Purpose: The main aim of the research undertaken within this article is to identify the factors that are important for the successful implementation of ergonomic projects, which can be used to effectively manage such projects. Design/methodology/approach: As part of the research undertaken in this article, a literature review was carried out on the success factors of ergonomic projects. Then they were assessed using an expert opinion survey method in order to establish their importance according to the experts involved (participants of the ergonomic commissions operating in production companies). The results of the research can be used to develop scenarios for the implementation of such projects, which was shown on the example of an ergonomic project undertaken in a selected company. Findings: The result of the research is identification of the success factors of an ergonomic project presented in five categories: factors related to the implementation of projects in the enterprise, factors related to stakeholder requirements, factors related to the specificity of ergonomic assessment, factors related to the internal environment of the enterprise, factors related to the external environment of the enterprise. Taking into account the factors assessed by experts as the most important may contribute to their effective shaping in order to conduct an ergonomic project with success, as shown in a practical example. Research limitations/implications: The presented findings are limited by showing them only on one practical example. The further direction of the research development may be the presentation of decision models for managing ergonomic projects based on the identified success factors. Practical implications: The results of the conducted research can be used in practice in the implementation of ergonomic projects in various production companies. Originality/value: This article presents a new approach to the identification of success factors of ergonomic projects and presents the possibilities of including them in the implementation of ergonomic projects in manufacturing companies.

The study aimed to conduct an ergonomic intervention on a conventional line (CL) in a semiconductor factory in Malaysia, an industrially developing country (IDC), to improve workers’ occupational health and safety (OHS). Low-cost and simple (LCS) ergonomics methods were used (suitable for IDCs), e.g., subjective assessment, direct observation, use of archival data and assessment of noise. It was found that workers were facing noise irritation, neck and back pains and headache in the various processes in the CL. LCS ergonomic interventions to rectify the problems included installing noise insulating covers, providing earplugs, installing elevated platforms, slanting visual display terminals and installing extra exhaust fans. The interventions cost less than 3 000 USD but they significantly improved workers’ OHS, which directly correlated with an improvement in working conditions and job satisfaction. The findings are useful in solving OHS problems in electronics industries in IDCs as they share similar manufacturing processes, problems and limitations.

This special issue of the International Journal of Occupational Safety and Ergonomics (JOSE) reports the results from an extensive multinational and multidisciplinary collaborative investigation of the impacts on visual display terminal (VDT) work of musculoskeletal, visual, ergonomic, and psychosocial factors. For brevity, this effort has been referred to as the MEPS project musculoskeletal-eyestrain-psychosocial-stress). This paper lays out the basic methodological structure of the study. The study was conducted in 4 countries utilizing VDT data entry workers as the primary subject population. A battery of objective and subject assessment measures, including muscle load, visual function, physical and visual strain, postural, ergonomic and psychosocial factors, were assessed at 3 different points in time. A pre-test was given prior to an ergonomic intervention. Two posttests were given 1 month and 1 year after the ergonomic intervention.

The United States MEPS (musculoskeletal-eyestrain-psychosocial-stress) study consisted of 1 group of 28 female data entry operators. The intervention was in 3 parts: workstation redesign (including advanced ergonomic chairs, motorized adjustable workstations, advanced adjustable keyboards, adjustable copyholders, adjustable footrests, monitor support surfaces) and ergonomic training/coaching and corrective lenses. After the intervention, statistically significant reductions in physical signs (trigger points, neck and shoulder mobility), subjective reports of intensity and frequency of musculoskeletal pain, and subjective reports of visual problems were observed. Static load during the work sample, as assessed by experts, improved after the intervention as did measured postural angles of head and trunk and subjective assessment of users of ergonomic characteristics of the workplaces. For all of these measures, improvements observed 1 month after intervention were also observed in the 1-year follow-up. Trapezius load, as assessed by electromyography (EMG), decreased after intervention, but then increased in the follow-up. The increase was interpreted as a calibration problem.

A group of routine data entry operators (female) was included in the Polish MEPS (musculoskeletal-eyestrain-psychosocial-stress) study. Before the intervention, ergonomic assessment revealed improper working conditions such as inadequate lighting, uncomfortable chairs, and lack of forearm and wrist support while medical examination revealed that trapezius muscle load along with upper arm, head and back angles were higher than advisable. Subjects complained about neck and shoulder pain, visual problems, and psychosocial conditions. The ergonomic intervention included installation of new luminaires and Venetian blinds, new chairs, repair of ventilators, and optometric corrections. The results after the intervention showed mainly improvement in chair comfort, lighting conditions, visual strain, and sitting posture. However, financial limitations did not allow satisfactory completion of the intervention leading to a mixed interpretation of the results.

The MEPS (musculoskeletal—eyestrain—psychosocial—stress) study involved an extensive degree of multidisciplinary and multicultural cooperation. The objective was to examine the effects of multiple ergonomic interventions on visual, musculoskeletal, postural, and psychosocial outcomes amongst operators of visual display terminals (VDTs). The inherent complexity of a comprehensive ergonomic investigation requires participation of researchers from a variety of disciplines, as well as comparisons among populations with different geographical and cultural backgrounds. The design and execution of the resulting research protocol presents a number of challenges. This paper discusses the advantages and pitfalls associated with multidisciplinary multinational cooperation. Advantages include the necessity for development of a common language and perspective providing a basis for future collaboration. Pitfalls include logistic and coordination difficulties associated with conducting standardized procedures in different locations, as well as the inherent potential for professional conflict. It is argued that such pitfalls ought to be understood and integrated into the project planning process.

The study aimed at reducing the occupational health and safety problems faced by the manual component insertion operators. Subjective and objective assessments, and direct observations were made in the printed circuit assembly factory. Simple and low-cost ergonomic interventions were implemented, that is, repairing chairs, reducing high workloads, assigning operators to a maximum of 2 workstations, confining machines that emitted bad smell and much noise, and providing finger work aids. The results of the interventions were reductions in operators’ work discomforts, that is, chair discomfort (by 90%), high work stress, and discomfort due to frequent change of their workstations. Their health hazards were also eliminated, that is, inhalation of toxic fumes, exposure to too much noise, and pain due to pressing sharp components.
