Choose an operations method
Compare job, batch, flow and mass-customisation methods and anticipate the problems of changing production approach.
Cambridge International AS & A Level Business 9609, 2026–2028 syllabus and 2029 syllabus, section 4.1.4. Cambridge states that both current versions have no significant changes affecting teaching. This lesson maps only its named section; other sections and full paper practice remain separate. Written practice is self-checked
Before you begin
- No previous business course is assumed. Use the lesson's definitions before applying them to the business context.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Which method makes distinct products for individual requirements?
What you will learn
- Describe four operations methods
- Compare their suitability and trade-offs
- Explain problems involved in changing methods
Methods balance variety and volume
Job production makes a distinct product or service for a customer, often with high variety and low volume. Batch production makes groups of similar items before switching to another batch. Flow production moves standardised work continuously through sequenced stages.
Mass customisation uses flexible processes or technology to provide customer variation while retaining some scale efficiency. It differs from pure job production because the business seeks repeatable custom options within a broader system.
Changing methods creates transition risks
Method choice affects equipment, layout, skills, scheduling, quality checks, inventory and customer lead times. Job methods can support uniqueness but require skilled time; batches allow variety but involve changeovers; flow supports volume but can become rigid; mass customisation needs reliable information and flexible systems.
A shift in method may require investment, staff training, supplier changes, process testing and temporary disruption. Consider whether demand is stable enough, whether employees and suppliers can adapt, and how quality will be protected during the transition.
Pause and explain
A factory makes 500 identical bottles in a continuous sequence. Which method best fits?
Worked example
A print shop makes bespoke wedding invitations and is considering standard invitation batches with customer-selected colours. Compare the current and proposed methods.
Show the worked solution
- Bespoke individual designs resemble job production.
- Groups of standard designs with colour options could use batches or mass customisation.
- Check setup, ordering accuracy, variety and customer demand.
Answer The current one-off work is close to job production. Standard designs produced in groups could use batch production; digital templates that personalise names and colours within a repeatable process could be mass customisation. The shop should test whether the reduced setup time outweighs limits on design choice and system costs.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A furniture business produces 25 identical chairs, then changes to a different design. Identify the method and one operational consequence.
Give me a hint
Look for a group of similar items followed by a changeover.
Compare my reasoning
- A group of similar products is made together.
- This is batch production.
- Changeover time or setup cost may reduce productive time.
This is batch production. Changing designs may require machine setup, material changes and quality checks, creating changeover time or cost between batches.
Look for these in your work
- Method is correctly identified
- Batch feature is explained
- A trade-off is named
A meal company offers customers a choice of sauce while preparing the base meal using a standard process. Explain how this could be mass customisation and one requirement for success.
Give me a hint
Separate repeatable core production from customer-specific options.
Compare my reasoning
- The common base supports standardised work.
- Selected sauces create controlled variation.
- Accurate order information and dependable assembly are needed.
It can be mass customisation because the company combines a repeatable base process with a limited customer choice. Accurate order capture, ingredient availability and final checks are needed to deliver the selected sauce correctly.
Look for these in your work
- Standardisation and variation are both described
- A success condition is operational
- Customer choice remains bounded
A business plans to switch from job production to flow production. Explain two risks during the transition and how it could reduce them.
Give me a hint
Consider people, equipment, layout and delivery while the new process is tested.
Compare my reasoning
- New equipment or layout may disrupt current output.
- Workers may need new skills and quality checks.
- Pilot the line, train staff and keep a transition plan for existing orders.
The layout change may interrupt production and workers may be unfamiliar with the new sequence, raising defects or delays. A pilot line, staff training, revised checks and a plan for open customer orders can reduce disruption before full conversion.
Look for these in your work
- Two transition risks are explained
- Mitigation is practical
- Existing customers or quality are protected
Common mistakes
- Calling batch and flow the same because both repeat tasks
- Treating mass customisation as unlimited bespoke design
- Ignoring disruption and training when changing a method
