Start with the problem, not the software
Youth football has professionalised its thinking much faster than its tooling. Clubs that would once have had no written philosophy now have serious playing models: how they want to build, how they want to press, what a player at each age is expected to be able to do. Technical leadership is a real job in far more clubs than it was ten years ago.
What has not changed is the gap between that thinking and the pitch. A playing model is written by one or two people. It is delivered by dozens of coaches, most of them part-time, across age groups with different needs, over a season long enough that everyone forgets what was agreed in August.
The result is a club that can describe how it plays and cannot demonstrate it. Nobody is at fault. There is simply no mechanism connecting the intent to the delivery, or the delivery to any record of what happened.
