ISO 50001: 2018 and Its Application in a Comprehensive Management System with an Energy-Performance Focus

: Business progress and human development are linked to the e ﬃ cient management of energy resources. The research in this paper contributes to the generalized application of good practices that reduce the vulnerability of companies. The research focuses on energy e ﬃ ciency through comprehensive management systems (CMS), and “thought based on risks and opportunities”, considering the discussion about the revision of ISO 50001:2018, the basic approach of the model and the route to implement CMS for quality, safety and health in the workplace, environmental management, energy e ﬃ ciency, and other risk components. This implementation route, with the acronym CMS QHSE3 + , places special emphasis on the functions of strategic planning, operational and risk management, and controls, as well as on deliverables and references to examples, templates, standards, and documents, to facilitate its application general in small and medium enterprises and in the management of energy e ﬃ ciency.


Introduction
In line with international standards on management systems, ISO 50001 Energy Management Systems (EnMS) stipulates certain energy saving and efficiency requirements that companies must meet. The ISO/TC 301 Technical Standardization Committee, Energy Management and Energy Saving, reviewed this standard and published it in 2018 [1][2][3], at the request and requirement of the United Nations Industrial Development Organization (UNIDO), the International Partnership for Energy Efficiency Cooperation (IPEEC), and the Clean Energy Ministerial (CEM) [4,5].
The ISO 9001:2015, ISO 45001:2018, and ISO 14001:2015 standards, together with ISO 50001:2018, have special relevance for organizations around the world, because they bring together the good management practices required by manufacturing, business, and service institutions to meet the requirements of interested parties, prevent risks, and have a strategic approach towards the integral generation of value, energy efficiency, and sustainable success.
For this reason, institutions must promote and guarantee energy efficiency and cost-effective management internally and/or with their stakeholders. Both energy resources and their efficient management are increasingly weighted in the ethical field, in the rational balance among costs, expenses, achievements and benefits obtained during the CMS implementation projects, developed with the model and approach presented here. Section 3.5 contains the discussion on the results obtained in terms of energy efficiency. Section 4 closes the document with the conclusions, and Annexes A are added, which include the complementary information: A1: The logical structure of the family of standards in force and in development ISO 50000. A2: The general illustration of the application of the model and the route of implementation. A3: the list of acronyms used in the paper.

Revision of ISO 50001: 2018
The high-level hierarchical structure, established in Annex SL of ISO/IEC Directives (2018), insists that all standards concerning management systems have 10 chapters with a homologous architecture [3,19,20]. Figure 1 shows the hierarchical structure of ISO 50001, which correlates the aspects relevant to the review process based on the plan-do-check-act (PDCA) cycle. The blocks in this figure correspond to Sections 2.1.1-2.1.6 of this paper. Section 2.1.7 highlights the key issues that should be considered in future revisions or documents of the ISO 50000 family.
2.1.2. Requirements Related to "Planning Management" ("P" Chapters of the PDCA Cycle) The chapters associated with "Context", "Leadership", "Planning" and "Support" are assigned to parts 4, 5, 6, and 7, of the standard, respectively. These chapters, which constitute the "P" chapters of the PDCA cycle in Figure 1, maintain the flow logic in the business domain and its environment, direction, commitment to leadership, and the allocation of resources.
2.1.2. Requirements Related to "Planning Management" ("P" Chapters of the PDCA Cycle) The chapters associated with "Context", "Leadership", "Planning" and "Support" are assigned to parts 4, 5, 6, and 7, of the standard, respectively. These chapters, which constitute the "P" chapters of the PDCA cycle in Figure 1, maintain the flow logic in the business domain and its environment, direction, commitment to leadership, and the allocation of resources.
ISO 50001:2011 has a new topic that encompasses the knowledge and understanding of context, focusing on the interest groups related to energy management. This topic analyzes the operational risks/opportunities (R/O), strengths, and potential internal and external problems of the energy management.
This standard emphasizes the decision-making participation of top management during the cyclic planning, action, feedback, and adjustment activities. The first three of these activities constitute the MMAE management. The R/O concerns, which initiate the planning and formulation of goals, are approached from a context-management perspective. Management planning priorities are determining the energy baseline in conjunction with the key performance indicators (KPI) for energy, the planning and management of R/O, and the activities highlighted in the energy review. The planning includes the collection of data on energy management, e.g., energy characterization, load censuses, energy diagrams, diagrams of energy consumption versus operations and production over time, and others [20,21].
Requirements related to communication of energy performance and Energy Management System (EnMS) improvements among stakeholders are also established. • Axis of analysis of the process components (workers, materials, methods, machinery, measurement, and environment) versus the risks and controls related to energy efficiency; • Axis of process design, with particular emphasis on services, sources, uses, generation, distribution, measurement, and control of energy efficiency; • Axis of energy-efficiency management associated with the purchase of services, equipment, and products. In this form of management, an organization interacts with suppliers, contractors, or allies that develop activities for, or on behalf of, the organization.
2.1.4. Requirements of Chapter 9 ("Check" (C) Part of the PDCA Cycle) Although there are no significant changes from the previous version, the new version emphasizes that MMAE must drive the integral management of R/O toward "understanding, taking decisions and acting with intelligence to achieve sustainable success" [22].
Perhaps for this reason, ISO 50001:2011 is an exemplary standard for management systems, establishing one of the most robust mechanisms for measuring, monitoring, analyzing, and evaluating the energy efficiency and EnMS. On the other hand, specific management and technology developments have improved the definition, implementation, and management of indicators associated with benchmarks and energy performance. These developments include (but are not limited to) reduction of thermal energy, higher efficiency of heating and insulation, higher percentage of thermal saving, economic saving, reduction of carbon emissions, and increase of renewable energies [23][24][25].
2.1.5. Requirements of Chapter 10 (Correction, Maintenance, and Improvement Actions of PDCA) In ISO 50001:2018, the approach for improving the Energy Management System (EnMS) and energy performance is complemented by improving the three parameters of the management review: "Convenience", "Adequacy", and "Efficiency" of EnMS. This improvement includes:

