Explanation
A work product is a term given to the collection of notes and diagrams used by the business analyst to develop the requirements during the requirements development process. A work product is any artifact created or modified as part of the business analysis work, such as models, diagrams, matrices, documents, or presentations12. A work product can be used to communicate, analyze, verify, or validate the requirements, or to support decision making or problem solving3. A deliverable is a work product that is formally reviewed, agreed upon, and delivered to a stakeholder or customer4. A supporting requirements package detail is a component of a requirements package that provides additional information or clarification for the requirements, such as assumptions, constraints, issues, risks, or glossary. A work package is a set of related tasks or activities that produce a specific output or deliverable within a defined time and cost. References:
