Berlo's SMCR model is a communication framework that outlines four key components: Source, Message, Channel, and Receiver. Developed by David Berlo in 1960, the model emphasizes the importance of each element in the communication process. The Source is the originator of the message, while the Message is the information being conveyed. The Channel refers to the medium through which the message is transmitted, and the Receiver is the individual or group receiving the message. The effectiveness of communication depends on the interaction between these components. A skilled Source can enhance the clarity of the Message, while the choice of Channel can influence how well the Receiver understands it. By analyzing these elements, communicators can improve their strategies and ensure that their messages are effectively delivered and received.
