The model that requires a manager to assess her own style and her situational control is "Fiedler's contingency model".
The Fiedler Contingency Model was made in the mid-1960s by Fred Fiedler, a researcher who contemplated the identity and qualities of pioneers.
The model expresses that there is nobody best style of initiative. Rather, a pioneer's adequacy depends on the circumstance. This is the aftereffect of two components – "leadership style" and "situational idealness" (later called "situational control").
