Now I get it why we failed the first time. What we were defending was a part of the EDM System, definitely. However, it was only a small part of it, namely data storage and distribution. What an EDMS constitutes a workflow following the creation until the disposal of the document. Thus including, versioning, document searching, security and management of these documents.
However, I still don’t get how we can pass this time. Looking and understanding concepts are difficult to find.. But if there’s a will, there’s a way so just go!
