There are three main subproblems to your questions: 1. Find out what users wants. The answer to that is research and the only book I have is Just Enough Research by Erika Hall. I also found Essentials of Business Research Methods by Joe Hair Jr. et al. 2. Build the thing that the user wants. That's mostly the real of Software Requirements and I have two candidates for you: - Mastering the Requirements Process: Getting Requirements Right by Suzanne and James Robertson - Software Requirements by Karl Wiegers and Joy Beatty. 3. Build something that the user likes and that he can use. That's UX and I have three candidates this time: - Observing the User Experience, 2nd Edition by E. Goodman and M. Kunlavsky - Understanding Your Users, 2nd Edition by K. Baxter et al. - The UX Book by R. Hartson and P. S. Pyla All of those just emphasize having an objective view of what you want to bring to the users and a rational execution strategy. I haven't read all so I can't judge them, but I believe they will give you enough starting points for you to devise your own method.
