01 · MeasureWe write the prediction first.
Before we make anything, we write down what we expect it to change and how we'll know. It keeps the work honest, and it makes the debrief short.
02 · VaryWe make more than one.
Several directions, not one precious idea. The first version is rarely the fittest, so nobody gets too attached to it, including the person who made it.
03 · SelectEvidence decides. Not the loudest voice.
Buyers, data and the prediction we wrote down pick the winner. Seniority doesn't. Good arguments are welcome from anyone.
04 · InheritWe write down what we learnt.
Hits and misses both go in the log, so the next project starts stronger. It's the same loop we run for clients, and for ourselves in Generation One.
