Poor communication is a common challenge in group work, particularly when the group is large, diverse, or remote. This can lead to misunderstandings, confusion, errors, or delays, and can also affect the group's trust, cohesion, and satisfaction. To prevent or address poor communication, you should establish effective and consistent communication channels and norms. Choose the best tools and platforms for your group work, such as email, chat, video call, or project management software. Agree on how often you will communicate with each other, what information you will share and update, and follow the communication etiquette and expectations of your group and context. Additionally, communicate clearly and concisely with the group by using simple language and avoiding jargon or ambiguity. Provide relevant information without information overload or gaps, use visual aids to illustrate your points, and ask for clarification when needed. Finally, communicate positively and respectfully with the group by using a friendly tone without sarcasm or blame. Appreciate each other's work and input as well as give and receive feedback constructively. Express your emotions and opinions honestly but tactfully while respecting each other's differences and perspectives.
