Planned maintenance

Planned maintenance is the work you do before something fails: the half of property maintenance that requires structure and a calendar to surface, as opposed to the half that announces itself. It is the standard of professional property management, where corrective work is the residual category rather than the entirety. Most residential homeowners run almost entirely without it, not for lack of care, but because nobody has handed them the document the planned half is built on.

The mechanism: planned maintenance has two practices, and both are needed for either to deliver. Preventive maintenance is the periodic inspection and servicing that catches problems early, before they cause failure. Lifecycle maintenance is the longer-horizon view that pushes each component toward its full lifespan and anticipates the eventual replacement. Lifecycle without preventive produces shortened lifespans, because the routine work that protects the component is missing. Preventive without lifecycle produces servicing on components that are about to be replaced anyway, and skipped servicing on components that should still have a decade of life. The two practices feed each other.

The distinction matters at three moments. Setting up a household maintenance plan (the document is what defines planned work). Reading a contractor quote on a recurring service contract (the work is preventive, the schedule is lifecycle). Deciding whether to defer a maintenance task in a tight financial year (the plan tells you which deferrals are calculated risks and which are silent neglect).

Sibling frame: planned is the opposite of corrective maintenance (the reactive work that happens after a failure). The shift from corrective-default to planned-default is mechanical, not motivational, because the difference is whether the document exists, not whether the homeowner is trying harder.
