Emerging Risk Management in Industry 4.0: An Approach to Improve Organizational and Human Performance in the Complex Systems
Industry 4.0 in the contemporary operating context carries important sources of complexity. This context generates both traditional risks and emerging risks that must be managed. The management of these risks includes both industrial risks and occupational risks, since they are heavily interlinked. The human factor can be considered the main link between both types of risks. Thus, understanding risks originating from human errors and organizational weaknesses as causes of accidents and other disruptions in complex systems requires elaborating sophisticated modeling approaches. Therefore, the objective of this paper is to propose an organizational and human performance approach to improve the emerging risk management linked to the complex systems, like as Human-Machine Interactions (HMI) and Human-Robot Interaction (HRI). To fulfill this objective, we first introduce the concept of emerging risk linked to human factor. Then, we introduce the concept of emerging risk management in the Industry 4.0 context. Under this complex context, we expose the concept considering the current models of risk management. Finally, we discuss how enhancing human and organizational performance can be achieved through risk management in complex systems linked to Industry 4.0. Therefore, we conclude that while Industry 4.0 brings numerous advantages, it must contend with emerging risks and challenges associated with organizational and human factors. These emerging risks include industrial risks as well as occupational risks. Moreover, the human factor aspect of Industry 4.0 is directly linked to industrial emerging and occupational emerging via context of operations. To cope with these new challenges, it is necessary to develop new approaches. One of such approaches is Complex System Governance. This approach is discussed along with the need for adequate organizational and human performance models dealing with, for example, experience from other domains such as nuclear, space, aviation, and petrochemical.
The concept “Industry 4.0” has its origin in a “strategic initiative” of the German government in 2011 . In its simplest form, this concept is a name given to the current trend of automation and data exchange in manufacturing technologies. Industry 4.0 encompasses elements of cyber-physical systems (CPS), Internet of Things (IoT), cloud computing, and cognitive computing . Industry 4.0 and its synonyms, such as Smart Manufacturing, Smart Production, Internet of Things, or the 4th Industrial Revolution , have been identified as major contributors in the context of digital and automated manufacturing environment . Kagermann et al.  note that such concepts are linked to smart manufacturing systems configured with digital networking of production. In addition, the concept “advanced manufacturing” is related to a greater interval of industrial modernization. The scientific interest around these terms is clearly increasing during the last years .
In contrast to conventional forecast based production planning, Industry 4.0 enables real-time planning of production plans as well as dynamic self-optimisation . The productive model based on Industry 4.0, in addition to improving processes in terms of efficiency and quality, can help improve safety as well as sustainability and the industry image . However, industrial processes configured for advanced manufacturing processes and technologies can increase levels of complexity of production processes and introduce high dynamism into processes creating the so-called smart working environments [8, 9]. Taking the context of critical infrastructures as a reference, Zio  suggests that the industrial processes under the Industry 4.0 paradigm can be considered complex, made up of many components interacting in a network structure. These components can be physical and cyber-physical, functioning heterogeneously, organized in a hierarchy of subsystems, and contributing to system as a whole.
However, there is scarcity of literature discussing issue of complexity in the context of Industry 4.0. Table 1 is developed to support this thesis. The first scientific publications emerged in 2012. Thereafter, there has been increased interest in the concept of Industry 4.0.
In relation to enterprise production and operation, Industry 4.0 has four objectives : environmental sustainability, safety, agility, and high efficiency. It has been suggested that Industry 4.0 environment will lead to a new revolution in the domains of safety management practices with “out of the box” thinking . However, this suggests that the management of those organizations brings new challenges given significant uncertainties associated with increasing complexity .
Suffice to say that traditional industry has its own problems. When these problems are coupled with emerging paradigm of Industry 4.0 along with emerging complex, there emerges a need for development of rigorous and sophisticated approaches for risk management (i.e., traditional and emerging risk management). Roig and Brocal  suggest management of emerging risks through combination of different approaches to provide more enlightened decision-making.
