4.1. Literature Query
Implementation of the purpose of the study and verification of theses required - first of all - procuring a catalog of benefits that significantly identify the research model. The first research technique that was chosen to collect primary data focused on its development was the reconstruction and interpretation of the literature on the subject. Such action - in the design dimension - made it possible to compile a general catalog of parameters constituting the basis for the design of the research tool in the form of an assessment questionnaire. The conducted analyzes clearly indicate the dissemination of the concept of maturity. In the context of the query, it was established that the number of publications citing previously published works is systematically increasing. The above allows us to conclude that for the construction and analysis of solutions published on an ongoing basis, publications appearing in the WOS or Scopus databases are used, but also those that, due to various conditions (such as national languages, the range of the journal), were not included in these databases.
Therefore, it was decided to extend the process of creating the literature database with the so-called gray literature. This was considered important in order to include recent scientific publications as well as publications of a less scientific nature. The literature review (Green, 2005) was carried out in three stages, starting from: (1) creating a literature database, through (2) selection of works included in further analysis, and ending with (3) critical content analysis [
5]. Taking into account the perceptual and time capabilities of the authors, as well as the existing limitations in practice, it was decided that publications that most significantly reflect the definition problem in question would be included in the final database.
Literature reconnaissance allowed not only for a formalized and objectivized synthesis of the hitherto scientific achievements or the assessment of research conducted so far [
6,
7,
8,
9,
10,
11,
12], but above all, it enabled the identification of areas both explored and unexplored [
13,
14,
15,
16,
17,
18,
19]. This gave rise to defining the framework for further research [
20], the results of which may form the basis of subsequent exploratory work [
20].
Accelerated obsolescence of some theories (caused by the volatility of the conditions of their application) causes great difficulties in verifying their scientificity, and thus distinguishing real, true concepts and methods from fashions and quasi-scientific products functioning on the market. Another problem is the time dissonance between the expectations of the practice and the offer of science in the form of indications and concepts of the functioning and development of the organization in postmodern conditions. In fact, there is a certain confusion around the concept of sustainable manufacturing, which is caused by the following factors:
multiplicity of ways of interpreting this term;
the occurrence of synonymous terms, such as: stability or durability;
defining sustainable production through metaphors (epistemological pluralism);
considering sustainable generation through the prism of specific parameters;
interdisciplinarity of sciences (different research trends influence them);
transferring scientific achievements from other countries or sciences without clearly indicating the origin and meaning of the discussed terms.
However, theory and practice show that it is far from adopting a single, universally accepted definition [
22]. Despite many attempts to reconcile positions among researchers, there is no unequivocal agreement on the meaning of the concept itself. It seems that this is not a defect or limitation in the practical application of this concept. This is rather a pragmatic attitude in which definitional usefulness is more important than theoretical construction.
In the study, the authors abandon the search for a single, common and universal definition. In their opinion, it would neither enrich the knowledge nor practice of management, and at the same time could lead to distortion of the research field. Although the only proper way to practice science is the multiplicity of ways of seeing, interpreting and shaping the examined part of reality, the conducted analyzes clearly indicate that the concept of sustainable production expresses a holistic approach to business, while postulating reduction and elimination of all losses. It defines a set of rules and techniques aimed at maximally economical organization of the enterprise and the production process. A manifestation of this is the introduction of changes in the organization and technology of production, sales, internal and external logistics processes, bringing reduction of incurred - nothing justified - costs. A sustainable company therefore takes into account many aspects of organizational activity and at the same time is not limited to establishing a rigid framework of areas that can be subjected to process analysis. It takes into account the perspective of employees (well-being), companies and environmental issues. The indicated planes are considered fundamental as part of a comprehensive assessment of this concept.
