In this episode, Adrian is joined by Renaud Anjoran to explore fail-safe design principles: essential thinking for anyone developing most kinds of products.

Through real-world examples ranging from Tesla doors to Boeing and consumer electronics, they highlight how designers must ask: “If this fails, what happens to the user?”

They break down why it matters, what trade-offs exist, and how structured risk analysis, simplification, redundancy, and error-proofing can dramatically reduce hazards and costly failures.
