Too much too fast
Paperless by 2020? Far too much to do in far too short a time.
Why not do it sensibly? Look at how things are done and split it all up into small projects. Determine a framework for how all that will fit together. And finally, start one of the projects.
Once that one project is finished, move onto the next.
The problem that big IT projects seem to have is they do it all at once. So, everything goes horribly wrong and the entire thing fails miserably, rather than one small part of it being a problem.
