- In paced assembly lines, cognitive processing is required from assembly workers to perform correct and timely assembly of complex products with varying specifications. This interview study involving 75 industrial assemblers, design- and manufacturing engineers explores how assemblers’ cognitive performance is influenced by multiple factors within the contexts of product design, production setup and assembly. Our results indicate that both positive and negative effects on assemblers’ cognitive performance can stem from task design, timing, physical loading demands, extrinsic motivation factors, teamwork and the assembly “interface” design. Among design- and manufacturing engineers, two mindsets emerged: (i) a product-centred mindset relying on assemblers having sufficient experience, knowledge, and assembly instructions, (ii) an assembler-focused mindset characterised by an iterative and collaborative development process to ensure easy-to-assemble solutions, and avoid errors, delays and costly re-work. Despite organizational differences and conditions between the companies that took part in the study, the results are largely consistent.

Tidskriftsartikel (refereegranskat)abstract
- In manufacturing companies, cognitive processing is required from assembly workers to perform correct and timely assembly of complex products, often with varied specifications and high quality demands. This paper explores assembly operators’ perceptions of cognitive/mental workload to provide a holistic understanding of the work conditions that affect cognitive demands and performance. While the physical loading aspects of assembly work are well known, most empirical literature dealing with cognitive/mental loading in manufacturing tends to examine a few particular aspects, rather than address the issue with a holistic system view. This semi-structured interview study, involving 50 industrial assembly operators from three Swedish companies, explores how assemblers perceive that their cognitive performance and well-being is influenced by a wide variety of factors within the context of mechanical product assembly. The interview transcripts were analysed using a priori coding, followed by bottom-up Thematic Analysis. The results indicate that a variety of systemic effects on assemblers’ cognitive performance can be classified as job demands or resources. Quite often, the absence of a resource mirrors a related demand, and “good assembly conditions”, as described by the interviewees, often re-frame demands as desirable challenges that foster motivation and positive feelings towards the work. The identified demands and resources stem from task design, timing, physical loading, intrinsic and extrinsic motivators, social teamwork and the product’s “interface” design. Despite organisational differences and conditions between the three companies that took part in the study, the results are largely consistent.