Interestingly, despite an increase in number of scientific publications on the subject of “Industry 4.0” (Table 1) the number of publications addressing “risk” and “Industry 4.0” is very low. Table 2 highlights this concern with the following search in “Web of Science” (search standards used in Tables 1–3; the results are null for the following queries: TS=(“Industry 4.0” and “risk management”); TS=(“Industry 4.0” “emerging risk”)).
The management of these emerging risks includes both industrial risks and occupational risks, since they are heavily linked . The human factor can be considered the main link between both types of risks. In such cases, concepts of Human-Machine Interactions (HMI), Human-Computer Interaction (HCI), and Human-Robot Interaction (HRI) can be considered among the most important [4, 7, 15]. In an equivalent way to the results shown in Table 2, the number of scientific publications that integrate the concepts Industry 4.0, safety, and occupational safety is still very scarce, as shown in Table 3. In this way, Badri et al.  indicate that published research on the integration of occupational health and safety (OH&S) in the Industry 4.0 context is rarely cited.
Thus, understanding risks originating from human errors and organizational weaknesses as causes of accidents and other disruptions in complex systems requires elaborating sophisticated modeling approaches. Therefore, the objective of the present research is to define an approach for organizational and human performance that can be used to improve the emerging risk management linked to the complex systems under paradigm of Industry 4.0. To obtain this objective, the rest of this paper is organized as follows:(i)Section 2 introduces the concept of emerging risk linked to human factor in Industry 4.0 context.(ii)Section 3 introduces the concept of emerging risk management in the Industry 4.0 context. Under this complex context, authors expose the concept considering the current models of risk management.(iii)Section 4 is organized to provide ways to improve organizational performance with the goal of improving safety in the complex systems linked to Industry 4.0
2. Emerging Risks
The definitions and risk models used in the professional and scientific fields are numerous. In this regard, Aven  has made a classification of definitions on risk most commonly used. Said author considers that the definitions collected in Table 4 are the most relevant. Aven  argues that the definition or model (3) is the most appropriate.
From a standardized perspective, ISO 31000:2018 standard indicates that a risk is usually expressed in terms of risk sources, potential events, their consequences, and their likelihood . In OH&S field, the ISO 45001:2018 standard defines an OH&S risk (the terms ‘‘OH&S risk” and ‘‘occupational risks” are used as equivalent in this paper) as the combination of the likelihood of occurrence of a work-related hazardous event or exposure (s) and the severity of injury and ill health that can be caused by the event or exposure(s) . These definitions are among the models on risk collected in Table 4, highlighting the adaptation of model (2) to the definition of occupational risk.
The application of these definitions and models needs adaptations and new approaches when dealing with emerging risks, which are discussed in the following sections.
2.1. Emerging Risk Concept
Generally, when the term “emerging risk” is mentioned, this term refers to any risk that is new and/or increasing. However, other perspectives do exist. For example, the International Risk Governance Council [22, 23] suggests that emerging risk should be viewed from a “systemic” perspective. A systemic perspective of risk includes both (i) emerging and (ii) new conditions. First, the risk is emerging when it is new in a broad sense, as, for example, in the case of new technologies, new materials, etc. Second, the risk is emerging when being familiar or traditional; it is presented under new or unfamiliar conditions (e.g., the reemergence of the poliovirus). In both cases, uncertainty is the main characteristic of emerging risk . From this perspective, the emerging risk adapts especially well to model (4) (R=U). However, the IRGC  notes that this uncertainty is related to the probabilities and/or consequences of the emerging risk. In this way, model (2) would also be applicable.
Brocal et al.  have proposed a theoretical framework through which the new and emerging risk (NER) concept has been modeled, especially in industrial processes. The risk model used as a reference is the following: a risk (R) is a structure consisting of five components: the source of risk (SR), causes (C), events (E), consequences (CO), and the likelihood (L); this set may be expressed as (8):(8)
From this framework, Brocal et al.  have developed TICHNER (Technique to Identify and Characterize NERs) technique that aims to identify and characterize the NERs generated by a manufacturing system. TICHNER is based in the definition of NER considered in the reports published by EU-OSHA [26–29]. This definition has been codified by Brocal et al.  through the so-called conditions that define an NER (C1, C2, C3, C4, C5, and C6), which are collected in Table 5.
