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
Constraints
Identifying constraints that are applicable to the project ensures that the deliverables are feasible. No software application can be constructed or implemented without an understanding of the technical environment where it will reside. No business application can be constructed or implemented without an understanding of the legal environment where it will reside. The solution must support the technical IT policies and security standards, and the law and regulations applicable to the business and/or business process. Constraints affecting the solution are important to identify non-functional requirements and to use when communicating with project stakeholders during the development of the functional requirements.
