A change log is a document that contains the list of changes that are made during the project. It tracks the progress of each change based on its review, approval, implementation, and closure. A change log is a useful tool for communicating the status of change requests to the stakeholders, as it shows the impact and outcome of each change. A risk log, a backlog, and an issue log are different documents that serve different purposes. A risk log records the identified risks, their probability, impact, and response strategies. A backlog is a list of features or tasks that need to be completed in an agile project. An issue log records the issues that arise during the project, their causes, effects, and resolution. References:
