WEEK 9 SELF-TEST QUESTIONS WITH VALID
SOLUTIONS
True or False: The impact/effort matrix is a simple five-square matrix that takes each
solution and places it in the quadrant that best reflects the impact expected and the effort
required if that solution were chosen. - ✔✔False, it's a four-square matrix
Which of the following is an objective of the Improve Phase?
a) execute full-scale implementation
b) confirm scope, goals and objectives of a project
c) conduct benchmarking
d) find the critical Xs (root causes) - ✔✔a) execute full-scale implementation
Why are solutions typically piloted prior to full implementation?
a) to validate improvements and minimize risks and costs
b) to develop the project charter
c) to finalize the data collection plan
d) to perform linear regression on the Xs vs. the Ys - ✔✔a) to validate improvements and
minimize risks and costs
A DMAIC team is struggling to reach consensus agreement on which improvement is best
to deliver the desired project results. A good tool for this situation cou ld be a
______________.
a) solution selection matrix
b) hypothesis test
c) regression analysis
d) value stream map - ✔✔ a) solution selection matrix - solutions are ranked by the team
according to the agreed criteria
True or False: Given the nature of both tools, the solution selection matrix is a much
simpler tool compared to the impact/effort matrix. - ✔✔False
, The purpose of the Six Sigma Improve Phase is to _________________________.
a) generate and test possible solutions
b) select the best solutions
c) design an implementation plan
d) a and b
e) a, b, and c - ✔✔e) a, b, and c
The project leader wants to ensure her improvements are going to be effective and will
deliver the desired results. Which of the following is appropriate for this situation?
a) do a capability analysis
b) conduct a pilot study
c) extract and extend numbers from the analyze phase
d) none of the above - ✔✔ b) conduct a pilot study
True or False: The solution prioritization matrix is a more complex matrix where the
solutions are ranked according to the team-agreed criteria. - ✔✔True
True or False: Lean manufacturing tools are often used in the Improve Phase of a Six
Sigma project. - ✔✔True - to reduce waste and improve the flow in the process.
True or False: Pilot studies are most useful in DFSS projects. - ✔✔False
Vickie's boss is not sure she should be running a project because he is concerned that the
benefits of new business will not outweigh the costs. Which of the following measures
may be useful in evaluating this decision?
a) expected profit
b) expected value
c) costs
