MA.6:4.2 - Give the meanings their own revision and decision rules
Construct the forecast from adequate evidence and assumptions through MA.5. Use OPS.21 when the responsible management practice needs to construct the operating aim, target or comparison; reuse a sufficient supplied basis. Obtain actual resource decisions from their holders, with OPS.13 for supported service commitments and OPS.19 when contributions compete for shared provision. State how each result is revised and who can make the relevant decision.
Separate a request from a granted resource amount and from actual usable provision. A forecast revision does not itself authorize spending.
The distinction can be made in one small table.
