Organizational communication is defined as the sending and receiving of messages among interrelated individuals within a specified environment or setting to achieve individual and common organizational goals. Pioneers like Claude Shannon and Warren Weaver (1949) initially established the mathematical model of communication, which was later expanded by David Berlo (1960) into the SMCR Model (Source, Message, Channel, Receiver), emphasizing psychological filters such as attitudes, knowledge, and socio-cultural systems.
- Classical Management Perspective: Fayol’s Administrative Theory emphasizes formal, hierarchical communication channels (gangplank / passerelle principle for horizontal communication).
- Human Relations Movement: Hawthorne Studies led by Elton Mayo (1930s) highlighted the critical role of the informal communication network, commonly known as the 'grapevine', in determining employee morale and productivity.
- Systems Theory Approach: Katz and Kahn (1966) conceptualized organizations as open social systems that depend on dynamic information exchange with their external and internal environments to maintain negative entropy.
