There are advantages and disadvantages of the matrix structure. Some of the disadvantages include tendencies towards anarchy, power struggles and 'sinking' to group and division levels. Matrices increase the complexity of the chain of command, which can present problems because of the differentiation between functional managers and project managers. This, in turn, can be confusing for employees to understand who is next in the chain of command. An additional disadvantage of the matrix structure is higher manager to worker ratio that results in conflicting loyalties of employees. However, the matrix structure also has significant advantages that make it valuable for companies to use. The matrix structure may improve upon the "silo" critique of functional management in that it aims to diminish the vertical structure of functional and create a more horizontal structure which allows the spread of information across task boundaries to happen much quicker. It aims to allow specialization to increase depth of knowledge and allows individuals to be chosen according to project needs.
