What problem does it solve? Requirements change constantly during a project, and without formal traceability and change control, teams lose track of what was approved, what changed, and why. This Skill governs the full requirements lifecycle so every requirement stays traceable from business need to implementation and test. ## Core Features & Use Cases - Traceability Matrix (RTM): Builds and maintains a matrix linking each requirement to its origin, component, test case, and lifecycle state across 10 defined states. - Change Request Management: Documents CRs with impact analysis covering scope, schedule, cost, quality, and tests, plus governance decisions (approve, reject, defer). - Baseline Control: Creates versioned baselines (initial, sprint, release) so scope creep is measurable and modifications require formal CRs. - Use Case: A stakeholder requests changing an approved business rule mid-project. Use this Skill to document the CR, assess impact on related requirements and tests, route it through governance, and update the RTM and baseline accordingly. ## Quick Start Ask the assistant to run the ba-requirements-lifecycle step to build a traceability matrix and process pending change requests for the current work package.
