In the Training stage, the Release Engineer with a team educates end-users and the company at large to use the deployed service effectively. Depending on the significance of the changes deployed, you may have to provide robust ongoing training to bring your users up to speed. User training is especially important for internal releases in your organization. Employees must be aware of the changes made to any service in use and the availability of new services to ensure better productivity.
Also, the operational issues found during the initial period after the release deployment will be documented to be resolved in the next iteration.
After training, the release enters the Review stage.
