Is your light still on? Reading notes 3

Where does the question come from in the fifth chapter?
When we meet a very urgent and very important problem, we will not have an effective way to solve it 1:30, then we should find the source of the problem, it may bring us inspiration. And, if we don't know where the problem comes from, we're likely to put the cart before the horse, often making things worse or causing more thorny problems. For example, a project, the user's needs and the team's technical problems, if we simply want to use technology to solve the problem, it is often spent a lot of resources but caused more problems.
The sixth chapter expresses the content is very true, some problems exist, but people often do not want to solve, it is equal to say that it does not solve the value. This is a very real problem, and people spend months or more to solve it and find out that it doesn't have to be solved at all. So when we analyze things, we need to know all the time, whether people want it to change in a good place, or that the key people want it to change.
This 53-page book has been read, how to say, I can only say impressive, perhaps because it is short, it is more than the 300-page dream break code also impresses me. The analysis of the problem in the book is of great help to us in our study and future work, and it can influence our future, I am glad I chose it.
