1. When is DMAIC a poor choice for a problem?
- A.Defects cost a lot each year
- B.The cause and fix are known
- C.The root cause is unknown
- D.The process has data to study
Answer: B. DMAIC suits problems with an unknown cause and measurable data. If the solution is obvious, a just-do-it fix or a short kaizen is faster.
2. A steering team ranks candidate projects. Which factor matters most in selecting one?
- A.How many people it involves
- B.How new the analysis tools are
- C.Which department asked first
- D.Business benefit against effort
Answer: D. Project selection weighs expected savings, customer impact and strategic fit against cost, time and risk, often in a prioritization matrix.
3. A purchase-to-pay process passes through purchasing, receiving and accounts payable. What challenge does this create?
- A.No one function owns the flow
- B.Data cannot be collected
- C.The process has no customer
- D.Every step adds customer value
Answer: A. Processes that cross departments suffer hand-off delays and finger-pointing because each function optimizes its own part. A process owner for the whole flow helps.
4. Which item marks a process boundary in a project's scope?
- A.The team's meeting time
- B.The sponsor's job title and level
- C.Its first and last steps
- D.The project budget
Answer: C. Process boundaries are the start and end points that define what the project will and will not change. SIPOC is a common way to set them.
5. A hospital compares its patient discharge process with a hotel's checkout process. What type of benchmarking is this?
- A.Internal process
- B.Collaborative
- C.Best practice
- D.Competitive
Answer: C. Best practice benchmarking looks outside the industry at an organization that excels at a similar function. Competitive benchmarking compares with direct rivals.
6. Several hospitals in a network agree to share their infection data to learn from one another. Which benchmarking type is this?
- A.Collaborative
- B.Best practice
- C.Reverse engineering
- D.Competitive

- A.A government regulator
- B.The end buyer of the product
- C.The shipping carrier
- D.The packing team downstream

8. A SIPOC places which element immediately before the process steps?
- A.Controls
- B.Inputs
- C.Outputs
- D.Customers
Answer: B. SIPOC lists suppliers, inputs, process, outputs and customers in that order. Inputs feed the high-level process steps; outputs leave them.
9. A team wants rich, detailed opinions from eight key customers on why they cancelled. Which method fits best?
- A.A check sheet
- B.One-to-one interviews
- C.A mass email survey
- D.A warranty data review
Answer: B. Interviews allow probing follow-up questions with a small number of people. Large surveys give breadth but little depth on reasons.
10. A survey asks: "How satisfied are you with our fast and friendly service?" What is wrong with it?
- A.It is too short to be useful
- B.It names the service
- C.It uses a rating scale

Answer: D. This is a double-barreled question: a customer may find service fast but not friendly. Each question should cover one idea, worded without bias.
