Change Impact Analysis
I've been spending time within the Service Transition book. Did you know that ITIL V3 has a prescription for performing an impact analysis of a proposed change in the form of 7 "R" questions?
- Who RAISED the change?
- What is the REASON for the change?
- What is the RETURN required from the change?
- What are the RISKS involved in the change?
- What RESOURCES are required to deliver the change?
- Who is RESPONSIBLE for the build, test and implementation of the change?
- What is the RELATIONSHIP between this change and other changes?
Frankly, I would add or clarify a couple of questions:
- What is the COST of the change?" (broken away from the Resources question)
- What is the TIMELINE for implementing the change?
Other than that, I believe that these are meaningful and well-rounded questions, They can serve as a good foundation for a Request for Change template and informed Change Advisory Board discussions.
