SYSE.26:3 - Forces
| Force | Practical tension |
|---|
| Simple entry | Hiding irrelevant implementation detail helps; hiding a condition that changes the result makes use unsafe. |
| Supported variation | A common route reduces repeated effort, but one rigid template can exclude legitimate work. |
| Retry and recovery | Users need a next move after uncertainty; repetition can duplicate an already completed effect. |
| Low coordination | Self-service can reduce case-specific assistance, while maintenance and exception support still need capable providers. |
