In requirements prioritization, which criterion is considered unsuitable?

In the context of requirements prioritization, assessing the "Effort required for validation" is generally considered unsuitable as a standalone criterion. This is because prioritization should focus on how the requirements will benefit the project or contribute to the overall success of the system, rather than the complexity or effort involved in validating those requirements.

Prioritization typically considers factors that reflect the value and impact of each requirement on the project outcome. Criteria like the impact on the operational system, the influence on overall success, and the costs of implementation are all integral to understanding how critical a requirement is to meeting business objectives and ensuring system effectiveness. These aspects directly correlate with the value that a requirement brings to stakeholders and the organization.

On the other hand, the effort required for validation is more about the internal processes of ensuring that a requirement is correctly implemented and does not necessarily reflect the strategic value or priority level of that requirement. As a result, this criterion does not align with the primary objectives of prioritization, which emphasize the value and impact of requirements rather than the associated workload for validation tasks.
