Welcome to Capacity Utilisation!
In this chapter, we are diving into a crucial part of Resource Management. Think of Capacity Utilisation as a measure of how "busy" a business is compared to how busy it could be. Whether you are running a massive car factory or a small local cafe, understanding this concept helps you figure out if you are getting the most out of your expensive equipment and staff.
Don't worry if the numbers seem a bit scary at first—we’ll break them down step-by-step!
1. What is Capacity Utilisation?
At its simplest, Capacity is the maximum amount a business can produce in a set period using its current resources (like machinery, space, and people).
Capacity Utilisation is the percentage of that maximum capacity that is actually being used. It tells us how much "slack" or "waste" there is in the business.
The Formula
To find the percentage, we use this simple calculation:
\( \text{Capacity Utilisation} = \frac{\text{Current Output}}{\text{Maximum Possible Output}} \times 100 \)
Example: Imagine a cinema with 200 seats. On a Tuesday night, only 50 people buy tickets to see a movie.
\( \text{Utilisation} = \frac{50}{200} \times 100 = 25\% \)
The cinema is only 25% full. They have a lot of empty seats!
Quick Review: The Prerequisites
Before we move on, remember that Output is just the number of goods or services actually made. Resources are the things used to make them (like ovens in a bakery).
Key Takeaway: Capacity utilisation measures how much of a business's total potential is actually being turned into products or services.
2. Under-Utilisation: When Things are Too Quiet
Under-utilisation (also called "spare capacity") happens when a business is operating significantly below its maximum level (e.g., 40% or 50% utilisation).
Why is this a problem?
The biggest issue here is Average Unit Costs. Most businesses have Fixed Costs (like rent or insurance) that stay the same no matter how much they produce. If you produce very little, those big costs are spread over fewer items, making each item more expensive to make!
The "Empty Bus" Analogy: Think of a bus company. It costs the same amount of fuel and driver wages to send a bus across town whether it has 1 person on it or 50. If only 1 person is on the bus, the "cost per passenger" is huge. If the bus is full, the "cost per passenger" is much lower.
The Pros and Cons of Under-Utilisation
The Downsides:
• Higher average unit costs (lower profit margins).
• It can look bad to customers (an empty restaurant looks unpopular).
• Staff might get bored or unmotivated.
The Surprising Upsides:
• Flexibility: If a sudden big order comes in, the business can handle it easily.
• Maintenance: There is plenty of time to fix machines without stopping production.
• Less stress for workers.
Key Takeaway: Low utilisation usually means higher costs per item, which can hurt profits. However, it gives the business room to grow quickly if demand rises.
3. Over-Utilisation: When Things are Too Busy
You might think 100% utilisation is the goal, but running at Full Capacity (or over-utilisation) creates its own set of headaches.
The Stress of 100%
When a business is "flat out," every machine is running and every worker is busy every second of the day.
The "Stressed Chef" Analogy: Imagine a kitchen where the chef is cooking on every single burner and has a queue of 50 orders. If one pot boils over or one plate breaks, the whole system crashes because there is no "breathing room."
The Pros and Cons of Over-Utilisation
The Upsides:
• Lowest average unit costs: Fixed costs are spread over the maximum number of items.
• High morale: Staff feel the business is successful and their jobs are secure.
The Downsides:
• Quality issues: Mistakes happen when people are rushed.
• No time for maintenance: If a machine breaks, production stops completely because there is no backup.
• Stress: Staff may suffer from burnout or take more sick days.
• Turning away customers: If you are at 100%, you have to say "no" to new orders.
Did you know? Most businesses aim for an Optimal Capacity of about 90%. This is high enough to keep costs low but leaves a 10% "buffer" for emergencies or maintenance.
Key Takeaway: 100% utilisation is great for lowering costs but dangerous for quality, machine health, and staff well-being.
4. Ways of Improving Capacity Utilisation
If a business identifies that its utilisation is too low or too high, it needs to take action. This is a common exam topic!
If Utilisation is TOO LOW (Spare Capacity):
The goal is to either increase demand or reduce capacity.
1. Increase Demand: Use marketing, price cuts, or promotions to get more customers (e.g., "Happy Hour" at a bar during quiet times).
2. Subcontracting/Outsourcing: A factory could offer to make products for other companies to keep its machines running.
3. Rationalisation: This is a fancy word for "downsizing." The business might sell off unused machinery, close a quiet branch, or move to a smaller building to reduce its maximum capacity.
If Utilisation is TOO HIGH (Over-Utilisation):
The goal is to increase capacity or reduce the pressure.
1. Expand: Buy more machinery or hire more staff (this is expensive and takes time).
2. Outsourcing: Pay another business to do some of the work for you so you can meet demand.
3. Increase Prices: This might lower demand slightly, but it increases profit on the items you do sell and reduces the stress on the factory.
Common Mistake to Avoid: Don't confuse Capacity with Demand. Capacity is what you can do; Demand is what customers want. Utilisation is the link between them.
Key Takeaway: To fix low utilisation, you must find more customers or get rid of resources. To fix high utilisation, you must grow the business or get outside help.
Summary: The "Quick Study" Box
• High Utilisation (near 90-100%): Low unit costs, high efficiency, but high stress and no room for error.
• Low Utilisation (below 50-60%): High unit costs, inefficient, but very flexible and easy to maintain.
• The Formula: (Current Output ÷ Max Output) x 100.
• Memory Aid: Remember "CUCOMO" (Capacity Utilisation = Current Output / Max Output).
