Job, batch and flow production in IGCSE Business: what you need to know
This free game is part of our Pearson Edexcel IGCSE Business (4BS1) course for exams in EXAM YEARS 2026-2029.
The secondary sector and methods of production
The secondary sector is made up of businesses that turn raw materials into finished goods: manufacturing, construction and production. For IGCSE Business you need to know the three main methods of production: job, batch and flow. Each suits a different kind of product and order size.
In The Production Line you run a 3D factory with a job area, a batch area and a flow line. Orders arrive and you decide how to make each one. A good choice makes profit, a poor one loses it. Then the conveyor belt round tests the facts at speed.
Job production
Job production means making one-off, unique items to the customer's exact requirements. Examples include handmade furniture, engagement rings and Rolls-Royce cars. Each Rolls-Royce takes about six months, so the company makes only a few thousand a year.
- Advantages: exactly what the customer wants, high quality, a premium price and skilled, motivated workers.
- Disadvantages: a high cost per unit, slow to produce and it needs expensive skilled labour.
Batch production
Batch production means making a group of identical products, then resetting the machines to make a different group. A bakery might make 50 white loaves, then 50 brown. Clothing ranges and school uniforms are also made in batches.
- Advantages: some variety at a lower cost than job production, machines can be reused for several products, and output can match demand for each type.
- Disadvantages: downtime while machines are reset, stock of each batch must be stored, and there is less customisation than job production.
Flow production
Flow production is continuous mass production of identical items moving along a production line, often 24 hours a day. Car assembly lines, canned drinks and games consoles are made this way. Nissan's plant in Sunderland is one of the biggest car factories in Europe.
- Advantages: the lowest cost per unit thanks to economies of scale, very high output and consistent quality that is easy to automate.
- Disadvantages: a huge setup cost for the machinery, repetitive work that can demotivate staff, and one breakdown can stop the whole line.
Exam tips
- Use the quick rule: one special item = job, a group, then switch = batch, millions the same = flow.
- Look at the quantity and how much customisation the customer wants before choosing a method.
- For job production, say it gives high quality and happy customers but a high cost per item. For batch, always mention downtime.
Frequently asked questions
What is the difference between job, batch and flow production?
Job production makes one-off items to order, batch production makes groups of identical products before switching to a new group, and flow production makes identical items continuously on a production line.
Which method of production has the lowest cost per unit?
Flow production, because making huge numbers of identical items gives economies of scale. However, it has the highest setup cost for machinery.
What is downtime in batch production?
Downtime is the time lost when machines are stopped and reset to switch from one batch to the next. No products are made during this time, which raises costs.
Why might workers be demotivated in flow production?
Workers often do the same small task all day, which is repetitive and boring. This can lower motivation and increase staff turnover.
Is The Production Line free?
Yes. The game is free to play in your browser with no sign-up. It covers methods of production from the Pearson Edexcel IGCSE Business (4BS1) specification.
