From Industry 4.0 towards Industry 5.0: A Review and Analysis of Paradigm Shift for the People, Organization and Technology

: The industry is a key driver of economic development. However, changes caused by introduction of modern technologies, and increasing complexity of products and production, directly affect the industrial enterprises and workers. The critics of the Industry 4.0 paradigm emphasized its orientation to new technologies and digitalization in a technocratic way. Therefore, the new industrial paradigm Industry 5.0 appeared very soon and automatically triggered a debate about the role of, and reasons for applying, the new paradigm. Industry 5.0 is complementing the existing Industry 4.0 paradigm with the orientation to the worker who has an important role in the production process, and that role has been emphasized during the COVID-19 pandemic. In this research, there is a brief discussion on main drivers and enablers for introduction of these new paradigms, then a literature-based analysis is carried out to highlight the differences between two paradigms from three important aspects—people, organization, and technology. The conclusion emphasizes the main features and concerns regarding the movement towards Industry 5.0, and the general conclusion is that there is a signiﬁcant change of the main research aims from sustainability towards human-centricity. At the end, the analysis of maturity models that evaluates enterprises’ readiness to introduce features of new paradigms is given as well.


Introduction
In the last decade, we have been witnesses of transformations inside production systems, especially in the field of digitalization [1].Information and communication technologies (ICT) are involved in every step of production [2].This causes the various complexities in several aspects: technological, logistical, organizational, and environmental.A complex transformation process is taking place that needs to be effectively managed.The application of new technologies has significant impact on people at work and in everyday life [3].People are involved in the process of transforming industrial paradigms, whether they work as workers in the industry or as customers that require a specific product from the industry [4].As important participants, both workers and customers need to be flexible in adapting to new working conditions and open to learning and sharing knowledge [5].Another important segment in industry affected by paradigm transformations is organization.Today, the organization is characterized by decentralization, where the decision-making process has been delegated by top managers to workers who are lower-level managers and sometimes to blue-collar workers [6].The idea behind the decentralization is to quicken the decision-making process by those who have the most information and ability to react in real time.However, to support this idea, the application of new technologies and digitalization is crucial.The data collection and processing bring the proper information [7] so the worker can react fast.A new industrial paradigm, Industry 5.0, appeared very soon after Industry 4.0 and triggered a debate about the role of, and reasons for, applying the new paradigm.The Industry 4.0 is based on the concept of smart factory, where smart products, machines, storage systems, and data unite in the form of the cyber-physical production systems [8,9].In the technical aspect, Industry 4.0 has improved the human-machine interaction, but in the socially sustainable aspect, technological transformations of Industry 4.0 should carefully consider the central role of humans [10].The role and importance of employees was emphasized during the COVID-19 pandemic, and the pandemic itself triggered rethinking of the Industry 4.0 paradigm [11,12].Consequently, the idea of Industry 5.0 appeared as the extension to Industry 4.0 with social and environmental dimension [13].On the one side, Industry 5.0 is focused on the workers' skills, knowledge, and abilities to cooperate with machines and robots [14,15], and on the other side, on flexibilities in production processes and environmental impact.
The obstacles to introduce Industry 4.0, arising from technological and organizational points of view, lead to rethinking the process about the shortcomings of the Industry 4.0 approach.Several drivers encourage thinking and discussion about the new paradigm.One of the important drivers is personalized product, where customers participate in product design and production for adaptation of the product to their own needs [16,17].Other drivers originate from the inability of the SMEs (small and medium enterprises) to implement the Industry 4.0 approach [18,19].There are lot of studies in the context of Industry 4.0 for SMEs, which are pillars of the economy in many countries because of their contribution to gross domestic product (GDP).The new technologies require high investments and knowledge of how to use them and integrate in existing environments to achieve the best results in production [20].The important question is: Which technologies should the enterprise use to achieve the best results [21]?This opens the question about the assessment of readiness for changes [22][23][24].Whatever question is opened, it is always necessary to start with the key enablers of production.This is where the rethinking process is justified with the aim of highlighting the human-centric perspective.
The topics from this article hold a crucial place in each branch of industry.The purpose of this paper is to discuss the main connections between the basic driving concepts of Industry 4.0 and Industry 5.0, but also to emphasize the key enablers: people, organization, and technology, in theoretical and practical context.The key enablers are intensively studied for the last decade in the context of industry progress.The intention of this work is to achieve better understanding of the appearance of Industry 5.0, referring to the key publications which are cited to highlight the directions of research in this field.As a reminder of past trends, Figure 1 shows the transformations through the paradigms according to the important participants and segments of industries.Additionally, better understanding of the appearance of Industry 5.0 represents the base to rethink real industry processes and possibilities to apply appropriate concepts that best suit specific challenges that industry faces, to achieve the best results in each aspect: people, organization, or technology.
The rest of the paper is organized as follows.Section 2 emphasizes basic driving concepts for each paradigm and the flow of the scientific papers collection.Section 3 introduces the review of existing literature, summarizes main transformations to move towards each paradigm, and represents the connection between key enablers and people, organization, and technology in a practical context.Section 4 discusses the importance of represented connections in Section 3 and readiness to introduce any features of new paradigms.Section 5 gives the concluding remarks.[25] and to learn by doing.There are important key drivers [26,27]:

