The law of barrels in management theory is that how much water a bucket can hold depends entirely on the shortest board. This means that any organization may face a common problem, that is, the parts that make up the organization are often excellent. Inferiority, and the disadvantaged part often determines the level of the entire organization. The law of barrels and the law of wine and sewage are different, the latter discusses the destructive forces in the organization. Can't deduce from this text? ['The shortest wooden board in barrel law is a useful part of the organization.', 'The shortest wooden board in the law of sewage is a useful part of the organization.', 'The shortest wooden board according to the law of barrels is less useful than the other parts.', 'Strength is only relative and cannot be eliminated, the question is whether you can tolerate.']