•
The development of energy-saving actions in R/O ( [26]); • The analysis of MMAE results and the general performance, which should fulfil the objectives and goals of the EnMS; • Analysis of the external and internal factors of the context; • Output of feedback mechanisms such as audits and the EnMS review; •  The progress and effectiveness of actions related to corrections, responses to incidents and  complaints, requirements, breaches, and corrective actions. This block includes the improvements related to energy planning, along with particular aspects of technological improvements associated with (for example) spatial planning and integrated energy in public, urban, and private spaces, automation, information and communication technologies (ICT), intelligent data analysis, optimization and control methods, and the integration of energy-efficiency management with environmental-management planning.
All measures undertaken must aim to reduce the vulnerability associated with the energy efficiency, which directly involves the operational control component.
When effectively implemented, these measures can be regarded as improvement actions that ratify the good practices contained in the different disclosure documents promoted by the Clean Energy Ministerial, by EMAS in different specific sectors, by the sponsorship of the European Economic Community, and by other entities committed to energy efficiency, pollution prevention, and environmental protection [27][28][29][30].

Changes to Annex A
The sequence of Annexes A1 to A10 in ISO 50001:2011 is adjusted to suit the new chapters. Specific guidelines are proposed for the approach to energy planning, actions that address the performance-related R/O, the energy baseline, indicators and the energy review, and the metrological control of the critical measurement equipment associated with the relevant uses and consumption. Annexes A-6 and A-9 also propose specific guidelines for MMAE, auditing, and management review. This feedback management follows a systematic approach based on the information, facts, and statistical analysis of the performance. The topics that should be explicitly considered in future revisions of ISO 50001, or in other standards of the ISO 50000 family, are labeled "a" to "r" in Figure 3. These topics are intended to clarify, reinforce, integrate, or include the following contributions: a.
In the introductory chapters, a structural map of the standards of the ISO 50000 family would reinforce the overview and the fundamental purpose of standard ISO 50001:2018. Another section outlining the principles of integral management and sustainability, similar to the guide contained in ISO 31000: 2018, would also be helpful. b.
The context study should include a strategic and comprehensive analysis that considers the market, business, interest groups, and the geopolitics of energy. c.
The annexes could present the risk management and opportunities of energy efficiency (E2) from an integral and strategic point of view, including the planning and control of product lines, process design, projects, and business approaches. d.
The effective operation of the EnMS demands the coordinated deployment of strategic, tactical and operational levels that align the business culture with sustainable success. e.
A strategic management approach for studying scenarios and trends should be included. This should account for the volatility of the macroeconomic and geopolitical conditions [31].
f. The vision that the organization wishes to build must be correlated with the strategy of efficiency and energy saving, and with the organization's survival in the market. This correlation must be explicitly defined and well disseminated. g.
The awareness-related requirements should highlight the importance of the organization's staff understanding the challenges of energy efficiency, knowing their roles in relation to the objectives, and knowing the approach of the programs that support energy management, directly related to their processes. h.
Within the section corresponding to the configuration of plans and programs for energy management, it is necessary to make explicit reference to new technological developments to optimize the integration of the EnMS component with the variable energy demand, and the functionality of the intelligent network in terms of interaction with: Higher-level energy management platforms, such as support systems for urban energy management decisions [32,33]. Peer-to-peer energy management platforms, such as support systems for district energy management decisions [34][35][36], and Lower-level energy management platforms, such as SCADA subsystems or devices [37,38].
i. The recommendations annex should formulate an integral management policy oriented towards the prevention, compliance, and improvement of the QHSE3+ performance. j.
Chapter 5 would benefit from establishing specific objectives for energy efficiency, which should be aligned with comprehensive policies and strategic objectives. k.
The "Project Management and Development of New Products and Businesses with Perspective of Performance and Energy Saving" approach should be included in the planning and control requirements. l.
In the operational control of energy efficiency (Number 8.1), an integral perspective linked to operational excellence and the control of each process is demanded. m.
The management of organizational development and culture for energy efficiency (E2) needs an explicit reference to ensure the continuity, projections and effectiveness of the EnMS. n.
The function of purchases and supplies should include the requirements of energy performance. o.
The requirements of "knowledge management" and "lessons learned" must be explicitly defined so that the documented information is constituted in the best know-how of the processes. p.
The MMAE approach requires a comprehensive perspective with feedback on the competitive performance of the energy efficiency in product lines, processes, and projects. The planning approach of internal audits should account for the R/O. q.
A section with reference to websites in the annexes, as well as templates, tools and links, such as those found in Forum 27k [39] or IEC 31010: 2009 tools [40], would be helpful. Also, an explicit presentation of the ISO 50004:2014, ISO 50006:2014, and ISO 50015:2014 [41][42][43] sections that support the interpretation and application of the requirements would encourage good practices, thereby improving the performance, use, and consumption of energy (See Scheme A1 in Appendix A). r.
The text of the standard must clarify the purpose of the EnMS; that is, the creation and protection of value in sustainable competitive success. A key element of this purpose is savings and energy efficiency.

