Organisational structures

🎬 The doodle video for this lesson is coming soon. Subscribe on YouTube to see it first.

An organisational structure shows who is in charge of whom and how decisions flow through a business.

Key terms

Hierarchy: the levels of management.
Chain of command: the line of authority from the top to the bottom.
Span of control: the number of people who report directly to one manager.
Delegation: passing authority to do a task down to someone lower in the hierarchy.

Tall and flat

Centralised and decentralised

Centralised: important decisions are made at the top (head office). Consistent, but slow and less responsive to local needs.
Decentralised: decisions are delegated to branches or lower levels. Faster and suits local needs, and motivates staff, but less consistent.
Worked example

A manager has 12 staff reporting directly to her. What is her span of control?

  1. Span of control = number of direct reports.

Answer: 12

Key idea

Hierarchical structures have many levels, narrow spans and long chains; flat structures have few levels and wide spans. Centralised: decisions at the top. Decentralised: decisions delegated down.
