Raise Your Confidence by Strategically Stacking Evidence

Late-stage design just hit a snag—now comes the moment that separates guesswork from great engineering. We walk through a clear, repeatable method to investigate unexpected failures and make high-impact decisions with confidence. Instead of hunting for a perfect test, we set a confidence target and stack multiple forms of imperfect evidence until we close the gap.

If you’re navigating late-stage product development and want a calm, methodical way to move from 40% to 90% confidence, this framework will help you choose the next best step, allocate limited time and budget, and know when to stop.
