What-changed / why / so-what / now-what analysis discipline
Problem solved: Analysts ship charts without conclusions; a 4-question discipline forces every analysis to end with a confidence-stated recommendation.
What
A data-analysis discipline requires every metric review to answer four questions in order — what changed, why it changed, so-what (business impact), now-what (recommended action) — and to state a confidence level on the conclusion. Turns "here's a chart" into a decision the reader can act on.
