Engineering rework often comes from unasked questions or using the wrong tool at the wrong fidelity.
Dianna outlines three common prototyping traps:
- the “ta-da” trap, where teams build polished prototypes to impress stakeholders before the concept is stable, anchoring the team to an early solution
- the “I’m smarter than cardboard” trap, where engineers skip low-fidelity physical models in favor of analysis even when the real question is usability
- the “validation theater” trap, where teams default to expensive, validation-level rigs before confirming they’re asking the highest-risk, right question.
All three share a root cause: jumping from idea to build without defining what must be learned and the appropriate fidelity.
She invites listeners to subscribe for a future episode on prototyping done well.

Work with Dianna
I provide independent quality engineering, product-assurance, and technical-risk support when product or process decisions need experienced outside scrutiny.
My work includes:
- Quality-system and product-development method reviews
- Technical evidence and standards-based rationale
- Independent risk and readiness reviews
- Project-based and fractional quality advisory
