One of the first mistakes a new manager makes is to use just one data point or one input to come to a conclusion. It could be a personnel decision, or an operations decision, but in any case, you cannot get an accurate assessment if listening to only one source. Because Dick says something about Betsy, for example, doesn’t mean that it’s true–there are always at least two sides to every issue and every problem. I see this all the time in my consulting work. Even top managers can get riled and jump to conclusions before knowing the complete story. While corporate life can get messy and its sometimes difficult to reconcile legitimate and conflicting functional objectives, improper political agendas and even spurious ego-driven aggressions make it far worse. The quality of a leader and the culture make all the difference, for better or for worse.
