                 Abstract
                 In this position paper, we discuss the socio-technical perspective of the Fourth Industrial
                 Revolution. The fourth industrial revolution refers to the novel wave of advanced technologies
                 – like Robotics, the Internet of Things, Big Data – that are adopted in manufacturing
                 organisations. Scholars and practitioners have forecasted the fourth industrial revolution, and
                 it is still underway. This situation allowed the proliferation of various visions in the fourth
                 industrial revolution literature: Industry 4.0, the socially sustainable factory of Operator 4.0
                 and Industry 5.0. Through a literature review, we analyse the manifesto and pivotal papers of
                 such visions in order to assess how they employ the socio-technical perspective. The results
                 show that Industry 4.0 vision mainly considers the technical system. The vision of the socially
                 sustainable factory of Operator 4.0 is an attempt to consider the social system in conjunction
                 with the technical system. Then, Industry 5.0 vision is socio-technical in nature and also takes
                 into consideration sustainability outcomes.

1. Introduction
    Over the last years, the development of a new wave of advanced technologies – such as the Internet
of things, Big Data analytics, Additive manufacturing - have attracted the interest of practitioners and
scholars in several sectors of the smart city [1], citizen science [2], tourism [3] and manufacturing [4].
    Within the manufacturing realm, such technologies usher the Fourth Industrial Revolution [4–6].
Several studies posit the extensive impact that such technologies have on the production processes and
on business models of manufactures [7, 8]. These technologies make the production system more
efficient and automated [9]. Thus, the fourth industrial revolution passes into the annals of history as a
forecaster industrial revolution that is still underway [10]. Several studies confirm this progress status
that is focused on the implementation issues and barriers of these technologies and the uncertain societal
impacts of such technologies [11–13].
    Since scholars and practitioners forecast the fourth industrial revolution, various visions have
proliferated in literature over the years. Therefore, in this paper, we use the label of the fourth industrial
revolution as an umbrella term to embrace all these visions (see Figure 1). The three main visions are
Industry 4.0 [5], the socially sustainable factory of Operator 4.0 [14] and Industry 5.0 [15]. Each vision
has a different manifesto embracing different technical and human factors that generate bewilderment
in literature.

                                Figure 1 The visions of the fourth industrial revolution

   This study aims to highlight the differences of human and technical factors among the three visions
by employing the socio-technical theory [16]. The socio-technical theory considers the organisation
composed of technical and social systems [17]. The joint optimisation of both systems allows the
organisation to operate efficiently, leading to instrumental and human benefits [18]. In technical
systems, the improvements concern better performance and achieved economic objectives, whereas the
improvements in the social system concern enhanced job satisfaction and a higher quality of work-life
balance. The socio-technical framework is conceptualised in Figure 2.




                               Figure 2 The socio-technical framework (based on [17])

    To this end, we conduct a literature review [19] in order to retrieve the manifesto and pivotal articles
for each fourth industrial revolution vision. Then, we analyse such studies by using the socio-technical
theory as a sensitive device. The study addresses the following research questions: “ How do the three
visions of the fourth industrial revolution embrace the socio-technical perspective?”
   The study contributes to the socio-technical literature stream by showing the socio-technical
perspective of the three visions in the fourth industrial revolution and their main differences.
   The structure of the paper is as follows. We present the research design in Section 2. The Industry
4.0 vision follows in Section 3. Then, we debate the socially sustainable factory of Operator 4.0 and
Industry 5.0 in Sections 4 and 5, respectively. We discuss the result of the review in section 6, and we
conclude the article in section 7.

2. Methodology
    We conducted a literature review on Scopus, Science Direct and Google Scholar in July 2021 [19].
We employed as keywords search: “Industry 4.0” AND “Industry 5.0” AND “Operator 4.0” AND
“Fourth Industrial Revolution” refined by articles in English included in Business, Management and
Accounting subject area. We aimed to detect and the manifesto and the pivotal articles of the three
visions of the fourth industrial. We select those articles that discuss such visions in depth. They are
literature reviews, conceptual papers or empirical papers. By reading the title and abstract, we extracted
40 articles. The authors thoroughly read the selected papers by selecting 20 papers, which we use for
this article as a starting point of the research. One of the co-authors qualitative analysed the articles




                                                        75
using as a sensitive the socio-technical theory, considering (1) how studies have enacted the presence
of the social and the technical and (2) the relative outcomes. Then, the two authors held some joint
meetings to discuss the results and, where required, make verification to reach a consensus [19].

