What process to use?

For a change I will talk briefly about process matters today. I'm really not a process guy,... but I've heard it said over and over again and I think I can see it in my own past and present projects as well. The process that is used doesn't matter too much. What really matters is to talk a lot with the customer. Understand each other. Use transparency and instant feedback. That will give good result, no matter which process is used.
