I avoid phone calls but analyze: would calls be more efficient? Map communication: back-and-forth email vs. single phone call. Calculate: if 10 emails take 30 minutes but one call takes 10 minutes, should I call? Show me the call advantage: faster resolution, less back-and-forth. Give me the calling rules: call for these situations, email for these. Include: when calls are more efficient than email, whether phone avoidance is wasting time, and how to use calls strategically.