3. Industry 4.0
    In chronological order, Industry 4.0 (I40) is the first vision of the Fourth Industrial Revolution [5].
For this reason, this label is used as a synonym of the fourth industrial revolution, but in our study, we
consider I40 as a sub-vision of this industrial phenomenon. The manifesto of I40 was encouraged by
the German Government and was released in conjunction with the “Industrie 4.0” industrial plan [5].
I40 industrial plan aims to present the I40 technologies, the technological tenets of the revolution and
the potential technological outcome on the production system [20]. In the same way, European and
Asian governments and American associations launched their industrial plans to – named “Industria
4.0”, “Industrial Internet of Things”, “Smart Manufacturing”, “Made in China 2025”, and “Industrial
Internet”- with similar principles and technologies of the German initiative [20].
      Here below, we condense a brief description of the most important I40 technologies:
    •    Internet of things describes the operation in which physical products and machinery are
         equipped with sensors like Radio-Frequency Identification in order to capture, process, and
         communicate in real-time data to humans as well as other pieces of machinery. These
         technologies require sensors and actuators to acquire and communicate through a WIFI
         network.
    •    Big Data analytics refers to technologies allowing to analyse of a massive set of unstructured
         or semi-structured data, which is not possible to analyse by traditional data process methods
         due to their complexity. Data analytics aims to reveal patterns, trends, and associations,
         especially relating to human behaviour and interactions.
    •    Additive manufacturing is an “umbrella term” that includes different technologies, such as 3D
         printing, to produce high-quality real objects by adding material rather than mechanically
         removing or milling material from a solid block.
    •    Virtual Reality, Augmented Reality, and Hologram are advanced technologies that aim at
         designing products, operation planning, factory layout planning, system maintenance through
         specific hardware and software without using real materials.
    •    Cloud manufacturing is the cloud computing technology that is applied to the manufacturing
         area. Indeed, Cloud manufacturing is mainly employed for its ability to make the entire
         manufacturing.
    The main two principles of the I40 revolution are vertical and horizontal integration. Vertical
integration is internal to the organisation and describes the integration of several organisational units,
including marketing, sales and technology development, by end-to-end digitally integrated technologies
across different levels. Horizontal integration represents the digital information sharing that facilitates
collaboration among partners within a value chain, including customers [18].
    Thus, the potential integration of different I40 technologies lays the foundation for the development
of cyber-physical systems. Such systems allow the automation of various manual and decision-making
activities previously performed by the workers.
    The adoption of I40 technologies allows improving the efficiency of the production process. The
review revealed that such adoption reduced lead-time operations, increased output quantity and quality
of productions. Furthermore, the automation of various hard muscular activities, previously performed
by workers, delivers safer tasks and work environment for workers as a positive externality. However,
at the same time, the I40 adoption opens for various social drawbacks. The extensive automation of the
production process promises to disrupt various white and blue-collar job positions. Moreover, the lack
of competencies possessed by the traditional manufacturing workers pushes the organisations to fire
them to embrace the I40 paradigm and hire workers but more competence with these I40 technologies.
    Therefore, applying the socio-technical framework to the I40 vision shows that this perspective is
merely technocentric (see Figure 3). The main focus is related to the adoption and integration of various
technologies to improve production efficiency.




                                                    76
   Although the social system is not emphasised, we found some benefits that the technical systems
deliver on the social systems related to safer tasks. Such outcomes are coupled, however, with social
drawbacks related to the job disruption. illustrates the socio-technical perspective of I40.

