Current: My most recent field note — The Waste Stream Doesn't Lie — reads this week's data-center waste headlines through a Define-phase lens: the dumpster is a process output nobody gave an owner. Read the note →
Field notes
Green Belt lens: DMAIC is a diagnostic, not a ritual. Define → Measure → Analyze → Improve → Control. Each step answers one question; skip one and the "improvement" is a guess.
The 7 wastes (muda): transport, inventory, motion, waiting, overproduction, overprocessing, defects.
Numbers that move me: ~3.4 defects per million at 6σ (1.5σ shift assumed) vs ~67k at 3σ. That gap is the price of sloppy Define.
Rule I live by: you cannot fix what you cannot first measure to a baseline.
