Welcome to Operational Success!
In this chapter, we are going to explore how businesses actually "do" what they do—but better, faster, and cheaper! We’ll look at how managers make decisions to get the most out of their staff and machines. Whether it's a factory making cars or a café making lattes, efficiency and productivity are the secrets to staying ahead of the competition. Don't worry if some of these terms sound technical; we'll break them down using everyday examples!
1. Understanding Capacity: The "Room to Grow"
Before a business can be efficient, it needs to understand its capacity. Think of capacity as the maximum amount a business can produce in a set time with its current resources (like machines and staff).
Why is Capacity Important?
If a cinema has 100 seats but only 10 people show up, it is under-utilising its capacity. It is wasting money on heating and lighting for an empty room! On the other hand, if 200 people want tickets, the cinema is over-capacity and loses out on potential profit.
How to utilise capacity efficiently:
Businesses try to reach a "sweet spot" (usually around 90%) where they are busy enough to be profitable but still have a little bit of room for extra orders or machine maintenance.
Quick Review:
High capacity utilisation = Lower costs per unit (good!)
Low capacity utilisation = Higher costs per unit (bad!)
2. Efficiency and Labour Productivity
These two terms are often used together, but they mean slightly different things. Efficiency is about doing things right without wasting resources. Labour Productivity is a specific way to measure how much each worker produces.
The Formula for Labour Productivity
To see how hard your team is working, use this formula:
\( \text{Labour Productivity} = \frac{\text{Output per period}}{\text{Number of employees}} \)
Example: If a bakery makes 1,000 loaves of bread a day with 5 bakers, the productivity is 200 loaves per baker.
How to Increase Efficiency and Productivity
- Training: Better-skilled staff work faster and make fewer mistakes.
- Improved Motivation: Happy workers usually work harder (remember Maslow or Herzberg?).
- New Technology: Replacing an old, slow computer with a fast one helps an office worker do more in an hour.
- Better Processes: Changing the layout of a factory so workers don't have to walk as far to get tools.
The Challenges (It’s not always easy!)
Don't worry if this seems tricky at first—even top managers struggle with this! Increasing productivity can be hard because:
1. Quality might drop: If you tell workers to "go faster," they might start making mistakes.
2. Staff stress: Pushing workers too hard can lead to "burnout" and people quitting.
3. Cost: New machines and training are very expensive at the start.
Key Takeaway: Increasing productivity reduces the unit cost (the cost to make one item), which helps a business lower its prices or make more profit.
3. Lean Production: Cutting the "Fat"
Lean production is a Japanese philosophy that focuses on eliminating waste. If an activity doesn't add value for the customer, "Lean" says get rid of it!
Just-in-Time (JIT) vs. Just-in-Case (JIC)
This is a major decision for operations managers. Let’s look at the difference:
Just-in-Time (JIT):
Items are only ordered and produced when they are needed. There is no big warehouse full of spare parts.
Analogy: Like making a sandwich only when a customer orders it so the bread stays fresh and you don't waste ingredients.
Benefit: Saves money on storage and reduces waste.
Difficulty: If the supplier is late, the whole production line stops!
Just-in-Case (JIC):
The business keeps a "buffer" of extra stock just in case there is a sudden surge in demand or a supply problem.
Benefit: You can always meet customer needs, even if things go wrong.
Difficulty: It costs a lot of money to store all that extra "stuff," and it might go out of date.
Did you know? Toyota is famous for pioneering JIT. They realized that keeping piles of car doors in a warehouse was just "money sitting on a shelf" doing nothing!
4. Choosing the Optimal Mix of Resources
Every business must decide: should we use more humans or more machines? This is called the mix of resources.
Labour Intensive
This means the business relies mostly on people.
Examples: Hairdressers, luxury hotels, handmade jewelry.
Pros: Can provide a personal touch and be very flexible.
Cons: People need breaks, get sick, and require wages that go up every year.
Capital Intensive
This means the business relies mostly on machinery and technology.
Examples: Car manufacturing, oil refineries, automated car washes.
Pros: Machines can work 24/7 without getting tired and are very precise.
Cons: Huge "up-front" costs to buy the machines and they can't "think" if a unique problem happens.
How to choose? It depends on the product. You wouldn't want a robot cutting your hair (Labour Intensive), but you probably want a machine to fill 10,000 soda bottles an hour (Capital Intensive)!
5. Using Technology to Improve Efficiency
Technology isn't just about robots; it’s about any tool that makes work better. In the AQA syllabus, you need to know how technology helps operations.
- Robotics: Used in factories for repetitive or dangerous tasks.
- CAD (Computer-Aided Design): Helps architects and engineers design products on a screen rather than drawing by hand.
- Data Tracking: Using software to see exactly where a delivery truck is or how much stock is left on a shelf.
Common Mistake to Avoid: Students often think technology is always better. Remember to mention the drawbacks: technology can be expensive, it can break down, and it might make staff feel insecure about their jobs.
Quick Review: Chapter Checklist
