PPM helps you manage the following 3 most important aspects of your project scope:
PPM helps you manage your project requirements, activities, deliverables, budgets, and deadlines. While it is possible that things can change, having the project scope defined in the beginning can definitely make it easier for you to manage and run the project, including dealing with the changes. PPM allows you to do the following:
PPM allows you to baseline the entire scope (entire WBS) of your project. By setting it in stone, you and your client can get a full view of the project from beginning to end. One of the best results of establishing a good baseline is that everyone related to the project will have the same expectations from the project and the project team. The baseline helps to communicate those expectations. By communicating the baseline and getting approval of the baseline, you can set the expectations of the client and the stakeholders involved with the project.
One of the most important aspects of requirement management is traceability. Tracing allows you to understand why the requirement exists, the impact of change, whether the set of requirements is complete, and helps prioritize requirements.
The above diagram shows how traceability in PPM starts with the business requirements’ outcomes/benefits and traces through the stakeholder requirements, solution requirements, supplementary requirements/nonfunctional, and down into testing scenarios and test cases. It is critically important to understand how they relate back up to the top.
