Joe,
Tautology, yes but just plain? Hummm... let's see is it the law of noncontradiction, or maybe the law of identity or.........
In any event, I have enjoyed the discussion. I think that we do have some points in common, however I do regret that I am not as eloquent in my rebuttals.
One final comment: Of course there is a difference in the percentage vs time spread analysis. My error in this discussion was in trying to over-simplify (considering the generalist nature of the forum) my case. Since the point was missed I have failed in my task - yes you can run Bivariate and or Partial correlations to the day ends but the result will not tell you the impact a 3 - 5 second variance in ASA will have on your staffing model. (One center or many, ARIMA model or simple moving average.) Let alone the impact on customer satisfaction.
Well, it appears that my envelope IS full now (I use 8 x 10 inter-office as my standard). I DO take call center metrics seriously, sometimes too much so. Oh well, as Deming said, "How could they know..............."
