Welcome to Organisational Design!
Ever wondered why some businesses feel like a giant, slow-moving machine while others feel like a fast-paced, "let's just do it" team? It usually comes down to organisational design. This is essentially the blueprint or "skeleton" of a business. It decides who is in charge, how messages travel, and who makes the big decisions. Since we are in the "Managing People" section, we are looking at how these structures affect the way employees work, how happy they are, and how much they get done.
Don’t worry if this seems a bit dry at first—once you see how it works in real life (like at your school or a shop you visit), it becomes much easier to understand!
1. The Building Blocks of Structure
Before we look at the different types of business "shapes," we need to understand the four key terms used to describe them. Think of these as the DNA of a company.
A. Hierarchy
Hierarchy refers to the number of layers of management in a business. If a business has a "long" hierarchy, there are many levels between the shop floor worker and the CEO at the top.
Example: In a large army, you have Private, Corporal, Sergeant, Lieutenant, Captain... all the way up to General. That is a tall hierarchy!
B. Chain of Command
The chain of command is the path through which orders are passed down the hierarchy. It shows who reports to whom. A clear chain of command is vital so that everyone knows who their boss is and who they should take instructions from.
C. Span of Control
The span of control is the number of subordinates (employees) that a manager is directly responsible for.
• A narrow span of control means a manager looks after just a few people (e.g., 2 or 3).
• A wide span of control means a manager looks after many people (e.g., 15 or 20).
D. Centralised and Decentralised
This is all about where the decisions are made:
• Centralised: All the major decisions are made at the very top (Head Office). Local managers have very little say.
• Decentralised: Decision-making power is pushed down the hierarchy. Local or department managers are allowed to make their own choices.
Quick Review: The "Pizza Shop" Analogy
Imagine a pizza chain:
• If it’s centralised, the Head Office decides the price of every pizza in every town.
• If it’s decentralised, the manager of the Manchester branch can decide to have a "Rainy Day Special" discount without asking permission first.
Key Takeaway: Hierarchy is about layers; Chain of Command is about the flow of orders; Span of Control is about how many people you manage; Centralisation is about where the power sits.
2. Types of Organisational Structure
Businesses usually fall into one of three main "shapes." Let’s break them down.
The Tall Structure
A tall structure has many layers of hierarchy and usually narrow spans of control.
Pros:
• Clear paths for promotion (you can move up the ladder many times).
• Managers have more time for each employee because they only look after a few.
Cons:
• Communication is slow because messages have to pass through so many levels.
• It can be expensive because you have to pay for lots of managers.
The Flat Structure
A flat structure has very few layers and wide spans of control.
Pros:
• Communication is much faster (the boss is "closer" to the workers).
• It’s cheaper because there are fewer middle managers to pay.
Cons:
• Managers can feel overwhelmed because they have too many people to look after.
• Fewer opportunities for employees to get promoted.
The Matrix Structure
A matrix structure is a bit different. Instead of just working for one department, employees are grouped by function (e.g., Marketing) and by project (e.g., Launching a New App).
Example: You might report to your usual Marketing Manager, but also to a Project Leader for the "New App" team.
Don't worry if this seems tricky! Just remember: Matrix = Working across teams. It’s great for creativity but can be confusing because you have two bosses!
Did you know?
Many modern tech companies like Google or Spotify use flat or matrix structures to keep things moving fast and to encourage everyone to share ideas!
Key Takeaway: Tall structures are traditional and controlled; Flat structures are fast and lean; Matrix structures are flexible and project-based.
3. Impact on Efficiency and Motivation
Why does all of this matter? Because the way a business is designed changes how people feel (motivation) and how well they work (efficiency).
Impact on Efficiency
• Speed: Flat structures are usually more efficient at making quick changes because they don't have to wait for "permission from the top" through ten layers of management.
• Cost: Removing layers of management (a process called delayering) can make a business more efficient by cutting wage costs.
Impact on Motivation
• Empowerment: Wide spans of control and decentralisation often motivate staff. Why? Because managers don't have time to "micro-manage" them. Employees feel trusted to make their own decisions.
• Promotion: Tall structures can motivate people who want to "climb the ladder."
• Stress: If a span of control is too wide, employees might feel unsupported, which can lower motivation.
Common Mistake to Avoid
Students often think "Tall = Bad" and "Flat = Good." This isn't always true! A tall structure provides order and clear supervision, which is very important in industries like nuclear power or medicine where mistakes are dangerous.
Memory Aid: The "Rubber Band" Trick
Think of the span of control like a rubber band. If it's too narrow, it's not doing much work (the manager is bored). If it's stretched too wide, it might snap (the manager is stressed). A business tries to find the "perfect stretch" for its people.
Key Takeaway: Structure isn't just a diagram; it affects how fast a business moves and whether the employees feel trusted or ignored.

Great job! You’ve covered the essentials of Organisational Design. Remember, in the exam, always think about how these structures affect the specific business in the case study!
