The figure below shows two types of performance evaluation systems; one that measures individual performance and the other which measures team performance.
Even though the figure implies a causal connection between type of measurement system and quality of team output, as usual, I have no idea if a causal relationship exists. I suspect they are statistically correlated though, and the correlation is indeed as shown. I think the system on the left encourages intra-team competition whereas the system on the right catalyzes intra-team cooperation. What do you think?
