Answer:
Fiedler's contingency leadership model is determined by this.
Explanation:
Fiedler's Contingency Theory suggests that an individual's efficacy as a leader depends on how his/her leading style goes with the situation.
We can see it in this case; the leadership model is determined by how the leader's style (whichever orientation it has) is effective towards the situation being presented to him/her.
There can be other factors that come into play, such as one's personality, the nature of the task and the group in general.
