Rated capacity of an equipment is often an obstacle in releasing more capacity.
TOC advocates that capacity of the constraint resource should be exploited to the full. If the constraint resource happens to be an equipment on the shop floor, we should increase its output as much as we can.
However, in several TOC implementations across the world, I have noticed that the teams try to reach up to the rated capacity of the equipment and stop their efforts after that. Very few companies have tried exploiting it beyond the rated capacity. Why is it so?
Our analysis indicates that rated capacity becomes an obstacle to the capacity release process in many cases. The teams have been conditioned over time to see capacity as a finite resource, limited by the equipment capacity rating.
A few teams have used TOC’s Thinking Processes to overcome this obstacle and release the capacity of their constrained equipment way beyond its rated capacity.
