Green ergonomics: challenges and opportunities

Addressing the causes and consequences of environmental degradation presents significant challenges for humankind. This paper considers what ergonomics/human factors (E/HF) professionals can contribute to understanding and tackling some of the issues that arise through the movement towards a more environmentally sustainable economy. These issues are considered in relation to work in green industries (specifically, sustainable energy production, recycling and organic food production), and there is a need to ensure that these jobs are safe and healthy; the design of products and systems that are ‘environmentally friendly’ to facilitate their acceptability and use and how E/HF professionals can contribute to understanding and promoting behavioural change relating to environmental choices. The activities of some international organisations in this area are identified and the potential for E/HF involvement is considered. The implications for the E/HF profession are discussed.

Practitioner summary: This paper considers how ergonomics/human factors professionals can contribute to the movement towards more sustainable and ‘environmentally friendly’ design and work. Potential challenges and opportunities are discussed in relation to jobs in green industries, products and systems and behaviour change.     

Towards a sustainable world through human factors and ergonomics: it is all about values

In this paper, we analyse two approaches that attempt to address how a human factors and ergonomics (HFE) perspective can contribute to the sustainability of the human race. We outline the principles, purposes and fields of application of ergoecology and green ergonomics, and thereafter deal with their context of emergence, and the overlaps in purpose, and principles. Shared values are deduced and related to socio-technical principles for systems' design. Social responsibility and environmental/ecospheric responsibility are the leading threads of ergoecology and green ergonomics, giving rise to the values of: respect for human rights, respect for the Earth, respect for ethical decision-making, appreciation of complexity, respect for transparency and openness, and respect for diversity. We discuss the consequences of considering these values in HFE theory and practice.     

Green buildings need good ergonomics

A retrospective post-occupancy evaluation survey of 44 occupants in two Leadership in Energy and Environmental Design (LEED) Platinum buildings on a US college campus is reported. The Internet survey covered a range of indoor environment and ergonomics issues. Results show that working in these buildings were a generally positive experience for their health, performance and satisfaction. However, in one building there were persistent issues of variability in air temperature, air freshness, air quality and noise that affected the perceived health and performance of the occupants. Although the buildings were energy-efficient and sustainable structures, ergonomics design issues were identified. Implications for the role of ergonomics in green buildings and in the US LEED rating system are discussed.

Practitioner Summary: This survey identified a number of ergonomics design issues present in the LEED Platinum energy-efficient and sustainable buildings that were studied. These results highlight the importance of integrating ergonomics design into green buildings as a component in the US LEED rating system.     

State of Science: ergonomics and global issues

In his 1993 IEA keynote address, Neville Moray urged the ergonomics discipline to face up to the global problems facing humanity and consider how ergonomics might help find some of the solutions. In this State of Science article we critically evaluate what the ergonomics discipline has achieved in the last two and a half decades to help create a secure future for humanity. Moray’s challenges for ergonomics included deriving a value structure that moves us beyond a Westernised view of worker-organisation-technology fit, taking a multidisciplinary approach which engages with other social and biological sciences, considering the gross cross-cultural factors that determine how different societies function, paying more attention to mindful consumption, and embracing the complexity of our interconnected world. This article takes a socio-historical approach by considering the factors that influence what has been achieved since Moray’s keynote address. We conclude with our own set of predictions for the future and priorities for addressing the challenges that we are likely to face.

Practitioner Summary: We critically reflect on what has been achieved by the ergonomics profession in addressing the global challenges raised by Moray's 1993 keynote address to the International Ergonomics Association. Apart from healthcare, the response has largely been weak and disorganised. We make suggestions for priority research and practice that is required to facilitate a sustainable future for humanity.     

Corporate ergonomics programme at Volvo Car Corporation

One of Volvo Car Corporation's core values is "Environmental Care". Volvo Cars has a tradition of attention to the work environment and has over the years developed a working environment management system, an organisational strategy for the participation of everyone, a working environment policy, standards/specifications and methods for efficient practical performance. The Production Ergonomics Project is an example of this. In order to achieve results in ergonomics one has to work comprehensively, which means working with the product, the process, the workplace, the individuals and the work organisation. The key to success is to train all categories concerned in load ergonomics and to perform methodical ergonomic work through the whole chain from design to production.     

