You unintentionally perform faster than usual when being timed

One of the things that takes some getting used to in a Lean organization is the fact that people are constantly watching each other. Leaders are relentlessly told to go to gemba. Teams participate in a never ending parade of kaizen activity. Employees from other work areas visit to do benchmarking and get ideas for best practices. In a nutshell, if you work in the company with a culture of continuous improvement, you will be on display.

The truth is it does not take long to get used to this sort of openness. After all, everybody is in the same boat. You are the observed person one day and the observer the next.

The issue that lingers, though, is that people have a tendency to change their pace of work when they’re being watched. If you watch someone for only a short time, there is a better than average chance that you are not seeing the work being done as it normally is.
