Communication breakdown is when there is a lack of, delay in, or misunderstanding of communication between you and your customer, or within your project team. This can result from different communication styles, preferences, channels, or languages, or from distractions, interruptions, or conflicts. Communication breakdown can cause confusion, errors, delays, or disputes in the project, and erode your customer's confidence and satisfaction. To prevent communication breakdown, you need to establish and maintain clear and consistent communication with your customer and your team. You need to identify and use the most appropriate communication methods, tools, and frequency for the project, and tailor them to your customer's and your team's needs and expectations. You also need to listen actively, ask questions, clarify assumptions, confirm understanding, and follow up on action items.