Assuming the premises of creating unconventional business management instruments, especially in the era of the fifth industrial revolution, it seems completely reasonable to implement the concept that takes into account ecological dimensions at the early design stage, when the necessary materials, production technology, life cycle and durability of the product are defined [
23,
24,
25]. A holistic approach to design, taking into account, in addition to traditional design, also environmental elements, allows you to combine customer needs with the company's responsibility for the environment [
26,
27] and as such should determine the level of sustainability of the organization [
28]. A sustainable company focuses on identifying environmental aspects.
Similarly, activities to increase the well-being of employees arouse great interest, especially among management practitioners, due to the benefits that the company achieves in humanistic and economic terms (research in this area is conducted by, among others: [
29]. Although sometimes these are initiatives focused on the implementation of single rather than comprehensive solutions, they are increasingly associated with strengthening the organizational culture [
30,
31]. The literature studies conducted in this area allowed to gather evidence of such a relationship [
32,
33,
34,
35,
36]. The well-being of employees contributes to greater employee satisfaction and improvement of interpersonal relations, on the one hand, and, on the other hand, reduces stress, professional burnout or deterioration of mental health. The above is reflected in the research presented by the authors of the study.
To sum up, it should be clarified that well-being in the spirit of humanism consists primarily in: (1) unconditional respect for dignity, individuality and protection against exploitation of every human being (employee); (2) ethical reflection on the universal value of good, which is an integral part of business decisions; (3) the implementation of this ethical reflection into the actual conduct of the organization in the spirit of reconciling intentions with actions. It is worth noting that only recently has it been understood that life has a deeper value, and technical ordering and market optics should be treated as methods of achieving goals by organizations, not goals in themselves.
The development of the organization expected in the key vision of aspirations and mission defining the ideas of its operation is precisely conditioned by the development and argumentation of its employees. From the perspective of balance in management, this forces an evolution in the culture and cleaning behaviors initiated in the processes of shaping and communicating changes in the organization's policy, communicating their effects, methods of job evaluation, systems of evaluation, remuneration and employee development. An instrument supporting the determination of the scope of the indicated changes and modifications is a systemic analysis of the problem of the implementation of the motivational function in the sustainable management of the company.
Positive attitude combined with motivation for achievements, sacrifices and sacrifices causes employees of the organization to focus on the content of work, which increases the sustainable sustainability of the company. Attitudes result in specific behaviours, values and cultural norms. They are the core of the working environment, whose external image is the behavior of employees, for whom employers should provide an appropriate level of motivation. The point is to use their potential as much as possible. Hence, the voice of the employee is more and more often appreciated. He is treated with due respect as an expert in a specific field. It is the best and most reliable source of knowledge about a given process or technology.
The material collected - as part of the literature search - enabled the formulation of conclusions of a general and cognitive nature:
the activity of owners and managers of enterprises is increasing, which manifests itself in the pursuit of efficiency and rationality of management;
the level of sustainability of the enterprise changes over time as a result of changes in the enterprise itself (self-acting and those resulting from intentional management activities) and market and macro-environment impacts independent of it;
a sustainable enterprise is one that demonstrates long-term development ability and good economic, relational and environmental condition that persists despite changes in external conditions;
a sustainable company is able to define the configuration direction of its resources in response to the impact of both internal and external factors in order to adjust to the market;
the well-being of employees is a codified dimension in the area of sustainable production, oriented directly to increasing the efficiency and effectiveness of the actions taken. In this sense, it is expressed through the ability of enterprises to meet the requirements of the market.
Although it has been shown that the panacea for the sustainable and sustainable functioning of the company should be the resources, abilities and competences at its disposal, a thorough query of the research directions proposed in the literature, it was clearly stated that no research was undertaken on the well-being of employees from the perspective of the concept of sustainable production emphasizing benefits and effects achieved by companies producing parts and subassemblies of technical means of agricultural transport. Thus, it was confirmed that there is a deficit of knowledge in this area.
4.3. Conclusive Research
The survey (June-August 2023) was attended by 63 respondents (representatives of companies manufacturing subassemblies and technical parts of means of agricultural transport. The surveyed enterprises included producers of products classified within groups [
37]: (1) agricultural tractors [
38], (2) cars and trailers [
39], (3) self-propelled machines, e.g., harvester for harvesting potatoes, harvesters for harvesting species of fruit plants and vegetables [
40].
