Collaboration and cooperation both involve working with others.
Collaboration requires close interaction. People combine their skills and efforts to achieve a shared objective and are mutually accountable for success and responsibility.
Cooperation focuses on sharing resources, assisting others, and completing individual tasks that contribute to a broader objective. It does not involve merging skills or sharing accountability. Cooperation can support different objectives aligned with a mission designed to fulfill a vision.
In essence, collaboration is more integrated and intensive than cooperation.