Risks and Opportunities-Based Thinking in Management Systems
The management systems of institutions and companies may be unaware of the ISO standards related to management. A management system should harmoniously integrate processes, people, resources, and methods in a coherent manner, to achieve the fundamental purposes and strategic objectives of sustainable success.
Notwithstanding, ISO standards that establish requirements and recommendations for the components of a management system are justified, because they enable transference of technology, by which good practices can be promoted, disseminated, and demanded in organizations, at both the strategic and operational level of processes and projects. In this way, technology helps to reduce vulnerability and improve the performance of the organization.
Good practices mainly focus on the creation and protection of value, based on planning and control management at the strategic and operational levels of the organization. Good practices that support the ISO norms on management systems are based on risks; in this context, risk management means the anticipation and control of what can and should occur in the processes and business practice. Risk management should strive to meet the strategic objectives, purposes, and commitments associated with the projects, processes, products, and services. Figure 3 summarizes and correlates the concepts of risk and the risk management process, and the application of risk management at different levels of an organization. Risk management involves strategic decision making on the direction of business and institutions, decisions in planning and project development, decisions in the management of processes, products, and services, and decisions in the interaction of people with their environment and stakeholders [22,44].
The cycle of the risk management process is similar to that of opportunities, and must be implemented on a regular and systematic basis. Depending on its topic, or nature, each risk is managed at different levels (see Figure 4). Especially, each risk requires time to collect and analyze the information, to make decisions, and to plan, execute, feedback, and successfully complete the actions required for the effective management of the risk or opportunity".

Whether a decision is made by an operator, a person interacting with a client, a process or project developer, or is the corporate decision of the management team, the successful Whether a decision is made by an operator, a person interacting with a client, a process or project developer, or is the corporate decision of the management team, the successful implementation of "thought based on risks and opportunities", depends on the intelligence of the information, the competences of the decision makers, an integral, inclusive, dynamic and structured approach to management, and consolidation of the principles and values of prevention in the organization. It also requires the leadership, commitment, and direct participation of the steering group [22,44,45].

Conceptual Model of CMS QHSE3+: Application of Systemic Design
Based on general systems theory, conceptual model design and systemic concurrent engineering are applicable to all types of products, services, organisms, and systems [46,47]. Private design schools have integrated graphic design into their functional, ergonomic, and formal components. Exploitation, management, evolution, and mutation objectives of these three components can be developed using the systemic approach.
This strategy was adopted by the Latin Design Network. The Magazine of the International Design Research Network (rdis), the Latin Design Network, has been integrating the work and efforts of design schools and researchers from Argentina, Brazil, Chile, Colombia, Spain, Italy, Mexico, and Venezuela, among others [48][49][50][51].
In the present investigation, the conceptual model of the CMS QHSE3+ was configured using the systemic design methodology. The configuration was based on a functional, ergonomic, and shape design. The final graphic result is shown in Figure 5. implementation of "thought based on risks and opportunities", depends on the intelligence of the information, the competences of the decision makers, an integral, inclusive, dynamic and structured approach to management, and consolidation of the principles and values of prevention in the organization.

The final graphic result is shown in Figure 5. Figure 5 shows the ten structural elements composing the configured model [52].

Steering Core
The steering core is represented by a star representing the direction and strategy of sustainable success. The steering core is integrated and symbiotic with the core business management associated with the development of products and services that characterizes and differentiates organizations.  Figure 5 shows the ten structural elements composing the configured model [52].

