it was seen not relevant to distinguish between these plans and for consistency in terminology these plans are both referred to as delivery plans in this paper.However, as the terms are used in the companies, both words have been used in the questionnaire and they both appear in Table 1 as separate results.
Table 1.The most important factors to consider when making short-term forest plans as identified by harvest managers, and the factors that planners believe forest managers should consider to be most important when making short-term plans.In this table, delivery plan and production plan are presented separately as they were separated in the questionnaire.

General Introduction
The harvest managers were asked to specify which factors they considered to be most important in the creation of short-term forest plans.The planners were asked to specify which factors they thought should be given the greatest weight by harvest managers when making short-term forest plans (Table 1).In this case, the respondents were asked to choose from a range of fixed options, one of which was "other".
Both groups considered the delivery plan to be the most important factor.The planners considered the TB to be the second most important factor, whereas the harvest managers considered it to be only the fifth most important factor.
One harvest manager added the following comment: "the tree species distribution and the average stem diameter in the compartment are the most important factors to consider when trying to provide timber that will satisfy the mills' demands.After that, one must consider the condition of the roads and the ground at each site in order to estimate when we will be able to deliver the timber to the mills".A planner added: "In order to get good results in the forest, it is important to ensure that the right machinery and people are available at the right time, to keep track of ditches, and to use harvesting volumes that are realistic in relation to growth and timber sales".
Harvest managers and planners identified software and GIS programs as the typical way to store TBs.Approximately two third of the harvest managers said the TB was stored in a specific software and one third that it was stored in the software used for most things.The planners gave the opposite relation between these two software versions, approximately one third said a specific software and two third the GIS-software used for most things.This seems not to be totally adapted by all organizations since one harvest manager wrote: "It is stored in the GIS software.However, because the software does not fully support out workflow, we also store the data in binders".

The Size and Composition of the TB
The groups were asked about their perceptions of the size of the TB and how big they would like the TB to be.Table 2 shows that a considerable share of the harvest managers and planners do not concept the size of the TB in the same way.Figure 3 shows the preferred size of the TB compared to the size it is currently believed to have for both groups.It is clear that a majority of both groups would like to have a larger TB.The open questions allowed both groups to provide further insights into their perception of the TB's size and composition.Some of their responses are presented in full below.The size of the TB is often given as a measure for how usable it is.The size is often given in units of "years" which is short for "the total volume to be harvested during a year" or the "annual cut volume".Both harvest managers and planners had comments about the size of the TB.Some of the planners expressed opinions such as: "[The ideal TB size] really depends on the geography and ground conditions within the TB.Areas with better ground conditions could get by with a smaller TB".Another planner stated that the size of the TB affected the quality of the work that could be achieved: "It is easier to maintain a high quality of operative planning when the TB is sufficiently large" (Operative planning here, is the work done by planners to prepare a compartment for admission into the TB).One planner was unsure of the TB's true size: "I am not sure how big it really is".One harvest manager expressed concerns about the size of the TB: "Of course, the TB plays a central role because it is effectively our stock.Obviously, it is not optimal from an overall perspective to have a TB that is too large".The respondents also made comments about the composition of the TB in terms of the volume that is actually available for use, not just the size of the TB.One planner said: "How is it the case that the TB has a size of 2 years if there are compartments that have to be replanned many times because the notification of regeneration felling'expires' both once and twice?They are not being harvested".(Notification of regeneration felling concerns the permission to perform a regeneration harvesting operation given by the Swedish Forest Agency.It is usually valid for three years).Another planner wrote: "The contents of the TB must be harmonized with the notifications of regeneration felling.If the TB becomes too large, there is a risk that compartments may be harvested after the notification period has expired (3 years)" and "there is no point in planning for small satellite compartments; they don't get harvested".A harvest manager expressed similar opinions: "If you have a larger TB, more compartments will be left unharvested in the TB.Purchased volumes are prioritized.Some compartments are more or less never right for harvesting".
