A Black Belt collects 20 VOC comments and he finds that the comments are categorized amongst just 2 groups. He wants to use a Pareto to prioritize. Before doing so, what should he do?
OPTIONS
- Group the comments
- Verify the validity of the comments
- Collect some more comments as 2 groups is too few for a Pareto
- Irrespective, should plot a Pareto
ANSWER
Verify the validity of the comments
EXPLANATION
Now this is a bit confusing. Except for option d which is not a serious consideration, the Black Belt may decide to do either a b or c. Most Black Belts though would know that customer comments once received need to be verified first.