Given that a NER is any risk that is new and/or increasing, Brocal et al.  consider that a risk is new (NR, new risk) when it can be associated with conditions C1, C2, and C3. Considering model (8), condition C1 is linked to new SR and new C. The novel aspect can be both technological and organizational. C2 and C3 are linked to new SR, C, E, and CO. In this case, the novel aspect of C2 is associated with changes in social perceptions and the novel aspect of condition C3 to new scientific knowledge about risk. These authors consider that a risk is increasing (IR, increasing risk) when it can be associated with conditions C4, C5, and C6. Condition C4 is linked to the increase of SR, C5 to the increase of L (exposure level and/or the number of people exposed), and C6 to the increase of CO (seriousness of health effects and/or the number of people affected).
Considering the above aspects, Table 5 shows the different possible combinations between the Ci conditions and the risk components that can form an NER (NR and/or IR). Thus, depending on the combination in each case of interest, that is, the characterization of emerging risk according to Brocal et al. , the risk could be analyzed with one of the models in Table 4.
The terms ‘‘new and emerging risks (NERs)” and ‘‘emerging risks” are used as equivalent in this paper. However, some significant differences can be found in the technical and scientific literature. These differences, according to Brocal  and Cantonnet et al. , point at a clear problem of consensus on terminology and interpretation around emerging risk. The works of Brocal et al. [17, 25] propose approaches and models to reduce the associated uncertainty.
It would be desirable that the terminology regarding these risks (i.e., “new and emerging risks,” “emerging risks”) is standardized. In this case, the CWA 16649: 2013 document may prove to be the first step. Currently, International Organization for Standardization (ISO) is developing the ISO 31050 standard—Guidance for managing emerging risks to enhance resilience .
2.2. Emerging Risks Linked to Human Factor
The effects of Industry 4.0 on OH&S generate advantages and drawbacks that could generate emerging risks . These emerging risks include both industrial risks and occupational risks, since they are heavily related . Arguably, human factor is the main link between industrial emerging risks and occupational emerging risks in advanced manufacturing processes. This may as well be the case, given the complexity of operational and the shifting business environment that continues to overwhelm human cognitive capacities [8, 33–37].
Consequently, one often tries to use mental and intellectual “shortcuts” in finding “easy” explanations or solutions taking into account directly visible parts of the whole context only. The complexity of modern systems generates the opacity where some significant risks become systemic and may be well hidden and lurking beneath until conditions reunite for their full display. One of direct consequences of those changes is the nature of the risks which continue to occur. While undesirable events such as industrial accidents, process and supply chain disruptions, or bankruptcies formerly occurred from known causes and factors, contemporary events usually originate from unanticipated interactions between elements with no visible links [12, 38–40]. In tightly connected complex systems and their environment, it creates conditions for cascading events throughout them [10, 38, 41–49] due to increased interdependencies [50, 51]. Several authors argue that analyzing the performance of complex systems should also imply a careful examination of low level events as well as organizational factors such as safety culture and the incentive system, which shape human performance and affect the risk of errors [37, 39, 52–56].
2.3. Emerging Risks Linked to Complex Systems
The technological evolution, including the introduction of the concept of Industry 4.0, and the contemporary operating context significantly contribute to increasing complexity . Some authors categorize it as a “structural complexity” issued from the heterogeneity of system components across different technological domains. It is a result of increased integration of various technological systems. There is also the “dynamic complexity” which is revealed by an emergent (usually unanticipated) system behavior as a reaction to local perturbations and stimuli in its environment . For example, the integration of modern technologies and new control rules (Industry 4.0) creates additional opacity in systems.
