Requisition

The formal, approved statement of need that authorises procurement to go and buy something.

Why it matters operationally

Procurement language distinguishes a request (someone wants this) from a requisition (the organization has agreed to it). The distinction matters at audit: the requisition is the document that says a person with authority signed off, and it is what a purchase order is raised against.

How Roadmap handles it

Approval is that boundary. What procurement reads is built only from approved requests, so nothing reaches a buyer that a planner has not agreed to.
