The fiction in most measurement systems is that individual performance measures assigned to individuals presumably reflect the effort and skill those people used in doing their jobs. But individual performance in an interdependent system will always be difficult or impossible to measure. Individual performance and behavior, even if they could be accurately assessed, are the result of many things over which the person has little or no control, as the above example nicely illustrates.
maybe organizations could learn from measures such as TrueSkill, where results are measured at the group level, but every individual gets a personal score based on their involvement in different groups
