A functional structure groups employees by their skills and expertise. While it provides specialization benefits, it can cause communication, measurement, location, customer, and strategic problems as the organization grows. Managers can address these control problems by redesigning the structure to improve integration between functions. As organizations diversify their products, locations, and customers, they often adopt divisional structures like product, geographic, and market divisions to better align the organization with these demands. Matrix and network structures provide alternative approaches to balancing functional and divisional coordination needs.
