Teaming refers to coordination and communication between people, often across disciplinary boundaries, to accomplish interdependent work. In contrast to static teams, teaming involves shifting group interactions and differing perspectives as work and tasks change over time. Teaming is especially important when work is complex, unpredictable, or requires collaboration with new or different people across organizational boundaries. During the COVID-19 pandemic, teaming has become a necessity for many kinds of work, requiring leadership to integrate diverse views, systematically examine options and implications, and make decisions to move forward.
