How to approach

Begin by defining organisation structure using standard administrative theory definitions. Then, systematically distinguish between formal and informal organisations on parameters such as origin, authority, communication, and functional impact. Conclude with theoretical synthesis on how both structures complement each other.

Introduction

Organisation structure represents the designated pattern of roles, authority hierarchies, and communication channels consciously designed to coordinate collective human effort toward achieving defined organisational objectives, as conceptualised by administrative theorists like Mooney and Reiley.

Differences Between Formal and Informal Organisation

  • Origin and Creation: Formal organisations are deliberately planned and rationally designed by management to pursue official objectives (exemplified by Max Weber's bureaucratic model). In contrast, informal organisations emerge spontaneously out of personal interactions, common interests, and social affinities among employees (highlighted in Elton Mayo's Hawthorne Studies).
  • Source of Authority: Authority in a formal organisation flows from position, legal rules, and official hierarchy. In an informal organisation, authority or influence stems from personal charisma, social competence, technical knowledge, or mutual acceptance among peers.
  • Communication Channels: Formal structures rely on official, predetermined, and codified channels of communication (scalar chain). Informal structures operate through dynamic, unstructured, and rapidly propagating social networks known as the 'grapevine'.
  • Focus and Objectives: The formal organisation prioritises task performance, predictability, structural efficiency, and accountability. The informal organisation caters to the socio-psychological needs of members, fostering morale, mutual belonging, and psychological tension release.
  • Behavioural Dynamics: Formal organisation behaviour is governed by explicit rules and sanctions. Informal organisations establish unwritten group norms and codes of conduct, which can foster solidarity but may also trigger resistance to organisational change or propagate distorted information.

Conclusion

Far from being mutually exclusive, formal and informal organisations coexist dynamically. As Chester Barnard posited in 'The Functions of the Executive', informal organisations are indispensable for vitalising formal structures and securing voluntary cooperation.

Frequently asked questions

How do informal organisations benefit formal administrative systems?

They provide vital socio-emotional support, facilitate rapid multidirectional communication through the grapevine, and build trust among employees, which Chester Barnard considered essential for executive leadership and organisational vitality.
