software adapted practices that were well established in industrial manufacturing and design, way before computers , espically regarding technical documents and drawing desings ( they had different , hierarchical maps with an indexing numbering system)

original version control systems used the exact same principles :
- checkout / checkin => file locks
- unit of work was individual files (like drawings) (it was not not hierarchical such as folders or projects )
- central “repo” (mainframe , later servers)