The contributions of human factors and ergonomics to a sustainable minerals industry

This article describes examples of the application of human factors research and development work to a sustainable minerals industry. It begins by outlining human-related aspects of the minerals industry and the key human factors work previously undertaken in this domain. The focus then switches to sustainability in the minerals industry. Sustainability principles are introduced and illustrations provided of how human factors research and development work fits within such a framework. Three case studies of human factors in the minerals industry research are presented and the sustainability implications in each case study are highlighted. Finally, future trends related to human factors work in a sustainable minerals industry are addressed, in particular the opportunities and possible adverse consequences that increasing deployment of mining automation might bring.

Practitioner Summary: Minerals industries are a major global activity with significant sustainability implications. Aspects of sustainability in mining are examined using three case studies. These illustrate the contribution of human factors/ergonomics in reducing risks; developing emergency response management systems; and the value of participatory ergonomics in improving the design of mining equipment.     

Aircraft keyboard ergonomics: a review

The increasing use of complex digital avionics systems has resulted in the aircraft pilot making ever greater use of keyboards. The designer has comparatively little coherent information or guidance to help him select the optimal physical and functional characteristics of the keyboard, but current technology gives him a very wide choice. Much of the current literature relates to studies based on static ground environments and, although there is some evidence derived from studies of aircraft, the majority of the ergonomics data relevant to keyboard design is not easily generalized to the airborne environment. A review of the current military standards underlines this as they are brief and they are not always rigidly adhered to in practice. The factors which are likely to affect keying performance are discussed and the state of ergonomics knowledge in the area reviewed.     

Bulgarian ergonomics revisited

In his earlier and more intensive review of ergonomics in Bulgaria, the author concluded that this discipline was highly developed and enjoyed strong government support. It was found that the network of ergonomics activities across national, regional, and local industrial plant levels was perhaps the most highly organised and comprehensive extension of ergonomics concerns of any country in the world. The brief revisit described in this report revealed that ergonomics continues to enjoy a very high measure of respectability. As also noted earlier, the field of ergonomics is still largely the province of physiologists and engineers. Some psychologists that are associated with design organisations are involved in ergonomics activities but, for the most part, psychologists deal primarily with more traditional topics that fall under the heading of industrial or work psychology.     

Design and ergonomics

Using both Japanese and American annual design reports the latest industrial product designs are reviewed. The paper concludes that ergonomics plays an important role in unifying high-technology mass products with design for human use and in creating an aesthetic value in products.     

Many model thinking in systems ergonomics: a case study in road safety

In complexity science, the many models thinking philosophy argues for a multi-method approach to complex problems. This article investigates whether the use of multiple systems ergonomics methods to examine the same problem is useful, or whether using different approaches creates incompatible analyses. Five systems ergonomics analyses of road trauma are examined and their key insights extracted. The extent to which these insights are compatible with one another and can be integrated when attempting to reduce road trauma is assessed. The findings indicate that applying several systems ergonomics methods to the same problem is useful, as multiple insights are developed and deficiencies in one approach are countered by the others. Importantly, the case study demonstrates that the insights gained are compatible and support the development of holistic systems thinking-based interventions. In conclusion it is recommended that a many systems ergonomics model thinking approach be adopted by ergonomists working in complex problem spaces.

Practitioner Summary: Many model thinking uses multiple methods to understand complex problems. We explore whether this is beneficial in systems ergonomics. Five models of road trauma, developed using five systems ergonomics methods, are examined. The findings demonstrate that a many model systems ergonomics approach produces a diverse but complimentary set of insights.     

Nature: a new paradigm for well-being and ergonomics

Abstract

Nature is presented as a new paradigm for ergonomics. As a discipline concerned with well-being, the importance of natural environments for wellness should be part of ergonomics knowledge and practice. This position is supported by providing a concise summary of the evidence of the value of the natural environment to well-being. Further, an emerging body of research has found relationships between well-being and a connection to nature, a concept that reveals the integrative character of human experience which can inform wider practice and epistemology in ergonomics. Practitioners are encouraged to bring nature into the workplace, so that ergonomics keeps pace with the move to nature-based solutions, but also as a necessity in the current ecological and social context.

Practitioner Summary: Nature-based solutions are coming to the fore to address societal challenges such as well-being. As ergonomics is concerned with well-being, there is a need for a paradigm shift in the discipline. This position is supported by providing a concise summary of the evidence of the value of the natural environment to well-being.     

