Abstract
  • Lean manufacturing, or more generally continuous improvement (CI), has been the methodology behind significant improvements in quality, work in process inventory reductions, lead time reduction and cost reduction while conversely being associated with failed implementations and occasionally with unpopular work practices. This research focused on promoting understanding of CI methodology and practices while investigating the socio-cultural factors that promote short-term CI project success. To investigate the relationships involved, a working model for short-term CI project effectiveness was developed and used to create surveys that were distributed to hospital employees who had completed a CI training course and had participated in at least one short-term CI project. Open-ended questions and an investigation of a set of CI project documents (A3 reports) provided additional insight into the study and a more holistic perspective of the effectiveness of short-term CI projects and CI programs. Based on the findings from this study, affective commitment to change or the perception of the need for the specific change was the most significant predictor of three measures of project success; impact on area, attitude and task knowledge, skills and attitudes (task KSA). Team autonomy or the amount of control over project activities that is given to project team members, was also a significant predictor of both task KSA and impact on area. Results from the other two data sets support the need for further investigation of additional factors as predictors of short-term CI project success. The results suggested that the projects had a positive impact to both social and technical systems in the hospital where the research was conducted.
