I know this isn't the enterprise crowd on HN, but this idea is pretty deeply rooted in a lot of large organizations in the form of "Business Process Management". The BPM vendors all pitch the "let business users create software" promise. In reality (as others in the comments have said about similar tools) it's very hard to deliver anything but the simplest applications and maintain the ability for non-developers to grok what's going on.
