CAD.4:3 - Forces
| Force | Consequential tension |
|---|---|
| Fidelity, horizon and execution time | More planning information can arrive too late to be useful. |
| Strong correction and implementation limits | A gain that shrinks error can increase input, noise sensitivity or computation. |
| Feasibility and performance | Staying within limits does not establish progress, optimality or adequate tracking. |
| Design model and running system | A proven nominal schedule may differ from actual latency, sharing and failure behavior. |
