Why Expensive Software Development Never Looks Expensive

Every organisation that has run a significant software system for more than a few years has felt a version of the same thing: a change that should have taken days takes months, nobody can quite explain why, and the explanation that eventually gets offered — the domain is complex, the requirements changed, the previous team was careless — is almost never checked against an alternative approach for the software architecture or alternative framework choices, because the alternative was never built. There is no possible comparison to determine the solution chosen is a good one and there is no benchmark to measure "fit for purpose." This is the unfalsifiability problem, and it is worth stating plainly before anything else in this piece, because it is the reason the cost described below is so rarely traced back to its actual cause. Every system is built once. There is no version of your platform built the other way, running alongside it, that anyone can compare it to. So when a system works, the approach that produced it gets read as validated. When a system becomes expensive to change, the cost gets attributed to anything except the structural decision that caused it — because that decision was made years ago, by people who may have moved on, and there is no control group to prove that the structure was the variable that mattered. That absence of a control group is not a minor academic point. It is the reason a specific, avoidable pattern of cost has been able to spread through the industry for decades, get taught in courses, get validated in interviews, and still never be clearly named as a mistake. This article is an attempt to name it — and to offer something more useful than a diagnosis: a way to check, this week, whether it applies to you. The Villain: Process Over Product Ask almost any team building a significant piece of software what the goal of the project is, and the honest answer, more often than anyone would like to admit, is not "build the best-fitting prod