Some respondents commented on the mixture of different compartments in the TB and their relative quality.The importance of some qualities differs during the year.Some planners expressed strong opinions about the balance of the TB "It is not just the quantity (i.e., the area) of the TB that matters: the quality is more important.You have to have a well balanced bank with compartments that are useful for all seasons and ground conditions" and "It does not need to be very large as long as it has the required qualities".Another planner said that "size alone does not necessarily mean that it is possible to harvest".Several harvest managers agreed with these planners: "The TB may provide 3 annual cuts, but what is important is how much you have per season" and "We often have imbalances between the number of compartments within the TB that have acceptable ground conditions and passable roads in each season.In the spring, and also in the fall when it's wet, there aren't many compartments that can be harvested, which reduces the scope for planning" and "I have a lot of compartments for the winter and summer, but there is often a lack of harvestable compartments during the spring and fall.I don't often have problems with the company forests, but there are occasionally troubles with purchased compartments.It can be very hard to find suitable assortments in some cases (e.g.spruce during springtime)".At least one of the participating organizations uses separate TBs for thinning and final felling, and for their own forests and purchased volumes.These different TBs can differ in the balance and composition of their compartments.One harvest manager noted that "the size of the TB is different for thinning and final felling" and "We have a very low stock of final felling compartments but have far more thinning compartments-approximately two years' worth".
The respondents were given the opportunity to provide open-ended comments about the TB. 10 harvest managers and 13 planners did so.Their answers were grouped into six categories based on the factors they mentioned; some were placed in more than one category (Figure 4).The results show that the view of the TB can differ between the two groups.In general, the harvest managers focused on issues with the compartments within the TB, and the planners primarily focused on which compartments that are in the TB.The planners also mentioned that compartments can remain in the TB for a very long time without being harvested.

The Information within the TB
Both groups were asked about their tolerance of errors in information relating to three different factors: (i) the volume to be harvested within a compartment; (ii) the mix of tree species within a compartment and (iii) the ground conditions within the compartment.The acceptability of each error type was measured by asking the respondent to what extent they agreed to the following statements: (A) a deviation of 10%-20% in the volume of a planned compartment does not matter much, there are also many other affecting factors (volume); (B) a deviation of 10%-20% in the species mix of a planned compartment does not matter much, there are also many other affecting factors (species mix); (C) it is not very important of the ground conditions within a compartment are not specified correctly in the TB (ground conditions).When the responders were answering the survey, all three of these questions were shown on the screen at the same time.The possible answers were assigned the following weightings: "not at all"-1, "to some extent"-2, etc.The mean weighting for each error type was then computed, giving the results shown in Figure 5.The planners were more accepting of errors in all three variables than the harvest managers.The groups assigned the same order for the three factors.Neither group considered any of the listed variables to be unimportant.
The harvesting managers rated the statement "It is common for the TB to contain inaccurate information about the volume or distribution of assortments within compartments" as follows: not at all, 21% (10), to some extent, 42% (20), quite a lot, 21% (10), totally, 17% (8), n/a, 0% (0).The planners were asked to rate the statement: "I do not want to put compartments into the TB if the information on their volume or assortment distribution is inaccurate".Their ratings of this statement were as follows: not at all, 7% (6), to some extent, 16% (14), quite a lot, 22% (19), totally, 47% (40), n/a, 7% (6). Figure 6 shows the harvest managers' ratings of the trustworthiness of the data in the TB on the availability of passable roads in each compartment.The figure shows that some of the harvest managers were not sure that all compartments in the TB are ready for harvesting.One of their concerns Harvest managers (10) Planners (13) was about the availability of roads and turning space for trucks.One harvest manager wrote: "The TB contains too many compartments that are not ready for harvesting or are only accessible via roads that are not useful and so on".Another doubt about the quality of the data in the TB was raised by the harvest managers' ratings of the statement "there are many compartments in the TB, but not all of them are ready to be harvested".24% did not agree with this statement at all, 55% agreed to some extent, 14% agreed quite a lot and 4% agreed totally (2% n/a).The planners were asked to state the extent of their agreement to the statement "there are many compartments in the TB, but the harvest managers do not want to harvest expensive/difficult compartments".19% did not agree at all, 47% agreed to some extent, 22% agreed quite a lot, and 11% agreed totally (1% n/a).

