TRUE/FALSE QUESTIONS

1)Crashing is decreasing activity time in a network to reduce time on the critical path so total completion time is reduced.

2. Waterfall software development methodology can accommodate change orders quite easily.
3. When an activity on a PERT network has these time estimates: optimistic = 1, most likely = 3, and pessimistic = 5, the expected activity time is 3.
4. A simple CPM network has three activities, A, B, and C. A is an immediate predecessor of B and of C. B is an immediate predecessor of C. When the activity durations are A=4, B=3, and C=8, the critical path is A-B-C with duration 15.
5. Robust design ensures that small variations in production or assembly do not adversely affect the product.
6. Modular design exists only in tangible products; it makes no sense in services.
7. In the maturity stage of the product life cycle, operations managers will be particularly concerned with adding capacity or enhancing existing capacity to accommodate the increase in product demand.
