Some people (especially those professionally involved in operations management!) argue that operations management involves everything an organisation does. In this sense, every manager is an operations manager, since all managers are responsible for contributing to the activities required to create and deliver an organisation's goods or services. However, others argue that this definition is too wide, and that the operations function is about producing the right amount of a good or service, at the right time, of the right quality and at the right cost to meet customer requirements.
