Kendra Little walks through a fairly simple but very useful change management template:
Good Change Management makes your team smarter. When you change things a lot, things are going to break sometimes. If you’ve done a good change request, you’ll know exactly what to do when something breaks: either you’ll roll the change back, or have a Plan B to execute on. Good change requests also mean that business owners understand the risks of the changes and have approved them, and that teammates have reviewed them: good changes aren’t done in isolation.
Change Management isn’t just for IT. If you’re a developer who deploys changes to production, you need this as well.
Change management doesn’t need to be a complex endeavor. It should, however, give you enough information to save yourself if things get crazy.
