Alexander,
Do you measure variation for agents and across agents? I am worried that what might seem like poorer performance from some agents will be within common cause variation. And if you are taking action on common cause variation - perhaps by doing some of the things you describe - you will be making things worse.
I only suggest this because you seem frustrated that what is happening is not improving performance, which if the variation was from common cause would be what I would expect to see. You can't blame the agent for what are common causes, you have to change the system.
If you are having trouble with what I am saying, send me the data in a time series for two agents, one with no problems and one with problems, preferably going back as far as you can for each. I will take a look and we can put up the results for the rest of CCV so they can see what I am talking about. Of course, make the data anonymous before sending.
Best,
