Cannikin Law in management theory states that how much water a barrel can hold depends entirely on the shortest piece of wood  This means that any organization may face a common problem, that is, there are pros and cons of the various parts of the organization, and the inferior part often determines the level of the entire organization
Cannikin Law is different from Wine and Sewage Law, and the latter discusses the destructive power in the organization
The shortest piece of wood in the Cannikin Law is less useful than other parts.
