Organisational structure

Organisational structure is the way a company arranges its people, teams and reporting lines so work can be coordinated effectively.

What is organisational structure?

Organisational structure defines how a business is organised — who reports to whom, how teams are grouped and how decisions flow through the company. A clear structure helps people understand their roles, responsibilities and relationships with others. It also shapes how information moves, how quickly decisions are made and how flexible the organisation can be.

Structures vary widely, from traditional hierarchies to flatter, more collaborative models, and often evolve as a business grows or its priorities change.
