The red/yellow/green coloring to me seems to imply that you want to be above average with these metrics, but I'm not sure that above average is necessarily a good thing here. Things like "response time", quicker is probably better, but "emails sent" — the two of the links from Mandatum had someone ending ~50 emails per day! It may very well depend on your job, of course, but to me, that's too much even to receive in a day (I don't want to read 50 emails.), and your email is going to be automatically sorted and likely ignored. "Contacts reached" also seems to imply higher is better, whereas I would think that more targeted conversations might be better. (But then, courtesy might demand CC'ing a list or a person in, so harder to say.) "Emails per conversation": taking more emails to conclude whatever is needed is better? Not meeting face to face if email isn't cutting it, or being clear and concise on the first email?
