Methods of production

Welcome to Methods of Production!

Ever wondered why a custom-made piece of jewelry costs so much more than a plastic ring from a supermarket? Or how factories manage to produce thousands of cans of soda every single minute? It all comes down to the method of production a business chooses.

In this chapter, we are going to explore the different ways businesses organize their work to turn raw materials into finished products. Don't worry if some of these terms seem a bit technical at first—we'll break them down using examples you see every day!

1. The Four Main Methods of Production

Businesses generally choose one of four ways to make their products. Think of these as different "recipes" for organizing a factory.

A. Job Production

Job production involves making "one-off" or unique items specifically to meet a customer’s exact requirements. Each "job" is finished before the next one starts.

Example: A tailor making a bespoke suit, a construction firm building a specific bridge, or a baker creating a unique wedding cake.

• Pros: Very high quality; high employee motivation (they see the whole project through); can charge a premium price.
• Cons: High cost per unit; slow production; requires highly skilled (and expensive) labor.

B. Batch Production

Batch production is when a group (or "batch") of identical products are made together. Once that batch is finished, the machines are cleaned or adjusted, and a different batch is started.

Example: A bakery making 50 loaves of sourdough bread, then cleaning the ovens to make 50 croissants.

• Pros: More flexible than flow production; lower costs than job production; allows for some variety.
• Cons: Costs of "downtime" (when machines are stopped to change between batches); higher storage costs for finished goods.

C. Flow Production

Flow production (also called mass production) involves a continuous, 24/7 movement of items along a production line. Every item is identical.

Example: A Coca-Cola bottling plant or a factory producing thousands of identical pens.

• Pros: Massive economies of scale (low cost per item); very fast; can use a lot of automation/machinery.
• Cons: Massive setup costs (expensive factories); very boring for workers; if one machine breaks, the whole line stops.

D. Cell Production

Cell production is a modern twist where the production line is split into several units or "cells." Each cell is a team of workers who are responsible for a complete part of the production process.

Example: In a car factory, one "cell" might be responsible for the entire dashboard assembly, while another handles the engine.

• Pros: Better communication; improved quality (teams take "ownership" of their work); higher motivation.
• Cons: May require more factory space; requires workers to be "multi-skilled."

Job, Batch, Flow, Cell.

Key Takeaway: Job is for unique items, Batch is for groups, Flow is for mass identical items, and Cell is for team-based production.

2. Choosing the Right Method

A business doesn't just pick a method at random. They have to evaluate several factors. Don't worry if this seems like a lot to consider—just think about what a business owner would worry about!

Reasons for the Choice:

• The Product: Is it unique (Job) or standardized (Flow)?
• Size of the Market: If millions of people want the product, Flow is best. If only ten people want it, Job is better.
• Finance: Does the business have the money to buy massive robots for a Flow line?
• Technology: Is the right machinery available?

Impact on Stakeholders:

• Customers: Flow production usually means lower prices, but Job production means getting exactly what you want.
• Employees: Flow production can be very repetitive and boring (leading to low motivation), whereas Job or Cell production gives workers more variety.
• Owners/Shareholders: Flow production usually leads to the highest profits if they can sell in large quantities.

Common Mistake to Avoid: Many students think Batch and Flow are the same. Remember: Batch has a "stop" or a "gap" between different groups of products. Flow never stops—it is a continuous stream!

Key Takeaway: The choice of production method depends on the size of the market, the nature of the product, and the money available. Each method affects stakeholders (like workers and customers) differently.

3. Specialisation and Division of Labour

This sounds like a complex topic, but you actually see it every time you go to a fast-food restaurant!

What is it?

• Division of Labour: This is when a production process is broken down into small, specific tasks.
• Specialisation: This is when a worker or a machine focuses on just one of those tasks to become an expert at it.

The Pizza Analogy:
Imagine one person making a pizza alone. They roll the dough, add sauce, add cheese, add toppings, and put it in the oven. It takes a long time.
Now imagine Division of Labour:
Person A: Only rolls dough.
Person B: Only adds sauce.
Person C: Only adds cheese.
Because they specialise, they become incredibly fast at their one specific job, and the pizza is made much quicker!

Why do businesses use it?

• Increased Efficiency: Work is done much faster.
• Skill Improvement: "Practice makes perfect"—workers become experts at their specific task.
• Saves Time: Workers don't waste time moving between different tools or stations.
• Easier to Automate: It’s easier to build a machine that does one simple thing (like putting a lid on a bottle) than a machine that does everything.

The Downsides (The "Watch-Outs"):

• Boredom: Doing the same thing every 10 seconds is mentally exhausting. This is often called alienation.
• Risk of Errors: If a worker gets bored, they might make mistakes.
• Interdependency: If the "dough roller" gets sick and stays home, the whole pizza line has to stop because the "sauce adder" has nothing to work on.

Did you know? Adam Smith, the "father of economics," famously wrote about a pin factory where 10 workers using division of labour could make 48,000 pins a day, whereas one person doing everything might struggle to make even one!

Key Takeaway: Specialisation and division of labour make production much faster and cheaper, but they can lead to unhappy, bored workers and make the business vulnerable if one part of the chain fails.

Chapter Summary

• Job Production: Unique, high quality, expensive.
• Batch Production: Groups of similar items, flexible.
• Flow Production: Continuous, identical items, low cost per unit.
• Cell Production: Team-based, improves motivation and quality.
• Division of Labour: Breaking a job into small parts to increase speed and skill.

Great job! You’ve mastered the basics of how businesses choose to make their goods. Keep these analogies in mind, and you'll do great in your revision!
