leadership troubleshooting

Ellis has built his entire book around a single, sturdy metaphor — the boiler technician's discipline of not "parts changing" — and then does the hard work of actually earning that metaphor across every chapter rather than just naming it once and moving on. The shrub-blocking-the-vent story in Chapter 3 is the clearest proof of the method working: a mechanical mystery that costs a homeowner a fortune in unnecessary parts turns out to be landscaping, and Ellis draws the parallel to his own police training washout with real restraint, refusing to let the story resolve into either "I was blameless" or "I was the problem." That refusal is the book's real strength. He doesn't let himself off the hook (the Osborne's Plumbing diner scene is a genuinely uncomfortable confession — he admits he never got the meeting, never heard their side, and still isn't rewriting dialogue for them decades later just to make the story land better), and he doesn't let his old organizations off the hook either.

The four-boiler night-lockout story in Chapter 4, where the sensor itself was blind rather than the ignition system faulty, is the sharpest single illustration in the excerpt of how symptom and cause diverge — and Ellis trusts the reader enough to sit with the mechanical detail before pivoting to Camdon the camper-turned-fishing-instructor, which is the most human and specific case study here. The takeaway is concrete and usable: before diagnosing a person, ask what changed in the system around them.

This earns a Booky for Theme & Substance because the argument isn't decoration — it's method, applied consistently, with the humility to admit when the diagnosis stayed uncertain.
