Scope Management Process

Collect Requirements:

You find /collect all of the stakeholder’s needs and  then write down so you know what to build and your requirements can be  tracked and measured.

Product scope VS Project scope

Product scope is "requirements that relate to the product of the project" It answers the question of "What end result is wanted?" Product scope may be supplied as a result of a previous project to determine requirements, or it may be created as part of the project. Example a project to build a new dam, the product scope might be "deliver a new dam that meets these technical specifications" To determine if the product scope has been completed on a project, the resulting product (the dam) is compared to the product requirements, which are recorded in the requirements documentation and the project scope statement for the project.