In this regard, concepts such as Human-Machine Interactions (HMI) and Human-Robot Interaction (HRI) can be considered among the most important [4, 7, 15]. HMI and HRI can be considered sources of risk (SR). From this perspective, Brocal et al.  have applied the TICHNER in order to identify and characterize emerging risks linked to HMI and HRI. These risks are heavily linked to conditions C1, C4, and C5. In this regard, tasks that involve human control of automated equipment are increasing , including the expansion of HRI . With the increase and development of the cobots, these emerging risks are evolving towards scenarios with greater uncertainty, due to (i) the greater flexibility and mobility of the cobots as well as their greater interaction with the workers [8, 57] and (ii) the challenge of increasing the sophistication of the tasks carried out by this type of robots .
The increase of this intelligent equipment can lead to connecting the causes of human error with the “smart machine error” . Likewise, the increase in the number of degrees of freedom of the robots also increases their complexity, increasing the risk of entrapment and the difficulty for humans to predict their movements . As the manufacturing tasks become more individualized and more flexible, the machines in smart factory are required to do variable tasks collaboratively without reprogramming . The reliability of such devices is more difficult to predict as the complexity of these systems increases .
Brocal et al.  have classified the above emerging risks into two groups, in light of their consequences (CO): accidents risks and psychosocial and musculoskeletal risks. The accidents risks in automated environments are closely linked by human errors . Among other causes, it highlights human monitoring and control of processes through control systems, instead of direct control , which can lead to a reduction of the practical knowledge of the process  and therefore result in over-reliance on automated safety systems . In relation to psychosocial risks and musculoskeletal risks, they can be studied independently or jointly, since they are interrelated, especially in automated contexts. In these contexts, considering the work of Flaspöler et al. , the main interrelated causes (C) are low physical activity; static postures; high mental workload, for example, during the monitoring and control of the processes indicated by Chidambaram ; reduced privacy at work (mainly because new technologies allow closer and more intrusive supervision); and increase of problems in decision-making.
3. Emerging Risk Management
The increase in organizational complexity in manufacturing processes is changing from centralized decision-making towards decentralized instances. In decentralized instances, decision-making can be taken by workers or by equipment where artificial intelligence is integrated . This increase in the complexity of Industry 4.0 affects the OH&S especially in terms of work content, management, and other organizational factors .
Based on the work of Brocal et al. , risk management systems in the context of Industry 4.0 can be classified into four hierarchically interrelated types: risk governance, risk management, OH&S management system, and emerging risk management. The main models, according to this classification, are discussed in the following section below.
3.1. Risk Management Models
From a global level, IRGC  proposes a framework for risk governance. This framework provides a guide for the design and application of comprehensive assessment and management strategies to deal with these risks. SRA  defines risk governance as the application of governance principles to the identification, assessment, management, and communication of risk. Thus, the process of risk management may be considered integrated into the overall process of risk governance.
In relation to risk management, ISO 31000:2018 standard provides guidelines and a common approach to managing any type of risk. This standard defines risk management as coordinated activities to direct and control an organization with regard to risk. SRA  defines risk management as those activities to handle risk such as prevention, mitigation, adaptation, or sharing.
In OH&S field, the ISO 45001:2018 standard defines management system as a set or interrelated or interacting elements of an organization to establish policies and objectives and processes to achieve those objectives; and OH&S management system is a management system or part of a management system used to achieve the OH&S policy.
3.2. Emerging Risk Management Models
IRGC  addresses emerging risks linked to technology and industrial processes. The methodological aspects for early identification and management of emerging risks are described by the IRGC Guidelines for Emerging Risk Governance . These methodological aspects are flexible and adaptable, especially in complex and uncertain contexts .
