Residual complexity

Definition

The friction, ambiguity, and repair labor that remains unresolved after a formal model simplifies a workflow. A formal system does not eliminate what it cannot represent; it redistributes the burden of dealing with it. What is left out of the formal representation becomes residual complexity.

The political question is who has to carry this residual, and with what power to challenge or correct the system. Where a system has no repair channel, users bend around rigid software, workers patch edge cases by hand, and citizens spend their own time on bureaucratic procedure.

BurdenStructural

Tests that show it is in place

  • The volume and duration of manual interventions needed to make automated outputs usable are tracked.
  • The residual effort of resolving model failures is compensated, and a route to challenge exists that can change the outcome.
