This episode accompanies Module 3 of the course, which is all about acquiring evidence from practitioners – people who have experience with the problem we are tackling, or the solutions we are considering.

Modules 3 and 4 are somewhat intertwined, so the rest of the discussion about practitioner evidence will be in Episode 4. In this episode we consider the choice of practitioners (people with expertise, not just opinions) and how we gather information from them. Asking questions (the focus of Module/episode 2 is critical here, and emphasis is again put on not jumping to solutions, even though it’s so tempting!

There is also discussion about the use of questionnaires – including some guidance about where to start (at the end) and how to get the best results - keeping the questions simple, testing understanding of the questions before launch and ensuring you know exactly how you’re going to use the data.