Heart of Talent and Culture
The heart represents the managements of culture, organizational development and knowledge, along with the development of skills, and the strengthening of the social and human sense in the entrepreneurship projects of all organizations seeking sustainable success.

Intelligence Breastplate, Risk Management, and Operational Planning
The three-layer breastplate gathers the three fundamental fronts of the CMS: the intelligence of the information and the businesses (first layer), the integral risk management (second layer), and the operational planning (third layer). The third layer is fed by the second layer, and determines the tasks to be completed and what will be controlled in the QHSE3+ components of the different processes.
The model also includes five arms (components D-H) for the QHSE3+ components, as described below. The arms correspond to the application of good practices in operational planning (that is, the QHSE3+ components), considering the high-level structure (HLS) defined by ISO for all management systems standards.
The HLS is based on review processes initiated in 2013, which generated the updated ISO versions

Component Q-9k (ISO 9001)
The Q component is the blue arm in the model, which corresponds to the operational control of good practices in the quality management of products, services, and processes. The aim is to prevent failures and nonconformities in the design specifications.

HS Component-45k (ISO 45001)
The HS component is the red arm in the model, which corresponds to the operational control of good practices in health and safety management. The aim is self-care and the prevention of occupational accidents and diseases.

Component E-14k (ISO 14001)
The E1 component is one of two green arms in the model. It corresponds to the operational control of good practices in environmental management. The aim is environmental care and pollution prevention.
The E2 component is the other green arm in the mode, which corresponds to energy efficiency management. The aim is to prevent the non-rational and inefficient use of energy resources.

Plus Component (+)
The plus component is the yellow arm in the model, which corresponds to the management of other specific risks that depend on the nature of the organization. For example, some organizations may need to mitigate safety risks, information security risks, smuggling, drug trafficking, or illegal trade. Finally, the model structure includes two axes of dynamics, as described below.

Feedback Axis
The feedback axis covers all components of the system, including aspects related to auditing, indicator management, monitoring, measurement, analysis, and evaluation. It also covers supervision, petitions, complaints, claims, voice management of the special interest groups, and other relevant items.

Axis of Improvement and Innovation
The improvement and innovation axis closes the PDCA cycle of the model. Improvement and innovation involves planning, implementing, checking, verifying, receiving feedback, and using the feedback to maintain, correct, prevent, or improve the past performance. Improvement and innovation is integral to the management of all organizations and businesses. The feedback elicits immediate maintenance and corrective actions, and short, medium, and long-term actions of innovation, improvement, and progress.

Project Approach Applied to the Implementation of CMS QHSE3+
The application of good practices in project management is gaining importance daily. Techniques that enable the effective management of the various risks in projects, particularly in projects that implement a CMS with QHSE3+ components, are demanded. Two schools devoted to project management have been consolidated in the past two decades: The PMI Project Management Institute, and the Logical Framework School, which is linked to the World Bank and the Inter-American development Bank (IDB).
The developments of logical framework/IDB and the PMI Project Management Institute are rarely applied to project planning, launching, development, evaluation, and control in the implementation projects of management systems, or in the corporate projects of SMEs [63][64][65][66][67].
According to the statistics, the certification projects of management systems in SMEs are also unfavorable. For instance, the Standish Group in the Chaos Reports, carried out annually since 1994, reported that failed projects constitute between 17% and 25% of the total projects associated with ICT or knowledge management. As a reference value, we suppose that 21% of management-systems projects in SMEs are unsuccessful. We also consider that the CMS QHSE3+ implementation project is small-to-medium. In the Chaos Reports, the failure statistics of this type of project easily exceed 40% [10, [68][69][70][71][72][73].
In the Latin American environment, the IDB and its Multilateral Investment Fund, the Chambers of Industry, and the Commerce of Central and South America have gathered the sustainability statistics of clusters ISO 9000 and ISO 14000 projects. The number of SMEs that have successfully completed their certification projects does not exceed 60% [11,70,73].
Under this premise, different principles and elements of the logical framework project approach were adopted for configuring and implementing the CMS QHSE3+ model. The problem and objectives/deliverables trees were constructed under the project management body of knowledge (PMBOK) guidelines. The implementation project, task breakdown structure, implementation route, and project plan were also established in PMBOK (examples of the project tree and the breakdown structuring of the implementation path are presented in Section 3).

