1. The goals of the define phase are to know, understand, and become intimate with your business processes.
a. True
b. False
2. The define phase is accomplished using a series of proven tools such as process mapping, process walkthroughs, and failure modes and effects analysis.
a. True
b. False
3. Understanding process variation and its genesis includes acquiring all process documentation and data, developing process maps and value stream maps at cascading levels, as needed, to understand and measure the process, performing a series of process walkthroughs to verify and valid ate the process and value stream maps, performing a FMEA to better understand each process work center and step and to measure the risk associated with each process element.
a. True
b. False
4. A defect is any error that results in customer dissatisfaction or downstream employee rework. As a level of quality, Six Sigma measures the number of defects per opportunity, or DPO. Defects per opportunity (DPO) consists of total defects divided by total opportunities.
a. True
b. False
5. If there are 28 defect opportunities, 100 units processed, and 3 defects made, the DPO is 0.00107 and the resulting yield is 99.893%.
a. True
b. False
6. Rolled throughput yield (RTY) is the variability we are most used to dealing with, and it comes from our everyday working processes, the human, technical, and procedural factors that contribute to variability.
a. True
b. False
7. Rolled throughput yield (RTY) is the probability that a single unit can pass through a series of process steps free of defects. This means that RTY takes into account rework, which makes it a better indicator of the nature of the process.
a. True
b. False
8. Process variability is a better indicator of the nature of the process because it shows the extent of bidden factory, indicates where in the process steps needed to be improved, can be used to plan for the effect of hidden factory while working to improve the process.
a. True
b. False
9. FMEA is a unique kind of process mapping that lists and relates all of the elements and actions required to bring a product/service from required inputs to delivery to the customer.
a. True
b. False
10. Value stream mapping (VSM) is a systematic evaluation procedure used to identify, analyze, prioritize, and document potential failure modes, their effects on a system, product, and process, the failure causes, the controls used to mitigate the causes or modes, a measurable level of risk, potential corrective actions.
a. True
b. False
