Improving Testing Quality by Changing Culture
summary
Claim: reduce escaped defects by changing culture rather than hunting bugs. Evidence: Deming/Toyota-style quality built in, Google’s Project Aristotle finds psychological safety the top predictor of team performance, and a Puppet Labs DevOps survey of ~5,000 respondents shows highly engaged firms grow revenue 2.5× and report fewer defects. Concrete practices: continuous delivery and CI, shifting testing left, mobbing/pairing, using NPS or social badges to measure engagement. Outcomes reported: faster learning, less rework, improved quality and retention.
