Diseconomies of Scale Explained – O Level Business Studies (7115 / IGCSE 0450)
What Are Diseconomies of Scale?
Diseconomies of scale occur when a business becomes too large and the average cost per unit starts to increase.
In simple terms, as the business grows beyond a certain size, it may become less efficient.
This leads to higher production costs per unit.
Why Diseconomies of Scale Occur
When businesses become very large, they may face problems such as:
Poor communication
Slow decision making
Management difficulties
Reduced employee motivation
These problems reduce efficiency and increase costs.
Types of Diseconomies of Scale
1. Communication Problems
In very large organizations, communication between departments may become slow and unclear.
Example:
Important information may not reach employees quickly.
2. Management Problems
Large companies often have many management layers, which can make decision-making slower.
Example:
Managers may need approval from several departments before taking action.
3. Low Employee Motivation
In large businesses, employees may feel less valued or less connected to the company.
This can reduce productivity.
4. Coordination Problems
Managing many departments, employees, and locations can be difficult and complex.
This can lead to inefficiencies in production.
Example of Diseconomies of Scale
Imagine a large manufacturing company with thousands of employees.
If communication between departments becomes poor, production may slow down, increasing the cost per unit.
This situation represents diseconomies of scale.
