People are individuals, but just the act of watching someone who is engaged, inspiring, transformational, and positive will translate to the subordinates because they can see that this is the expected norm. If coached and mentored correctly, personnel often manage to reach a high bar because they are interested in doing well unless there is a factor which causes them to do otherwise.
Like it or not, organizational values define organizational culture. These values help guide you in times when hard decisions must be made under ambiguous situations. When organizations lack defined values, or personnel don’t understand them as the gospel truth, they don’t always reflect those values when challenged.
