It would be useful to at least know a little bit about the type of customer the products were for.

There was a story a while ago from someone who had built software for physicians to pick the best drugs for a particular diagnosis. They described the problem and how it was currently solved. They described how they talked to doctors and what response they got. They described what they had to do to create a useful and credible product. I found that post very enlightening.

With this post I feel like I have absolutely no way to judge whether the author's conclusions are relevant to my own projects.