Nanomaterials in the field of design ergonomics: present status

Application of nanotechnology and nanomaterials is not new in the field of design, but a recent trend of extensive use of nanomaterials in product and/or workplace design is drawing attention of design researchers all over the world. In the present paper, an attempt has been made to describe the diverse use of nanomaterials in product and workplace design with special emphasis on ergonomics (occupational health and safety; thermo-regulation and work efficiency, cognitive interface design; maintenance of workplace, etc.) to popularise the new discipline ‘nanoergonomics’ among designers, design users and design researchers. Nanoergonomics for sustainable product and workplace design by minimising occupational health risks has been felt by the authors to be an emerging research area in coming years.

Practitioner Summary: Use of nanomaterials in the field of design ergonomics is less explored till date. In the present review, an attempt has been made to extend general awareness among ergonomists/designers about applications of nanomaterials/nanotechnology in the field of design ergonomics and about health implications of nanomaterials during their use.     

A survey of anthropometry and physical accommodation in ergonomics curricula

The size and shape of users are an important consideration for many products and environments. Designers and engineers in many disciplines must often accommodate these attributes to meet objectives such as fit and safety. When practitioners have academic training in addressing these issues, it is typically through courses in Human Factors/Ergonomics (HF/E). This paper investigates education related to physical accommodation and offers suggestions for improvement. A survey was conducted wherein 21 instructors at 18 universities in the United States provided syllabi for 29 courses, which were analysed to determine topics related to anthropometry and resources used for the courses. The results show that within the US, anthropometry is covered in the majority of courses discussing physical ergonomics, but important related concepts were often omitted (e.g. digital human modelling, multivariate accommodation and variability across global populations). Curricula could be improved by incorporating more accurate anthropometry, multivariate problems and interactive online tools.

Practitioner Summary: This paper describes a study investigating collegiate ergonomics courses within the US in the area of physical accommodation. Course schedules and texts were studied for their treatment of several topics related to accommodating the spatial requirements (anthropometry) of users. Recommendations are made for improving course curricula.     

A strategy for human factors/ergonomics: developing the discipline and profession

Human factors/ergonomics (HFE) has great potential to contribute to the design of all kinds of systems with people (work systems, product/service systems), but faces challenges in the readiness of its market and in the supply of high-quality applications. HFE has a unique combination of three fundamental characteristics: (1) it takes a systems approach (2) it is design driven and (3) it focuses on two closely related outcomes: performance and well-being. In order to contribute to future system design, HFE must demonstrate its value more successfully to the main stakeholders of system design. HFE already has a strong value proposition (mainly well-being) and interactivity with the stakeholder group of 'system actors' (employees and product/service users). However, the value proposition (mainly performance) and relationships with the stakeholder groups of 'system experts' (experts fromtechnical and social sciences involved in system design), and 'system decision makers' (managers and other decision makers involved in system design, purchase, implementation and use), who have a strong power to influence system design, need to be developed. Therefore, the first main strategic direction is to strengthen the demand for high-quality HFE by increasing awareness among powerful stakeholders of the value of high-quality HFE by communicating with stakeholders, by building partnerships and by educating stakeholders. The second main strategic direction is to strengthen the application of high-quality HFE by promoting the education of HFE specialists, by ensuring high-quality standards of HFE applications and HFE specialists, and by promoting HFE research excellence at universities and other organisations. This strategy requires cooperation between the HFE community at large, consisting of the International Ergonomics Association (IEA), local (national and regional) HFE societies, and HFE specialists. We propose a joint world-wide HFE development plan, in which the IEA takes a leadership role. PRACTITIONER SUMMARY: Human factors/ergonomics (HFE) has much to offer by addressing major business and societal challenges regarding work and product/service systems. HFE potential, however, is underexploited. This paper presents a strategy for the HFE community to strengthen demand and application of high-quality HFE, emphasising its key elements: systems approach, design driven, and performance and well-being goals.     

