This study is a process evaluation of a trial examining the effects of an organizational intervention (Productivity Measurement and Enhancement System or ProMES) on employee stress. The aims were to explore the implementation process and fidelity to the intervention guidelines, examine the influence of contextual factors (hindrances and facilitators) and explore participants' experience of working with ProMES. We used the UK Medical Research Council (MRC) guidance to guide the process evaluation. The recruitment, reach and dose delivered were satisfactory and participation high. The employees felt ProMES clarified priorities, gave control and increased participation in decision-making. However, difficulty in obtaining statistical productivity data from the central administration office (a central feature of the intervention) hindered full implementation and regular feedback meetings. Staffing shortages interfered with the implementation process, while having seven design teams and one consultant prevented all occupational groups from working simultaneously. A detailed examination of access to necessary organizational data should be undertaken before implementing ProMES. We recommend a better introduction for new employees, more work on design and packaging and giving employees more training in how to use the software program. The study contributes to our understanding of process evaluations in research into organizational stress management interventions.
