Which technique is commonly used for requirements validation?

Prototyping is an effective technique for requirements validation because it allows stakeholders to visualize and interact with a preliminary version of the solution. This hands-on approach facilitates feedback and helps identify any gaps or misunderstandings in the requirements early in the project lifecycle. By creating prototypes—whether they are low-fidelity sketches, wireframes, or high-fidelity interactive models—stakeholders can better understand the functionality and features being proposed. This not only clarifies expectations but also allows for adjustments before the development phase begins, ultimately leading to a more successful end product that meets user needs.

Other methods, such as cost-benefit analysis or SWOT analysis, focus more on evaluating the feasibility or context of a project rather than directly validating the requirements themselves. Stakeholder interviews, while valuable for gathering initial requirements, do not provide the same interactive means to confirm those requirements as prototyping does. Through prototyping, the iterative feedback loop from stakeholders directly informs and refines the requirements, which is crucial for ensuring their accuracy and completeness.
