The common approach to demand acquisition is to conduct customer interviews and discuss with your practice what problems you will encounter, and how do you solve them?

First, the question of "saying" and "doing" are inconsistent. Users often cheat us that the user is not intentionally deceiving us, but may be: they were asked the question they did not think carefully, and do not want to answer do not know, on the scene fabricated a plausible reason, or they have to please the interviewer's psychology, will answer them think you want to hear the answer, Rather than their own real ideas. In addition, we can also pay attention to distinguish between the facts and opinions of the user, in general, such as "What I do, how the steps, what problems encountered" the credibility of a higher degree of truth, and "I think, I think" this kind of view, you need to take big question mark to listen to. Second, the sample is small, the problem of sweeping. For this problem, I used a few of the following countermeasures. First of all, we should try to identify the various factors that may cause deviations, and in the report of the interview to indicate, let the reader understand. Then, in order to get the most accurate conclusion possible with as few samples as possible, I'll do the interview in an incremental way. For example, I'll interview 5 users first, draw a basic conclusion, then interview 5, see if there are any changes, and if there is a change, continue to increase the sample size, or think the question is appropriate? is the sample set appropriate? If there is no change, stop continuing the interview and save costs. The selection of samples, in fact, belongs to the category of probability and mathematical statistics, students who want in-depth can study on their own. Thirdly, the user is too strong to bring us to the ditch. To solve this problem, you need to always keep in mind the purpose of the interview. If you find that the topic is not correct, then quickly to the right, if found many times can not be pulled, you may consider the end as soon as possible, do not spend too much time on inappropriate objects. Of course, sometimes the user kan is very exciting, if you are not very busy, listen to long insight can also, this is self-grasp it. Four, we are too strong to bring users to the ditch. The solution to this problem is also to keep in mind the purpose of the interview and control your mouth.
