question on operation management

Operations management is an area of business that is concerned with the production of goods and services, and involves the responsibility of ensuring that business operations are efficient and effective. It is the management of resources, the distribution of goods and services to customers, and the analysis of queue systems.

APICS The Association for Operations Management also defines operations management as "the field of study that focuses on the effectively planning, scheduling, use, and control of a manufacturing or service organization through the study of concepts from design engineering, industrial engineering, management information systems, quality management, production management, inventory management, accounting, and other functions as they affect the organization" (APICS Dictionary, 11th edition).

Operations also refers be the production of goods and services, the set of value-added activities that transform inputs into many outputs.[1] Fundamentally, these value-adding creative activities should be aligned with market opportunity (see Marketing) for optimal enterprise performance.
