2.4.1 - Production, Productivity and Efficiency

Job and batch production

The first production decision is usually about volume and variety. If customers want something unique, the business needs a method that allows flexibility and skill. If customers want several similar items, the business can begin to standardise the process and reduce cost per unit.

Job production suits one-off or highly customised output. A wedding cake designer, a bespoke furniture maker, or a firm designing a specialist machine for one client is unlikely to use a continuous line. Because the work is tailored, skilled labour is usually needed and production takes longer. That means unit costs tend to be higher, so firms often need to charge premium prices to protect profit.

Batch production is used when a business wants some variety but also wants more efficiency than job production can offer. A bakery might make one batch of white rolls, then reset equipment and make a batch of seeded rolls. This gives more flexibility than flow production, but the switching time between batches can reduce output and raise costs if changeovers are frequent.

The key difference is that job production prioritises customisation, while batch production begins to gain efficiency through repetition. As firms move from one-off work to repeated groups of similar items, standardisation increases and the average cost per unit can start to fall.

Flow and cell production

When demand is large and products are standardised, businesses often move further towards continuous systems. At that point, the aim is usually to keep output moving smoothly, reduce delays, and spread fixed costs over many units.

Flow production is most suited to high-volume, standardised output. Because each stage follows on continuously from the previous one, firms can produce quickly and at a lower average cost. This often goes with heavy use of machinery, so flow production is commonly capital-intensive. However, if one stage breaks down, the whole line may be disrupted, and the system is usually much less flexible than job or batch production.

Cell production tries to combine some of the efficiency of flow production with more ownership and flexibility. A cell is a small self-contained unit, often responsible for a family of related products. Because workers are organised into teams and handle a meaningful section of the process, communication and problem-solving can improve. This can reduce delays and waste without forcing the whole factory into one rigid continuous line.

The easiest way to compare the four methods is to match each one to the type of output required.

Managers therefore choose a method by balancing variety, output volume, speed, and cost. A business making specialist products may accept higher unit costs because customers value tailored output. A business selling identical products in large volumes is more likely to prioritise speed and standardisation.

Productivity and competitiveness

Once a business has chosen a production method, managers still need to ask how much output is being produced from the resources being used. That is what productivity measures. In exams, it is important not to confuse productivity with total output. A business can produce more simply by hiring more labour, but productivity rises only if output per unit of input increases over a given period of time.

For labour productivity, the input is usually the number of workers or labour hours. For capital productivity, the input is the machine or equipment being used. The core idea is the same in both cases: if more usable output is produced from the same input in the same time, productivity has improved.

Several factors influence productivity. Better training can reduce mistakes and help workers complete tasks more quickly. Higher motivation can raise effort and cut absenteeism. Greater specialisation and division of labour can speed up repeated tasks. Investment in reliable machinery, plus effective maintenance, can also increase output by reducing downtime. In each case, the chain is similar: better people or processes lead to more output from the same resources, which improves productivity.

The link with competitiveness is direct. If productivity rises, the cost per unit can fall because each worker or machine is generating more output in the same time period. Lower unit costs may allow a business to reduce price, and that can make it more attractive than rivals. Alternatively, the firm may keep price the same and earn a higher margin, which gives it more money to invest in quality, promotion, or new technology. Either way, higher productivity can strengthen competitiveness.
