Focused Improvement includes all activities that maximize the overall effectiveness of equipment, processes and plant through elimination of losses and improvement of performance. The overall Plant effective (OPE) is calculated as follows: OPE= Availability of Plant x Performance Rate x Quality Rate
Focused improvement -Implementation Steps - Registration of Improvement Topic -Improvement Targets - Implementation Plan for the Topic -Results of Improvement - Focused Improvement Audit
Autonomous maintenance This emphasizes the need for individual workers to carry out routine inspection, oiling, repairs, detection of abnormalities of their own equipments for the purpose of “Protecting their own equipment”.