For the purposes of collecting statistical material, a properly designed questionnaire was prepared, and the data collection process itself was carried out using the CASI technique.
The vast majority of the surveyed enterprises had only Polish capital (74.60%), 19.05% had mixed capital, and only 6.35% had only foreign capital. Most of the surveyed entities were natural persons conducting business activity (58.73%). The share of enterprises operating in the form of a limited liability company was also relatively high. (25.40%) and civilian (7.94%). On the other hand, the share of joint-stock companies (1.59%) and public companies (6.35%) was insignificant. Most of the companies that took part in the survey were companies with 10-50 employees. Their share in the research sample was 46.03%. The percentage of companies employing 51-250 employees was also high (36.51%). The share of small companies (up to 9 employees) was 11.11%, and large ones (over 250 employees) only 6.35%. The vast majority of enterprises have an established position on the market and have been operating on it for many years. It can be seen that there are 63.49% of companies that have been operating on the market for at least 11 years. The percentage of companies operating on the market for 6-10 years is also quite high (26.98%). On the other hand, companies that have been operating on the market for at most 5 years, a total of 9.52% participated in the survey. Most of the surveyed companies run their business on the domestic (42.86%) and European (36.51%) markets. The share of enterprises in the agricultural machinery sector (technical means of agricultural transport) operating globally amounted to 20.63%. The products manufactured by the company are 30.16% original parts, which are mainly used on the so-called first assembly (OE - Original Equipment). In the case of 23.81% of enterprises, products are manufactured on the same production line as spare parts; they are not marked with the logo of the manufacturer of the agricultural means of transport, but with the logo of the parts manufacturer (OEM - Original Equipment Manufacturer). As many as 28.57% are companies whose parts have appropriate certificates but are not delivered for the first assembly (OEQ). For 17.46% of companies, substitutes that do not have certificates are crucial.
The vast majority of the survey was filled in by people holding positions at the highest management level of the company. Most often they were owners and co-owners (46.03%) or persons from the management board of the enterprise (22.22%). The percentage of people from the company's senior management (14.29%), middle management - 9.52% and those holding lower positions in the company (7.94%) was much smaller. The vast majority of respondents (44.44%) who represented enterprises in the process of completing the questionnaire had a master's degree. It is worth emphasizing that a separate (relatively numerous) category consisted of people with not only higher education, but also post-graduate studies (14.29%). The share of people with higher education - bachelor's degree (12.70%) was also visible. On the other hand, there were only 28.57% of respondents who had lower than higher education (vocational and secondary education, with the majority of people with secondary education in this group). The majority of respondents filling in the questionnaire were people aged 45-54 (34.92%). The share of people aged 36-44 (26.98%) and 55-65 (22.22%) was also significant. Younger people, i.e., not older than 35, accounted for only 4.76% of all respondents, and those aged 65+ as much as 11.11%. The respondents were characterized by a very large experience in working in the sector, as 58.73% have more than 15 years of work experience in this industry. The share of people (in total 33.33%) was also significant, for whom the work experience in the sector of technical means of agricultural transport was in the range of 6-15 years. People with little experience (less than 5 years) accounted for only 7.94% of all respondents.
4.4. Conclusive Research
In this part of the study, an attempt was made to verify the theoretical - and resulting from expert research - assumptions about the type of specific benefits that, as a result of implementing the concept of sustainable production (taken from the perspective of the well-being of employees), are achieved by manufacturers of parts and technical subassemblies of agricultural means of transport. This verification is preceded by a thorough analysis of the literature and indications of the so-called competent judges, whose suggestions and recommendations were reflected in the form of a research tool.
