Ah, the joys of capacity planning....
For a time in the 1980's, I worked at the now long departed Naval Shipyard in Long Beach, CA,
(victim of the Base Realignment Act and Closure - BRAC of 1995) in Code 249, Computer Applications Branch of the Planning Department (engineering). My boss tasked me with writing the justification paperwork and approval coordination to purchase office automation for the supervisors, engineers and engineering techs.(Then it was MS-DOS and IBM PC-AT clones.)
We received zero support from the IT department. Our budgets worked differently and to them we were an unnecessary bother. In the multipart paragraphed request was:
DESCRIBE CURRENT AUTOMATION: I described our office automation as telephones, Xerox copier, pens and pencils, notepads, hand calculators, 3 ring binders, file folders and cabinets, wall calendars, wastepaper bins, and etc.
For initiating approval, I went to the IT Department two floors down and punched the nicotine riddled "specialist" in the Winstons with my paperwork. He sat down at his desk, started flipping through the paperwork. When he read the paragraph on our current situation, he turned beet red in the face and blew up.
Dilbert fashion I quietly excused myself, told him to let me know of comments or signature approval of his supervisor. It got approved.
This reminded me of your comment,
"the joys of capacity planning."