The IRGC  has reviewed emerging risk governance frameworks, and it has selected five:(i)ENISA: European Union Agency for Network and Information Security(ii)EFSA: European Food Safety Authority(iii)Swiss Re SONAR system(iv)Dutch framework (emerging risks related to the use of chemicals)(v)CEN workshop agreement (CWA) 16649:2013 (emerging risks related to technology)
CWA 16649:2013 proposes the Emerging Risk Management Framework (ERMF). The whole process is based on the concept that emerging risks go through a maturation process . This ERMF is based on the risk management frameworks defined by IRGC  and ISO 31000: 2009. Currently, International Organization for Standardization (ISO) is developing the ISO 31050 standard—Guidance for managing emerging risks to enhance resilience . This new standard has taken CWA 16649: 2013 as one of its references .
4. Ways to Improve Organizational Performance to Improve Safety in the Complex Systems
As discussed above, the introduction of the concept of Industry 4.0 brings numerous advantages, but also some new issues. It includes, among other things, emerging risks related to rising complexity of technological systems. One has limited knowledge upon them due to lack of long-term observation data. This situation is fairly challenging for management, organizations, and individual workers as a whole.
This section presents a discussion on how to enhance human and organizational performance aiming at improving risk management in complex systems linked to Industry 4.0.
4.1. Challenges Related to Organizational and Human Performance
Komljenovic et al.  provide a comprehensive review of research works regarding organizational and human performance in analysis of industrial accidents where complexities, systemic risks as well as organizational and human performance, are seriously involved.
A constant deviation toward danger or failure seems to be one of their key characteristics. The latter is practically impossible to grasp in traditional of chain-of-event analyses.
All this requires overcoming the traditional static approach to risk, through the development of dynamic risk management models oriented towards the organizational and human performance, which is strongly linked to the complex systems characteristic of Industry 4.0.
4.1.1. Dynamic Management
Industry 4.0 provides digital management of operations in new technological devices, improves working conditions, and generates a safe manufacturing environment for workers [4, 8]. In this way, this technological development allows the integration of advanced safety systems. Among them, the use of Virtual Reality (VR) stands out to create a risk-free virtual learning and training environment, applications for the use with mobile devices or wearable computing, and the use of RFID technology . Among the main applications of RFID technology is the Workforce Management and the Enhancing Safety, which allows, for example, real-time control of access to dangerous areas, as well as emergencies .
In the work environment of Industry 4.0, a wide range of examples of smart materials, smart personal protective equipment, and other advances technological applications is improving the OSH . Such context production workers provide immediate feedback of production conditions via real-time data through their own smart phones and tablets . In this context, the safety management is one of the most important issues , where Podgorski et al.  have proposed a framework based on new dynamic risk management paradigm. In this way, one of the challenges of Industry 4.0 is the difficulty of managing dynamic risk, as well as the availability and presence of experts in OSH .
Thus, during the last few years, new approaches and methodologies have been developed for risk assessment and management considering the dynamic evolution of risk . The main objective of the dynamic risk assessment is to provide an estimate of the risk over time that reflects the current condition of the system, considering for it the integration of the effective aggregation of heterogeneous information .
4.1.2. Organizational Performance
It seems that the understanding of events is changing given that one of the main sources of risks (SR) nowadays is the organization . Majority of undesirable events (E) has essentially organizational components. One considers “organizational” factors that understand a collective behavior (e.g., centralization and decentralization and organizational clarity). These characteristics come from the evolution of two factors: (i) the category of fences (physical or nonphysical) insuring a safe operating environment and (ii) the new couplings between factors that were formerly nearly independent. The latter is even pushed further with Industry 4.0.
Barriers that allow normal operation progressed with both the complication of work and the more involved persons. Therefore, this new context complicates the detection of flaws in these barriers, leading to undesirable events and failures. Such situations bring degradation of operational and safety margins. They may be locally and individually acceptable, but the sum of effects may have important unanticipated consequences that are not captured by a local analysis. The complexity of the operating environment involves a solution at the organizational level in order to cope with new challenges [12, 34, 39, 45, 70–74].
