4.1.4 Operations Methods: Job, Batch, Flow, Mass Customisation

Differences Between Methods – Advantages And Disadvantages Of Each

Job Production

• Definition: Producing a single product, often customised, from start to finish by one person or a small team.
• Examples: Wedding cakes, tailor-made suits, handmade furniture.
• Advantages:
  • High quality due to skilled craftsmanship.
  • Product differentiation and uniqueness.
  • High customer satisfaction (tailor-made to needs).
  • Motivation for employees due to variety and responsibility.
• Disadvantages:
  • High costs per unit (labour intensive).
  • Time-consuming → low output levels.
  • Requires highly skilled labour.
  • Limited economies of scale.

Batch Production

• Definition: Producing a group of identical products together before moving on to the next batch.
• Examples: Bakery producing batches of bread, clothing factories producing seasonal collections.
• Advantages:
  • Economies of scale compared to job production.
  • Flexibility → different products made in different batches.
  • Lower unit costs than job production.
  • Can meet demand for variety.
• Disadvantages:
  • Time lost switching between batches (downtime).
  • Risk of wastage if demand is lower than expected.
  • Less customer personalisation than job production.
  • Requires careful planning of scheduling.

Flow Production (Continuous Production)

• Definition: Products move continuously through a production line, with each worker/machine performing a specific task.
• Examples: Car assembly lines, bottled water, consumer electronics.
• Advantages:
  • High output, suitable for mass production.
  • Economies of scale achieved.
  • Lower unit costs.
  • Standardised quality with automation.
• Disadvantages:
  • Very high setup and capital costs.
  • Inflexibility – difficult to adjust product types.
  • Work may become repetitive and demotivating for employees.
  • Production line stoppage can cause major delays.

Mass Customisation

• Definition: Combining the efficiency of mass production with the flexibility of customisation.
• Examples: Nike offering customised sneakers, Dell allowing customers to configure laptops.
• Advantages:
  • Meets customer needs while maintaining efficiency.
  • Achieves economies of scale with flexibility.
  • Strengthens brand loyalty and customer satisfaction.
  • Supports differentiation in competitive markets.
• Disadvantages:
  • Requires advanced technology and IT systems.
  • Higher costs than standard mass production.
  • Complexity in managing customised orders at scale.
  • Risk of errors in integrating customisation into production.

The Problems Of Changing From One Method To Another

• From Job To Batch/Flow
  • Requires significant investment in new machinery and equipment.
  • Employees may need retraining, causing resistance and low morale.
  • Loss of craftsmanship focus as standardisation increases.
• From Batch To Flow
  • Transition demands redesigning factory layout for continuous production.
  • High capital expenditure and operational disruption.
  • Risk of overproduction if demand does not justify high output.

• From Flow To Mass Customisation
  • Requires advanced IT integration and flexible machinery.
  • More complex supply chains to handle variety and personalisation.
  • May increase costs while maintaining large-scale efficiency.
• General Problems Of Changing Methods
  • Short-term inefficiencies and reduced productivity.
  • Employee resistance due to new skills, roles, or redundancy threats.
  • Customer disruption if quality or supply is affected during transition.
  • Strategic risk if chosen method does not suit demand levels.

Strategic Importance Of Choosing The Right Method

• Businesses must balance cost, flexibility, quality, and speed when deciding operations methods.
• The right method depends on:
  • Nature of product (unique vs standardised).
  • Customer expectations.
  • Market demand size and variability.
  • Resources and technology available.
• Example:
  • Rolls-Royce uses job production for customised luxury cars.
  • Toyota relies on flow production for efficiency.
  • Nike employs mass customisation to give customers personalised products.
