Integrating ergonomics into the product development process

A cross-sectional case study was performed in a large company producing electro-mechanical products for industrial application. The purpose was to elucidate conditions and strategies for integrating ergonomics into the product development process thereby preventing ergonomic problems at the time of manufacture of new products. In reality the product development process is not a rational problem solving process and does not proceed in a sequential manner as described in engineering models. Instead it is a complex organizational process involving uncertainties, iterative elements and negotiation between key actors. Design and production engineers have a great influence on ergonomics in manufacturing departments. Ergonomics considerations are partly taken into account by production engineers but not as a part of standard operating procedures. There is a number of differences between design and production engineers regarding information sources in problem solving, communication pattern, perception of ergonomics, motivation and requests to support tools and methods. These differences and the social and organizational context of the development process must be taken into account when considering strategies to the integration of ergonomics. Relevance to industry n nErgonomics considerations at the stage of product development in industry is a major strategy for prevention of work-related injuries and illnesses among employees at the time of manufacture of new products. This study elucidates some important conditions and possibilities for integrating such considerations during the product development process.

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.

Workspace design: a case study applying participatory design principles of healthy workplaces in an industrial setting

The Danish workspace design (WSD) research program is aimed to develop and trial a potential new concept for ergonomists and other workplace consultants who are to engage in socio-technical design processes. The objective of this paper is to report on the trial of the workspace design concept in a case involving the design and implementation of a new mixing technology in an industrial plant. The case showed how the WSD concept can contribute to an engineering design process. The WSD team took the role as workspace designer and by the participatory workshops achieved an impact on the technology project. In the role as workspace designer, it was important for the WSD team to make sure that the achievements in the workshops were ‘transmitted’ to and sustained in the ordinary engineering design process. In this case, it turned out that the artefacts such as a layout game board and documents with compilations of ideas and requirements from use scenarios served as appropriate transmitter devices or inscriptions.

Integrating ergonomics into engineering design: the role of objects.

The objective of this study was to explore the role of objects in integrating ergonomic knowledge in engineering design processes. An engineering design case was analyzed using the theoretical concepts of boundary objects and intermediary objects: Boundary objects facilitate collaboration between different knowledge domains, while the aim of an intermediary object is to circulate knowledge and thus produce a distant effect. Adjustable layout drawings served as boundary objects and had a positive impact on the dialog between an ergonomist and designers. An ergonomic guideline document was identified as an intermediary object. However, when the ergonomic guidelines were circulated in the design process, only some of the guidelines were transferred to the design of the sterile processing plant. Based on these findings, recommendations for working with objects in design processes are included.

Participatory ergonomics simulation of hospital work systems: The influence of simulation media on simulation outcome

Current application of work system simulation in participatory ergonomics (PE) design includes a variety of different simulation media. However, the actual influence of the media attributes on the simulation outcome has received less attention. This study investigates two simulation media: full-scale mock-ups and table-top models. The aim is to compare, how the media attributes of fidelity and affordance influence the ergonomics identification and evaluation in PE design of hospital work systems. The results illustrate, how the full-scale mock-ups high fidelity of room layout and affordance of tool operation support ergonomics identification and evaluation related to the work system entities space and technologies & tools. The table-top models high fidelity of function relations and affordance of a helicopter view support ergonomics identification and evaluation related to the entity organization. Furthermore, the study addresses the form of the identified and evaluated conditions, being either identified challenges or tangible design criteria.

LCA Experiences in Danish Industry: Results of a Survey

A study has been performed on Danish industry’s experiences with LCA. Twenty-six enterprises from different sectors conpleted a questionnaire. The enterprises are still in an adoption and learning phase, and experiences with full-blown LCA’s are sparse. Expectations of future market pressure to supply more environmentally friendly products is the most important incentive for the enterprises to engage in LCA activities. This pressure, however, has not yet emerged and the enterprises have not achieved the expected competitive advantages. LCA work has revealed new environmental aspects of the products with subsequent new priorities in the environmental efforts. Only a few enterprises have built up in-house LCA competence, whereas consultants are heavily involved in LCA work. In large enterprises, LCA work is predominantly carried out by environmental staff members, but the product development staff is also involved. The nature of the co-operation and distribution of roles between these two actors is not clear, and should therefore be studied further.

Learning processes across knowledge domains

Purpose – The purpose of this paper is to shed light on the problematics of learning across knowledge boundaries in organizational settings. The paper specifically explores learning processes that emerge, when a new knowledge domain is introduced into an existing organizational practice with the aim of creating a new combined practice. Design/methodology/approach – A case study was carried out as a “natural experiment” in an engineering consultancy, where emerging initiatives to integrate the newly acquired competencies into the existing practice were explored. A theoretical framework informed by selected perspectives on learning processes and boundary processes was applied on three illustrative vignettes to illuminate learning potentials and shortcomings in boundary processes. Findings – In the engineering consultancy, it was found that while learning did occur in the consultancy organization, it remained discrete in ‘pockets’ of learning; mainly at an individual level, at project level or as domain-spec...

User-driven innovation of an outpatient department

This paper presents experiences from a user-driven innovation process of an outpatient department in a hospital. The mixing of methods from user-driven innovation and participatory design contributed to develop an innovative concept of the spatial and organizational design of an outpatient department in a hospital. Design games and tabletop simulation seem to be powerful tools in facilitating such a participatory process.

Intermediary objects in the workspace design process: means of experience transfer in the offshore sector

The aim of this paper is to discuss the use of intermediary objects in the workspace design process of offshore accommodations module. The integration of ergonomics in the design process can lead to better work conditions, more effectiveness in the work process and less health and safety issues. Moreover, it is more efficient in terms of cost if ergonomics is considered from the initial phases of the project, as the potential costs of the redesign, the possible losses and the down-time in the operation of the platform would be more increased. The goal, then, is to discuss the integration of ergonomics and users involvement in the design process of accommodations modules, focusing on the transfer of information from reference situations by the use of intermediary objects during the process. In this paper we will present two tools developed to be used as intermediary object(s) aiming at transferring the experience from the use to the design in the specific field of offshore accommodations module.

A framework of knowledge creation processes in participatory simulation of hospital work systems

Abstract Participatory simulation (PS) is a method to involve workers in simulating and designing their own future work system. Existing PS studies have focused on analysing the outcome, and minimal attention has been devoted to the process of creating this outcome. In order to study this process, we suggest applying a knowledge creation perspective. The aim of this study was to develop a framework describing the process of how ergonomics knowledge is created in PS. Video recordings from three projects applying PS of hospital work systems constituted the foundation of process mining analysis. The analysis resulted in a framework revealing the sources of ergonomics knowledge creation as sequential relationships between the activities of simulation participants sharing work experiences; experimenting with scenarios; and reflecting on ergonomics consequences. We argue that this framework reveals the hidden steps of PS that are essential when planning and facilitating PS that aims at designing work systems. Practitioner Summary: When facilitating participatory simulation (PS) in work system design, achieving an understanding of the PS process is essential. By applying a knowledge creation perspective and process mining, we investigated the knowledge-creating activities constituting the PS process. The analysis resulted in a framework of the knowledge-creating process in PS.
