So how do I evaluate 'Be all you can be'? Or what do you think would be a useful way of evaluating performance?
You'd need to see if people are more efficient without the setting of targets. Measure with, measure without, look at outcomes.
You also need to trust people to know what they need to do in order to work efficiently. I find this at home; my eleven year old needs me to keep an eye on his school work because he doesn't yet have the skills to self organise, whereas my fifteen year old knows far better than I do what she needs to do, when and how.
