Mechanistic communication structures are characterised by a traditional top down hierarchy and are traditionally the domain of “large-scale, and low-complexity structures,” (Grunig 1992, p.403) Mechanistic communication usually occurs vertically throughout the hierarchy – Top management to upper management, upper management to middle management, middle management to supervisory, supervisory to entry level personnel (and vice-versa). When mechanistic structures are viewed outside a business environment we can see them in force throughout our levels of government, in private enterprise, in schools and universities.
Organic communication is characterised by a non-linear communication structures within an organisation, and are frequently “Small in scale but high in complexity,” (Grunig 1992, p.403). Communication usually occurs in a lateral method of “consultation rather than vertical commands” (Burns & Stalker 1961, p.121), where “members can speak freely to anyone in the group,” (Bell & Smith 2010, p.33). When looking for organic communication structures outside a business environment, we will see them in places such as public forums, brainstorming sessions, and response teams which are required to work autonomously (medical, police etc).
In a traditional mechanistic (also referred to as bureaucratic) structure, communication is centralised, meaning that it there is a clear
