B.Identify and validate root causes
C.Develop a plan for controlling the implemented solutions
D.None of the above

3.    The main purpose of the Improve Phase is to:

A.Develop a SIPOC map
B.Put plans in place to maintain the gains made
C.Identify the critical measures of the process
D.Identify the creative solutions that solve the validated root causes

4.    Validation of root cause is made only when which standard(s) is met:

A.There is a statistically significant relationship between the suspected root cause and the effect.
B.The data is normal
C.Knowledge of the process corroborates this causal relationship.
D. Both A and C above

5.    The main purpose of the analyze phase is to:
