The crucial role of communication processes in the day-to-day functioning of Air Force personnel is abundantly evidenced via the myriad of interactions that, taken together, result in mission effectiveness and vision for future endeavors. Such processes occur on the interpersonal, group, organizational and mass levels. From the staff sergeant who is interacting with fellow airman about the best way to approach a task to the Air Force Chief of Staff conveying his/her vision regarding future directions for the Air Force, communication processes are the foundation for meanings to be conveyed and for shared understanding to occur. This book is intended to be a guide, at all levels of the Air Force, for the improvement and enhanced understanding of these communication processes so that we (as individuals, groups, organizations & a military branches) can benefit from interacting effectively in Air Force environments.
