Hershey Blanchard theory is a situational leadership theory. It combines leadership behavior with follower behavior. It is also referred to as Situation Leadership Theory.
First we start of with a two dimensional chart again, which characterizes leadership into four different styles:
S1: Telling
S2: Selling
S3: Participating
S4: Delegating
Then Hersey-Blanchard adds a second dimension by adding the follower behavior to it. These categories are:
R1: unable and unwilling
R2: able but unwilling
R3: unable but willing
R4: able and willing
