While there are myriad organizational designs, also called organization structures, there are a few underlying fundamental forms. These are tall vertical, flat horizontal, functional, product, matrix, and simple. Other forms, like boundariless and autonomous internal designs, fall withing these fundamental designs.

A disadvantage with horizontal, in which authority lies with the consensus, is that goals may debated and diluted.
