Cross-functional teams are groups composed of members from different departments or areas of expertise within an organization. These teams collaborate to achieve a common goal, leveraging diverse skills and perspectives. For example, a team might include members from marketing, engineering, and customer service to develop a new product. The primary advantage of cross-functional teams is their ability to foster innovation and improve problem-solving. By bringing together individuals with varied backgrounds, these teams can address challenges more effectively and create solutions that consider multiple viewpoints. This collaborative approach often leads to increased efficiency and better outcomes for projects.
