If you got confused with project scope, remember that the above statements describe the features, functions, and requirements which are part of defining product scope. To differentiate project scope from product scope read through the definition of each. Product scope: the features and functions that characterize a product, service, or result. Project scope: the work that needs to be accomplished to deliver a product, service, or result with the specified features and functions. The product scope describes the function or service that will exist as a result of your project. The project scope, on the other hand, describes all the work to create the product scope. It includes only the required work to complete the project deliverable. Note: The completion of project scope is measured against the project management plan, the project scope statement and its associated Work Breakdown Structure (WBS), WBS dictionary, and scope baseline. Completion of product scope is measured against product features or requirements.
