1. In an assembly operation with 3 components whose individual service level to the assembly line is 90%, the overall service assuming no issues in assembly itself will be:
   1. 90%
   2. 81%
   3. 72%
2. The scientific way to reduce cycle time without sacrificing TH is to:
   1. Reduce WIP but not below Critical WIP.
   2. Implement a six sigma program
   3. Implement a lean program
   4. Reduce WIP below Critical WIP.
3. Assume you are on the marginal case curveif the desired throughput for the operation is a minimum of 450 units and customers need the product in no longer than 3 days, you could deliver these results by:
   1. Reduce WIP to 100 units
   2. Reducing WIP to 1500 units
   3. Increasing WIP to 2800 units
   4. None of the above
