Throughout this book, communication has been treated not as the exchange of information, but as the process through which teams make meaning together. This definition, grounded in the work of Weick (1995) and Pearce and Cronen (1980), recognizes that communication is how teams interpret evidence, negotiate priorities, surface assumptions, and coordinate action across roles, tools, and time. It is the mechanism that allows individual expertise to become collective reasoning. When communication functions effectively, teams can work together more efficiently. When it weakens, individuals revert to private interpretation, and collaboration begins to fragment.
