Confidence is a Dial: Turn It with Evidence, Not Guesswork

We turn late-stage design surprises into a strategic plan by assigning explicit confidence levels, stacking evidence, and using the three-dial model of time, cost, and confidence boost. We show how to work backward from a system test to cheaper steps that drive faster, clearer decisions.

• applying the three dials of time, cost, confidence
• sequencing with the work-backwards strategy
• avoiding overtesting, undertesting, wrong testing
• turning confidence into a team communication tool
• practical next steps to build the confidence muscle
