WorkMeter

This is the best way to measure and diagnose PRODUCTIVITY for TEAMS. There is no product like this in the web, since it has strong metrics and it is aimed for a professional use for consultants more than a single use. RescueTime is good but WORKMETER is the king of the metrics, KPI and how it was built.

The main difference with RescueTime is that this software you can use it for your consultant business more than to expect improve specifically the productivity of the people.
