Let's say the new remote workers were processing accounts payable. The very nature of their work will be accountable and thus there isn't a NEED for the claptrap the article's author recommends. Indeed, Zoom meetings etc actually get in the way of work but reinforce the boss' self-importance.
If the work isn't like that of the payables processor, then the boss shoild have built in a way of assessing progress. BEFORE the pandemic. This also means, by proxy, the boss had a way of proving THEIR value to senior management. The fact that your people aren't centralized in the hive doesn't mean you need to suddenly call into question their private work ethic or establish busy work to show how important you are to your bosses.
I agree with caveats. In the hands of the Dilbertonians, PowerPoint is IQ reducing. In the hands of someone with skills, it's great for flowcharts and such (even better than Visio) to really break out processes that you'd never bother the Dilbertonians with.
