Engines decide. Operating Systems run the function.
| Decision Engine | Operating System | Application |
|---|---|---|
| Owns one recurring decision under uncertainty. | Runs a whole function by composing the engines it needs. | Owns the durable records and workflow of the business. |
| Learned models forecast the outcome and price each permitted action. | Carries the job from its first signal to a measured outcome, with handoffs between engines. | Users, transactions, approvals and controls in one system of record. |
| Measured against a financial or operational decision baseline. | Measured on the function's end-to-end result. | 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.
