Maintenance Process Improvement Model by Integrating LSS and TPM for Service Organisations

Abstract

This paper presents an integrated model to provide guidance and support for those organisations who aim to reach world-class standards in maintenance processes through continual improvement. A strategic model has been developed through conceptual integration of three popular process improvement strategies, which are six sigma, total productive maintenance (TPM) and lean. Lean Six Sigma can operate in parallel with the TPM strategy and will make it easier to understand by shop floor operators. The application of the model has been demonstrated using a case study in maintenance of a fleet of military vehicles. The proposed model is very generic in nature and can be applied to any service organisations with maintenance functions to achieve high process performance and overall equipment effectiveness.
