| Assignment | Named door retained until reassigned. | User selects or is given any suitable free door. | Rules engine assigns or recommends a suitable door. |
| Typical duration | Weeks, months or ongoing. | A visit, shift or defined booking. | Transaction, booking or policy-defined period. |
| User certainty | Highest continuity. | Capacity is available, but not necessarily the same door. | Depends on rules, live availability and service design. |
| Space utilisation | Usually lowest when attendance varies. | Higher because released doors are shared. | Potentially highest when rules balance demand effectively. |
| Administration | Joiners, movers, leavers and audits require active control. | Policies must prevent long-term occupation and abandoned sessions. | Rule ownership, data quality and exception monitoring are essential. |
| Technology dependency | Lower for simple named assignments. | Needs session access, availability and automatic release controls. | Highest: identity, workflow data and reliable decision logic. |
| Main risk | Empty reserved doors and hidden underuse. | No suitable free door at a peak or users failing to release. | Poor rules or data producing unsuitable assignments. |
