Berlo's SMCR Model is a communication framework that outlines the essential components of effective communication. SMCR stands for Source, Message, Channel, and Receiver. The model emphasizes that the source must be credible and skilled in delivering the message, while the message should be clear and well-structured. The channel refers to the medium through which the message is transmitted, such as spoken words, written text, or digital media. Finally, the receiver is the individual or group who interprets the message. Understanding these elements helps improve communication effectiveness in various contexts, including personal interactions and professional settings.
