The Scrum Master should be selected based on characteristics such as problem-solving ability, availability, commitment, facilitation capability, and a supporting/servant leadership style. SCRUMstudy specifically identifies availability for meetings, skills for removing impediments, and commitment to maintaining a conducive work environment as relevant selection criteria.

Option D violates Scrum's principle of self-organization. The Scrum Master does not make technical implementation decisions on behalf of the Scrum Team. The Scrum Team has the authority and responsibility to determine how Prioritized Product Backlog Items are converted into finished deliverables. The Scrum Master's function is to facilitate, coach, protect the process, and remove obstacles—not to act as a technical project manager.

This distinction is fundamental. If the Scrum Master dictated technical decisions, responsibility would shift away from the self-organizing, cross-functional team and recreate a command-and-control structure inconsistent with Scrum.

Therefore, technical decision-making authority on behalf of the Scrum Team is not an appropriate Scrum Master selection criterion.
