OPS.8.1:3 - Forces
| Force | Practical tension |
| Earlier release and correction capacity | Starting sooner can advance new work but occupy the resource needed when an earlier result returns. |
| Simple counts and unequal demands | One freed place is easy to recognize; the returning and incoming jobs may require very different resources and times. |
| Protection and useful idle time | Holding capacity can preserve a deadline; excessive protection postpones work without improving the required service. |
| Feedback timing and decisions | Waiting can reveal whether a return is needed, but that information may arrive too late to protect the result. |
| Local pace and the receiving result | A constraint’s completion can regulate replenishment while another resource or downstream join determines customer delivery. |
