Chief operating officer
Unlike the CEO position, which is generally thought of as the most important person in an organization, the COO position's name and job description (something described) is usually linked to what the CEO's job is. The selection of a COO is similar to electing a person like the Vice President or Speaker of the House: the more power and responsibility the position holds, the more experience and trust required to get hired to be a COO. There can be more than one COO in a company, such as a company which supplies roofing tiles, or an organization that makes clothes. Companies that make or refine goods naturally need more COO positions.
