Certified Six Sigma Black Belt Exam Project Identification and Selection 3

Question 1

A Black Belt discovers that a process generates 15,000 defects per million opportunities. Without improvement, what is the approximate sigma level of this process?

Accepted Answer

3.6 sigma

Answer

15,000 DPMO corresponds to approximately 3.6 sigma (short-term), which helps quantify the magnitude of the improvement opportunity during project selection.

Question 2

Which of the following is the BEST reason to avoid selecting a Six Sigma project that requires a fundamental redesign of a core business system?

Accepted Answer

DMAIC works best when a process already exists and needs optimization

Answer

DMAIC is designed to improve existing processes; projects requiring complete redesign are better suited for DMADV (Design for Six Sigma).

Question 3

When prioritizing projects using a risk-adjusted NPV, what factor is incorporated that standard NPV does not account for?

Accepted Answer

Probability of project success

Answer

Risk-adjusted NPV multiplies the expected NPV by the probability of success, accounting for project uncertainty during selection.

Question 4

An organization's voice of the customer (VOC) data shows that delivery speed is the top complaint. Which project selection approach would BEST translate this VOC input into a measurable project goal?

Accepted Answer

Translate VOC into a Critical to Quality (CTQ) characteristic with a specific target

Answer

VOC data must be translated into measurable CTQ characteristics with specific targets before it can drive a meaningful Six Sigma project scope.

Question 5

A champion is reviewing potential projects and finds one with a high Cost of Poor Quality (COPQ) but low strategic alignment. How should this project be handled?

Accepted Answer

Deprioritize it and look for projects that combine financial impact with strategic alignment

Answer

Best-practice project selection balances both financial impact (COPQ) and strategic alignment; a project strong on only one dimension is typically deprioritized.
