Software developers have the obligation to moral, professional have the responsibility to remind customers on these problems, and as far as possible to help them to solve these problems. In other words, software developers need to act as role similar to that of a doctor. We have a responsibility to help customers diagnosis currently known demand, and a effective prescription.
Of course, once the user demand, analysis collected finishing completed, commitment software specifications should be faithful for delivery to the customer. However, in order to ensure that software can safe and effective delivery, dangerous or poisonous demand must be removed, redundant and unnecessary demand need to allow the user to know, the potential can lead to demand growth of not clear place needs to be clear, quantitative. Users should be from software development technical team to get professional help, and should not be in demand on the collection and analysis of the passive role playing the observer.
Unfortunately, the demand of the defect and not through the common tests to eliminate. If needs to prevent errors and appear, or haven't been able to through the regular inspection or other methods to eliminate, then, from the demand structure created test cases can only confirmed that demand the right, but not find the mistake. (this is why many years of software testing never discover and eliminate "2000")
Another type of demand, for some new creative software applications, probably the first user only original person, not the second one. Reference some successful software history, such as APL programming language, the first spreadsheet software, the early Web search engine (later become Google).
These revolutionary application software are all inventor himself used to solve their own problems. They are not in accordance with the conventional concept of "user needs" developed. Unless the demo program is development completed, others basic can't realize the software value of invention. Therefore, "customer demand" for some new revolutionary software is not fully applicable, unless they have been released.
