What SOP / WI software is available?

I'm looking for software or app that makes creating work instructions or procedures easy. I've looked around and the types of programs that keep popping up are task managers like Trello. I've seen Simple Process but even that isn't what I'm looking for. I'd like to find a program that is designed more like "If this...Then that"or something similar. I'd also like it to be interactive and responsive. Currently our company is using Oracle information center to store Microsoft word documents with our instructions. I've googled this to death but I can never find the right words I guess. If there isn't something out there, I'd love to work with someone to build it. I know I'm being terribly vague and inarticulate. I just feel like I'm onto something here and it would be really helpful if I didn't have to reinvent the wheel on this one.
