‘Always over-deliver. This is how I won five Olympic gold medals,’ says Romanian gymnast Nadia Comaneci. As Leonardo da Vinci famously said, “ Simplicity is the ultimate form of sophistication.” Anything in life can be made horribly complex. Over-engineered. Confused and complicated. And this certainly is true for how individual performance is assessed. I have seen all kinds of matrices, grids, tables and complex readings. Abominations created to make a simple task more complicated. But the evaluation systems that work best, and make the most sense, always seem to boil down to three levels of performance. Three, and only three!
