The moment you harvest a platform out of an app, the app stops being something you can change quietly. That standing cost lands hardest on the team that built it, and most extraction plans never budget for it.
I argued the way to find a platform’s real boundary was to watch the second team that wanted in. The catch I keep running into: two consumers tell you what they have in common, and that’s not the same thing as what the platform is.
You built an app. It worked. Then a second team showed up and couldn’t use it without inheriting every opinion you baked in. Congratulations, there’s a platform hiding inside your application.
