Production processes

How a business produces its goods or services affects unit cost, flexibility, quality and capacity. Edexcel 1BS0 examines three production methods plus the role of technology and three operational metrics (productivity, efficiency, flexibility).

Job production

One unit at a time, made to order. The product is unique or highly customised.

Examples: tailored suit, wedding cake, bespoke architect-designed house, hand-built sports car.

Pros: highly customised, premium prices, motivated workers (variety). Cons: slow, expensive per unit, requires skilled labour.

Batch production

Grouped units of the same product are made together, then a switchover to the next batch.

Examples: bakery making 200 sourdough loaves Monday and 200 baguettes Tuesday; a clothing factory producing one size/colour run before switching to the next.

Pros: lower per-unit cost than job; some variety; allows make-to-stock. Cons: switching between batches creates idle time; partly-skilled workforce; stock holding cost.

Flow production

Continuous, uniform production of identical units on an assembly line.

Examples: car production lines, bottling plants, pharmaceutical packaging.

Pros: very low unit cost (economies of scale), consistent quality, high output. Cons: high set-up cost (machinery), inflexible — switching to a different product is expensive and slow.

Role of technology

Technology has transformed production:

• Robotics & CAM (Computer-Aided Manufacturing) — automate flow lines; consistent quality.
• 3D printing — makes job and small-batch production fast and economical (medical devices, prototyping, dentistry).
• CAD (Computer-Aided Design) — speeds product design and reduces errors.
• EPOS / RFID stock systems — link production to real-time demand, reducing waste.

Productivity, efficiency, flexibility

• Productivity = output per worker (or per machine, per hour). Higher productivity = lower unit cost.
• Efficiency = output relative to input (raw materials, energy, time). Reducing waste improves efficiency.
• Flexibility = ability to switch between products, volumes, designs. Job production is most flexible; flow production is least.

Trade-offs

Businesses must trade off these dimensions:

• Flow production is highly productive and efficient, but inflexible.
• Job production is flexible and high-quality, but expensive and slow.
• Batch is the middle ground — most UK SMEs use batch.

Edexcel exam tip

When identifying the best production method, look at the scenario for: volume (how many units?), customisation (unique vs identical?), price point (premium vs commodity?), and capital available (machinery costs vs labour).
