Credo is a Latin word, which the Oxford English Dictionary defines as "a statement of the beliefs or aims which guide someone's actions."
In the corporate world, a credo is similar to a company's mission statement, its beliefs, principles, or purpose. A company's website likely will contain a prominently displayed mission statement, along with the firm's goals and objectives.
In the best possible world, a company would use its credo to guide its actions.
