Of course a File Plan and a Taxonomy are not the same thing, but I bet that title got your attention! Although, I would bet that many folks from the Document Imaging industry do not really understand what a File Plan is, because most of the time Records Management is outside the bounds of what they are implementing.
Isn't it fun to have a new gig? My new gig is being a student of Information Governance. I have been in the Document Imaging industry for over 20 years and have spent countless hours analyzing and building Taxonomies. But the concept of Information Governance is something we avoided, or maybe not avoided, but certainly didn't embrace.
