Here is the short version. 1. **Define the term out loud.** Pin it to a single sentence in plain words. If colleagues define it differently, fix that before anything else. 2. **Instrument before you optimize.** Check the tracking is honest and complete. An unreliable number makes optimization a coin flip. 3. **Change one thing and test it.** Run a controlled comparison rather than a vibe. Isolate the variable so the result is causal, not a coincidence of seasonality or mix. 4. **Review on a cadence and write it down.** Write down the change, the effect, and the next idea.
