Despite its antiquity, the context diagram remains a useful way to depict the environment in which a software system exists. The venerable context diagram dates from the structured analysis revolution of the 1970s. Related: Project Management Best Practices This is a form of expectation management, an important contributor to project success. Itemizing them as exclusions makes it clear that they won’t be. Some stakeholders involved with this project might have expected these capabilities to be included.

I know of a project to build a Web site for a national sports team that included the following exclusions for the initial release: Instead, the limitations should identify capabilities that a reader might expect to be included in the project, but which are not included. Obviously, you can’t list everything that’s out of scope because that would include every detail in the universe except for the tiny sliver that is in scope for your project. Your scope definition also should include a list of specific limitations or exclusions-what’s out. The scope statement defines the boundary of the project manager’s responsibilities. The scope definition helps the project manager assess the resources needed to implement the project and make realistic commitments. It identifies the external interfaces between the system and the rest of the world. I define the product vision as: “A long-term strategic concept of the ultimate purpose and form of a new system.” The product vision could also describe the product’s positioning among its competition and in its market or operating environment.Ī well-defined scope sets expectations among the project stakeholders. I think in terms of the product vision and the project scope. Vision and Project Scopeīoth the vision and the scope are components of the project’s business requirements. Any project of any size, though, will benefit from such strategic guidance, even if it’s just a paragraph or two at the beginning of the requirements specification.

You don’t necessarily need a standalone vision and scope document for a small project. The vision and scope document (often including a use case diagram and a context diagram), otherwise known as the MRD (marketing requirements document) or business case, is a key deliverable in defending against scope creep. They cannot be distributed or used for another purpose.Every product development team talks about project scope and team members often complain about unending scope creep.
