Right. But spreadsheets and "shadow IT" aren't really about technology - they're about autonomy, about how the organization is structured internally. No one is choosing a bad process from the start - spreadsheets are the easiest (and often the only possible) way to solve an immediate problem, and even as they turn into IT horror stories, there usually is no point at which the people using it could make things better on their own. The "quality solutions", conversely, are usually top-down and don't give users much control over the process - instead of adoption, this just breeds resistance.
