I guess you mean that now people make forms or documents then wither email them or they print sign and scan and send the same. Instead they could have some ERM system that supports the same functionality by just filling forms in the web ui, clicking approve buttons etc. Problem is those won't support the exact thing they need and a docx is editable to say just what you need (getting the erm provider to add a new checkbox is expensive and needs ongoing maintenance subscriptions), and often wet ink signatures are required by law.