Crossing levels in systems ergonomics: A framework to support ‘mesoergonomic’ inquiry

In this paper we elaborate and articulate the need for what has been termed ‘mesoergonomics’. In particular, we argue that the concept has the potential to bridge the gap between, and integrate, established work within the domains of micro- and macroergonomics. Mesoergonomics is defined as an open systems approach to human factors and ergonomics (HFE) theory and research whereby the relationship between variables in at least two different system levels or echelons is studied, and where the dependent variables are human factors and ergonomic constructs. We present a framework which can be used to structure a set of questions for future work and prompt further empirical and conceptual inquiry. The framework consists of four steps: (1) establishing the purpose of the mesoergonomic investigation; (2) selecting human factors and ergonomics variables; (3) selecting a specific type of mesoergonomic investigation; and (4) establishing relationships between system levels. In addition, we describe two case studies which illustrate the workings of the framework and the value of adopting a mesoergonomic perspective within HFE. The paper concludes with a set of issues which could form part of a future agenda for research within systems ergonomics.

Green exploration and exploitation: Capabilities,product advantage,and policy considerations

While sustainability has been identified as a critical driver of innovation, our understanding of green innovation activities interrelationship with capability antecedents and consequences of both green exploration and green exploitation remains unclear. A preliminary framework is developed to guide hypotheses and provide insights into green innovation and its connections with new product advantage from a Resource-Advantage (R-A) perspective. A sample of 197 traditional Chinese manufacturing enterprises conducting green innovation is an input into a structural equation model. The results indicate that green exploitation has direct positive effects on both innovative eco-friendly products' customer satisfaction and differentiation, whereas green exploration only positively impacts product differentiation. Importantly, green exploitation fully mediates the connections between capability antecedents (i.e., technology capability and market capability) and new product advantage (i.e., customer satisfaction and differentiation). By contrast, green exploration only fully mediates capability antecedents on new product differentiation. Our findings shed new light on exploration and exploitation research that shapes green innovation activities. Further, it contributes greater clarity into how manufacturing enterprises translate their technology and market capabilities into new eco-friendly product advantage. Moreover, the results suggest implications for manufacturers to become both “green and competitive” as well as offer policy-makers insights into shaping programs to assist green innovation.     

Participatory ergonomics in design processes: the role of boundary objects

The aim of this paper is to introduce the concept of boundary objects in order to better understand the role of objects in participatory ergonomics (PE) design processes. The research question is: What characterizes boundary objects in PE processes? Based on two case studies, we identify eight characteristics of boundary objects and their use, which make them particularly useful in PE design processes. These characteristics go beyond the object itself and extend into the context of their use. We argue that the selection of boundary objects in PE processes is of great importance, since different objects enable workers’ participation and collaborative design in different ways. The framework developed may serve to provide criteria to guide practitioners and intervention researchers in the selection of objects to facilitate a PE process. The paper concludes with a list of recommendations for ergonomic practitioners that are based on the framework.     

Design of safer agricultural equipment: Application of ergonomics and epidemiology

A vast majority of the world's workers are employed in agricultural activities and are exposed to a wide variety of hazards. Since agriculture is primarily decentralised activity, it is often difficult to set and implement work safety norms and standards. While standards can be set for equipment manufactured in large factories, it is not easy to monitor its condition in use. For equipment fabricated in small workshops or by the farmers themselves, it becomes very difficult to ensure that design standards are adhered to especially when the users of equipment are hired labourers on daily wages.

This paper presents the results of an epidemiological study to determine the main causes of injuries among farmers in nine villages in the state of Haryana in Northern India. The study revealed that the largest number of traumatic injuries are caused by fodder cutting machines and threshers. The designs of these machines have been made safer using ergonomics principles. A large number of minor injuries are caused by hand tools.     

Quantitative modelling in cognitive ergonomics: predicting signals passed at danger

Abstract

This paper shows how to combine field observations, experimental data and mathematical modelling to produce quantitative explanations and predictions of complex events in human–machine interaction. As an example, we consider a major railway accident. In 1999, a commuter train passed a red signal near Ladbroke Grove, UK, into the path of an express. We use the Public Inquiry Report, ‘black box’ data, and accident and engineering reports to construct a case history of the accident. We show how to combine field data with mathematical modelling to estimate the probability that the driver observed and identified the state of the signals, and checked their status. Our methodology can explain the SPAD (‘Signal Passed At Danger’), generate recommendations about signal design and placement and provide quantitative guidance for the design of safer railway systems’ speed limits and the location of signals.

Practitioner Summary: Detailed ergonomic analysis of railway signals and rail infrastructure reveals problems of signal identification at this location. A record of driver eye movements measures attention, from which a quantitative model for out signal placement and permitted speeds can be derived. The paper is an example of how to combine field data, basic research and mathematical modelling to solve ergonomic design problems.
