6.38. Improving processes incrementally on a continuous basis is: a. Kaizen b. Revolutionary c. Reengineering d. Breakthrough
Revolutionary improvement (b) implies improvement resulting from process redesign rather than corrective action . It is often radical. Reengineering (c) is "the fundamental rethinking and redesign of operating processes and organizational structure, focused on the organization's core competencies to achieve dramatic improvements in organizational performance." Breakthrough (d) improvement is achieved through the use of breakthrough products or processes . The term Kaizen is taken from the Japanese "kai" (change) and "zen" (good), and means "gradual unending improvement." It applies to doing little things better and setting and achieving increasingly higher standards. (a) Answer a is correct. Reference: CSQP Primer , Section VI - 13.

Partially reimbursing the supplier when the product is rejected c. Establishing a flexible schedule of required product quantities and dates d. Providing meaningful and timely quality performance feedback
Solution : It is unlikely that the results of answer b will be positive. The supplier should be involved early not late in product development (answer a is incorrect). Most suppliers want a firm schedule of quantities and dates (answer c is incorrect). Answer d is correct. Reference: CSQP Primer , Section VI - 2/6.
6.29. Kanban concepts include which of the following? a. Delivery of components and products only when needed b. Maximum storage in production areas c. Little production system distress when a machine failure occurs d. Wide applicability to repetitive and non-repetitive production plants
Solution : Item a is usually recognized as key kanban system element. Since in-process inventory is so low, the system stops shortly after any equipment malfunction (answer cis false).

Clearance through Customs on the 15th of the month
Solution : Since the purchase order requires receipt from the 12th to the 15th of the month, any other case is a nonconformance . While answer a means the material is there prior to the required date, most companies would still consider this to be a nonconformance. Answers c and d might or might not be nonconformances. More locational information is needed. Answer b is correct. Reference: CSQP Primer , Section VI - 3.
6.32. Which of the following characterize the muda of waiting? a. Unnecessary operator motions b. Machinery breakdown and uneven schedules c. Excess inventories and overproduction d. Unnecessary transport and overproduction
Solution : The muda of waiting occurs when the operator is idle. Answer b is the best choice . Answer a is the muda of extra motion. Excess inventory , overproduction , and extra transport are stand alone non value added activities. Answer b is correct. Reference: CSQP Primer, Section VI- 20/21.
6.41. What does the following icon represent on a value stream map? lox ox ! a. Buffer stock b. Load leveling c. Schedule box d. Data box

6.2. Commonly used metrics used to assess supplier performance , relative to products or services , are : a. Quality and delivery b. Engineering and support c. Cost and availability d. Design and reliability
Solution : While quality , delivery , cost, service and compliance are measures of supplier performance , the most commonly used (in the opinion of the author) are quality and delivery. In this case, quality is defined as meeting purchase order requirements and specifications, and delivery is the timeliness of the receipt by the customer. If the delivery is early or late compared with a requirement window , the supplier loses points. Answer a is correct. Reference: CSQP Primer , Section VI - 2/3.
6.16. A value stream map would normally provide data on: a. Changeover and cycle times b. The amount of floor space saved c. The current and projected quality levels d. External finished goods inventory

Quarterly status reports and periodic audit results b. A sudden 10% increase in scrap rate c. Critical parts that are needed this week d. On-time deliveries which have dropped dramatically
Solution: Note the key question phrase "routine usage." Quarterly status reports and periodic audit results fall into routine communications . Answers b, c, and d are emergency commun ication items . Answer a is correct. Reference: CSQP Primer , Section VI - 2/3.
6.33. The primary purpose of a dashboard chart is to: a. Provide bar chart comparisons b. Display at least two dial gauges c. Graphically report diverse information d. Report defects found per test hour
Solution: Performance dashboards are so named because they resemble the dial indicators located on the dashboard of an automobile .

6.13. What could happen if the supplier is at too high of a percentage of capacity with a single customer? a. They may be too dependent on the customer b. Quality may deteriorate c. Productivity will decrease d. On time delivery may suffer
Solution: This is a question which the supplier or customer has to ponder from time to time. Having too much business with one source causes a very heavy dependence . Answers b, c, and d are possibilities that may or may not occur. Answer a is a more general and realistic concern. Answer a is correct. Reference: CSQP Primer, Section VI- 4/6 (and logic).
6.7. When comparing breakthrough achievement with Kaizen techniques ,which of the following statements is true? a. Kaizen techniques provide more rapid improvement b. Breakthrough achievement is generally less expensive c. Breakthrough achievement would be used for low tech products d. Kaizen techniques are more easily applied at the floor level
