Nine years old, and it still works.

This year, a major implementation partner inside one of the sector's largest platform ecosystems published an open letter to organisations still running the 2017 version of the platform it implements.

Nine years old. And the letter opened by telling those organisations what they had already told themselves: "it still works, so an upgrade can wait."

Read that again. Not a competitor talking. Not an analyst. The people paid to keep the platform running, writing to their own customers, about the upgrade nine years of budget cycles have deferred.

It is worth asking how an organisation ends up running nine-year-old infrastructure. Nobody decides to fall a decade behind. It happens one reasonable decision at a time. Upgrading is a project. There is a cost, a consultant, a testing window, a retraining plan, a risk register. Staying still is free. And when moving forward is a project and standing still is free, standing still wins every budget round, every year, until a partner writes you an open letter.

Here is the thing that letter accidentally admits. On a platform that serves the organisation, an upgrade is not a decision. It arrives, it is absorbed, and nobody convenes a steering committee about it. Your phone did it last night. Your accounting software did it without asking. The moment an upgrade becomes a decision, a board paper, a budget line, a project with its own risk register, the platform has stopped serving the organisation. The organisation is serving it.

That is the honest test hiding inside one sentence of ecosystem marketing. Not does your platform work. Everyone running a nine-year-old platform will tell you it works. The question is what it costs you to keep it current, and who has to write to whom when you do not.

The longer argument runs through The Platform Realist. Start with the first essay, Your Platform Works. That's the Problem. It is about the difference between a platform that works and one that holds.