•
Internet of Things, services and data that enable the communication between objects.By placing the intelligence into objects, they are turned into smart objects able not only to collect information from the environment and interact or control the physical world, but also to be interconnected to each other through Internet, to exchange data and information [28][29][30].

•
Human-centric approach, which places human needs at the heart of the production process, asking what technology can do for workers and how can it be useful.

•
Sustainability, which focuses on reuse, repurpose, and recycle of natural resources and reduce of waste and environmental impact.

•
Resilience, which implies an introduction of robustness in industrial production.This robustness provides support through flexible processes and adaptable production capacities, especially when a crisis occurs.

[41] are interpreting According to the European Commission, Industry 5.0 is a necessary evolutionary step of Industry 4.0 because of following important issues [40]: • Industry 4.0 is not the right framework to achieve Europe's 2030 goals, because the current digital economy is a winner-takes-all model that creates technological monopoly and giant wealth inequality.

[44] are investigating perspectives of people, process, performance, and technology in the Industry 4.0 food supply chain.Kiepas [45] is, similar to Oks et al. [46], simplifying the focus on key enablers, narrowing them to the three most important: humans (people), organization, and technology.
Therefore, a search was carried out within the Scopus database to explore papers related to Industry 4.0/5.0 and three most important enablers: people, organization, and technology (Figure 3).The literature reviews and state-of-the-art papers were excluded from the search.Industry 4.0 future within technology, business, society, and people.Similarly, Sony and Naik [42] are investigating the integration of Industry 4.0 with people, infrastructure, technology, processes, culture, and goals.Akcay Kasapoglu [43] is focused on the aspect of leadership and organization during the process of Industry 4.0 transformation.Kayikci et al.

Currently, there are many useful studies about the new technologies characteristic for Industry 4.0, its introduction, and benefits [27].The studies that emerged from the literature seek a clear vision of how Industry 4.0 impacts business models and organizations [50,51].However, it is stated how smaller efforts have been devoted to the role of humans in the future factory, the appropriate organizational models, the approaches for long-term value creation, and the outcomes on society [52].These linked aspects in terms of technology, people, their employability, and sustainability-related issues are crucial for long-term improvement.

