We had a potential client come in saying they had the toughest requirements; terabytes of data would be collected, we'll need PhD data scientists to write very complex algorithms, huge servers to handle the incredible load and uptime needed, full suite of mobile and desktop apps, blah blah blah.
We analyze his requirements a bit and it turns out he needs actually just needs a survey with 5 questions, none of which collected personal information. And he treats 20 patients a year. We call him in, set him up a Google Form in front of him, and sent him on his way. Probably saved the Canadian healthcare system millions on that one.
Looking back on this experience, I think some people are incredibly ego-driven, so the prospect of doing something off-the-shelf or for free doesn't enter their conscience.