There are also studies investigating the hypothesis that modern enterprises depend on the deployment of cognitive capacities . The authors argue that there are severe limitations on these capacities in a phenomenon they identify as “functional stupidity.” “Functional stupidity” represents a lack of critical thinking, a deliberate condition of ignorance evading defiance to the status quo. This type of pathology is usually widespread in settings ruled by economy in persuading [75, 76]. Such a situation may lead to types of administration curbing or marginalizing suspicion and suppress effective communications. On the other hand, this context brings a structure of interior discussions in such ways favoring positive storylines and marginalizing undesirable ones. Thus, those situations may lead to reducing capacities of the innovation and creativity creating more fragile organizational structures that are vulnerable to both internal and external threats and perturbations, particularly in complex modern enterprises.
4.1.3. Human Performance
The behavior of people is basically shaped by their milieu. Marais et al.  analyze situations where one does not always anticipate inadequate behavior. It seems that autonomous decisions across organization may lead to unexpected combination with harmful, often surprising, impacts on both the performance and safety. Additionally, Katina [75, 78] using a synthesis of literature suggests that decision-making and actions are influences by norms and personal attitudes, organizational structures, knowledge base, and social context, degree of connectivity, race and ethnicity, mass media, and national ideology. This suggests a need for consideration of cognition, system, and environment as well as their interplay. Furthermore, a tangible reduction of undesirable events, such as accidents, major process interruptions, or bankruptcies, involves a deep understanding of human and organizational performance issues.
As far as the rationality of decision-making is concerned, several research works indicate that one cannot assume that it is always rational [12, 35, 72]. Cognitive and motivational biases are usually part of the decision-making process. Cognitive bias is defined as “a systematic discrepancy between the “correct” answer in a judgmental task, initiated through a formal normative rule, and the decision maker’s actual response to such a task.” Motivational biases describe a distortion in decision-making regarding outcomes, results, or choices . Those biases usually have a negative impact on the wanted outcomes and performance of organizations.
4.1.4. Complex Systems
The complexity and the opacity of modern systems bring difficulties to the staff to predict its overall behavior as a function of its individual components. The complexity is a system property and results from interactions between its components/subsystems, humans, HMI, HRI, etc. It generates unanticipated and emergent comportment of the system, often intensified by ill adapted operator’s actions to those situations.
HRI can be a paradigmatic industrial and occupational example of this complex and challenging context, where Vasic and Billard  propose the design of new sensing technology and of fast sensor fusion algorithms (i) to track multiple moving targets in real time, (ii) to achieve robust detection of human motion in order to build good predictive systems, (iii) to ensure robust detection of contact between robots and surrounding living agents in multiple points, and (iv) to develop fast responsive controllers that can replant trajectories in complex, cluttered environment in real time.
Several research works highlight the importance of detecting and cautiously analyzing warning flags, precursors, near-misses, and “low-level” events in order to avoid system level break-downs, process interruptions, and/or major accidents. Therefore, organization should have enough organizational, economic, and technological resilience and flexibility applicable in a large number of different and (un)anticipated situations [12, 36, 37, 39, 55, 81].
As far as human performance is concerned, it is important to understand the error itself. Some research works have shown that both success and failure pathways apply the same intellectual processes, and only the consequence changes. So, the undesired outcome qualifies an action as an error, and it is essential to find its cause. Analyses shall find out why an event occurred (“direct cause” related to preventive and mitigating barriers as well as error precursors) and why it was not stopped (“fundamental cause”). It also has to investigate the organization and its performance (expanded fundamental causes). Considering that it is almost impossible to determine a true causality in complex systems, those analyses become a difficult undertaking in a modern industrial setting. Stock and Seliger  propose approaches to address the human factor and social change in Industry 4.0. For this, these authors propose through new technologies increasing the efficiency of the training of the workers, as well as increasing their intrinsic and extrinsic motivation.
4.2. Potential Approaches for Improving Human and Organizational Performance
As discussed above, the introduction of the concept of Industry 4.0 brings numerous challenges. To cope with those new challenges, it is necessary to implement both a systematic return of experience (internal and external) and a continuous improvement process and to increase organizational resilience and robustness to unexpected events. However, increasing resilience shall be thought about wisely in order to preserve competiveness, further development, sustainability, and economic viability of an organization.
