3.1. Recommendation 1: Expand the Knowledge Base
A broader range of reliable sources of knowledge and data is urgently required!
The integration of broader and more diverse sources of knowledge, experience, and data is essential for advancing scientific inquiry. In addition to traditional academic sources, valuable insights can be derived from fieldwork. This includes expert interviews, timely reports on innovations and technological developments (even those emerging from adjacent fields), and scholarly discussions. Many professionals with deep technical expertise, such as consultants, IT specialists, project managers, quality specialists, and corporate controllers, typically do not contribute to academic literature [
1].
Current academic conventions, however, lack the mechanisms to adequately capture and systematically document the expertise of these groups. As a result, integrating the actual developmental status of Industry 4.0 and 5.0 remains incomplete as their practical knowledge cannot be fully incorporated or effectively communicated within the prevailing scientific frameworks. For example, motion mining can evaluate and improve manual processes from a lean perspective [
2].
This gap places researchers in a challenging position. Non-academic, non-written knowledge is often excluded from formal documentation and referencing. In strict methodological terms, it may constitute an omission of relevant knowledge and a deviation from the principles of scientific integrity. These practitioners, however, are essential contributors to the development of optimal solutions. They possess in-depth understanding of infrastructural requirements, common operational pitfalls, and the economic limitations faced by enterprises, particularly small- and medium-sized enterprises (SMEs). They often find it difficult to absorb the fixed costs of digital transformation without jeopardizing their competitiveness.
Moreover, the inclusion of interdisciplinary perspectives has been shown to enhance the quality of solutions. Alongside conceptual research, expert dialogs and scholarly debates represent pivotal methods of knowledge acquisition. In this context, Trojahn et al. [
1] have identified key sources of scientific knowledge, which the authors regard as a transformative development in the technical sciences (see
Figure 1). The figure presents a framework illustrating how various sources contribute to the development of research questions, identification of gaps, and understanding of the current status in a given field. At the center is the researcher, surrounded by the following key input categories: scientific media analyses, practice inputs, inventions and innovations, relevant trends, expert surveys, own data, scientific discussions, and literature reviews. These diverse sources interact to inform and shape the research process, ensuring that it is grounded in both theoretical knowledge and practical relevance [
3].
A substantiated assessment of the current state of knowledge is essential for the further development of logistics systems.
Table 1 shows the key components of a holistic analysis that systematically incorporates different sources of information. These include scientific media, market analyses, expert interviews, and current research findings, as well as our own observations and operational data. The aim is to capture relevant knowledge in a structured way—from theoretical principles and practical applications to real-world metrics and trends—to provide a reliable basis for strategic decisions.
3.2. Recommendation 2: Implemenation and Manual Processes!
Two distinct solutions are required: one for standard cases and another for exceptional scenarios where no digitalization is available.
In the era of digitalization and ubiquitous networking, manual processes continue to play a significant role. Certain processes inherently favor manual execution, including the following:
Unique or unpredicted processes,
Critical processes,
Novel processes requiring initial testing prior to automation,
Processes mandated by legal or regulatory frameworks to involve manual intervention,
Inventive processes that derive value from human ingenuity (see more in [
1]).
These scenarios demand not only the continued use but also the potential development of manual process variants. Moreover, the process landscape extends beyond a simple dichotomy of manual versus digital operations. Manual processes are often highly flexible manufacturing processes. Digital assistance systems make sense. These use a wide variety of sensor technology [
4]. Hybrid approaches frequently deliver superior outcomes—for example, integrating FAQs, chatbots, and human interaction to enhance the quality of customer information services (see
Table 2).
Additionally, the rising frequency of disruptions affecting digital solutions cannot be overlooked. Notable examples include the following:
Unauthorized publication of sensitive data,
Disruption of administrative systems through cyberattacks,
Incidents involving data manipulation,
Power or Internet outages (e.g., the case of Cuba, Spain).
Not only do such events enflame fear and a heightened sense of vulnerability, but they also force decision-makers to take significant action. Guaranteeing the resilience of digital solutions requires flexibility, such as the integration of redundancy, alongside agility for swift responses in times of disruption.
These scenarios underscore the urgent need for robust solutions that complement conventional digital processes. Both industrialized and developing nations stand to benefit from mutual learning and collaboration in developing intelligent offline solutions. But is universal digitalization truly necessary? Not in all cases. When thinking about cost-effectiveness, how often a process repeats, its importance, and what we have learned from experience, it becomes clear that not every process should be digitalized without careful consideration.
Figure 2 presents a decision-making framework to guide throw this process.