Evaluation of the benefits resulting from the implementation of the concept of sustainable management is quite difficult, however, the study attempts to carry it out. Although this concept is one of the key factors determining the organization's competitive advantage, the issue of evaluation of partial activities is increasingly on the agenda of the debate on the manifestations of its effective implementation.
The concept of sustainable production (which in this case is identified with the well-being of employees) consists of specific partial dependencies. These relationships are recursive in nature, as it is difficult to talk about global effects without referring to the elements that structure these effects. As in the case of the relationship between the organization and its components, there is a synergistic effect that makes the concept of sustainable production something more than a simple arithmetic sum of partial benefits obtained.
To recapitulate, sustainable production may concern various areas related to the functioning of the enterprise: the use of machines, work, material flows, product offer, operational activity, development, size of operation, assortment portfolio, introducing new (modifying) products.
Therefore, the processes implemented in the company can be the subject of reference. Taking into account the division of processes into organizational and management. With reference to the above - as part of the organizational and management processes - the analysis of benefits was carried out highlighting twelve parameters. The test results are shown in
Table 2.
First, basic descriptive statistics were determined for all analyzed factors (benefits) (respondents rated them on a five-point Likert scale, where 1 meant a definitely small benefit and 5 definitely significant).
Table 2 presents the arithmetic mean values in the order of the considered factors. It can be seen that, regardless of the potential benefit, there were extreme ratings (1 and 5), and most often the determinants were rated at 4 (significant). In the case of nine factors, the average respondents' assessment of their importance is above 4 (rather important). A similar analysis regarding the degree of potential benefits was carried out taking into account the legal form, size of employment, age, seniority in the industry and company. At the same time, it was limited to providing the average values of the ratings. When analyzing the presented averages, it can be seen that the legal form, size of employment, age of the respondent, seniority in the industry and seniority in the current company do not significantly differentiate the assessment in the surveyed enterprises. In fact, in most of the components analyzed and relating to the benefits resulting from the implementation of the concept of sustainable production, the differences between the averages did not occur or were only at a low level.
Appropriate work culture, defining proper relations between the management and contractors of production tasks, determines the effectiveness of work teams, and they determine, among others, pace and type of actions aimed at obtaining a proper working environment that gives a sense of security (4.25). This requires the development of cultural values based on knowledge, reliability, qualifications and ethics - functioning in the space of the company - employees. The conditions in which all employees see the need to join in activities for the implementation of changes taking place in their enterprises have been indicated. Their activation and openness to new ideas and improvements in the way of working are visible (4.19).
A successful transformation towards a sustainable enterprise focuses on technical changes aimed at building technical stability of processes, implementing a rapid flow of value and technical improvement and improvement of procurement processes. Attention was drawn to the increase in trust and cooperation with suppliers (4.06). Procurement takes on a proactive character, it sets the network of connections and the direction of managing the networks and the processes taking place in them. Therefore, mutual use of links with suppliers is indicated. Cooperation with suppliers participating in the development of products is a source of innovative ideas, new technologies and unique solutions for enterprises.
With the support of leaders, employees know how to take full responsibility for their actions and tasks (4.14) and how to rely on themselves, they are focused on achieving valuable goals. The role of managers is evolving towards helping people do their best work and anticipating and eliminating constraints that hold back collaboration. Where there used to be constraints, competition and distrust, companies have introduced teamwork and collaboration (4,13). The elimination of barriers related to the time of order fulfillment, timeliness of deliveries or efficiency of administrative activities is indicated.
As all factors that affect the quality of the designed products should be taken into account from the beginning of their creation, i.e., from the design stage through production, attention was paid to taking into account customer expectations, referred to as voice of customer, and transferring them to product features expressed as counterpart characteristics. In the context of meeting customer requirements by designing the process and production systems, attention is paid to the development of the quality function. The company takes into account the voice of the customer and is sure that it has been transformed into the right strategy and product. The above translates into improved product quality (4.02).
In the context of the research defined within the "Technology and production layer" group, nine factors were identified. The test results are presented in
Table 3.
