Quick answer

Production is how a business turns inputs into the goods or services it sells, and there are three main methods. Job production makes one unique item at a time, made to a customer's specific order, such as a wedding dress, a portrait or a custom kitchen; it gives high quality and customisation and motivates skilled workers, but it is slow and expensive per unit. Batch production makes a group (a batch) of identical items together before switching to a different batch, such as a bakery making 200 loaves then 200 rolls; it offers some variety and is more efficient than job production, but time and money are lost when switching between batches and stock must be stored. Flow production makes large quantities of an identical product continuously on a production line, such as bottled drinks or cars; it is fast and gives a very low cost per unit through economies of scale, but it is inflexible, the products are all the same, and the machinery is expensive to set up. Productivity is the amount of output produced per worker or per hour, and improving it (through training, better machinery or motivation) lowers the cost of each unit, making the business more competitive. A business chooses its method based on the type of product, the size of demand, the level of customisation needed and the money available.

What this dot point is asking

WJEC wants you to know the three main methods of production: job, batch and flow. You need the advantages and disadvantages of each, the meaning of productivity and efficiency, and the factors that affect which method a business chooses. Operations is the function that actually makes the goods or delivers the service, so the production method shapes cost, quality and how much the business can make.

Choosing a method

A business chooses its production method based on the type of product (unique or standard), the size of demand (small orders or mass market), the level of customisation the customer wants, and the money available to invest in machinery.

Why this matters

Production is where adding value happens, so it links to cost and profit (the method decides the cost per unit), to marketing (a custom job product supports a premium price, a flow product suits a mass market), and to growth (flow production delivers the economies of scale that come with size). Productivity reappears in finance and human resources. Exam questions usually ask you to recommend a method for a given product, where the type of product, demand and cost are the deciding points.

Calculate and use productivity

A workshop has 5 workers who together make 400 chairs in a week. After training, the same 5 workers make 500 chairs a week.

step Find productivity per worker before training

\text{Productivity} = \frac{\text{output}}{\text{number of workers}} = \frac{400}{5} = 80 \text{ chairs per worker}.

step Find productivity per worker after training

\text{Productivity} = \frac{500}{5} = 100 \text{ chairs per worker}.

step Interpret the result

Productivity has risen from 80 to 100 chairs per worker, a 25 percent increase, from the same five workers. Because the workshop now makes more chairs without hiring extra staff, the labour cost spread over each chair falls, so the cost per chair drops. That lets the business lower its price to win customers or keep more profit, which is exactly why firms invest in training to raise productivity.

Q1. State one advantage and one disadvantage of flow production. [2 marks]

Cue. Advantage: very low cost per unit (economies of scale). Disadvantage: inflexible, with high set-up costs.

Q2. A team of 4 workers makes 240 units in a day. Calculate the productivity per worker. [1 mark]

Cue. $240 \div 4 = 60$ units per worker.

WJEC (Unit 1)3 marksExplain the difference between job production and flow production.

Show worked answer →

A 3-mark AO1 explain question. Reward a clear contrast with development.

Job production makes one unique item at a time, made to a customer's specific order, such as a wedding dress or a custom kitchen. It allows high quality and customisation but is slow and expensive per unit.

Flow production makes large quantities of an identical product continuously on a production line, such as bottled drinks or cars. It is fast and gives a low cost per unit through economies of scale, but it is inflexible and the products are all the same. Markers reward the definition of each plus the key contrast of customisation versus volume.

WJEC (Unit 1)6 marksAnalyse the benefits to a business of improving its productivity.

Show worked answer →

A 6-mark AO1, AO2 and AO3 question. Reward developed benefits.

Benefit one: higher productivity means more output from the same resources, so the cost of making each unit falls, which lets the business lower its prices to compete or earn more profit on each sale.

Benefit two: producing more efficiently helps the business meet demand and deliver on time, improving customer satisfaction and its reputation.

Chain and judgement: improving productivity cuts unit costs and raises competitiveness, though it may need investment in training or machinery, so the benefit is greatest when the savings outweigh that cost. Markers reward developed benefits plus a balanced comment.
