๐ŸŽจ Job production

Big Idea: Job production means making one unique product at a time, specially designed for each customer. Think custom-made, one-of-a-kind! ๐ŸŽฏ

How does it work?

Each product is made individually, often by skilled workers. It's tailor-made to meet a specific customer's needs.

  • One product made from start to finish before the next begins
  • Highly skilled workers needed
  • Each product can be different
  • Usually small scale
Examples: A wedding cake, a custom-built house, a hand-made suit, a piece of art.

Advantages and disadvantages

  • โœ… High quality and unique products
  • โœ… Workers are motivated (they see the finished result)
  • โœ… Can charge premium prices
  • โœ… Flexible โ€” can meet exact customer needs
  • โŒ Slow and time-consuming
  • โŒ High labour costs (skilled workers are expensive)
  • โŒ Cannot benefit from economies of scale
  • โŒ Hard to produce in large quantities

๐Ÿช Batch production

Big Idea: Batch production means making a group of identical products together before switching to a different product. Like baking 50 chocolate cookies, then switching to 50 vanilla ones! ๐Ÿช

Key features

  • Products are made in groups (batches)
  • Each batch goes through one stage before moving to the next
  • Equipment may need to be reset between batches (changeover time)
  • Allows some variety while still producing in quantity
Examples: A bakery making batches of different breads, a clothing factory producing a batch of size S shirts then size M.

Advantages and disadvantages

  • โœ… Can produce variety (different flavours, sizes, colours)
  • โœ… Cheaper per unit than job production
  • โœ… Flexible โ€” can adjust batch sizes to demand
  • โœ… Can still use some skilled workers
  • โŒ Time lost during changeovers between batches
  • โŒ Work-in-progress stock takes up space and ties up money
  • โŒ Workers may find repetitive tasks boring
  • โŒ Not as cost-efficient as flow production
Exam favourite: If asked to 'state features of batch production', focus on identical products in groups and changeover between batches.

๐Ÿญ Flow (mass) production

Big Idea: Flow production means products move continuously along a production line, one stage after another, non-stop. Think assembly lines and conveyor belts! ๐Ÿ”„

Key features

  • Continuous production โ€” the line rarely stops
  • Standardised (identical) products
  • Heavy use of machinery and automation
  • Very large scale โ€” thousands or millions of units
  • Division of labour โ€” each worker does one specific task
Examples: Car assembly lines, bottling plants, smartphone manufacturing.

Advantages and disadvantages

  • โœ… Very low cost per unit (economies of scale)
  • โœ… Fast and efficient
  • โœ… Consistent quality (standardised)
  • โœ… Meets high demand
  • โŒ Huge start-up costs (machinery, factory setup)
  • โŒ No variety โ€” products are all the same
  • โŒ Workers may get bored (repetitive tasks)
  • โŒ If the line breaks down, everything stops

โš–๏ธ Comparing production methods

Choosing the right production method depends on the business โ€” what it makes, how many it needs and what customers expect.

  • Job โ†’ unique, low volume, high cost per unit, high quality
  • Batch โ†’ some variety, medium volume, moderate cost per unit
  • Flow โ†’ standardised, high volume, low cost per unit, consistent quality
Exam tip: If a business switches from batch to job (or vice versa), think about how costs, quality, flexibility and worker motivation will change.

Factors influencing the choice

  • Nature of the product (custom vs standard)
  • Level of demand (low, medium, high)
  • Available budget for machinery and technology
  • Skill level of the workforce
  • Need for flexibility or variety