The organizational resilience is a developing concept. It will not be discussed in detail here, but there are some suggested references upon the topic [10, 34, 45, 70, 71, 82–84]. This section presents suggestions regarding key elements which may reinforce the organizational resilience in the context of Industry 4.0.
4.2.1. Modeling and Measuring Human and Organizational Performance
Understanding impacts and risks of humans and organizations as contributors to mishaps, disruptions, and accidents in complex systems requires an adequate model. The model has to go further than the “simple” approach of linearly analyzing preventive and mitigating barriers, which provides quite narrow insights of the events.
Although some models exist [12, 39, 52, 53], these models are not necessarily adaptive to the context of Industry 4.0 risks. Therefore, suggesting the development of methods which will enable modeling and measuring human and organizational performance in the context of Industry 4.0 is a novel approach.
In this regard, it is necessary to adequately take account of the complexity of today’s organizations as well as their operating context. This complexity necessitates a new way of reasoning and managing contemporary organizations. The traditional approaches in modeling, analyzing, and management are not entirely adequate to do it, and new methods are necessary [12, 36].
Actually, there are numerous research works suggesting that contemporary organizations should be considered, analyzed, modeled, and managed as Complex Adaptive Systems (CAS) or Complex Adaptive Systems of Systems (CASoS) [12, 36, 73, 85]. This claim is particularly relevant with the introduction of the concept of Industry 4.0. The theory of the complexity and characteristics of CASoS are not discussed here in detail. It is suggested to consult relevant references on the topic [10, 12, 36, 40, 43, 45, 49, 71, 74, 86, 87].
4.2.2. Adaptation and Introduction of the Concept of Complex System Governance (CSG) for Industry 4.0
A possible approach for dealing with complexity in organizational setting is the application of emerging research of Complex System Governance. Complex System Governance is an emerging field, representing an approach to improve system performance through purposeful execution of design for and evolution of important metasystem roles [19, 88–90]. In this emerging field of CSG, the main roles include evolving and improving system performance essential functions enabling control, communication, coordination, and integration . Figure 1 is based on the research of Keating et al.  and provides the overall description of the SG approach (Table 6 provides elaboration of the different functions in the CSG model as suggested by Keating and Bradley’s  research). In CSG, the “metasystem” is deliberately used to imply functions and roles beyond the purview of individual systems in the “system of systems” cluster [91–93]. In Table 6, individual systems can be represented as M1. However, M1 is not listed as the concern for CSG is as the control and communication beyond individual systems (i.e., the metasystem level).
Keating and Bradley  provide the systemic representation of CSG indicated in Table 6 in which the purpose is to provide an organizing construct for the interrelated functions necessary to perform CSG. In CSG approach, the center of any systemic intervention is people with their strengths and weaknesses. In essence, this is recognition that design, execution, and evolution of a systemic intervention are accomplished by people. As such, people become the central driving force behind systemic intervention including challenges related to machine-human interfaces. The effectiveness in intervention must be a function of those who design, conduct, and have participatory roles in the intervention effort . The CSG approach includes a system mapping followed by an investigation to uncover causes of weaknesses (i.e., pathologies) in the governance structure. Pathology acts inhibiting system performance. While CSG is focused on functions enabling viability of the system, it also calls for systemic identification and assessment of system pathologies affecting governance . Interestingly, present research suggests that solutions in the CSG paradigm might involve going beyond technology “fixes” to include “socio” policy, context, and environment.
Pyne et al.  further explore concepts, methods, and tools that may help managers to cope with constantly increasing complexity issues. Furthermore, it is suggested that effective problem solving in complex domains (i.e., Industry 4.0) may need different level of “more systemic” approaches capable of matching the uncertain, complex, and dynamic behavior characterize today’s industries. Proponents of CSG approach suggest exploring the challenges in moving the CSG from the theoretical/conceptual formulation to practice.
