Requirements that are good candidates for reuse are those that are not tied to a specific tool, technology, or system. These requirements are generally applicable across various contexts and can be used in multiple projects without significant changes. They are typically high-level business requirements that describe what the business needs without prescribing how to achieve it. This makes them flexible and adaptable to different situations, which is essential for reuse.

References: The concept of reusable requirements is discussed in the context of Business Analysis, where it is emphasized that requirements should be general enough to apply to multiple situations while still being specific enough to provide value. They should also be stable, meaning they are unlikely to change over time1.

Traceability is a tool used in business analysis to track the life of a requirement from its origin through its development and specification, to its subsequent deployment and use, and through periods of ongoing refinement and iteration in any of these phases. It allows business analysts to determine the impact of changes in requirements by providing a clear path of how each requirement is connected to others, which is essential for assessing the consequences of changes.

References: The BABOK® Guide emphasizes the importance of traceability in managing and analyzing the impact of changes in requirements. It is a fundamental aspect of requirements management and communication, one of the six knowledge areas defined in the BABOK® Guide. Traceability supports several tasks within this knowledge area, including maintaining requirements for reuse, preparing requirements for change, and evaluating the potential impact of changes1.

During the requirements life cycle management phase, one of the key activities is to trace requirements. This involves ensuring that requirements and designs at different levels are aligned with one another and managing the effects of changes to one level on related requirements and designs. Tracing requirements helps maintain the integrity of the requirements throughout the project’s life cycle, from inception to retirement.

References: The information provided aligns with the tasks described in the BABOK® Guide’s Requirements Life Cycle Management knowledge area, which outlines the importance of tracing requirements to manage and maintain them effectively throughout the project12.

Among the activities performed during the requirements life cycle management phase, tracing requirements stands out as a critical task. It involves tracking and documenting the lineage of each requirement, including its derivation, allocation to solution components, and relationships with other requirements. This process ensures a clear understanding of how requirements influence and are influenced by each other, as well as their relationship to the business objectives and solution components. Effective requirement tracing aids in impact analysis, risk management, and ensuring that changes to requirements are consistently reflected across the project, thus maintaining the integrity and coherence of the solution over time.
