My spouse is a workforce analyst. She schedules work packages for a large government agency. She's responsible for the workloads of about 150 people. All have been working from home for a full year, and yes, they are quite capable of doing it. However, overall productivity is down 30%. Since they have good data, she can clearly see which people are close to their normal productivity even when working from home, and which ones are considerably worse. Most people are worse.
