Why Your 'Correct' Discovery Method Might Be Wrong
Why Your 'Correct' Discovery Method Might Be WrongDear Reader, "Which experiment should we run next?" This question comes up in almost every Discovery coaching session I facilitate. Teams often focus on finding the methodologically perfect way to test their assumptions. But here's the thing: the most technically correct experiment isn't always the right one to run. When choosing methods for Product Discovery, we often focus on what fits our research question or assumption best. Say you want to understand how users perceive features in your product. A diary study might be the perfect method—capturing real usage patterns over time. But what if it takes three months to get reliable insights? A series of well-structured interviews or shadowing sessions might get you 80% of the way there in just two weeks. Several factors determine your lead time to insight:

But depending on your traffic and conversion rates, it could take weeks or months to reach statistical significance. In contrast, while recruiting participants for qualitative interviews might take two weeks, you could have reliable insights within days of completing them. Neither method is inherently better. What matters is the total time to reliable insight, not just how quickly you can get started. So, when picking your next Discovery priority, ask yourself:
Here's a practical tip: When evaluating lead time, avoid abstract scoring systems. Instead, estimate the actual duration by adding:
