Documenting and Managing Requirements
This is a detailed how-to guide to ensuring your requirements are fully captured. It is a useful guidebook with processes you will tweak and adapt to each project plan. Is anything surprising or new to you? You will not use all of these approaches for every project, but having them at hand is useful when planning your next project.
Requirements Development
Existing Applications
When a project goal is to replace or enhance an existing application, that application can provide many of the requirements that will be applicable to the solution. This 'As-Is' scenario is a gold mine for determining necessary functionality and project requirements. If requirements were managed for the old application, they can be re-used, with the appropriate suitable modifications, for the current project. Maybe the project deliverable addresses a brand new need that no existing application supports. If this is the case, the project solution may need to incorporate business rules and functional requirements for multiple existing applications and business processes. This type of 'As-Is' scenario analysis is typically applicable to system integration projects.
