4P rule

The 4P rule asks whether a defect endangers any of four categories: People (safety or health hazards), Pets and environment (toxic exposure or contamination), Production (whether the space still functions for cooking, sleeping, working, showering), and Possessions (damage to belongings or the building itself). If any answer is yes the defect is urgent; if all four are no it can wait.

The mechanism: urgency in the 4P sense is a permission, not a panic instruction. Non-urgent does not mean “ignore.” It means the time you just bought is the resource that lets you check warranties, compare quotes, wait for the right season, or bundle the repair into another scheduled visit. Each of those actions makes the eventual repair cheaper or more durable.

Worked example. Saskia in Utrecht finds a brown stain on the kitchen ceiling, directly below the bathroom, larger than it was yesterday. People: nobody’s health or safety is at risk today. Pets and environment: no. Production: bathroom and kitchen both still work. Possessions: yes. Water is damaging the ceiling and whatever it runs through, and it is spreading, so every day of active leak adds consequential damage to the eventual bill. One yes makes it urgent: water off, plumber today. The same month, a seal fails in her bedroom window and the double glazing fogs. All four answers are no; the window goes on the list with a date, bundled into the autumn maintenance visit.

The distinction matters at three moments. When something breaks at midnight and you are deciding whether to call now. When a contractor pressures you with “this is urgent.” When you are tempted to defer indefinitely without a date attached.

Sibling frame: stopgap, the temporary measure that buys time when the 4P answer is mixed. The opposite failure mode is silent neglect: a non-urgent defect with no date attached silently becomes “never did,” and the consequential damage starts to accumulate.