In addition, the effects of switching to digital processes can be taken into account when making decisions. Digital processes significantly reduce time- and cost-intensive factors such as working time, susceptibility to errors, resource consumption, and the rework process. At the same time, the use of digital solutions noticeably increases key performance indicators such as speed, efficiency, scalability, and competitiveness. Digital tools can simplify and speed up manual processes [
5]. Manual workstations continue to play an important role. AI-supported assistance systems are necessary [
6].
Digital processes are especially appropriate for the following:
Standardized and routine processes,
Processes requiring statistical analysis,
Processes historically plagued by high error rates and extensive processing work,
Complex processes with many participants.
Manual processes are especially appropriate for the following:
Sporadic and flexible processes,
Processes with a need for human interaction,
Ethical processes.
Manual processes act as a safety net for high-risks processes, tasks with small failure tolerance, and newly implemented processes. They offer a fallback option, ensuring continuity in situations characterized by high risk or inherent unpredictability.
3.3. Recommendation 3: Remove Difficulties
High costs, a lack of qualified employees, and security concerns delay the widespread digitalization and networking efforts in SMEs!
Table 3 presents our step-by-step approach designed to address obstacles to digitalization within the research process. This visual representation clarifies the sequential method used to identify and overcome barriers, thereby aiding in a smoother transition to digital solutions.
Table 3 outlines a structured process for addressing digitalization barriers across various sectors such as production, logistics, trade, and agriculture. It begins with the identification of barriers (Step 1) and progresses to defining measures aimed at mitigating these barriers (Step 2). The process continues with the selection and alignment of relevant literature for scientific referencing (Step 3), culminating in the compilation of findings into an actionable guideline (Step 4).
Building on the identification of barriers and strategies,
Table 4 presents specific obstacles in digitalization along with measures to overcome them.
In strategy and leadership, common issues include the lack of a digitization strategy and undefined goals. Organizations are advised to outline clear objectives, create precise plans, and prioritize projects, especially when resources are tight. Data protection and security are major challenges due to high requirements. Measures include appointing a data protection officer, providing regular employee training, and conducting external audits to ensure compliance with security standards. Costs pose significant barriers, with high initial investments and maintenance expenses. Recommendations include identifying funding programs, focusing on ROI, and exploring open-source software for cost-effective solutions. Human resource challenges, such as a lack of skilled personnel and technological know-how, are addressed by encouraging regular training, collaborating with universities, and involving employees early in digital initiatives. Poor internet connectivity is highlighted as an infrastructure issue. The table suggests modernizing IT infrastructure and using cloud technologies to support digital operations more effectively.
The previous tables have provided a detailed look at the specific barriers to digitalization and offered actionable measures to address them. Building on this foundation, the next table compiles insights from extensive literature reviews and expert interviews to reveal common obstacles across various studies. This literature-based analysis enhances our understanding of systemic challenges and underscores the need for comprehensive strategies to overcome them.
The following
Table 5 offers a synthesis of key obstacles identified in the literature, ranging from IT security and data protection to the lack of qualified personnel and digital infrastructure. It highlights recurring themes such as high administrative burdens, uncertain economic benefits, and legal uncertainties.
By presenting these insights, the table emphasizes the importance of addressing both technological and organizational hurdles in digitalization efforts. It serves as a valuable reference, guiding future research and practical implementations aimed at overcoming these persistent challenges.
The following obstacles are consistently observed in both our own analyses and the findings from the literature:
Budget constraints,
Data security,
Shortage of staff.
Table 6,
Table 7 and
Table 8 show examples of how to promote digitalization processes in companies.
Table 6 shows various internal measures to reduce fixed costs in the context of digitization. It clearly demonstrates how fixed costs can be reduced through targeted technological and organizational approaches and how digitalization can be designed to be economical.
Table 7 provides an overview of the most important measures that can be taken to improve data security within the organization. Both internal technical and organizational approaches as well as external audits and collaborations are presented. The measures range from data encryption and security guidelines to penetration tests and cooperation with external security experts.
Table 8 shows an overview of key measures for recruiting, retaining, and developing qualified personnel both within the company and through external partnerships. In addition to strategies such as attractive employer branding, flexible working models and targeted personnel development, partnerships with educational institutions, external consultants, and innovative recruitment approaches also play an important role.
In contrast to the past, the focus should not only be on one-off training, but on regular training and testing at the latest level. The organization of basic and advanced training for first responders, for example, serves as a model, renewing, expanding, and regularly training knowledge and skills through refresher courses and training sessions.
As online and self-learning will become more important in the future, this area must also be actively developed with digitalization. A company will only be successful in the long term if it keeps its own staff up to date and trained.
Table 9 lists some important formats in the relevant area of further education and training and at the same time offers scope for your own additions and activities in the future. The aim here is not to be exhaustive, but to provide suggestions for diversifying this area.
