The shape of an organisation, commonly known as its structure, is obvious to all those who encounter the enterprise. A new employee might regard structure as an imposed condition as soon as they are told to report to the manager. In a bureaucratic organisation most employees may associate structure with repetitive tasks and inflexible managers. In looser structures, innovative start ups or information technology companies, a career structure exists based on performance and flexibility, expertise and teamwork. Customers dealing with an organisation are faced by structure when they select goods to buy, or request a service to meet their needs. They may be seen by one employee, referred to a second, who it is thought can better satisfy their needs, and possibly charged for the service by a third. Every organisation operates within some sort of structure.
