All of the following stakeholders participate in the prioritization of requirements except for which one?

The project manager participates in prioritization to balance requirements against project constraints such as schedule, budget, and scope.

Implementation SMEs contribute by evaluating technical complexity and implementation effort, which directly informs how requirements should be ranked.

Domain SMEs provide business context and relative business value assessments that are essential to evaluating and ranking requirements accurately.

Requirements prioritization requires input from stakeholders who can assess business value, technical feasibility, and project constraints - roles specifically filled by the project manager, domain SMEs, and implementation SMEs. The project team as a collective executes work based on already-prioritized requirements but does not hold the authority or specialized perspective needed to make prioritization decisions. Prioritization responsibility rests with those accountable for project outcomes and those with domain or technical expertise.
