When are requirement filters used?

Requirement filters are utilized in requirements analysis because this stage involves reviewing, categorizing, and prioritizing the requirements gathered from stakeholders. Filters help in refining the requirements by assessing their relevance, clarity, and completeness, which is vital for ensuring that only the most pertinent requirements proceed through the development process.

In this context, using requirement filters allows business analysts to manage and organize the abundance of information gathered, helping to eliminate any ambiguity and to clarify the scope of what needs to be developed. This process enhances the quality of the requirements, allowing teams to focus on what truly adds value and aligns with the project's goals.

While requirement filters could conceptually be helpful in other stages, such as stakeholder meetings, development, or testing, their primary purpose aligns closely with the analysis phase. At this point, the objective is to create a solid foundation of well-defined requirements, making the analysis phase the most appropriate stage for deploying these filters.