The Communication within the Organization during Work Related to the TB
Both groups were asked how much contact they have with members of the other group regarding the contents of the TB.In both groups, more than half of the respondents said that they maintain contact with the other group to ensure that appropriate compartments are allocated to the TB (Table 3).Many of the harvest managers (79%) said that they discuss matters with planners to ensure that appropriate compartments are put into the TB.A majority (73%) of the planners said that they decide which compartments will go into the TB; of this group, almost two thirds (62%) said that they hold discussions with harvest managers to determine which compartments should be planned (i.e., put into the TB).

Harvest managers (47) 79% (37) 15% ( 7) 6% (3) Planners in charge of putting compartments into the tract bank.(64) ( = 73% of all planners) 62% (40) 28% ( 18) 9% ( 6) With reference to this subject, one planner stated that "the harvest manager knows a lot about the area and can provide useful information when drawing up the TB".On the other hand, one harvest manager wrote that "the TB is filled without any influence from the harvesting group; we just make use of it".
The harvest managers and planners both agreed with the statement that "the selection of compartments for the TB depends on the forest plans, not the delivery plan", as shown in Figure 7.However, the planners placed more emphasis on the importance of the forest plans than the harvest managers.These results show that even though the harvest managers primarily work on the short-term forest plan and their goals relate to meeting delivery quotas, they are involved in the selection of compartments for the TB.

The Selection of Compartments that Enter or Exit the TB
The harvest managers were asked whether they ever select compartments for the short-term forest plan that are not in the TB.The specific statement they were asked to assess was "sometimes I have to schedule compartments in the short-term forest plan that are not in the TB"; 39% (19) of the managers did not agree with this at all, 35% (17) agreed to some extent, 8% (4) agreed quite a lot, 8% (4) agreed totally, and 10% (5) did not respond or said the statement was inapplicable to their work.
The TB is the last stage of the medium-term plan.In the planning system, the medium-term plan is supposed to be the source of the compartments that go into the TB.In order to provide a satisfactory foundation for the establishment of the TB, the medium-term plan must satisfy some essential criteria.One of the planners' main desires was that the medium-term plan should be presented in a straightforward way, preferably via GIS.When asked about how he/she would like the TB to be laid out, one planner stated that "it should be as exact as possible and should take road systems, ground conditions, tree species and assortments into account.Its details should be checked and updated after the planning seasons and it should be easily viewed in a GIS software package".Another wrote that "it should be easy to visualize the TB geographically and to see the selected volumes in the GIS software package.It should also be better connected to the national road database".Some organizations seem to have a method for storing the medium-term plan that is well suited to the planners' workflow; one wrote that he/she was content with the employer's current system in which "compartments that have been selected and prioritized are identified in the GIS-software along with their designated year for harvesting".One planner stated that compartments are sometimes admitted into the TB without having been accounted for in the medium-term plan: "Extra volumes that are taken are never compensated for in other years.These days it is difficult to maintain coordination between purchased volumes and volumes sourced from our own forests because the relative sizes of these volumes are more important than their coordination".
The planners also wanted the medium-term plan to be balanced in the sense that it should contain compartments with different attributes in the same way that the TB should be balanced so as to mirror the composition of the forests.One planner noted that ideally, the TB would contain "a geographically even and concentrated selection of assortments with an even distribution between thinning and final felling".Another planner highlighted the importance of the forest planning hierarchy: "The plan must be designed to allow for long-term sustainable forest management in a way that accounts for environmental values, economic factors, and the company's strategy".
The planners were also interested in the information within the medium term plan because they use it in their work on the TB.Some of the planners commented on this subject: "The medium-term plan provides helpful support in the planning work [inventory, etc].It should contain information on the approximate volume in each compartment, as well as data on road and ground conditions and an order of priority".Another said that "the stand information is more reliable when there is time to go out and visit the sites.This is especially true for the site index; if we are dealing with a spring compartment, it should not be visited during the winter.Unfortunately, this is not always the case at present; a lot of time is wasted because of relocations".A third planner highlighted a range of factors that should be included in the medium-term plan: "The priority assigned to different compartments.The accessibility of the compartments for both winter and summer harvests.The contents of the compartments.Longer time horizons of accessible compartments after consultations with different stakeholders".One planner provided an alternative perspective on working with medium-term forest plans: "There is nothing wrong with the plans.Unfortunately, however, the demand from the mills does not always match up with the composition of the forest".