Review of Key Enablers in
Figure 5 summarizes the literature review on Industry 4.0 in relation to people, organization, and technology.The research topics of each enabler were identified and their distribution is presented.Furthermore, the main research aims of analyzed papers were identified in correlation with drivers of Industry 5.0: human-centricity, sustainability, and resilience (Figure 5a).
The same summarization of the literature review on Industry 5.0 is presented in Figure 6.The most interesting fact is a switch in research aims.The sustainability was a major research aim in Industry 4.0, but in Industry 5.0 the human-centricity becomes a major research aim.As already mentioned, the lack of human perspective was a major disadvantage of Industry 4.0 and its main critic [39].Another interesting fact is the rise of ethical research, with a significant share of research on ethical business and on ethical technology, as well.It is also connected with human-centricity and sustainability of Industry 5.0.
Regarding technology, Industry 4.0 was oriented to every emerging technology.However, with Industry 5.0, some of the emerging technologies are receiving more research focus, and research interest for some others is declining.This change in trends is presented in Figure 7. Again, rise of interest for human-machine interaction and artificial intelligence shows that more focus is being placed on use of technology as a support to the everyday tasks of the human worker.The Industrial Internet of Things has become a major technology research topic, because the 5G cellular network has become a standard nowadays.Currently, there are many useful studies about the new technologies characteristic for Industry 4.0, its introduction, and benefits [27].The studies that emerged from the literature seek a clear vision of how Industry 4.0 impacts business models and organizations [50,51].However, it is stated how smaller efforts have been devoted to the role of humans in the future factory, the appropriate organizational models, the approaches for long-term value creation, and the outcomes on society [52].These linked aspects in terms of technology, people, their employability, and sustainability-related issues are crucial for long-term improvement.

Towards Human-Centricity
In the context of transformation towards Industry 4.0, in the literature exists the awareness that skills, knowledge, and abilities of people are important in the CPS.Operator 4.0 appeared as the operator of the future.The vision of Operator 4.0 aims to create trusting and interaction-based relationships between humans and machines [53].The ideal type of the factory worker of the future is participative and proactive [54].There is still a lack of understanding of the interplay between humans and technology [55].Even though Industry 4.0 was directed to the workers with disabilities (Figure 5), there was not enough adaptation of technology to people.On the one side, people need enough space to develop their skills and use their own creativity, and on the other side, they need technology only as an aid for harmonious collaboration, not to replace their work.This emphasize on human-centricity is now directed towards all workers (Figure 6), not only towards people with disabilities.Operator 5.0 should collaborate with the equipment by using its own physical, sensorial, and cognitive capabilities in an environment that provides safe work and technological assistance in the segments of work that are necessary for the operator, while technologies provide real-time information for making timely decisions.
The limitations for decision-making originate from lack of information, necessary for people for decision-making, which has changed now that the Internet of Things exists.At the moment, there are new technologies and algorithms able to collect huge amounts of data and sort and filter them, in order to use them for decision-making [56][57][58].
The development of modern tools in ergonomics with the help of Industry 4.0 technologies is becoming of more and more interest in many studies.The International Ergonomics Association offers three main domains of ergonomics: physical ergonomics (working postures, repetitive movements, material handling, safety, and health), cognitive ergonomics (mental workload, decision-making, skilled performances, motor response, trainings, and human-computer interactions), and organizational ergonomics (organizational structures, design of working times, processes, communication, and cooperative work) [59].The main domains of ergonomics [60]: • Physical domain-the Industry 4.0 technologies help with the automatization of manual repetitive tasks or hard-muscular tasks [61]; the devices to use on workplace are improving ergonomic feedback and new digital technologies improve internal logistics and transportation [62].

•
Cognitive domain-the Industry 4.0 technologies help through virtual models to improve perception and create timely interactions; augmented reality devices contribute to the reduction of mental workload [63]; data sharing is improving cognitive ergonomics.

