This organizing of specialization leads to operational efficiency, where employees become specialists within their own realm of expertise. On the other hand, the most typical problem with a functional organizational structure is that communication within the company can be rather rigid, making the organization slow and inflexible. Therefore, lateral communication between functions becomes very important, so that information is disseminated not only vertically, but also horizontally within the organization. Communication in organizations with functional organizational structures can be rigid because of the standardized ways of operation and the high degree of formalization.
