> Sure, you can spend the weeks to months of expensive and time consuming work it takes to get a fuzzy, half accurate and biased picture of what your users workflows look like through user interviews and surveys. Or you can look at the analytics, which tell you everything you need to know immediately, always up to date, with perfect precision.
Yes, admittedly, the first time you do these things, they're difficult, hard and you have lots to learn. But as you do this more often, build up a knowledge base and learn about your users, you'll gain knowledge and experience you can reuse, and it'll no longer take you weeks or months of investigations to answer "Where should this button go?", you'll base it on what you already know.
Asking users isn't a substitute for usage data.
Usage data is the ground truth.
Soliciting user feedback is invasive, and it's only possible for some questions.
The HN response to this is "too bad" but it's a thought-terminating response.
So if you don't want to spend the time doing that, or as is more accurate in corporate settings, the general turnover of the team is high enough that no one is around long enough to build that deep foundational product knowledge, and to be frank most people do not care enough.
This is why telemetry happens, its faster, easier and more resilient to organizational turmoil.
You seem to be interpreting my position as saying that one should only use telemetry to make decisions. Of course, no one reasonable would hold that position! What I’m saying is that only relying on user interviews without supplementing them with analytics would be knowingly introducing a blind spot into how you understand user behavior.
