Our metric is how many people have completed their certification within six months of signing up. We want that metric to be 97 percent. While we would love to have 100 percent as our metric, that is not realistic (unforeseen circumstances do happen, such as life events). And aiming for 100 percent means that we would be in a constant red flag situation. Oh, no, we are not at 100 percent again, what happened? Since it is unachievable, we will never get there, which means we will begin to ignore it.
