Step-by-step explanation:
The characteristics of a communicator who prefers to hear about big-picture ideas are best described as visionary. A visionary communicator focuses on overarching goals, concepts, and future possibilities rather than the minutiae of a situation.
While detail-oriented individuals pay attention to specifics, and analytical people delve into the data, a visionary looks at the broad scope of an idea or plan. Strategic communicators might also think in terms of large-scale planning, but they are often more involved with the specific strategies that can turn a vision into reality.
