A cross-functional team is a group of people with different functional expertise working toward a common goal. It may include people from finance, marketing, operations, and human resources departments. Typically, it includes employees from all levels of an organization. Members may also come from outside an organization (in particular, from suppliers, key customers, or consultants). Cross-functional teams often function as self-directed teams assigned to a specific task which calls for the input and expertise of numerous departments. Assigning a task to a team composed of multi-disciplinary individuals increases the level of creativity and out of the box thinking.
