The Platform Management Plan shall include the Project Management Plan, Configuration Management Plan, Change Management Plan, Documentation Management Plan and Problem Resolution Plan. Plan to ensure that all work products can be uniquely identified and reproduced in a controlled manner at any time. Plan to ensure that relations and differences between versions can be traced. Plan to manage, analyse and control changes of the work products during the project life cycle. Documents should be precise, concise, clearly structured, understandable for intended users, verifiable, maintainable, and organized according to in-house procedures to facilitate information retrieval. Documentation guideline requirements must be defined for each WP. Each work product or document must include a title, author and approver, unique revision identification, change history, and status. |
