The inclusion of new information into the product's functional requirements as more details become known is called

• A. Decomposition
• B. Scope Creep
• C. Kanban
• D. Progressive Elaboration

Answer: (D)

Progressive elaboration is refining the product's requirements as more details become known. It starts with broad, high-level requirements and, as stakeholders provide more information and constraints become clearer, adds specifics and clarifies acceptance criteria. This process exactly describes updating functional requirements when new information surfaces, so the requirements become more precise over time.

Decomposition focuses on breaking work into smaller components, not on updating requirements. Scope creep refers to uncontrolled expansion of project scope, which is more about scope growth than the deliberate refinement of requirements. Kanban is a workflow management method, not a concept about expanding or detailing requirements.
