"Tom said like 10 sentences in a row, kind of like a geometric proof, that just so blew my mind I almost drove off the road. I realized I had wasted hundreds of hours in boardrooms arguing about errors of which we were aware of perhaps 10%."
Simon shares the moment Tom's framework clicked for him. The insight? Traditional testing—finding bugs and defects—is the wrong focus entirely. It's a programmer's view of the world. Managers don't care about bugs; they care about results, about improvements in their business. Tom calls this shift moving from "testing" to "measurement of enhanced or increased value at every cycle."
The American Toast Problem"How do we make toast in America? We burn the toast, and then we pay someone to scrape off the black bits off the bread."
Vasco invokes Deming's classic analogy to describe traditional software testing. The entire testing-at-the-end approach is fundamentally wasteful. Instead, Tom advocates for continuous measurement against quantified values. If you expected 3% progress toward your goals this week and didn't get it, you've learned something critical: your strategy needs to change. If you did get it, keep going with confidence.
Four Questions at Every Checkpoint"Where are we going? Where are we now? Where should we have been at this point? And why is there a gap?"
Drawing from fighter pilot doctrine, these four questions should be asked at every micro-cycle—not just at quarterly reviews. Fighter pilots ask these questions every minute during critical missions, with clear abort criteria if answers are unacceptable. Most organizations have no abort criteria for their strategies at all, guaranteeing they'll discover failures far too late.