Some comments revealed a lack of faith in the harvest estimates contained in the long-term forest plans, and thus in the output of the subsequent elements of the planning system: "We start from the long term harvest estimates for both final felling and thinning.I think that these are too optimistic for the long term cuttings".Another noted that "it does not matter what your plan looks like if it is changing all the time, and the main reason for making it in the first place didn't have anything to do with how the forest growths and looks.That is, plans are often made based on how somebody wants the forest to look in order to meet some financial goal or timber production objective rather than reality".A third said that "it is hard to fill out the medium-term plan because there are too few available compartments compared to the long-term estimates," and "planning small compartments is pointless-they don't get harvested".One harvest manager also identified a problem in the way plans are drawn up: "the problem has been that we plan to reach our own goals.The quality decreases when the goals are so high that we have to take short cuts to reach them".

Discussion
This study revealed that, although planners have a good understanding for the work of the harvest managers and vice versa, the planners' view on work with the TB is based on the hierarchical forest planning system as depicted in Figure 1 and that the harvest managers' view is based on the sales strategy.It appears also that the sales strategy dominates the work with the TB, a majority of the planners and harvest managers maintain contact to ensure that the content of the TB matches delivery plans and a majority of harvest managers state that they have scheduled compartments that were not in the TB.This diversion of the intended forest planning strategy may in itself be justified, but should be regulated by the company's management.The study also showed that the companies' employees have doubts about the correctness of data and that these doubts may influence their way of working with the TB.This may affect the strategy pattern that unfolds and therefore the companies' performances.
Our analysis focused on four basic issues: the size and composition of the TB, the information within the TB, the communication within the organization during work relating to the TB and finally the selection of compartments that enter and exit the TB.These issues were chosen because they show how the company's knowledge of the forest is managed during the realization of its long-and short-term strategies.
The harvest managers and planners perceived the TB in different ways.Together with the selected quotations, the results shown in Table 2 describe a situation in which the harvest managers and planners have different understandings of the size and composition of the TB.The TB contains compartments that the harvest managers consider to be unmanageable and which effectively reduce its size from their perspective.Such compartments are not taken into account by the harvest managers, which may be why 76% of the harvest managers want the TB to be larger than it is at present.In addition, the harvest managers use the TB to draw up schedules for their employees and entrepreneurs, and also need to be able to quickly respond to changes in customer demand.These factors may influence their desire for a larger TB that would provide a broader range of options for scheduling.According to Figure 3, 60% of the planners also want a larger TB.However, their responses also indicate that they are more concerned than the harvest managers about the potential adverse consequences of making the TB too large.If the TB is excessively big, there is a risk that some compartments may never be harvested.The results obtained do not show why the planners would like the TB to be larger than it is at present, and our data cannot be used to make valid comparisons between the two groups' perceptions of the current TBs or between the TB sizes that they would prefer.
The quoted statements relating to the size of the TB suggest that its absolute size is less important than its composition and balance.The respondents point out that the most important factor is that the TB should contain compartments that can be harvested in different seasons.This supports the conclusion that the balance between the properties of the compartments within the TB and the ground conditions within the compartments scheduled for immediate harvesting are more important than its absolute size.
These results raise questions regarding the extent to which harvest managers and planners are aware of the TB's contents.Almost all of the respondents said that the TB is stored on computers, in a format that is read using specific software packages or with the GIS software used within the company.Some of the respondents said that their company also maintains a paper version of the TB or a version in Microsoft Excel.The way in which the TB is accessed and searched affects employees' understanding of its contents and size, and therefore influences the way they use it.Alavi and Leidner (2001) point out that the source of competitive advantage is the application of knowledge rather than knowledge by itself.Importantly, the provision of suitable technology that supports the application of knowledge can influence the way in which it is used.The fact that both harvest managers and planners express a desire for a larger TB could be interpreted as a way of safeguarding their operations against unforeseen changes.The adoption of technology that would allow workers to rapidly search the TB and obtain an overview of its contents could enable more efficient management of its compartments.Around two thirds of the harvest managers reported that the TB was only accessible using a specific software package, while one third reported that it is maintained in the company's GIS program.The opposite trend was reported by the planners.This could indicate that even in cases where the two groups use the same software to examine the TB, they have a different understanding of the programs used to access it and therefore analyze and explore the TB in different ways.
