Raw material (Intermediate) Test (8 units/min) 0.C Melting & Forming Injection molding 4 units/ minutes INPUT (Plastic) 10 units Storage Limit) OUTPUT Rejects Other Inputs FIGURE 1. The Example production System 1)- Is the system optimized? 2)- Does the whole system operates expected? 3). What is the bottleneck? 4)- What is % utilization of resources? 5)- What is the capacity of the processes individually and as an integrated system? 6) - Are we wasting time and resources? 7)- What is the throughput time or cycle time? Is it acceptable or could be improved? 8). If we have multitude of problems/wastes, in which area should focus our attention first? what is an estimate of possible improvement is cost, productivity, manufacturing cycle (speed of production), and so on
