Reduce interruptions. Any issue that causes long delays and increases the cycle time for a critical business process is an interruption. The production of an important order can, for example, be stopped by an order from a far less valuable customer request--one that must be rushed because it has been delayed. Similarly, anyone working amidst a critical business process can be interrupted by a phone call that could have been handled by someone else. The main principle is that everything should be done to allow uninterrupted operation of the critical business processes and let others handle interruptions.
I am working on implementing OEE in one of our machines that makes centertubes for automotive oil filters. The steel is rolled and each part number has specific diameter and length. However, the run-rates vary for each part numbers. I am somewhat able to calculate Takt time for each part number based on the standard run-rate. However, the problem for me is to determine Ideal Cycle Time. The machine can run as fast as 65 PPM for one part number while it runs as slow as 13 PPM for some other part number. In this case, what would be the optimal way to calculate Ideal Cycle Time for each part numbers? As you know, Ideal Cycle time is required to calculate Performance Metric of OEE.
