3. Which of the following statements about small-lot production is false?
The lower inventory levels resulting from small-lot production hide problems in the production process
.
4. The concept of flexible resources ________.
includes multifunctional workers
5. American workers implementing lean prefer ________.
the fast pace of kaizen blitzes
6. Analyzing process flow and eliminating waste is referred to as ________. value stream mapping
7. The benefits of lean production include all of the following except reduced ________.
product variety
8. The authority for a worker to stop the production line when quality problems are encountered is known as ________
. Jidoka
9. How many kanbans should circulate between two workstations if demand is 1,000 units per hour, lead time is 30 minutes, container sizes are 50, and the company uses a safety factor of 10%? Solution: Kanban (N) = [1,000 × 0.5 + (0.1 × 1,000 × 0.5] / 50 = 11
10. According to one of the suggested videos provided in the course material, a key concept in lean is waste, which can be defined as ________. anything that does not add value to the customer
11. Leaning a supply chain ________ flow through a series of suppliers. pulls a smooth
12. Supplier networks ________ require imperatively that the source of supply be located close to the customer 13. In ________ production systems, items are produced only when they are demanded by customers while ________ systems rely on predetermined production schedules often generated by computerized systems. pull | push
14. One of the principles on which the SMED (single-minute exchange of dies) system is based is that it ________. streamlines all aspects of setup
15. How many kanbans should circulate between two workstations if demand is 500 units per hour, lead time is 20 minutes, container sizes are 50, and the company uses a safety factor of 20%? Solution: Kanban (N) = [500 × 0.33 + (0.2 × 500 × 0.33] / 50 = 4
1. The estimated mean time for an activity with a most likely time (m) equal to 14 days, the optimistic time (a) equal to 8 days, and the pessimistic time (b) equal to 20 days is ________ days. The estimated variance of this activity is ________.
Solution: t = (a + 4m + b) / 6 = (8 + (4)(14) + 20) / 6 = 14 days | σ2 = [(b – a) / 6]2 = [(20 – 8) / 6]2 = 4
2. Which of the following is not used to calculate probabilistic time estimates? Least likely time
3. Which of the following is not one of the basic steps involved in developing a schedule? Least likely time
4. Which of the following is not one of the basic steps involved in developing a schedule? Identify the project cost
5. A(n) ________ provides a common understanding of and justification for a project and what constitutes project success. project scope
6. Which of the following statements is true? Diversity among project team members brings different views, experiences, and values.
7. For activities on a project’s critical path, ________. earliest start time (ES) equals latest start time (LS)
8. A(n) ________ breaks down a project into its major components, which are further divided into subcomponents, activities, and, finally, individual tasks. work breakdown structure (WBS)
9. Given that an activity's normal time and cost are 6 days and $500, respectively, and its crash time and cost are 3 days and $800, respectively, what is the activity's crash cost per day?
Solution: Cost per day = (Crash cost – Normal cost) / (Normal time – Crash time) = ($800 – $500) / (6 days – 3 days) = $300 / 3 = $100
10. According to one of the suggested videos provided in the course material, before building your team, consider the ________ you will need. skills and know-how
11. The estimated mean time for an activity with a most likely time (m) equal to 9 days, the optimistic time (a) equal to 3 days, and the pessimistic time (b) equal to 15 days is ________ days. The estimated variance of this activity is ________. Solution: t = (a + 4m + b) / 6 = (3 + (4)(9) + 15) / 6 = 9 days | σ2 = [(b – a) / 6]2 = [(15 – 3) / 6]2 = 4
12. The project manager can develop a ________ which shows who in the organization is responsible for doing the work in the project. responsibility assignment matrix
13. The slack time for an activity can be computed as ________.
latest start time (LS) – earliest start time (ES)
14. For activities on a project’s critical path, ________. earliest start time (ES) equals latest start time (LS)
15. Given that an activity's normal time and cost are 6 days and $500, respectively, and its crash time and cost are 3 days and $800, respectively, what is the activity's crash cost per day? Solution: Cost per day = (Crash cost – Normal cost) / (Normal time – Crash time) = ($800 – $500) / (6 days – 3 days) = $300 / 3 = $100