The quotations show that some or all of the organizations have separate TBs for their own forests and for purchased volumes.These different TBs seem to have different problems, with different levels of severity.In addition, the value of the different TBs is variable.The use of multiple TBs introduces a new dimension to the implementation of strategies within the organization.Purchased volumes, i.e., trees located on land owned by organizations outside the company, must also be planned and these two sources of products must be balanced according to the company's goals.Each of these TBs must contain an appropriate mixture of compartments or otherwise complement one-another's contents.
A majority of the harvest managers did not rely exclusively on the data in the TB, and a relatively large proportion of the planners were willing to tolerate deficiencies in the reliability of the data that they entered into the TB.Both groups had at least some tolerance for errors in the data.While some level of inaccuracy in the TB data may be acceptable within the industry, it may be useful to consider how a tacit acknowledgement that the TB data may be unreliable would affect its use by planners and harvest managers.It is possible that one response to unreliable data would be to seek more resources in reserve, in this case by requesting a larger TB.The choices within an organization are affected by its employees' understanding of each other's quality decisions.When the people who collect data are not the same as those who use it, i.e., the decision makers, the quality of the data tends to suffer unless there is an awareness that it must be of high quality.If this awareness is lacking, workers within the organization often make decisions that might be optimal for their individual unit but is disadvantageous for the organization as a whole [14][15][16].In other words there is a risk that the acceptance of errors may limit the company's ability to establish a competitive advantage.Both groups agreed that erroneous information relating to ground conditions in a compartment is less acceptable than errors regarding its mixture of tree species or the volume available for harvesting.
A comparison of two different statements about errors in the TB data on the volume and species mix with compartments suggests that the harvest managers do not appreciate the planners' desire to ensure that the TB contains accurate information about the compartments.Except from the reasons that Storey et al. [16] give in their study, discussed in the previous paragraph, this may also be due to a lack of communication and trust between the two groups.However, it could also be due to a mismatch in how information is presented in the TB, or to organizational culture.The software might not be suitable to put in collectable data or to show needed data.This has not been part of the study and we can only speculate if this might be the case at some of the organizations.Table 3 showed that there is a high level of communication between the planners and the harvest managers regarding the contents of the TB.Harvest managers want to influence the content of the TB, while planners are keen to satisfy the harvest managers' demands.However, planners believe that the content of the TB should be determined by the forest plan rather than delivery plans more strongly than do harvest managers.Planners also assume that the TB is an important factor in the way the harvest managers organize the harvesting operations (Table 1).In contrast, the harvest managers regard the TB as a resource that is used to ensure that their delivery quotas are fulfilled and that if the compartments within the TB are insufficient for this purpose, it is acceptable to schedule compartments that are not in the TB for harvesting.In other words, harvest managers prioritize delivery plans over forest plans.
If the contents of the TB are chosen based on the demands of the deliveries rather than on the medium-term plan, then there is a break in the forest planning system and the harvest estimates made at long-term planning stage are ignored.According to the theory of the umbrella strategy, the realized strategy evolves when the environment changes [11], and therefore this break in the forest planning system cannot be seen as a sub-optimal decision by definition.But if the strategy is changed in a way that goes beyond the boundaries established by the company's management, there is a risk that the forest resources will be used in an uncontrolled fashion.While it may be possible to correct for this unplanned use when the next set of harvest estimates is made, there is also a risk that such impromptu changes will result in the over-exploitation of scarce compartments, creating a lack of certain attributes that may be hard to compensate for.There is a risk of an imbalance between supply and demand.It is therefore imperative for the company's management to specify whether the forest management plan or the harvesting plan should be given priority, and for all parties to be aware of how actions taken with respect to one plan will affect the other.If the forest plan is followed strictly, the scope for adjusting the delivery plan to match customer demand will be limited, while strict adherence to the delivery plan may affect the mixture of forest compartments and the ability to deliver products in the future.
