Assume that you are a reporting and analytics team manager and have successfully rolled out the perfect operational reporting platform that multiple departments will use. The process was smooth - the Requirements Document was grand, and UAT testing was a success. After enjoying a week or two basking in the project's completion, the inevitable happens - change requests start coming in from people not involved in the rollout or users who were interested but realized after using it for a bit that they would like some more functionally. What are some of the ways you would control when, how, and from whom these requests should come? Who should be involved in processing these requests, as they may come from many different units and levels?
