• My first paid computer-related job was the editing and hard copy production of an FAA-compliant operations manual for Aero Union Corporation of Chico California, in 1981...
  
• In 1983 the engineering drafting tables were set aside and replaced with NEC computers running AutoCAD, so disk file management, and file revision control were now a big deal. So I wrote a set of MS-DOS batch files that provided a way to "check-in" and "check-out" drawing files from our central Bernoulli Disk drive...
• Over the years since, I have undertaken many programming projects...

...Documents (usually a drawing) are easily looked up by part number or description, and displayed with ready links to all their related docs, such as sub-parts, next assemblies (used on), past revisions, authorizations, etc.

...Based on an open source web platform, with extensive custom programming, Perideo MPM is a highly effective means of tracking the needed data to assure that:

1. Sales Orders are entered correctly in accordance with what we promise to deliver
2. Raw materials are acquired or pulled from stock 
3. Production progress is tracked along the way
4. Shipping is carried out seamlessly
5. Invoicing is immediately executed