The results obtained are not sufficient to determine how often organizations circumvent the established forest planning hierarchy.It is also not clear whether harvest managers only schedule the harvesting of compartments that are not in the TB in order to meet unexpected spikes in customer demand, or whether this behavior is implicitly accounted for within the medium-term plan.In addition to circumventing the company's forest planning hierarchy, the harvesting of compartments that are not in the TB jeopardizes the sustainability of the forest's productivity and means that the company may not be in control of its forests' economic output.To increase the likelihood that the company's operations will be conducted in a way that is compatible with both the forest plan and the delivery plan, both plans must be well understood at the local level.Several of the respondents to our survey said that the harvest estimates and the associated long-term plans cannot be trusted, and that the estimates are based on stands that cannot be found in the forests.This indicates that the harvest estimates are not considered valid at the local level, i.e., that knowledge is lost both during the gathering of input data for the harvest estimates and during the implementation of the plans.If the forest plans are not accepted and seen as legitimate, the "willingness" of employees to take decisions that contravene them is increased, even if their directives nominally require that they adhere to the forest plans [17].
The results obtained indicate that one part of the forest planning hierarchy, the TB, actually works quite well in many parts of the larger forest companies in Sweden, but in other parts the forest hierarchy is not strictly followed.The harvest estimates are economic optimizations that are created to maximize the company's income in both the long and the short term; if the inputs used to create them are unreliable or the resulting plans are not followed, the company's financial performance may be reduced.
According to Mintzberg and Waters [11], realized strategies generally exist at some point along a continuum between perfectly deliberate and perfectly emergent.The realized strategy for harvesting in Swedish forest-owning companies seems to deviate quite substantially from the intended strategy due to the harvesting of compartments that are not in the TB and the fact that harvest managers have some influence on the selection of TB compartments.On the other hand, the realized delivery strategies in these companies can also deviate significantly from the original intent.This is largely driven by factors relating to the company's operating environment, such as changing customer demands, and unpredictable weather.
In general, cooperation and communication between different units in an organization are regarded as positive things and should be promoted.However, if such communication leads to an undesired emergence of strategies that might compromise the firm's sustained competitive advantage, then the value of the communication must be questioned.According to the forest planning system, all compartments going in to the TB are supposed to be chosen based on the medium-term forest plan.However, only 40% of the harvest managers and 52% of the planners totally agree with the statement that the TB selection depends only on the forest plans and not on the delivery plan.From the perspective of the forest planning system, this is an alarming sign and may indicate that the system is not working properly.On the other hand, the results do not tell us whether the managers of the companies had issued directives prioritizing their short term goals over the objective of the long term goals.62% of the planners in charge of the input to the TB had some level of contact with the harvesting side of the organization when selecting TB compartments.Given the design of the forest planning system, this number is surprisingly large.The responses to our questionnaire did not specify whether these discussions focused exclusively on compartments that were included in the medium-term forest plan, but other results in the study indicate that the compartments chosen are not always those that are contained within the forest planning hierarchy.This is also indicated by the level of agreement with the statement that "sometimes I have to schedule compartments that are not in the TB", which only 39% of the harvest managers did not agree with at all.51% of the harvest managers said that they have been scheduling compartments from outside the TB into the short-term forest plan (10% did not provide a relevant response).This is remarkable in some respects, since the implementation of the forestry planning strategy is in the choice of compartment to harvest.If a compartment is selected that is not included in the forest plans, the forest planning system has been set aside, and short term goals have been prioritized over long term goals.Some level of disagreement regarding which compartments should be put in the TB is to be expected, since forest companies have two units with interest in the process that have different goals and may be making their decisions based on different information [12].The relative priority assigned to these goals should be specified by the company's management, and they should make their decision clearly known within the organization.If the management does not make a decision or communicates its goals poorly, then there will inevitably be deviations at the local level since staff will adopt ad hoc solutions to problems as they occur.It is important to note however that this process can be a useful and integrated element of the company strategy, especially in cases where there is significant variation in the operating environment at the local level.
Three competing companies participated in this study, and the responses from each company's employees were not separated in the analysis.It is therefore not possible to determine whether the forest planning and delivery strategies were implemented perfectly in the design of the TB in one of the companies, or whether the observed level of confusion is found in all Swedish forest owning companies.As such, the conclusions of this study may not apply to all of the participating companies.However, a general conclusion can be drawn: the establishment of clear directives on how the TB should be created and handled could increase the ability of the studied companies to implement their chosen strategies and thereby maximize their short-and long-term profits, establishing a sustainable competitive advantage.
