Is your leadership team a shark tank, a petting zoo or a mediocrity? A shark tank is overly competitive and ruthless, sometimes selfish and political. A petting zoo is too nice and accommodating. People avoid conflict and disagreement. A mediocrity is not a bit of both the previous types, but a lack of both traits. It is not brutally honest enough, yet people do not care or support one another enough either. It is complacent and indifferent.
If you find your leadership team in any of these modes, it is time to think hard what kind of leadership team do you really want to have. Expected behaviours and unacceptable behaviours must be communicated. Build the right culture in your leadership team, and they will build the right culture for your company.
