98.	A process improvement team has employed a fishbone diagram to identify the potential root causes of a problem. What should be the team's next step toward resolving the issue?

	A	Develop a corrective action plan to systematically address and resolve each of the root causes that have been identified.
	B	Add each of the identified root causes to the control plan of the project to ensure that they are tracked over time.
	C	Identify the person responsible for each of the root causes identified and revise their standard work to add an error-proofing step.
	D	Employ data to validate that the potential root causes are in fact true causes of the problem.
	E	In the Improve Phase, work with the team to develop a specific improvement plan for each of the identified root causes that has a sigma level lower than 6.
