The fault may sit with the receiver
Berlo’s SMCR model decomposes communication into Source, Message, Channel, and Receiver so failures can be located across competence, design, access, coding, and social context
Premise
A communication problem rarely lives in wording alone. David Berlo’s SMCR model creates four immediate points of inspection: Source, Message, Channel, and Receiver. Its familiar four-box appearance understates the human detail inside the framework. Both source and receiver carry skills, attitudes, knowledge, social system, and culture; the message has content, elements, treatment, structure, and code; channels are sensory routes.
That decomposition is useful before intervention. A technically accurate announcement may fail because the source lacks credibility, the code assumes specialist knowledge, the channel is inaccessible, the required action is buried, or the receiver’s social context makes the request illegitimate. Rewriting the sentence fixes only one possible constraint.

Model
In this series, Model names the editorial family primarily used to understand and explain communication: theories, frameworks, effects, traditions, principles and other conceptual resources. It is an umbrella for a route into the field, not a claim that every included object is a predictive model.
Editorial orientation · Category
Analytical Frameworks, Typologies & Heuristics
Organizes dimensions, distinctions, types or questions so that a situation can be examined systematically. A framework supplies structure, a typology distinguishes forms, and a heuristic offers a usable way to orient judgment.
