The fact that none of the companies can do it, means WFH is a massive productivity failure. The reasons are aplenty
- Self-Reporting Employees or Researchers simply can't measure productivity that matters.
- WFH research is typically done and funded by WFH-friendly entities skewing it's benefits. There are no neutral social science research.
- Startups, which are a better unbiased WFO/WFH study (because all startups have the same starting conditions allowing us to control more variables), clearly show that teams (both technical and sales) sitting in room can crush/outrun Startups that are remote-only.
- Productivity measures done by these studies are almost always individual, but team productivity and firm productivity are emergent properties and hard to measure