•
Organizational domain-Industry 4.0 provides hybrid production systems to bridge the gap between humans and machines, which affects work organization and requires future skill development.
Digitalization, as a new direction in ergonomics, aims to improve working conditions and the quality of workplaces.The systems to support ergonomics should immediately inform workers about new conditions that appear and about their influence on workers in accordance with analyses that clearly point out requirements for organizationally-technical changes [64].Other challenges can be found in the studies about the assessment and optimization of postural stress and physical fatigue to identify critical factors and to optimize the assembly operations and workload capabilities at early design stages [65].The development of technology, namely, in terms of better adaptation to human needs, is oriented towards the following [66]:

•
Networked sensors with low-level intelligence that, at the same time, reduce network overload while allowing exchange of important data.

•
Creation of the digital twins, which provides monitoring of production and predicting possible scenarios [67].

•
Virtual training for workers to avoid possible dangerous situations while learning specific tasks, for example, in critical review for trainings in construction safety [68], numerous VR/AR systems were proven as efficient, usable, and applicable for training and education; however, there are some challenges to deal with for improvement.

•
Artificial intelligence, which enables the learning process for different machines or robots, so they are able to learn from humans and perform tasks based on this knowledge [34,69].
Special attention should be paid to the interaction between humans and robots, machines, or any other elements of the system.There are efforts in the literature to create frameworks for evaluation of the human and robot collaboration.In [70], five dimensions from the aspect of human factor in human-robot collaboration are emphasized for the evaluation: workload, trust, robot morphology, physical ergonomics, and usability.The example of a framework where trajectory prediction serves to avoid potential collisions and plan recognition serves to boost the efficiency of collaboration is included in [71].The integration of the human-robot collaboration in assembly systems is shown in [72], but taking into consideration operations parameters such as waiting times, parallel activities, and functional delays.
By placing human beings back at the center of industrial production, aided by tools, for example, collaborative robots, Industry 5.0 not only gives consumers the products they want today, but gives workers jobs that are more meaningful than factory jobs have been in well over a century [73].New jobs are, among other things, aimed at programming, organizing and planning, training, and maintenance.It is clear that knowledge in data science, machine learning, and artificial intelligence is very useful for the future jobs.The fear of jobs disappearing when introducing new technologies is justified because there are situations where automatization of processes with machines or robots can replace human work [74]; however, in the background there are many newly created jobs that enable the introduction of mentioned automatization process [75].To survive an increasingly competitive market, enterprises need people who are able to manage the changes and should be capable of moving from technology to solutions and from solutions to operations, which requires a broad skillset [76].Bridging the skills gap requires novel user-facing technologies-such as augmented reality (AR) and wearables-for human performance augmentation to improve efficiency and effectiveness of staff delivered through live guidance [77].
The human-centric approach is firmly attached to Lean management, i.e., its philosophy of the people's engagement in process improvement from shopfloor workers to managers [78].Lean, as a set of enterprise management tools, represents a strong support for organizing production, managing production, product development, and relationships with suppliers and consumers.To support the sustainable organization, there are studies where Lean management is supported by new technologies characteristic of Industry 4.0 [79].Lean management is not only based on theory, but is applicable in practice, as many successful companies around the world have proven.Many companies are leading by example, e.g., Toyota production system [80].They invest very large amounts of money and effort in the development of their own efficient production systems based on lean principles.Many papers carried out research to define frameworks and Lean tools that companies need [81][82][83].Design and implementation of such a program of continuous improvement can significantly reduce production losses and the company can be more competitive in the market.

