Drop-off behavior ☛Pick-up behavior ☛Two distinct lanes are for, respectively, drop-off and pick-up.
After a waiting period in the drop-off lane, visitors reach a numbered desk. They lay down all their belongings on the desktop for a photography. Staff may optionally remind people that bags are totally unauthorized in the MOMA to effectively get all visitors' belongings. The photography is recorded along with a requested phone number. Staff stores belongings while a MMS is sent with the taken photography as “deposit proof”. A light panel (assigned to each numbered desk) then turns leave/green when the MMS succeeds (checked through the desktop's computer). In case of “erroneous” phone number, light panel keeps displaying wait/red. To that event, visitors are invited to re-propose something valid until success.
Pick-up leads visitors to reach any numbered desk from the pick-up lane after a waiting period. Visitors provide their phone number. People get their belongings and leave the place when leave/green turns on. This results from staff enactment on their desktop's computer.
Note that a numbered desk's light panel turns wait/red as soon as a sensor detects presence in front of the desk.

SysML Requirement Diagram offers dedicated requirement-based relationships like
«allocate»,«refine»,«satisfy»… to focus on traceability: how requirements relate to each other and, later on, to derived elements (use cases…) within models through solution(s).
