Welcome to Operations Management: Getting the Most Out of Your Business!
Hello! Today we are diving into a very practical part of Business: Capacity Utilisation and Outsourcing. Essentially, we are looking at two big questions: "How much can our business actually produce?" and "Should we do the work ourselves or pay someone else to do it?"
Don't worry if these terms sound a bit "corporate" at first. By the end of these notes, you'll see they are just common sense applied to running a successful company. Let’s get started!
1. What is Capacity Utilisation?
Before we measure it, we need to know what Capacity is. Think of it as the "limit." If you have a cinema with 100 seats, your maximum capacity is 100 people. If only 60 people show up, you aren't using all your capacity.
Capacity Utilisation is simply a way of measuring what percentage of your total possible output you are actually using.
How to Calculate It
To find the percentage, we use this simple formula:
\( \text{Capacity Utilisation} = \left( \frac{\text{Actual Level of Output}}{\text{Maximum Possible Output}} \right) \times 100 \)
Example Time!
Imagine a bakery that has the ovens and staff to bake 500 loaves of bread a day (Maximum Capacity). Today, they only baked 400 loaves (Actual Output).
\( \text{Capacity Utilisation} = \left( \frac{400}{500} \right) \times 100 = 80\% \)
Quick Review Box:
- Actual Output: What you are doing right now.
- Maximum Capacity: The most you could possibly do if you worked at full speed.
- The Goal: Usually, businesses want this number to be high, but not always 100%!
Key Takeaway
Capacity utilisation tells a manager how "busy" the business assets (machines and people) are. It is expressed as a percentage.
2. The Impact of Operating "Under" or "Over" Capacity
You might think, "I want to be at 100% all the time!" but in business, being at 100% (Full Capacity) can be just as stressful as being at 20% (Under Capacity).
Operating Under Capacity (Spare Capacity)
This happens when your utilisation is low (e.g., 40% or 50%).
The Downsides:
- Higher Unit Costs: You still have to pay "Fixed Costs" like rent and insurance. If you only make a few items, each item has to "carry" more of that rent cost, making it more expensive to produce.
- Boredom: Staff might feel demotivated because they have nothing to do.
The Upsides:
- Flexibility: If a new customer calls with a huge "rush order," you have the space and time to say "Yes!"
Operating at Full Capacity (100%)
This is when you are working at your absolute limit.
The Downsides:
- No Room for Error: If one machine breaks down, the whole production line stops.
- Stress: Staff can get tired and overworked, leading to mistakes or accidents.
- Turning Customers Away: You can't take on any new orders, so customers might go to your competitors.
The Upsides:
- Lower Unit Costs: Your fixed costs are spread over the maximum number of items, making each one cheaper to make (this is called Economies of Scale).
Did you know? Most businesses aim for an "ideal" capacity of about 90%. This is high enough to keep costs low but leaves a little "breathing room" for repairs or unexpected orders!
Key Takeaway
Under-capacity leads to high average costs and wasted resources. Full capacity leads to stress and a lack of flexibility. Balance is key!
3. How to Improve Capacity Utilisation
If a manager realizes their capacity utilisation is too low, they need to fix it. There are two main ways to do this:
Method A: Increase Demand
Try to get more customers so you have more work to do!
1. Marketing: Run a sale or an advertising campaign.
2. New Markets: Try selling your product in a different country or to a different group of people.
Method B: Reduce Capacity (Rationalisation)
If you can't get more customers, make the business smaller so you aren't wasting space.
1. Selling Assets: Sell off machines you don't use.
2. Moving: Move to a smaller factory or office.
3. Layoffs: Reduce the number of staff (though this is a very difficult decision).
Common Mistake to Avoid: Students often think "Improving Capacity Utilisation" only means making more products. Remember, you can also "improve" it by cutting your maximum capacity (making the "denominator" in our formula smaller).
Key Takeaway
To fix low utilisation, you must either sell more or shrink the business.
4. Outsourcing
Sometimes, a business is at full capacity and can't make any more. Or, maybe they aren't very good at making a specific part of their product. In these cases, they use Outsourcing.
Outsourcing is when a business hires another outside business to perform a task or produce a component instead of doing it "in-house."
Real-World Analogy
Think of a busy restaurant. They are great at cooking food, but they might outsource their delivery to a company like UberEats or Deliveroo. This allows the restaurant to focus on cooking while someone else handles the driving.
The Impact of Outsourcing on a Business
The Pros (Why do it?):
- Focus: The business can focus on what it does best (its "core competencies").
- Cost Savings: Sometimes another company can do the job cheaper because they are specialists.
- Flexibility: If demand drops, you can just stop the contract with the outside company rather than having to fire your own workers.
The Cons (The Risks):
- Quality Control: You aren't watching the work being done. If the outsider does a bad job, it's your brand that looks bad.
- Reliability: If the outside company goes on strike or runs out of parts, your production stops too.
- Loss of Secrets: You might have to share your designs or recipes with the outside company, which is risky!
Memory Aid: The "C-Q-R" Rule for Outsourcing When evaluating outsourcing, always think about Cost, Quality, and Reliability.
Key Takeaway
Outsourcing helps a business stay lean and flexible, but it requires giving up some control over the production process.
Final Quick Check!
