Which requirement property must be prioritized for all project participants?

The prioritization of practicability of requirements is essential for all project participants because it directly influences whether the requirements can realistically be achieved within the constraints of the project. Practicability ensures that the requirements can be implemented given the available resources, technology, time, and budget. When all stakeholders have a clear understanding of which requirements are practical to pursue, it leads to more effective planning, resource allocation, and execution of the project.

Prioritizing practicability also fosters collaboration among team members, as everyone can align their efforts towards achievable goals, minimizing the risk of project failures caused by attempting to pursue unrealistic or overly ambitious requirements. This focus on practicability helps teams manage expectations and deliver results that meet the stakeholders' needs efficiently.

While qualities like consistency and changeability are important, they do not have the same immediate impact as practicability in ensuring that all participants can work towards what is feasible. Evaluated requirements, while useful, are often more of a review process rather than a guiding principle for prioritization across a project team.
