Formal Organizations vs. Informal Organizations — What's the Difference?

Difference Between Formal Organizations and Informal Organizations


Key Differences

Formal organizations operate on structured and predefined rules and procedures. Informal organizations flourish on interpersonal relationships and personal connections, often emerging naturally among people.
In formal organizations, roles and responsibilities are defined clearly to each member. Informal organizations, on the other hand, do not have such clear-cut roles or hierarchy and function more on a personal and ad-hoc basis.
Formal organizations emphasize a hierarchy, where authority flows from top management down to the employees. Informal organizations involve more horizontal communication and decision-making processes, often without a clear authority structure.
Formal organizations necessitate official communication channels and documentation. Contrastingly, informal organizations allow for casual communication, and decisions can be made without extensive documentation.
Formal organizations often prioritize achieving organizational goals and objectives. Conversely, informal organizations might prioritize group or individual needs and could potentially counteract the formal organizational objectives.
