| Intent | The interface should expose, and the system should enforce, distinctions between objects and between actions along boundaries that matter to the user. |
| Motivation | If the distinctions are too detailed, there is an increased risk that users will overlap or leave out specifications. On the other hand, if the boundaries are too few, users will be forced to give away more authority than they intend. The right distinctions can be discovered by asking oneself if there are situations where the user would ever want to manipulate one authority independently of another, to grant an authority to one actor but not another, to permit access to one resource but not another, and so on. |
