Definition
The baseline flow of upkeep—patching, cleaning, rehearsing, and caring—that keeps a service alive when nothing is on fire. Healthy maintenance metabolism is budgeted, scheduled, and shared rather than squeezed between crises.
Falling below it signals rising maintenance debt and invites maintenance windows before fragility compounds.
Scope
F. Burden & load. How systems allocate the cost of operation or failure.
Operational tests
- Evidence appears in documentation, interface cues, or governance artifacts that reflect maintenance metabolism.
- Teams can point to a concrete example that demonstrates maintenance metabolism in practice.
Genealogy
Ethotechnics uses Maintenance Metabolism to extend the f. burden & load vocabulary and connect governance, design, and policy teams.
