The document discusses defining project scope. It explains that defining scope involves developing a detailed description of the project and product based on information known during planning. This process describes project boundaries by defining which requirements will be included and excluded. Stakeholder needs are analyzed and converted to requirements. Inputs like the project charter and requirements documentation are used along with tools like expert judgment, product analysis, and workshops to create the project scope statement output. The scope statement elaborates on product characteristics and includes acceptance criteria, deliverables, exclusions, constraints, and assumptions.
