Here's a saying you may have heard. It's new to me though. A million drills are sold every year, but not one person wants a drill. What they want is a hole. Useful to bear in mind when trying to decide on what your new software should actually do. Of course it doesn't do to take it to extremes, otherwise it becomes unimplementable, you'll end up with life, liberty and the pursuit of happiness as part of your requirements.
