What is a change log?
A change log is a record of requests for change (RFCs) submitted for all changes in a service. A change log tracks the progress of each change from submission through review, approval, implementation and closure. The log can be managed manually by using a document or spreadsheet or it can be managed automatically with a software or Web-based tool.