A potential area of practice is Industry 4.0. Again, if one takes Industry 4.0 to mean the current trend of automation and data exchange in manufacturing technologies and encompassing CPS, IoT, cloud computing, and cognitive computing, there remains a case to be made for the utility of CSG in the various areas of Industry 4.0. At the onset, it appears CSG might be used to address issues related to themes of viability, governance, control, communication, coordination, and integration, as well as malfunctions (pathology) that may emerge in the different facets of Industry 4.0.
4.2.3. Benefiting from Experience of Other Industries at Risk
Main industries at risk such as nuclear, space, aviation, and petrochemical have developed different ways of coping with human and organizational performance issues. Their return of experience may be beneficial for analyzing ways to improve it within the context of Industry 4.0. Some experience and practices from the nuclear power industry are depicted below.
The Institute of Nuclear Power Operations (INPO) identifies key aspects to accomplish the quality in the integrated risk management . Some attributes are enumerated below:(i)Behaviors: the expected actions for the stages of risk management are suggested for all organizational levels from individuals to corporate executives.(ii)Organizational characteristics for effective integrated risk management: a set of principles, policies, practices, oversight, and training are recommended for achieving an all-inclusive risk management process which is elaborated and implemented.(iii)Integrated risk management warning flags: the warning flags aim at helping the staff and managers to detect undesirable conditions affecting an integrated risk management. The former are categorized by defenses aiming at minimizing risky events. The staff and managers should analyze them for stimulating discussions and draw lessons.
Such an approach may help reinforcing the overall resilience and robustness. This activity also involves a cautious analysis of organizational factors such as incentive systems that influence human performance and impact the risk of errors . This feature is also termed “Antifragility” by some researchers [42, 95]. The antifragility puts forward an idea of adaptive organizations with regard to complex and continuously altering internal and external operating context. In this case, one can suggest that internal and external complexification is also partly due to the introduction of the concept of Industry 4.0 which sometimes may overwhelm human capacity to grasp relevant factors in acting and decision-making. This implies that the paradigm of “only” technological solutions to emerging risks may be misleading especially without consideration of role of the human and organizational factor. For example, one becomes inclined to more risk taking by putting undue confidence into the technology without knowing its limits and vulnerabilities.
Therefore, improving and managing human performance risks (including those coming from machine-human interfaces) based on the experience from the nuclear power industry may also include other elements such as the following :(i)Frequently discuss risks, complexity, and their interdependence(ii)Perform gap analysis between outlooks and observations of behavior(iii)Enthusiastically lobby different opinion to avoid deliberate carelessness (reduce cognitive and motivational biases)(iv)Analyze and discuss past behaviors, including informal messages at the corporate level(v)Doubt and uncertainty should not go unchallenged(vi)Ask to demonstrate that a system is appropriately safe to function or not sufficiently unsafe to be shut down(vii)Be cautious regarding findings from a root cause investigation that one points out to the negligence; in this case, only part of the story has been exposed(viii)Enlarge the scope of defense-in-depth concept to embrace the concept of complex systems and their intrinsic nonlinearity
Undoubtedly, Industry 4.0 brings numerous advantages. However, this paradigm also carries emerging risks and challenges related to organizational and human performance. These emerging risks include both industrial risks and occupational risks. Arguably, human factor is the main link between industrial emerging risks and occupational emerging risks in the Industry 4.0 context.
Addressing these issues calls for effectiveness in dealing with traditional static approach to risk, for example, through the development of dynamic risk management models oriented towards the organizational and human performance. However, there is also a need to develop robust approaches capable of dealing with emerging risks associated with Industry 4.0. In this research, Complex System Governance is suggested.
However, there remains a need for case applications, clearly articulating the potential of such approaches. Moreover, there is no need to be limited to such approaches as Complex System Governance. This research can be extended to include technological approaches such as Blockchain Technology and the discovery of deep systemic pathological issues affecting Industry 4.0.
