Documents are the results of our work and at the same time their raw material. They guide processes and contain our knowledge. A shared filing system provides a platform for team collaboration. This guide is aimed at IT project managers, specialists, and executives. It presents a modern structure for filing. Employees can immediately find any file and represent themselves without stress. No one has to wait for important data because they lack access. A good filing structure is a prerequisite for the implementation of document management software. Over 50% of all DMS projects fail because they are treated as purely IT projects. The motto of the guide is: "Intelligent software for intelligent structures - but not instead of intelligent structures." The modern filing system creates a stable framework for teamwork and opens up perspectives externally.