Approach for Developing the CMS QHSE3+ Implementation
The current trends of the SMEs and projects implementing management systems highlight the importance of supporting entrepreneurs and their SMEs. The provided tools should facilitate and encourage the development of projects applying the good practices contained in the ISO standards 9000, 45,000, 14,000, 50,000, and others, to each of the QHSE3+ components.
The authors have participated in the development of a guide for comprehensive risk management and in the configuration of a conceptual model for a CMS QHSE3+, which have been adopted by medium-sized Latin American companies of the manufacturing, pharmaceutical, services sector health, in Family Compensation Funds, and in port logistics operation, among others. (See examples of results in six types of companies in Section 3 and in . The route of implementation of the CMS QHSE3+ model, presented in this paper, emphasizes issues related to the energy efficiency component (E2), in accordance with ISO 50001:2018 [22,45,52].
When designing an implementation route, entrepreneurs must understand the importance of a single management system that supports the achievement of their strategic purposes.
Under the banner of integral management, this system must guarantee that all projects, processes and products of the company adopt the good practices stipulated in international reference standards.
These practices should focus on risk prevention, opportunity exploitation, excellence in operations, and sustainable business success. For this purpose, the company need not certify all components in the QHSE3+ approach, but must cover all the fronts and priorities that generate vulnerability for the organization [45,52]. Figure 6 presents the various stages of the CMS QHSE3+ implementation project. This comprehensive perspective covers any conjugation of standards on management systems, such as complementary approaches to ISO 50004:2014, by integrating the requirements and configuration of the CMS, and prioritizing the strategies deployed through the processes and projects of the organization.

Thus, although none of the companies submitted to certification with ISO 50001, their management systems were certified or accredited in the quality and regulatory components, and have an integral approach based on strategic management, combined with planning and the operation of the processes, with a perspective of risks in the QHSE3+ components. Thus, in all projects it was possible to show a return on investment, measured in specific terms of vulnerability reduction, reduction of energy consumption, and percentages of progress in compliance against the requirements of the applicable QHSE3+ standards.
It is also important to highlight as a result, the innovative character of the model and tools, which are available to entrepreneurs and the user community of the management systems implementation processes.

Problem and Objectives Trees of the Project (Methodology of the Logical Framework)
At the beginning of any project, we must define the problem to be solved, and identify its causes and consequences to minimize the planning.
The logical framework for Project Management developed by UNIDO, World Bank, the Food and Agriculture Organization, and the IDB, provides a simple methodology for defining the project objective, the large work blocks and types of resources required, and the expected results and impacts [64,65,67,71]. We begin the exercise by posing two key questions associated with the research objective: • What is the central problem that lowers the sustainability of the entrepreneurship and certification projects of the integral management systems of the organization? • How can we improve the business management, achieve sustainability, and reduce the uncertainty and vulnerability of the business while managing its water and energy usages?
The results of applying this methodology are shown in Figure 7. Shown are the causes and consequences of this situation, and the need to develop a basic work model for management. operation of the processes, with a perspective of risks in the QHSE3+ components.

For this purpose, we require a basic integral approach and easily applied tools by which organizational staff can determine and apply good practices over the cycles of configuration, Figure 7. Problem tree analysis. Source: Application of the logical framework for projects [64,65,67,71].
For this purpose, we require a basic integral approach and easily applied tools by which organizational staff can determine and apply good practices over the cycles of configuration, planning, development and consolidation of their entrepreneurship projects, and hence guarantee sustainability of their companies. Figure 8 shows the tree begun from the problem tree, which defines the project objective, the expected results, and the most relevant tools, resources and action fronts.
With this approach, a template was generated with instructions for completion, as a tree construction tool, which was used in all projects, as a basis for the identification of the problem, the scope of the project, the activities and key resources required, the objectives and impact indicators. In addition, it was also used as a basis to prepare the Constitution Act or Project Charter of the CMS implementation plan QHSE3+. In this way, it was contributed to companies and entrepreneurs, in terms of clarification of the purposes and general approach of the project. planning, development and consolidation of their entrepreneurship projects, and hence guarantee sustainability of their companies.

Work Breakdown Structure, Route, and Deliverables for Implementating the CMS QHSE3+ Project (Emphasis on Key Products Associated with the E2 Component)
One of the most useful concepts in project management is the work breakdown structure (WBS) of packages and work activities. The integration of these packages and activities gives the key deliverables that solve the problem objectives of each project [65,68,74].
Schemes 1 and 2 show the details of the WBS. Deliverables that must be generated at each stage of the project are shown. These tables were configured under a comprehensive QHSE3+ approach, focusing on the energy efficiency component E2. Deliverables are grouped into four axes associated with the balance score card [75], from the bottom up, so that talent and competency Axis 1 corresponds to the last row, and they go up to the extent that the first axis feeds the second, the second to the third, and the third to the fourth, like this: Axis 1: Human talent and competences, for the development of processes. Axis 2: Processes that make up a system and generate products and services, directed to clients and interest groups.
Axis 3: Clients and interest groups, which generate income and added value for the strategic and financial purposes of the business Axis 4: Strategic and financial. One of the most useful concepts in project management is the work breakdown structure (WBS) of packages and work activities. The integration of these packages and activities gives the key deliverables that solve the problem objectives of each project [65,68,74].

Configuration of the CMS, its processes, the decisional information system and external and internal communications.   It is important to note that in addition to the general conception of the CMS QHSE3+ model, this WBS has been one of the innovative tools with the greatest impact and utility in the projects carried out by the authors, both for the consultants, as well as for those responsible for the administration and the effective development of CMS implementation projects, on the side of companies; taking into account that it allows:

•
To have a complete vision of the project and its stages, as well as the deliverables that must be generated in each one.

