Test the riskiest assumption before you build the whole thing.
Turn your idea into falsifiable hypotheses and run the smallest experiment that could prove you wrong. Most sports technology projects fail not because the team built badly — but because they built the wrong thing. Lean is the discipline of finding that out in weeks, not after a six-figure build.
The key move is identifying the riskiest assumption — the thing that has to be true for your idea to succeed — and designing the smallest experiment that would tell you whether it's true or false. Not a prototype, not a pilot: a signal. In sport, where budgets are tight and supporter trust is hard to rebuild, getting this signal cheaply is not optional.
We believe [specific group of fans or members]
will [specific behaviour we expect]
because [the reason we believe this is true].
We'll know this is true when [metric] reaches [target]
by running [minimum viable experiment] in [timeframe].
If we're wrong, we'll [what we'll do instead — pivot, stop, or reframe].
The riskiest assumption is usually the one nobody wants to talk about. That's exactly the one to test first.
A Data Vanguards diagnostic helps you design the experiment, interpret the signal, and decide what to build if the hypothesis holds.
