Overview of the RLC

A Requirements Life Cycle (RLC) is a framework for managing requirements from initial concept to the continued support of an implemented solution.

An Architecture-Based Analysis (ABA) RLC integrates the best practices related to
architecture and business analysis to enhance the quality of requirements. By leveraging visualization and context, it improves the elicitation, verification, validation, and documentation of requirements data. Additionally, ABA promotes requirements reuse, helping to standardize processes across the enterprise.

Below is the ABA RLC framework, outlining each phase of the lifecycle, its alignment with other standard life cycles, and the key architectural models used throughout.
