Exploring a holistic perspective on production system improvement

Purpose – The purpose of this paper is to examine how holistic improvement work can be organized and what challenges can be observed in the process of adopting a holistic perspective on production system improvement. Design/methodology/approach – A qualitative case study and a questionnaire have been carried out. Data for the case study has been collected through semi-structured interviews, archived documents and participatory observations. The questionnaire was done in order to increase the generalizability of the findings from the case study and further validate the conclusions. Findings – The improvement work at the case company is organized as a continuous improvement approach in a Lean Production system in the form of a company-specific production system (XPS), in which two other improvement approaches are incorporated. Some of the identified challenges are: the establishment of a holistic perspective on improvement opportunities; the development of a process to update the production strategy; the continuous update of the Operational Management System during the XPS implementation; aggregating measures for the improvement work and measuring the effect of improvement work. Research limitations/implications – As the current case study is limited to one case company, future research is interested in expanding to other production systems contexts for further validation. Originality/value – The present study offers an increased understanding of the integration difficulties of improvement work that many production companies face regarding operational effectiveness, and based on the findings, some implications for management are presented.
