Requirements Management

The process of working with a defined set of product requirements throughout the product’s development process and its operational life. Includes tracking requirements status, managing changes to requirements and versions of requirements specifications, and tracing individual requirements to other project phases and work products.

Requirements Traceability Matrix

A table that illustrates logical links between individual functional requirements and other types of system artifacts, including other functional requirements, use cases, architecture and design elements, code modules, test cases, and business rules.

Retrospective

A review in which project participants reflect on the project’s activities and outcomes with the intent of identifying ways to make the next project be even more successful.

Risk