Towards Sustainability
With adoption of new technologies, it is inevitable to develop new business models.By using smart data, this development has to be exploited for anchoring new, sustainable business models [84].Designing better business models requires insight into rebound effects and the potential for companies to influence sustainability impacts regarding environmental, social, and economic segments [85].The main challenges in building the sustainable business model are the balance between profits, social and environmental benefits, reconfiguration of resources and processes for new business models, integration of technologies with business model as a multidimensional and complex task, and usage of the existing business modeling methods and tools [86].Nevertheless, a significant business model was developed by the European Foundation for Quality Management (EFQM): the EFQM 2020 model [87].It represents an updated EFQM business excellence model with focus on sustainability, and the model is aligned with the United Nations Sustainable Development Goals.It shares many features with Industry 4.0, especially in the context of transformation and improved organizational performance [88].
In the literature, it is stated how the usage of Industry 4.0 technologies has positive effects on organizational performances.Analysis of the data collected by Duman [89] showed improvements in organizational performance after the usage of Industry 4.0 technologies.Important organizational performance indicators, such as production amount and speed, capacity, quality, and profitability, increased and costs decreased after introduction of the Industry 4.0 technologies.Other studies support this opinion of the positive relationship between Industry 4.0 technologies and organizational performances [90][91][92][93].
An important dimension of introduction of technologies related to Industry 4.0 and 5.0 is the efficient usage of energy.New technologies always have an environmental impact, i.e., on the one side, digital technologies demand energy, but on the other side, they save energy.This opens a question: To what extent do industrial paradigms affect environmental sustainability, and is society prepared to deal with those challenges [94]?The adoption of new technologies has negative impacts on the environment, such as air pollution and intensive use of raw materials and energy [95].However, by adoption of new technologies, the energy can be reduced by analyzing data during the production process and across the supply chain [96].Furthermore, the process of the technology selection should include environmental and social criteria in order to select technology that is greener and more sustainable, although it can be less productive, at the same time [97].
The important aspect of sustainability and technology is in information logistical waste in the process.The problem with waste of information is recognized during the design and production process and through the supply chain [98,99].The wastes in the process are related to three parts of data processing: data generation and transfer, data processing, and data storage and data utilization [100].In data generation, its selection, and evaluation, it is important to collect as much data as necessary and as little as possible to evaluate them according to the content, meaning, and origin.Waste in form of wait periods and data storage matters, particularly regarding data availability in real time.Latencies in the system as well as unprocessed data lead to delays which affect processes.Transfer, movement, and search especially include manual activities, and information is not available in real time, especially when it is written on paper.For data collection or any other work with data, the manual activities should be avoided.The continuous improvement within the manufacturing processes can only be gained by linking and analyzing data.
In existing research about the sustainable energy by using Industry 4.0 technologies, there are data of about 10 to 30 percent of energy reduction for using augmented reality, 5 to 27 percent for using additive manufacturing, around 70 percent of energy savings by using the cloud computing, and 11 to 14 percent global energy reduction using big data and analytics [101].
Another important aspect which has received more attention within Industry 5.0 is the question of ethical use of technology [102,103].This aspect is closely related to humancentricity, but it is overlapping with sustainability, because low ethical standards produce unsustainable society.Unfortunately, Industry 4.0 also has an ideological aspect in the context of philosophies of transhumanism and posthumanism [104].These philosophies attack the historical practice in which technology is subordinated to humans, never vice versa.It must be said that, in a way, Industry 4.0 was subordinating human workers to technology.However, the approach of Industry 5.0 is completely ethical and it subordinates technology to the human worker, as the European Commission's document clearly states [39]: "Rather than asking what we can do with new technology, we ask what the technology can do for us".
From Section 3.2.and Figure 5a, it is visible how Industry 4.0 relies on technology to achieve sustainability through different segments of data collection and analysis towards cloud computing.However, from Figure 6a, it is clear how Industry 5.0 is oriented towards human-centricity to resolve mentioned questions of technology adaptation to the human workers, including important ethical aspects.

Towards Resilience
Resilience, as the ability to withstand disruptions and catastrophic events [105], which relies on people, has not been significantly represented in the concept of Industry 4.0 by the research community.At the moment, there is strong orientation of the literature towards resilience in the context of technology [12], which will be discussed in the below paragraph.It is rarely explored how to rely on people when it comes to resilience.In the developed resilience model by [106], people are one of the most important components because they are the first ones to detect the anomalies and their training and education, awareness building, and leadership, as well as skill and talent, are crucial factors.The strategic human resource management is instrumental in developing requisite knowledge, skills, abilities, and other attributes and in invoking the appropriate collective routines and processes to generate the resilience outcomes [107].The strategic human resource management can be a critical point [108].
Organizational resilience is a multidisciplinary concept that has its internal and external factors.It represents the ability to overcome the problems caused by internal or external factors.An organizational resilience implies the understanding of the situation, adaption to the new situation, and managing the vulnerabilities.The firm's capacity for developing resilience is derived from a set of specific organizational capabilities, routines, practices, and processes by which a firm orients itself, acts to move forward, and creates a setting of diversity and adjustable integration [107].Management risk is an important internal factor for resilience.It includes risk plans and prevention techniques.Many studies emphasize information visibility as a crucial factor.Implementation of the key technologies has a positive impact on resilience [109].New technologies offer the ability to track information that supports organizational resilience.There are positive and negative experiences with introduction of new technology and expectations of it.Each technology should be introduced with special care and consideration about what data it can generate and what benefits it can bring for organization.
Industry 4.0 brought many challenges from the aspects of security, resilience, and efficiency of digital data and systems.Cloud computing is an IT architectural model where computing services are abstracted and delivered to customers on demand, in a self-service way, independent of device and location [110].Even though there is advanced technology, the information integration across industrial segments, levels, and processes is still a challenge.There are three major integrations in Industry 4.0: horizontal integration, vertical integration, and end-to-end integration.Since the vertical integration represents supply chains, horizontal integration represents collaborative networks [111], also known as production networks, manufacturing networks, and social manufacturing [112].The COVID-19 pandemic has shown that supply chains can be easily broken, so the collaborative networks are also seen as emergent networks that can replace a broken supply chain and increase the resilience of the manufacturing industry [113].
To achieve integration, it is necessary to change simple information systems to the smart platform [49,112].In the smart platform there are often high data flow rates and intensive processing requirements, which can cause insufficient system resources for processing to maintain high reliability and resilience [114].Another challenge is lack of confidence of the industry users in using new technologies, especially from the aspect of data security.To address this, the blockchain technology can support Internet of Things technologies for information exchanges during the different processing stages within a trusted network.Potential applications of blockchain in Industry 4.0 are expected to contribute the following [115]:

•
Resilience-being a decentralized peer-to-peer network, blockchain has no single point of failure; it is a durable and immutable ledger; transactions once recorded cannot be altered.

•
Scalability-the computing capability of blockchain network scales up as more and more peers join the network.

•
Security-all transactions on the blockchain are secured by strong cryptography; as everyone on the network knows about all transactions, they can be easily audited and cannot be disputed.

•
Autonomy-blockchain can enable all the components of the CPS to carry out mutual transactions autonomously without the need for a trusted third party; every component has a blockchain account.
However, the blockchain technology is not always an appropriate choice for every firm and has its own challenges, so the need for the blockchain technology in Industry 4.0 can be evaluated according three areas: data exchanges, trusted payments, and data storage [116].Table 1 summarizes the connection between key enablers for Industry 4.0 and Industry 5.0 and people, organization, and technology.

Discussion
The main guideline of why this review and analysis of paradigm shift from Industry 4.0 to Industry 5.0 relies on three segments: people, organization, and technology, comes from existing literature and previous research.In addition, these segments are essential for any manufacturing company, so this paper leads the reader through the basic concepts of each paradigm and essential segments in practical context.The connection between basic concepts of paradigms and these three segments, as is represented in the third section, is important:

•
To achieve the goals of each paradigm, where it is crucial to be aware how key enablers are interconnected.

•
To review the company's weak points according to the connections of key enablers, so as to know the areas of further action for improvement.

•
To rethink the human centricity approach in a company's environment, to adapt technology and organization to people and provide good working conditions as people deserve.

