Method of building 4 software engineering Project user experience

1 When do I start thinking about the user experience? Since the user experience and the user interface are so important to a project, but the designer who is responsible for this kind of work is not a software engineer, when will the designers join in as well? When do you think about it?

2. The development of technology will inevitably spill over into other aspects of society, such as morality. Can a website use a/B testing to affect the user's mood? What if it's for the purpose of "scientific experimentation"?

3. I've heard that there is a inflection point in a software project--before that, the number of new bugs is greater than the number of bug fixes, and after that, the number of bugs resolved is greater than the number of new bugs produced. So the curve of the bug moves down. Did we get to the inflection point of the mountain project?

4. Why are some successful companies not testing people?

5. How to measure the quality of software engineering?

At the beginning of this book, we talked about how to prove that we have done software engineering, developed a software that meets the needs of users, through a certain software process, in the expected time to release "Good enough" software and through data and other means to show that the software developed can be maintained and continue to develop, we can quantify the above mentioned points?
