Value, Money, and Costs: The Ultimate Common Language for the Testing Strategy
summary
Central claim: frame testing as an investment that reduces probability and impact of failures and present costs in money. Builds a half‑day workshop mapping risks to ISO 2510 taxonomy where managers supply financial estimates (examples cited: $400M Knight Capital 2012, ~$10B CrowdStrike 2024, ~$60B Boeing 2024) and testing methods are mapped and prioritized. Uses Ackoff producer‑product perspective, a survey of 50 testers showing unit tests are overattributed, and an iterative review loop to reassess cost, probability, and effectiveness.
