Alternating installation labour
Interpretive workflow diagram, 1990s
Observed surface
MACHINE: copy → expand → verify → REQUEST
PERSON: notice → locate → eject → insert → confirm
MACHINE: verify label → copy → expand → REQUEST
Implied procedure
Neither participant performs the complete installation.
The request state is a handoff whose duration belongs to the person while its consequence belongs to the process.
Interpretive residue
A progress bar measures machine work more readily than availability, attention, or distance to the disk stack.
The diagram restores those unmeasured actions to the installation timeline.
