Even as production managers spend considerable time on these items, every production unit face three major problems:
- Increasing WIP inventory
- Discrepancies in fixed rate of throughput
- Unmanageable rate of rework and rejections
The reason behind the lack of accuracy often includes the inefficient process of production distribution across lines that reduces the rate of throughput thus increasing inventory that is work-in-progress. Without data to understand each worker’s performance level, the rate of rejections also increase over time.
