Fiedler's leadership model is determined by whether a leader's style is task-oriented or relationship-oriented and if that style is effective for the situation at hand.

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.
