What problem does it solve? Requirements change constantly during a project, and without formal traceability and change control, teams lose track of why requirements exist, what they affect, and whether they were implemented. This Skill governs the full requirements lifecycle following the BABOK v3 Requirements Life Cycle Management knowledge area. ## Core Features & Use Cases - Traceability Matrix (RTM): Builds and maintains backward traceability (requirement to business need) and forward traceability (requirement to component and test case) with 10 lifecycle states. - Change Request Management: Documents CRs with impact analysis across scope, schedule, cost, quality, and tests, routed through governance decisions (approve, reject, defer). - Baseline Control: Creates versioned baselines (initial, sprint, release) that cannot be modified without a formal CR, preventing uncontrolled scope creep. - Use Case: A sponsor requests a mid-project change to an approved requirement. Use this Skill to document the CR, assess impact on related requirements and test cases, route it to the CCB, and update the RTM and baseline version accordingly. ## Quick Start Use the ba-requirements-lifecycle skill to build a traceability matrix for my documented requirements and set up the change request process for the project.
