Abstract: The TPM measure OEE is introduced as an indicator of plant effectiveness to be used in conjunction with the Six Sigma DMAIC improvement methodology. Facilitating theory development through practical application, an Action Research methodology is adopted for the project. Completory is the introduction of a triangulated project approach utilising both objective, quantitative methods for data analysis and problem solving as well as subjective, qualitative methods for dealing with the personnel elements of Six Sigma projects. Findings suggest the approach adopted was successful, achieving a near 50% improvement in the OEE over a 12-week period.

Keywords: lean six sigma; total productive maintenance; TPM; overall equipment effectiveness; overall equipment efficiency; OEE; Pareto analysis; DMAIC; key performance indicators; KPI; action research; quality improvement.