4. The socially sustainable factory of Operator 4.0
    The socially sustainable factory of Operator 4.0 (OP40) is the perspective of the fourth industrial
revolution by Romero et al. 2016 [14]. This is an attempt to include human agency, particularly the
workers operating along the assembly line, within the I40 production system [14]. Romero et al. 2016
wanted to rebut the I40 paradigm illustrating a socially sustainable factory where workers can cooperate
with I40 technologies. Such workers are named “Operator 4.0”, and they are defined as: a smart and
skilled operator who performs not only cooperative work with robots but also work aided by
machines”[21]. The technologies of the socially sustainable factory are I40 technologies that allow
corporations with human agency. We found as new technologies the smart exoskeleton and the cobot.
The smart exoskeleton is a wearable mobile machine supporting limb movement with increased strength
and endurance through electric motors, pneumatics, and lever. Cobots are robots designed to collaborate
with humans in safety. Cobots perform various hard muscular, repetitive, and non‐ergonomic activities
related to the movement and manipulations of objects faster than workers. We also found an increasing
interest for the virtual and augmented reality that can help OP40 activities by providing visual aid
through smart glasses or tablets.
    The main contribution of the OP40 vision is a proposed “visionary” typology of the potential
corporations between workers and technologies [14, 21]:
        • The super‐strength operator is an OP40 that conducts manual tasks equipped with a smart
             exoskeleton
        • The smarter operator is an OP40 in charge of using I40 technologies with an intelligent
             personal assistant that facilitates the interaction with the I40 technology interfaces and
             information systems.
        • Augmented and virtual operators are OP40s that perform mental, manual and maintenance
             tasks with augmented reality or virtual reality that provides visual guidance for their tasks
             and reduces mental and physical effort.
        • The collaborative operator works with I40 technologies along the assembly line—such as
             cobots of robotised arms—to maintain constant and efficient organisation’s production.
        • The analytical operator is the OP40 that examines Big Data extracted from I40 technologies.
             This operator is in charge of predicting and preventing potential critical events along the
             assembly line, such as the breaks of machinery pieces or lack of lubrication of the conveyor
             belt.
    Beyond this typology, the literature is devoted to the development of anthropocentric production or
human-centric cyber-physical systems, namely manufacturing production systems that include OP40 in
the design of the production systems. Nevertheless, the focus remains strictly technical without
imposing OP40 competence and skills that remain an open question.
    With regards to the outcome of the socially sustainable factory adoption, we found that I40
technologies can support the reduction of mental and physical stress [22] of the OP40 that, in turn, can
conduct a more efficient production process. OP40 conducts activities quickly and addresses various



                                                      77
problematic tasks along the production process, such as technology management, passing on
information, communicating statuses, and locating products, tools, and materials [23].
    Therefore, the application of the socio-technical framework on the socially sustainable factory of
the OP40 vision shows that this perspective remains anchored on the technical systems but with interest
in the social system. The human agency is called OP40, and the literature reveals the potential socio-
technical interplay between the two systems by the OP40 typology. The social and technical benefits
are not so emphasised because the literature is devoted to developing an effective work system.
However, we found that socially sustainable factory adoption delivers benefits on both systems.
    Figure 4 illustrates the socio-technical perspective of the socially sustainable factory of the OP40.

5. Industry 5.0
    The term “Industry 5.0” (I50) has been a buzzword circulating since the advent of I40. I50 is mainly
used to debate the technocentric I40 vision that opens for several societal issues, particularly the job
disruption and extensive surveillance of workers from the management. The literature reports various
calls for actions of I50. The first authors using I50 were Ozdemir and Hekim [24] that debated how to
reconcile human agency and technologies in an ever more connected world. To this end, the authors
claim for a human-centric solution of such technologies, especially for cobots and artificial intelligence
- that is not part of the I40 manifesto. Afterwards, in 2019, Nahavandi [25] proposes a further call for
I50, stressing the necessity to find a solution that allows manufacturers to increase productivity while
not removing human workers from the manufacturing industry. He also claims that the adoption of I50
will create new job positions, particularly the Chief Robotics Officer (CRO). This role is in charge of
managing robots and their interactions with humans. Finally, in 2021, the European Commission
launched a more articulated call for actions for I50 [15]. I50 is based on three pillars: human-centric,
sustainable and resilient. The pillar of human-centric refers to the development of a production system
that includes workers. They use the OP40 [12] typologies to illustrate the human agencies stressing the
importance of digital competencies development and the maintenance of knowledge of production
activites for workers. The pillar sustainable refers to a production system that mitigates the
environmental impacts of the manufacturers, promoting energy-saving, cleaner production, and circular
economy practices. The pillar resilient refers to the organisation attitude to overcome economic crisis
– such as covid 19 – and maintain competitive advantages over competitors. Such conceptualisation
with three pillars resembles the triple bottom line of sustainability, claiming that the organisation should
seek profitability mitigating social and environmental issues [4].
    The technologies involved in the revolution are the same as I40 plus artificial intelligence, cobots
and exoskeleton that are used to automate activities in an ethical and fair way towards workers: they
automate repetitive activities leaving creative and problem-solving activities to the workers [26–28].
    Therefore, the application of the socio-technical framework on I50 vision shows that it is socio-
technical in nature. The social system is emphasised as much as the technical system. We found that
the OP40 role is also linked to the need for up-skill, especially for digital skills. The technical system
involves a human centre production system where automation is used in an ethical way. It is also
important that the I50 includes the so-called systematic sustainability where the socio-technical system




                                                          78
aims to produce economic benefits for the organisation, social benefits for workers and address
environmental issues for the world. Figure 5 illustrates the socio-technical perspective of I50.

