Hm, now that I read well, I feel this research group does too much &quot;snapshotting&quot; of dynamics. Groups not performing well could have had their &quot;norms&quot; subjected to a harsh external force, such as, say, performance reviews, hire &#x2F; fire &#x2F; downsize &#x2F; layoff, etc.<p>And where is the discussion of sociopathy and other classic psychological manipulations? You&#x27;d figure that subtle disruptors would be critical to the study, since I argue that middle management collapses in most large organizations due to the Machiavellian predilections of petty power brokering.
