When a plan demands cooperation commanders will not give

Did the complicated Japanese plan in the Eastern Solomons make field miscommunication more likely?

Yes, because it required frequent coordination between commanders who did not get along or want to communicate.

A complex plan can work only when its participants exchange information reliably. The Eastern Solomons plan instead placed heavy communication demands on commanders who already had poor relationships. That design made friction inside the command structure part of the operation itself. No amount of detail in the plan could compensate for unwilling cooperation. A workable plan must fit the people and communications system that will execute it.
