Gathering feedback from your users is a crucial part of any design process. The way in which you can gather this feedback varies depending on what kind of questions you are trying to answer, the resources you have available for user research and at what stage of the product life cycle you are currently in.

You know that user feedback is crucial — after all, your users will decide whether your app succeeds or not — but how do you know whether users are being fair and objective in their feedback?
We can tell you: They won’t be. All of your users will be giving you biased feedback. They can’t help it.

Up-front user research is comforting because it hands off the responsibility of making decisions. Any time a difficult decision needs to be made, designers and product managers can simply refer to work that was done months ago (which is potentially now irrelevant). The research can act as a safety net. If the product or feature doesn’t work out after launch, the team members aren’t responsible; they were simply following the research. But research can give teams a false sense of security–a feeling that they’re not making the decisions, that the research has predetermined what will happen.
Here’s the thing: In the best companies in the world, the companies that make the products everyone uses, a huge amount of the “innovation” comes from simply making assumptions, building something, testing it, and iterating based on real user feedback. Do you think that Slack came about after a lengthy discovery phase? How about Google Hangouts, Gmail, or the Kindle?
