<P> The model organizes the "scientific study of the process of communication". The main focus of the model is broken down by each element of communication: "' who' refers to the communicator who formulates the message;' what' is the content of message;' channel' indicates the medium of transmission;' whom' describes either an individual recipient or the audience of mass communication;' effect' is the outcome of the message ..." The movement of the message travels from the communicator to the audience . Although this model represents a one - way flow of communication, the "effect" also refers to feedback in public relations . The model can be used in pedagogical settings to teach students major elements of a communication process and as a starting point for developing hypotheses . </P> <P> Lasswell stated that the "Who" referred to "control analysis", the "Says What" referred to "content analysis", the "In Which Channel" referred to "media analysis", the "To Whom" referred to "audience analysis", and the "With What Effect" referred to "effect analysis". </P> <Table> <Tr> <Th> Question </Th> <Th> Element </Th> <Th> Analysis </Th> </Tr> <Tr> <Td> Who? </Td> <Td> Communicator </Td> <Td> Control Analysis </Td> </Tr> <Tr> <Td> Says What? </Td> <Td> Message </Td> <Td> Content Analysis </Td> </Tr> <Tr> <Td> In Which Channel? </Td> <Td> Medium </Td> <Td> Media Analysis </Td> </Tr> <Tr> <Td> To Whom? </Td> <Td> Audience </Td> <Td> Audience Analysis </Td> </Tr> <Tr> <Td> With What Effect? </Td> <Td> Effect </Td> <Td> Effects Analysis </Td> </Tr> </Table> <Tr> <Th> Question </Th> <Th> Element </Th> <Th> Analysis </Th> </Tr>
