Disk maintenance sign-up sheet
Reconstructed shared-PC practice, c. 1998
Observed surface
MON 18:00 accounts workstation / requested by operations
TUE 12:30 design workstation / deferred: machine in use
FRI 17:30 reception workstation / approved after close
Implied procedure
Expected duration is written as 20–120 minutes, a range broad enough to be operationally awkward.
The task needs exclusive access, stable power, and permission to occupy a machine that otherwise appears available.
Interpretive residue
Maintenance waits for a gap in human demand before humans can wait for maintenance.
The sign-up sheet is a queue whose purpose is to create another uninterrupted queue of block movements.
