Every board commission hits the same temptation: add region, channel, SKU, shift, and customer size until the filter row looks like an airport departures board.
The rule we write on the wall
One trusted extract. Three primary filters. Everything else becomes a footnote or a second board. When a fourth filter is truly required, we schedule a separate commission rather than smuggling it into week four.
Why three
Facilitators lose the narrative when they click five times before stating a claim. Executives interrupt earlier. Three filters force a conversation about which questions deserve live answers and which belong in the appendix pack.
