It’s usually obvious that certain people contribute more to a group’s success than others. Perhaps there is a way that the KM contributions of individual or key participants could be measured using an “adjusted plus/minus” rating, such as used in professional basketball, for when they are active vs. not. Some people do have the ability to lift the participation in and effectiveness of an overall effort just by participating. This might be a way we could assess overall KM effectiveness, as well as reward the people who may not be the “big names” but are important contributors and tend to stay in the background.
