My guest is David Bland, author of the bestselling book Testing Business Ideas co-written with Alexander Osterwalder and part of Strategyzer's book series.

David is one of my biggest references in Product.

His work, combined with Teresa Torres, is such a potent cocktail for anyone wanting to build better products and discover value more effectively.

One of the things I love about David's work is his emphasis on evidence-based decision-making and how practical he made it for teams to adopt this mindset.

We talked about:

- How to map your assumptions and which risks to consider first

- Why working collaboratively and across various areas of the business is so important when testing desirability, viability, and feasibility

- Why you should start discovery with a small and 100% dedicated team, and expand as you generate evidence

- How desirability and viability are intertwined, and how to go about de-risking it

- How to frame hypotheses

- How to evolve your evidence from what customers say to what they do (going beyond interviews and surveys)

- How to sequence experiments and get the right balance between running 1 experiment and planning ahead

- How to test willingness to pay

- Characteristics of high-performing teams doing discovery

- The importance of time-boxing and connecting it with how the company makes decisions and approaches funding

- How leaders can foster a culture of discovery
