Plain definition
An authorisation matrix translates the organisation’s delegation into an operational map. For each transaction or decision type, it identifies the authorised role, limit or condition, required evidence, and escalation route. It gives staff and systems a common answer to “who may approve this, on what basis, and what happens if it falls outside the rule?”
The matrix is not the delegation itself; it must agree with the approved authority policy and stay current when roles, systems, or legal entities change. A clear table still fails if its workflow routes requests to departed people or lets an informal email replace required evidence.
Illustrative example
Suppose an employee requests a new supplier for a service contract. The matrix routes the business need to procurement, supplier tax and bank details to finance validation, and the contract to the appropriate approver based on its full commitment. Because the contract exceeds the manager’s limit, the workflow adds the next authorised level and keeps the supporting documents with the request.
The employee does not have to guess whom to ask, and the approver sees the evidence relevant to that decision. If the normal approver is absent, the matrix directs the request to a named alternate or escalation route instead of inviting an undocumented verbal approval.
An effective matrix identifies roles rather than relying only on individual names, while the system must reflect current people in those roles.
Why it matters
It turns broad governance policy into repeatable decisions that staff can follow during routine work and urgent requests.
It exposes gaps where a system route, approval rule, or document requirement no longer matches the organisation’s actual structure.
Practical consequence
Walk a sample of new suppliers, contracts, and payments through the matrix and the live workflow, comparing roles, evidence, limits, and escalation.
Control version changes, update access when people move roles, and investigate requests that leave the process without the documents the matrix requires.
