A business stakeholder — also called the requester — is the person or unit where a requirement originates and who owns its technical definition and evaluation.
Role. Describes the requirement, specifies needs, scores technical merit, signs off on delivery. Supplier selection and award sit with procurement.
Where friction arises. No procurement vocabulary, no time for tender documents, judges the process by speed.
Design principle. Guided capture, predefined scoring criteria, automatic status instead of chasing.
Scaling metric. The buyer-to-stakeholder ratio determines achievable spend under management.
