Methods of production (job, batch and flow production) and the difference between labour-intensive and capital-intensive production, with the advantages and disadvantages of each.

What this key area is asking

Methods of production are the ways a firm actually makes its products. The SQA wants you to distinguish job, batch and flow production, explain the difference between labour-intensive and capital-intensive production, and judge which suits a given product. Higher rewards you for weighing the advantages and disadvantages, especially the trade-off between cost and flexibility/customisation.

Job, batch and flow production

Job production

Job production makes a single, unique product at a time, exactly to the customer's specification. Examples are a tailor-made suit, a wedding cake, a bridge or a ship.

• Advantages: high quality and craftsmanship; fully customised to the customer; can charge a premium price; motivating, skilled work.
• Disadvantages: slow and labour-intensive; expensive per unit; needs skilled (costly) workers; hard to gain economies of scale.

Batch production

Batch production makes a batch (group) of identical items, then changes the set-up to make a batch of something different. A bakery makes a batch of white loaves, then a batch of brown, then rolls.

• Advantages: allows variety within the same equipment; some economies of scale; more flexible than flow production.
• Disadvantages: downtime when switching between batches (cleaning, resetting machines); stock of part-finished goods builds up; less efficient than flow.

Flow production

Flow production makes identical products continuously on a production line, such as cars, bottled drinks or chocolate bars.

• Advantages: very high output; low unit costs from economies of scale; consistent standard product; can run 24 hours a day.
• Disadvantages: inflexible (hard to vary the product); expensive to set up the line; a breakdown halts the whole line; repetitive, less motivating work.

Labour-intensive and capital-intensive production

This is a separate distinction about the main input a firm relies on.

• Labour-intensive is flexible and suits skilled, customised or small-scale work, but labour is costly, output is slower and quality can vary between workers.
• Capital-intensive gives fast, consistent, high-volume output at low unit cost, but needs heavy investment in machinery, is less flexible, and may reduce jobs.

Examples in context

Example 1. A bakery using batch production. A bakery makes a batch of white loaves, cleans and resets the equipment, then makes a batch of wholemeal, then a batch of rolls. This gives a variety of products from the same ovens and some economies of scale, but there is downtime between batches for cleaning and changeover, the classic trade-off of batch production against the continuous efficiency of flow.

Example 2. A car plant using capital-intensive flow production. A car factory uses a flow production line that is highly capital-intensive, with robots welding and assembling identical cars continuously. This gives huge output at low unit cost and consistent quality, but the line is expensive to set up and inflexible, and a single breakdown can stop the whole line, showing why flow and capital intensity suit only high-volume, standardised products.

Try this

Q1. Distinguish between job and flow production. [2 marks]

• Cue. Job production makes one unique product at a time to a customer's specification (a ship, a wedding cake), high quality but slow and costly; flow production makes identical products continuously on a line (cars, drinks), high output at low unit cost but inflexible.

Q2. Explain two advantages of capital-intensive production. [4 marks]

• Cue. It gives fast, high-volume output, so the firm can meet large demand; it produces a consistent, standard quality with fewer human errors; and the low unit cost from economies of scale makes products cheaper to produce, improving competitiveness (any two, developed).