•
To make specific adjustments based on the status of each company, specific applicable requirements, the regulations of the business, or exclusions.

•
To have a good general starting point to structure the master plan or project schedule, and control its effective development.

•
Align the strategic management of the business with the operational and integral risk approach QHSE3+ of the processes, insofar as the stages follow a PDCA cycle, which considers strategic planning, operational planning, "thought based on risks and opportunities", the process approach, the monitoring, measurement, analysis and evaluation MMAE, and the improvement actions accordingly.

Stage Zero: Preliminary Project Configuration
Applying the project management tools of the logical framework and PMBOK, this stage constructs the problem tree and the objectives, the WBS, the project scope and charter, and the project needs and context. It also preliminarily assesses the CMS QHSE3+ and organizes the project development, including the energy team.
The phases and detailed route of the project are presented in Schemes 1 and 2. The created WBS displays the sequence of the deliverables that meet the QHSE3+ requirements along each axis and in each phase of the project.
Reference documents, tree templates of the logical framework, the project charter, and the support tools can be found in [22,52,58,59,68,70]

Stage I. Initial Review and Context of CMS QHSE3+
Stage I includes the initial context study, the analysis of the legal and regulatory status, the analysis of the gap between the QHSE3+ and the baseline, the status determination of the KPIs, and an energy review. This phase also determines the scope of the CMS and defines the project in more detail, considering the WBS, schedule, and budget of the project. In parallel with stages 0 and I, the support activities related to awareness, training and the general communications of the CMS QHSE3+ are planned, developed, and evaluated.
Reference documents, templates, examples, good practices and methods of energy savings, context analysis and reputation, legal requirements management, initial status review, baseline, KPI status, and project master plans are provided in the following sources: • See also www.iso.org/iso-45001-occupational-health-and-safety.html; www.lms.quaratechnology. com in the Bank of Knowledge of the GIR Guide, www.iso.org/committee/54960.html, and http: //www.iso27000.es/sgsi.html.

Stage II. Management Planning of CMS QHSE3+
Stage II formulates the strategic initiatives for sustainable success and competitiveness, and defines the objectives and corporate projects.
This stage highlights the following results that guide the strategic direction: policy mandate, the principles and CMS approach, the strategic map and the QHSE3+ projects, planning for strategic R/O management, planning for business continuity, and planning for change management and innovation. For specific technical aspects of the operational planning of energy management, prediction of energy consumption, planning, and optimization of the Energy Management Systems in particular contexts, and reducing the vulnerability to risks of the energy efficiency (E2) component, the reader is referred to [79][80][81][82][83][84][85][86][87][88].

Stage IV. Operation of CMS QHSE3+
This stage applies the dispositions planned in the previous stages. In an integral approach, it outputs the deliverables and evidences related to business development, objective compliances, and vulnerability reduction (strategic and operational).
This stage also evaluates the KPIs related to improvement of QHSE3+, and validates the CMS manual, maps, plans, QHSE3+ programs, and records of training and skills qualifications of the staff.
In additional to references listed in stages 0, I, II, and III, the following websites can be accessed at this stage: www.iso27000.es/sgsi.html, www.lmsquaratechnology, and www.iso27001security.com/ html/toolkit.html. These sites, which are publicly available, present a series of examples of templates, documents, manuals, plans, maps and toolkits.

Stage V. Evaluating the Performance of CMS QHSE3+
This stage provides the feedback on the performance of CMS QHSE3+. The feedback considers the planning and development of audit cycles, the follow-up and closure of corrective and improvement actions, management of non-conformities, incidents and reporting systems (requests, claims, and satisfaction), strategic and operational management of MMAE in the CMS, the QHSE3+ components and business lines of the CMS, and the analysis of uses, resources, and energy.
The annexes of the standard guidelines provide the implementations of the components, and the QHSE3+ requirements standards referenced in the previous section provide the MMAE guidelines. The aforementioned website portals include the tools and checklists for MMAE, and comprehensive diagnostics and audits of the QHSE3+ components.

Stage VI. Improving the CMS QHSE3+
This stage presents the challenges and decisions on the future of the CMS QHSE3+ and each business line. The conclusions are based on the above-mentioned feedback mechanisms and a managerial review. This stage monitors the adequacy, convenience, effectiveness, innovation, and progress of the company, its energy and environmental performance, its advances in integral security, and the maturity of its CMS QHSE3+.
Valid recommendations and methods for this stage and for each QHSE3+ component in this stage are available in the reference documents listed in the previous steps. This stage closes and restarts the operation cycle of the CMS, and integrates the challenges and decisions with the strategic planning actions and corporate projects, as well as with the operational planning of processes and products.
During the implementation processes of a CMS, the energy efficiency component faces many barriers and difficulties that are closely linked to pessimism, preliminary resistance to change, or because in some cases implementing of energy efficiency is not cost-effective or has little financial benefits.
These difficulties are generally resolved under guiding examples and consistent planning, which require discipline, participation, innovation, commitment, and sustained leadership. In addition to delivering technical benefits, such dedication will optimize the financial performance of the organization and generate a culture willing to measure and assume responsibility for its results and achievements, implement energy savings and risk prevention, and research alternatives for sustainable success and mutual benefit [12,20,22,[83][84][85][86][87][88][89][90][91][92].