6. Discussion
   The literature review reveals three main visions of the fourth industrial revolution: I40, the socially
sustainable factory of OP40 and I50. Chronologically wise, we noted that there is a shift from a
technocentric perspective, where social systems are not considered, towards a more complex socio-
technical perspective. Starting from the I40 vision, there is a lack of interest in exploring the role of
workers. The job disruption risk that I40 automation poses to society is the enabler for creating different
perspectives of the fourth industrial revolution. The socially sustainable factory of OP40 adds a sort of
typology for OP40 that can be used as an aid to design technologies allowing human interaction. This
“human inclusion” premise to the production system is embraced by the I50 vision that is socio-
technical in nature, and it is very promising for our society. Indeed, it can be used as a way to address
job disruption that is problematic when technology automation plays a crucial role in the production
processes. In addition, I50 allows linking the socio-technical theory with the triple bottom line of
sustainability. This possibility is very important for socio-technical scholars because we can move from
the “humanisation” of the workplace to the development of a “sustainable” world. More specifically,
we can use the socio-technical theory to explain how the human and technological interplay serves to
address internal issues of the organisations – in terms of job satisfaction and for an efficient and clean
production – and external worldwide issues - like the increasing pollution and better quality of life.

6.1.    Implication for researchers and practitioners
   The study has certain implications for researchers. The study results are a starting point to explore
the socio-technical perspective of the fourth industrial revolution. We propose some research avenues
that socio-technical scholars can pursue:
       •    Digital skill is a complex concept that was unpacked by Van Laar et al. 2017 that propose a
            list of contextual and core digital skills [29, 30]. It is a pivotal component of the social
            system and deserves further attention. Starting from this study, we encourage qualitative
            and quantitative studies that create a list of the needed digital skills for the fourth industrial
            revolution and test it. Also, it is valuable to create a list of digital skills in conjunction with
            the OP40 typology.
       •    Knowledge is not an object which can be captured, stored and transferred. Automation can
            impact the workforce activities for knowledge sharing and transfer within organisations,
            which hamper the workforce share to acquire know-how for superior performance. Thus, it
            is valuable to study how these activities can change in the fourth industrial revolution. What
            are the knowledge sharing and transfer activities in the highly automated production system,
            such as organisations involving the fourth industrial revolution?
       •    Socio-technical theory can also be used to explore how the management and workers pass
            from the traditional work system to a novel I40/I50 production system. In this way,




                                                        79
             researchers can shed light on the socio-technical barriers imputing organisations to adopt
             such technologies, the potential drawback of the social systems, and the practical socio-
             technical interplay in the fourth industrial revolution.
    The study proposes various implications for practitioners and policymakers. Practitioners can exploit
this article to explore the role of workers in complex automated production systems understating that
workers keep creating value for the organisations. Policymakers can use this study to corroborate the
need to develop industrial plans that provide funds for the skill development of manufacturing workers.

7. Conclusion
    The aim of the study is to illustrate a socio-technical perspective of the fourth industrial revolution.
Since scholars and practitioners forecast this revolution, we found in literature three main visions: I40,
the socially sustainable factory of the OP40 and I50. Thus, we illustrate a socio-technical perspective
for each vision. To this end, we conduct a literature review in order to detect the manifesto and
systematic literature review for each vision. The result shows that I40 is technocentric and does not
consider the social system. The socially sustainable factory of OP40 starts considering social systems
stressing on the OP40 and the potential interplay between the two systems. In contrast, I50 is socio-
technical in nature and includes the necessity to pursue sustainability outcomes (economic-
environmental and social) rather than the traditional outcome of a work system. We finally propose
some recommendations to continue the study of the socio-technical perspective in the fourth industrial
revolution.
    The study has limitations. We present the preliminary results of a literature review that we conducted
on Scopus and Google Scholar, analysing only English articles. Future studies should overcome our
study limitation by performing a literature review in different databases—such as WoS, EBSCO,
Scopus, Science Direct and Google Scholar—examining papers in different languages.
