How Operating Systems use Decision Engines.
| Decision Engine | Operating System | Application |
|---|---|---|
| Handles one recurring decision with an uncertain outcome. | Runs a complete business function by combining the engines it needs. | Holds the business records and runs the workflow around them. |
| Machine learning forecasts the outcome and prices each permitted action. | Runs the work from the first signal to a measured outcome, with handoffs between engines. | Users, transactions, approvals and controls in one system of record. |
| Measured against an agreed financial or operational baseline. | Measured on the result for the whole function. | Measured through adoption, reliability and the work it supports. |
Each engine keeps its own models, authority and measurement inside an Operating System. An engine can serve more than one system without being duplicated.
