Which definition best characterizes the term "traceability" in terms of requirements engineering?

The term "traceability" in requirements engineering refers to the ability to follow the progression of requirements throughout the entire development lifecycle, from the initial elicitation phase through to implementation. This encompasses not just the requirements themselves but also any associated documentation, ensuring that there is a clear line of sight from what was originally proposed to what is ultimately built.

This concept is crucial in managing changes, verifying implementation, and ensuring that the final product aligns with both stakeholder expectations and original requirements. It facilitates validation and verification processes by enabling stakeholders to track how requirements are satisfied at various stages of the development process. Additionally, traceability supports impact analysis, making it easier to understand how changes in one requirement may affect others or the overall project.

The other options, while related to aspects of requirements engineering, do not capture the full essence of traceability. They focus on monitoring progress, analyzing contradictions, or assessing stabilization between requirements, rather than the comprehensive journey and connections of requirements throughout the project lifecycle.
