Slide 6 Part I 1. If a supply-constrained business increases process capacity, it will not  make more money unless it also increases the demand rate, through for  example, an advertising campaign  2. The bottleneck(s) of a process always has(ve) the highest utilization of all  resources  3. Process utilization is always less than or equal to implied utilization   4. It is not possible to increase the average labor utilization without laying  off workers 5. If a process has an average inventory of 10 units and cycle time of 12  minutes, then average flow time is 2 hours F T T F T

Slide 7 Part I 6. A bottleneck in a process must always have a 100% utilization  7. For most processes, the average flow time of flow units is equal to the  cycle time of the process  8. Per unit inventory cost always increases when inventory turns increases.  9. Increasing the capacity of a non-bottleneck resource may increase process  capacity when the process is demand-constrained. 10. Cycle inventory is used to smooth the seasonality of the supply stream.  F F F F F