•
To assess the sustainability when introducing the change from technological, organizational, or any other aspect.

•
To question one's own ability to adapt to changes imposed by either external or internal factors affecting the company.

•
To improve a company's organizational performances.

•
To strike a balance between effort and investment in change in terms of manpower, organization, and technology.
Another crucial part which follows up on the importance of the connection between the basic concepts of paradigms is the readiness to introduce any feature of new paradigms.The production system or the process that is observed should be ready for that step.A wide range of maturity models are dedicated to the aspects of technical and social systems maturity [117].The maturity models are increasingly being applied in the area of information technologies [118,119], but especially in digital readiness [120].There is strong interest from authors in development of maturity models as crucial to adopt new technologies.There are several maturity and readiness models related to Industry 4.0.Through a brief review of existing maturity and readiness models, it is visible that their assessment approaches have a lot in common (Table 2).Models are focused on items for the maturity indication and the range of items' levels.However, in Table 2 it is visible how these models do not cover basic driving concepts characteristic for Industry 5.0.In the models there is a very poor orientation towards human-centricity, sustainability, or resilience.The maturity model includes the technologies characteristic for Industry 4.0, it allows to compare various technologies in terms of their contribution to the three dimensions of sustainability (economic, environmental, and social). -- The assessment of the company's readiness and maturity to introduce any aspect of new paradigms represents the basis.Furthermore, the reasons for introduction are different.In the literature, is stated how the intentions to use Industry 4.0 technologies are more influenced by the expected increase in efficiency than by pressures from suppliers, customers, or even competitors [126].On the other side, other results yield that the market uncertainty of the business is a significant driver for adoption of Industry 4.0 technologies [127].For whatever reason, the broader consequences of this introduction should be considered, as well as the human aspect.Additionally, a useful aspect will be the development of a measurement system that can give information about how organization and production benefit from the introduction of the concepts of new paradigms.

Conclusions
This review and analysis of paradigm shift for the people, organization, and technology highlights the challenges to introduce the concepts of new paradigms in each essential segment of manufacturing.In contrast with previously published reviews, the goal of this review was to develop a connection matrix between key enablers for Industry 4.0 and Industry 5.0 and essential segments of each manufacturing: people, organization, and technology.People will always be the main drivers of the activities in the production system.The humans that create and manage production systems need support in preparation of infrastructure and resources for introduction of new technologies.In further steps, they need support in transferring the knowledge from a virtual to physical world, and vice versa.This requires future research in domains of adaptation of technology to humans.Significant effort should be made in areas of data collection and interpretation through different useful reports, so that people can make their decisions based on the real-time data.In parallel, there is an effort to create robots that are autonomous and that can collaborate with people.However, these efforts should be made keeping in mind the influence on the sustainability and resilience.On the one side, there are organizational, social, and ergonomic aspects where technology should be at people's disposal, but on the other side, there is energy reduction to satisfy environmental aspects.The crucial aspect is balance between all essential segments in the context of new paradigms, but always keeping human in the center.Generally, the Industry 5.0 paradigm brought the change of main research objectives from sustainability towards human-centricity.From the managerial perspective, it means focusing on workers' education and lifelong learning, instead of focusing on purchase of new technology, or similar.In comparison with Japan and South Korea, the USA and EU are still not investing enough in education of workers, which is becoming an essential issue.Furthermore, it is also important to consider the limitations of this research that are mainly linked to search criteria (keywords).Sometimes the keywords for the paper are not properly selected; thus, applying the keywords filter during the search excludes some high-quality papers, and perhaps includes some papers of lower quality.The future research could use wider search criteria, such as filtering of abstract instead of keywords, in order to create more profound analysis of this topic.Finally, in the future research, the proposed connection matrix can be extended and discussed within the context of specific subareas (i.e., specific subarea for technology can be augmented reality) and all effects of subareas can be seen from the aspect of basic driving concepts and key enablers for each paradigm.
