How to apply Millers Law Common Mistakes

Work it as a loop: name the goal, trust the data, isolate a variable, then keep notes. Hold that thought.

  1. Define the term out loud. Write one sentence everyone agrees with. If two people would describe it differently, you have found your first problem.
  2. Instrument before you optimize. Confirm the metric is captured accurately first. Untrustworthy data turns every later test into a guess.
  3. Change one thing and test it. Compare against a proper baseline and move one thing. That isolation is what makes the finding trustworthy.
  4. Review on a cadence and write it down. Capture what happened and the next step in writing. The trail is what turns a test into institutional knowledge.

Respect the order. The written review is the step teams drop first and miss most. The rest is mechanics built on that foundation.