In the case of eight factors, the average respondents' assessment of their importance is above 4 (significant benefits). Although the analysis regarding the degree of potential benefits was carried out taking into account the legal form, employment size, age, seniority in the industry and company, these characteristics do not significantly differentiate the assessment in the surveyed enterprises. The presentation of the research results was limited to giving the average values of the ratings. In fact, in most of the components analyzed and relating to the benefits resulting from the implementation of the concept of sustainable production, the differences between the averages did not occur or were only at a low level.
Among the surveyed enterprises, the use of the created, e.g., by standardizing work (4.00) the basis for determining waste in the process and improving the process by eliminating identified activities that do not bring value (4.30). A technical culture is achieved, which implies minimizing losses in the entire production process. Reducing inventories, ensuring the optimal level of energy consumption, minimizing waste production or minimizing production costs and other operating costs increase the efficiency of production and allow for safe and sustainable operation of enterprises. Companies also declare real profits in terms of minimizing the length of the production cycle (4.16) and improving the production index based on current demand (4.11). Another circumstance confirming the legitimacy of the implementation of sustainable production is the pre-orientation of a set of techniques and tools enabling a faster response to emerging problems (4.08), shortening the changeover times of machines, devices and production processes (4.06) and self-control allowing to identify typical sources of errors, which - at a later stage - it allows you to take appropriate countermeasures (4.05). This allows for production security, enables quick implementation of corrective actions and rapid adaptation to changing requirements. The realization of the existing benefits are also actions undertaken by employees to improve their workstations and the production technologies used (4.03). A properly configured production system delivers products in line with customers' expectations, i.e., of the highest possible quality, at the right place and time, and most importantly, at the lowest possible cost. This possibility depends directly on the people who create, implement and supervise the system, and on the contractors who participate in the implementation process throughout the product life cycle, focusing on their flow (4.00).
Within the research defined in the third group, nine factors were distinguished. The results are presented in
Table 4.
In the context of all identified and analyzed benefits, the average rating of the respondents regarding their essence is above 4 (significant benefits). Although the analysis was carried out taking into account the legal form, size of employment, age, seniority in the industry and company, also in this case these characteristics do not differentiate the assessment in the surveyed enterprises. Therefore, presenting the results of the research was limited to providing the average values of the ratings for individual parameters. Similarly, in most of the components analyzed and relating to the benefits resulting from the implementation of the concept of sustainable production, the differences between the averages did not occur or were only at a low level.
In the context of the conducted research, it is noted that employees perform their work very well, have the appropriate knowledge and skills and are able to use them properly in changing situations. Attention is drawn to their involvement in the process of improving and raising competences (4.25). Professional competences are defined by high expectations regarding knowledge, skills, attitudes, abilities and predispositions, which are reflected in a large number of innovations proposed by them (4.27). The surveyed entrepreneurs are aware of the fact that a proper training policy allows for a conscious and deliberate influence on the knowledge, behavior and attitudes of employees, which they implement hereby, in accordance with the assumption of the concept of sustainable production and the related well-being of employees. The added value is the motives of knowledge-sharing behavior (4,13). Operating in a competitive environment, the surveyed enterprises improve their processes. The tool that encourages employees to improve is the employee idea program, which implies the possibility of freedom of action for active employees who want to implement creative ideas, which affects the matching of contractors to the level of tasks performed (4.19) and a constant increase in job satisfaction (4.17). Attention is drawn to the possibility of submitting innovative ideas without fear of disregard (4.05), which results from the organizational culture adopted and pushed by the management board.
The conducted evaluation was an excellent opportunity to exchange knowledge and experience regarding cooperation with scientific units. The research results confirmed the authors' belief that the cooperation of universities and technology parks with enterprises, which is essential for the creation and development of innovations based on scientific ideas, has an upward trend. Although some entrepreneurs in the activities of technology parks and universities see the threat of reducing the role and participation of the company in transforming the results of scientific research into technological innovations, they recognize the need for cooperation within the implemented concept.
