Differences between Unity of Command and Unity of Direction

Basis	Unity of command	Unity of direction
Meaning	It implies that a sub-ordinate should receive orders & instructions from only one boss.	It means one head, one plan for a group of activities having similar objectives.
Nature	It is related to the functioning of personnel’s.	It is related to the functioning of departments, or organization as a whole.
Necessity	It is necessary for fixing responsibility of each subordinates.	It is necessary for sound organization.
Advantage	It avoids conflicts, confusion & chaos.	It avoids duplication of efforts and wastage of resources.

Therefore it is obvious that they are different from each other but they are dependent on each other i.e. unity of direction is a pre-requisite for unity of command. But it does not automatically comes from the unity of direction.