The analysis of this study has mainly focused on the forest planning system.Further analysis from a strategic management point of view may give further insight in how the long-and short term strategies are realized in the work with the TB and may also give more concrete guidelines on how to handle the risks for unwanted emergent strategies that were identified in this study.
Because the questionnaire results were fully anonymised, it is not possible to determine whether the responses were distributed evenly over all three companies or whether all three companies are represented in both groups.However, since this is a study of how the forest planning is carried out in Sweden today, every respondent primarily represented themselves; their employer is of comparatively little importance.Our objective was not to evaluate a specific company or organization.In addition, all three companies are large and have a geographically dispersed workforce.As such, there may be differences in organizational culture both between and within the studied companies.The study did not aim to investigate how any specific organization manages its TB; instead, the objective was to determine how Swedish TBs are perceived by the people that actually work with them.
There is a risk that due to the short answering period, one or more units within the studied organizations would have been unable to respond to the questionnaire due to a large meeting or training exercise.However, none of the initial contacts within the companies indicated that any such event was happening during the time period in question.
When a compartment is harvested, several assortments are produced.The number of assortments will be greater than the number of tree species within the compartment.As a consequence, when one customer wants a larger delivery at one point in time, the increased harvesting will be accompanied by an increase in the output of various other products.This factor was not considered during this study.
There are reasons to believe that in the different organizations and also in different units of the organizations the words are used in different ways.The concepts of delivery and production plan can have different meanings for different respondents.This means that these words cannot be separated in this study.The demands from mills and customers can be discussed anyway mainly using the word "delivery plan" for all these plans, and only separating the words when needed due to the questionnaire.
Many of the respondents were concerned about the balance of compartments in the TB.This concern seemed to be at least partly motivated by the variation in ground conditions at different sites during different seasons.The time of the year and the prevailing weather conditions when the questionnaire was administered may have influenced the responses we received; it is possible that the results obtained regarding the preferred TB size might have been different if the study had been conducted at a different point in the year.
All of the respondents in this study were speaking for themselves rather than for their employer or the unit in which they worked.It would be interesting to investigate how the TB is perceived within specific subdivisions of a company.Interesting questions that could be examined in such a study include the following: do different individuals working with the same TB have the same opinions about it?What are the company's strategies for the work these people do?How is the balance between long and short term goals communicated in the organization?
In organizations where the planning process works properly and the TB is used as intended, what is the reason for this?How does this affect the company's deliveries and sales?
How are the contents of the TB shown in the software that is used to record and maintain it?The extent to which it is accessible and searchable should affect the way it is used by harvest managers and planners and increase their ability to use it effectively.
The sudden changes that are made to the short-term forest plan in response to changes in the operating environment are of particular interest: do they present a problem?How does the organization know when they start creating problems?In addition to these questions, such changes may indicate problems with the planning system-are these followed up on?The lack of adherence to the original plans is one thing, but such changes raise questions regarding the system as a whole; notably, is it really well suited to the forest planning process?If the planning of compartments from outside the medium term plan is performed even outside real emergencies, then the behavior is more deeply rooted Forests 2013, 4 572 within the organization.Is this behavior consistent with the strategy adopted by the company's management?If it is, then their strategy is not just a pattern but also a plan.However, if this behavior is not consistent with their strategy, its consequences are of interest.
From the analysis it can be concluded that the traditional view of the hierarchical forest planning system limiting the harvesting and delivery of wood products to the customers as depicted in Figure 1 is not reflecting the actual planning process in the companies.The results showed that the deliberate strategy as expressed by the forest planning system was adjusted and evolved in an emergent strategy as the harvesting operations needed to meet the delivery plans based on the requirements of the customers.As such strategy patterns were created which might be better or worse than the original deliberate strategy.What is important according to the umbrella strategy [11] is that the employees working with the TB have competence, guidelines and an organizational culture that ensure that the strategy pattern is not jeopardizing the resources of the company as the results identified such risks in today's practice.An alternative way to depict the forest planning system and its interaction with the harvesting planning system is given in Figure 8 as a visualization of todays practice and a reminder for the need of management's guidelines.
