Team members have reported poor sound quality during critical, time-sensitive conference calls. Which of the following may be a more effective means of communication?

One-on-one meetings eliminate the audio degradation and cross-talk issues inherent in multi-party conference calls by reducing the communication to two participants in a direct channel. For critical, time-sensitive discussions, this format ensures clarity, allows immediate clarification, and removes the technical bottleneck causing the poor sound quality.

A project wiki is an asynchronous, document-based tool and cannot replace real-time verbal communication needed for time-sensitive conference discussions.

Text messages are limited in bandwidth for complex, time-sensitive discussions and lack the verbal nuance required for critical project communications.

Social media is an informal, public-facing channel unsuitable for confidential, critical business communications.
