A Chief Operating Officer or Chief Operations Officer (COO) is a corporate officer responsible for managing the day-to-day activities of the corporation. The COO is one of the highest ranking members of an organization, monitoring the daily operations of the company and reporting to the Board of Directors. The COO is usually an executive or senior vice president.
The chief operating officer is responsible for operations management (OM). The focus of the COO is on strategic, tactical, and short-term OM, which means he or she is responsible for the design, operation, and improvement of the systems that create and deliver the firm's products/services. Managers need to understand the real work behind the company's core operations, and the buck stops with the COO, whose primary concern is operations improvement. The duties of the COO may reside in certain organizations with a Vice President of Operations.
