The three Cs of teamwork are communication, cooperation, and collaboration. Communication is key to ensuring team members are on the same page, have a clear understanding of goals and expectations, and can openly share ideas and feedback. Cooperation involves each team member being willing to work together towards a common goal, being flexible, and offering support to one another. Collaboration is the act of working together to achieve a shared objective, utilizing each team member's strengths and abilities to create a cohesive and efficient team dynamic. Without these three elements, a team may struggle to be successful in achieving their objectives.
