False. One possible downside is losing a competitive edge in the market. If competitors know what you are going to develop next, they may anticipate in that regard.
Possible concerns are that some users or groups of users are more vocal than others, which might result in a difference between the general opinion and the opinion that is heard. Also, feedback on a public roadmap is most likely coming from existing users only. While it is important to retain those, prospects might not comment on your roadmap with features they are missing.
Two examples that are discussed in this chapter are sentiment on social media channels and the number and severity of support requests.
Answer number 3 is correct. A hypothesis states a belief that a certain feature is needed – the hypothesis. The second part is a measurable user response that is to be observed before the belief is confirmed. This is called the confirmation threshold. A hypothesis does not yet have a conclusion.
Possible benefits of user interviews or focus groups are that they are often conducted at a smaller scale, allowing not only for the measuring of feedback, but for also understanding the reasons behind it. Another benefit is that participants can be carefully selected to be representative of all users or a particular segment.
