Back to how I worked before our company got it's first PC in 1987, but not ethernet until 1998.
Drive around talking to people, phone, hand written letters, Spirax #561 paper notepad.
(GTD device: write in a reminder chronologically, cross it off when done)
Productivity = work/time will tank.
My 1990's employer didn't network our PCs as the boss thought we'd be 'cyberbludging'.
This was probably fair, but the spare time we gained through IT productivity far outweighed any increased loafing.
An important gain preemptive action, you can now 'cut things off at the pass' before you could drive there.
