Every System Has a Maintenance Bill

Launching something creates a new responsibility. A website needs updates. A road needs repairs. A data pipeline needs someone to notice when its inputs change. The first version is the beginning of an operating commitment.

Yet proposals often describe the cost of construction more clearly than the cost of continued use. The result can be an impressive asset with no realistic plan for maintaining it.

A better review asks four questions. What can deteriorate? How will we detect it? Who is responsible for responding? What resources will they have?

These questions apply beyond software. Any project that changes a shared environment should consider the people who will live with its consequences. A benefit enjoyed by one group can create a recurring burden for another. Making that burden visible is part of evaluating the design.

It is also worth considering whether a decision can be reversed. A small reversible experiment offers a different kind of risk from an intervention that is expensive or impossible to undo. The level of evidence should reflect that difference.

Maintenance is sometimes treated as less creative than building. In practice, it requires close observation, judgment, and a willingness to respond to conditions that were not anticipated.

Before approving the next addition, describe its future operating life in ordinary language. If the explanation depends on someone eventually figuring things out, the proposal is not finished. A durable project includes a credible plan for what happens after the celebration.
