Couldnt see if this was suggested before - In reality, machine/process failures and slowdowns would occur, the fixes would include preventive maintenance, machine replacement after deterioration and on bottleneck processes further improvement work (maybe by your AOE clipboard guys)
The six big losses: Planned maintenance, unplanned maintenance (breakdowns), process changeovers (from batch to batch e.g. different cars with different engine types, electronics)
Speed losses due to deterioration and idling
Defects
Defects incurred whilst starting up (e.g. changing part types)
An OEE (overall equipment effectiveness) score of 100% means you are manufacturing Defect free Parts, as fast as possible, with no Stop Time. In the language of OEE that means 100% Quality (only Good Parts), 100% Performance (as fast as possible), and 100% Availability (no Stop Time).