Role of Energy Efficiency (E2) in the Leverage of CMS QHSE3+ and R/O Management
In recent decades, the increase in unit costs of energy, fuels, and water has been evident for manufacturing and service companies, for the commerce sector, and for the community in general too. This has been caused by various factors among that includes the increase in population and demand as well as the depletion of water resources and organic fuels.
Accordingly, the use of water and energy has a significant impact on the costs and expenses of those organizations in which their operations involve a considerable and permanent demand of the resource. At the strategic level, many organizations are seeking alternatives that reduce the vulnerability to price volatility, and lower the reliance on oil, fuels, water, and energy in general.
However, as pointed out by Cooremans [93], a systematic and continuous dedication to investments and projects in energy management has not yet been generalized within investment maps and corporate cultures. The exceptions are manufacturing organizations or operations using furnaces, mills, or transport infrastructure, in which energy or fuel is among the most important items in the budget.
In fact, investments and energy risks are not always labeled in strategic projects, and although many governments have stipulated the development of energy-saving plans and projects as a legal requirement, only a few have effectively managed their energy usage in practice. Most companies merely impose controls on their billed consumption as a secondary administrative measure [91,92].
Notwithstanding, when organizations adapt their culture toward "thought based on risks and opportunities", and develop projects that improve their energy efficiency, they are rewarded with an attractive investment return that can leverage other important investments through comprehensive management

General Achievements and Benefits of the Research
The present research will provide entrepreneurs, SMEs and interested sectors with the following services: • A matrix that pedagogically presents the logical and thematic structure of the ISO 50000 family of international standards (Scheme A1 Appendix A). The main and complementary blocks display the vocabulary, reference framework, requirements, and general guidelines. The matrix includes the short-and medium-term strategic approach of the work plan of the TC 301 Committee, which emphasizes good practices of a general nature and those of specific sectors. By adopting these practices, organizations can measure their energy-saving performances and deploy and promote the ISO 50001:2018.

•
An inventory of the aspects not considered in the current revision was presented in a graphical operation model of the EnMS and the CMS QHSE3+. This model illustrates the correlation, application logic, and relationship with the structure of the reviewed document. It emphasizes the need for a comprehensive management system and risk management that considers the strategic management level, projects, process operations, and new business developments, products and services (Section 2.1.7 and Figure 2). • A tool that constructs the problem tree was demonstrated on the CMS QHSE3+ implementation project, with identification of the problem causes and implications.

•
As a general application, the tree-constructing tool was demonstrated on the central objective of the project. The expected results, identification of the key issues, and the blocks corresponding to the developmental work packages of the project were revealed (see Figures 7 and 8 of Section 3.1).

•
The implementation route of CMS QHSE3+ was established using the WBS of the implementation project, which allows us to visualize, correlate and understand the stages, deliverables and axes of the project. The WBS was obtained as follows: (i) Human talent and competencies, (ii) processes and management system products, iii) market and stakeholders, and iv) financial and strategic management. From this WBS, one can develop tools for the master control of projects (see Section 3.2 and Schemes 1 and 2).

•
The implementation route was described with reference to the documents and website portals that provide the guidelines, examples, templates, and tools for developing and applying the deliverables of the project (numbered 1-40 in Schemes 1 and 2; see Section 3.2).

•
The obtained achievements and results will determine the course of the investigations and the subsequent actions for disseminating, expanding, and enlarging the instruments generated by the research, thereby promoting sustainable success in entrepreneurship efforts.

Results Related to Energy Efficiency
The model and its support instruments were preliminarily evaluated in six types of organization: family compensation services, health services in a municipal hospital and a local clinic, a pharmaceutical laboratory, port operations, and glass production.
The model improved the focus, clarity, ease of application, consistency, didactic utility, and general logical structures of the organizations. The achievements are listed below and summarized in Schemes 3-5.
The model and its support instruments were preliminary evaluated in six types of organizations: Family compensation services, health services in a municipal hospital, a local clinic, a pharmaceutical laboratory, port operations, and glass production.   The model allowed improving the focus, clarity, ease of application, consistency, educational utility, and general logical structures of organizations, in relation to their comprehensive management system. The achievements are summarized in Schemes 3-5 that have been configured as follows:

CHARACTERISTICS OF THE SELECTED COMPANIES´ CMS. ACHIEVEMENTS IN COMPONENT E2
In Scheme 3, the results corresponding to the first two companies are grouped: Family compensation services and health services in a municipal hospital In Scheme 4, the results corresponding to the following two companies are grouped: Health services in a local clinic and pharmaceutical laboratory In Scheme 5 the results corresponding to the following two companies are grouped: Logistic services of operation in port and glass production.
The three tables have 9 blocks of rows, which correspond to the categories of analysis considered, ranging from the comprehensive approach of the management system, in Row 1, to the reduction in energy consumption per capita, in Row 9. The achievements obtained are listed below: • Row 1 describes the current approach of each CSM. The manufactures of pharmaceutical products and the family health and compensation services are regulated. In all regulated cases, the management system focuses on the regulatory framework and the planned strategy. In the production of glass containers, the regulation ensures safety in the food chain. The blocks of Rows 2 and 3 also reveal that although none of the six companies were certified in the energy efficiency (E2) component of ISO 50001:2018, they all adopted energy management programs under the approach of integral risk management (MMAE dynamics of their EMS and a legal obligation to implement energy saving plans). Among this group of companies, one was certified with good manufacturing process by the Food and Drug Administration, and another was certified with ISO 22000. • Row 4 shows the degree of implementation of ISO 50001:2018 under the classification criteria, which require evidence of improvement to 100% in each requirement. The results range from a low level of implementation (31% of companies) to a medium-high level of implementation (69% of companies). None of the six companies were interested in acquiring the formal ISO 50001 certification. • Rows 5-7 present the average reductions in vulnerability to energy efficiency risks in the first, second, and third years, respectively. The results ranged from 9.60% to 18.60% in the first year, from 9.4% to 11.5% in the second year, and from 4.60% to 14.30% in the third year.
Although these behaviors show no regular pattern because they are governed by different variables and conditions, the percentage reduction is expected to be highest in the first few years of implementation.
The vulnerability reduction indicator is calculated as where DismVul denotes the percentage decrease in vulnerability after implementing anti-risk measures, Po i and Go i are the initially assessed possibility and gravity, respectively, and Pf i and Gf i , are the final possibility and gravity, respectively, after adopting the planned measures. Most of the good practices adopted by this group of companies are embodied in the standards and guidelines of EMAS, and are highlighted at the sector level by Laskurain et al. [26,93]. • Finally, Row 9 presents the average reduction valuations of the per capita energy consumptions between year 1 and year 3. The energy reductions were satisfactory and ranged from 16.30% to 42.60%.

Conclusions
In the first instance, it can be affirmed that the objectives of the research that supports this paper have been met, taking into account the products generated during the development of the research, and the actions taken for the application and validation of the model, methods and tools configured for its implementation in different companies of goods and services (Schemes 3-5).
In this way, simple pedagogical instruments are made available to the business sector and SMEs, so that they apply in a generalized manner the good practices of the international ISO standards, in the CMS QHSE3+ comprehensive management systems, with a holistic perspective of risk management, opportunities and energy efficiency, at strategic level, of business lines and operational processes.
On the other hand, with the degree of extension and thematic development of this paper, the objectives set out in Section 1 have also been fulfilled, in order to make an inventory of the main aspects not included in ISO 50001:2018, and of the critical needs of organizations that implement the comprehensive management systems CMS QHSE3+, of having a simple, holistic fusion/integration route, in harmony with the nature of each business and its target markets, based on a conceptual model that can be implemented through a project in which the deliverables contribute effectively towards the sustainable success of the entrepreneurial efforts.
With this purpose, it is emphasized that it is precisely management that gives a comprehensive character to the system. In addition, the system should not simply be a combination or addition of components, and should be fully aligned with the nature, purposes and strategic focus of the business, ensuring that in all cases energy efficiency management is included in the risk maps and the portfolio of strategic projects of each business, and that the "thought based on risks and opportunities" be part of the institutional culture and daily life of people.
It is precisely in this last point associated with the awareness and appropriation of the good practices QHSE3+, where we have the Achilles heel.
From this investigation, we have shown that a comprehensive management system with a QHSE3+ perspective can be applied in companies, with quite encouraging results in terms of vulnerability reductions ranging from 4.60% to 18.60% in a heterogeneous group of companies, or, with significant reductions in energy consumption, which can financially support continuity in projects to consolidate CMS.
On the other hand, SMEs continue to go bankrupt and do not exceed 5 years of life. Entrepreneurship efforts have a high percentage of failure, while energy wastage, global warming, excessive use of resources, and irrational consumerism remain constant and there are very few states with strong, mandatory, and punitive legal regulations on energy efficiency.
Against this background, from the community of consultants, teachers, entrepreneurs, workers, and researchers related to the CMS QHSE3+, we must continue to develop tools and strategies to promote the massification and widespread use of good practices for project management, energy efficiency, and comprehensive management for sustainable success with meaning.
