When managing a global program with distributed teams, videoconferencing is the most effective means of team interaction. It allows for visual communication, real-time collaboration, enhanced engagement, and relationship building. Videoconferencing enables team members to see each other, which is crucial for non-verbal communication cues such as facial expressions and body language. This enhances understanding and rapport among team members. Real-time collaboration is facilitated, allowing for discussions, screen sharing, and document collaboration simultaneously. Engagement is maintained by creating a sense of presence and connection, reducing distractions, and encouraging active participation. Building relationships is also vital, especially when working with distributed teams, as it helps mitigate challenges of cultural differences and time zone variations.
