This sounds contrived to me.

If you know whether people actually delivers or not, this is an easy discipline issue: point out that you know, and that working from home is a privilege that will be withdrawn if performance slips.

What I tend to find is that managers often believe productivity is higher in the office because they see people engrossed in their computers, without seeing what people are actually doing, and believe they're in control.

If you think you need a high touch system to handle this, then it suggest you doubt your current systems ability to pick up actual performance vs. whether they look busy.
