Analyse the current situation. 2. Redefine and document the roles a. Define, in close consultation with the project manager, what roles are needed and what they mean for the working of OceanExpert. b. The new roles will have clear names that describe the attached roles in OceanExpert. c. Provide a clear documentation on those roles. d. Provide a manual on how the roles are used in OceanExpert. 3. Provide PHPUnit tests to test the roles in OceanExpert. These tests will be committed to a specific GIT branch, dedicated to this development. 4. Apply the necessary code changes to a specific GIT branch. The changes will reflect the new roles on all pages and actions in OceanExpert (web interface, API, …). Frequent commits, with readable comments, will be made to the specific GIT branch. No changes will be made to the database structure.  5. Implement a logging system to keep track of the actions of users with their specific role.
