It is difficult to see how a traditional ITIL Change Management process would work with Scrum.
Some of the reasons for this include:
* In Scrum we look to have a potentially releasable increment at the end of each sprint and we typically _release frequently_. It is hard to see how this can be done in combination with an ITIL process unless it has been streamlined and made very responsive.
* In Scrum the Product Owner is responsible for prioritising the product backlog and often decides when releases will happen. This responsibility will typically clash with the roles and responsibilities of the ITIL process (such as the CAB).
* In Scrum we look to have everyone required to deliver a release in the Scrum Team. If there are dependencies on people outside the team that are involved in the change management process then this disrupts one of the core aspects of Scrum.
