You are the business analyst for your organization. Management has asked that you create a method to store the project requirements including those under development, under review, and the requirement

A change management system is used to track and control changes to already-approved requirements, not to store requirements across multiple developmental states.

A repository is a centralized storage system that holds requirements artifacts in multiple states simultaneously - under development, under review, and approved. It acts as a single source of truth for all requirements regardless of their current status, allowing the business analyst to manage and retrieve them throughout the project lifecycle.

A project scope statement defines the boundaries and deliverables of a project, not a mechanism for storing requirements in various states.

A requirements register is a list or log of individual requirements with their attributes, but it does not function as a full repository for managing requirements across multiple lifecycle states.
