Short-Term Physiological Strain and Recovery among Employees Working with Agile and Lean Methods in Software and Embedded ICT Systems

Abstract

Agile work practices have become popular. Although they hold great promise regarding well-being at work, systematic scientific research on this connection is scarce. This article aims to capture the current situation by measuring the state of mental workload using physiological indicators and by comparing high and low perceived agile work. Is the agile way of working associated with well-being at work? Three software teams and four embedded development teams were used in the different phases of applying agile methods. We conducted a baseline survey on perceived agile work in the team and carried out physiological measurements three times in a working period. Repeated-measure procedure was used to analyze the effects. The results provide evidence that agile work could even out workload during a working period, i.e. maintain sustainable pace. The results of the low agile work were in line with the assumption that work will accumulate at the end of the period because of loose planning and a lack of frequent checking. Therefore, workers also felt more strain from the pressure of deadlines.
