The types of changes and how we determine the impact stays largely the same, assuming a healthy and mature process exists. However change execution will be different because of automation and the advent of agile ways of working such as the afore mentioned DevOps teams. Some process maturity is needed to get started in the cloud, so start with determining process maturity and determine what changes need to be made to ‘Run in Control’.
Important activities for governance are communicating about RACI models for future and transitional modes of operation. Report on the maturity gap and activities related to improving it up to ‘Run in Control’ level and allow for specific changes in the process if the situation calls for it through a dispensation route.
The CCoE helps with determining the impact of High Impact changes. The Enterprise Architect may be involved as well. The CCoE helps with providing tooling to automate Standard Changes.
