2.3.3a Quality control and quality assurance Quiz: Pearson Edexcel Business, Unit 8

The 20 questions

1. What is quality control?

   • Writing the systems that set out how every process should be run
   • Checking finished products against a standard to find and remove faults
   • Selling products at the highest price the market will bear
   • Recruiting staff who are most likely to stay with the business for years

2. What is quality assurance?

   • Checking each finished item after it has already been made, packed and labelled for sale
   • Removing faulty products from the shelves once customers have complained about them
   • Measuring how much money the business spends on advertising and promotion each year
   • Systems and processes designed to prevent faults from happening in the first place

3. Which is an example of quality control?

   • Designing a new biscuit recipe for a seasonal product launch in the autumn range
   • Inspecting a sample of biscuits on a production line for broken or misshapen items
   • Writing a training manual that sets out how every biscuit should be baked in the oven
   • Negotiating a lower price with the supplier of the flour used in every batch of biscuits

4. Which is an example of quality assurance?

   • Counting the number of faulty items found by the end-of-line inspector each shift
   • Rejecting a batch of finished goods that contains several broken items at the end
   • Setting out a documented process that staff must follow at every stage of production
   • Measuring the weight of each packet of crisps after it has been sealed for sale

5. A factory makes 2,000 components and 60 are rejected at inspection. What is the reject rate as a percentage?

   • 3%
   • 30%
   • 0.3%
   • 6%

6. Why might a business use statistical sampling for quality control?

   • It is quicker and cheaper than checking every item, while still giving useful information
   • It removes the need for a quality standard to be set in the first place for products
   • It guarantees that customers will always rate the product as excellent in every survey
   • It means no faulty items can ever reach customers under any circumstances at all

7. Which is a benefit of quality assurance over quality control alone?

   • Quality assurance removes the need for any staff training programme
   • Products never need to be inspected at any point in production
   • Quality assurance guarantees the highest price for every product sold
   • Faults are prevented at source, so less rework and waste is needed

8. What is the main purpose of quality control in a business?

   • To ensure products meet the required standard before they reach customers
   • To decide how much profit the business will pay out to its shareholders each year
   • To choose which employees will be promoted to the management team each year
   • To set the price at which products will be sold in each of the business's markets

9. A service business uses a checklist to ensure every customer receives the same standard of service. Which quality approach is this?

   • Quality assurance, because it sets out a process to prevent variation
   • Quality control, because it only checks outcomes after the service ends
   • Marketing, because it tells customers what the business offers
   • Finance, because it records how much each customer has spent

10. Which is a consequence of poor quality control?

    • Customers pay less for goods because they are cheaper to produce
    • Customers receive faulty goods and may stop buying from the business
    • The business becomes more flexible because it can change products faster
    • The business reduces its costs because fewer inspections are needed

11. Which measure would a quality control team most likely record?

    • The number of staff who attend the annual Christmas party
    • The number of hours each director spends on the golf course
    • The number of pages in the company's annual report each year
    • The number of defective items found in each batch

12. A business uses a quality standard that says no more than 1% of items can be faulty. A batch of 800 items has 12 faults. Does it pass?

    • No, because 12 faults always means the batch fails the standard
    • No, because 1.5% of items are faulty
    • Yes, because 12 is less than 1% of 800
    • Yes, because 12 is a small number of items overall

13. Which is the best example of a quality standard?

    • A biscuit must be between 9.5cm and 10.5cm in diameter
    • A biscuit should taste good to most people who eat it
    • A biscuit should be made by a team that works well together
    • A biscuit should be sold in a box with a bright and cheerful design

14. Why is it important that quality standards are measurable?

    • So that the business can avoid paying taxes on its profits
    • So that staff can check whether products meet them consistently
    • So that customers stop asking for refunds on faulty products
    • So that the business can reduce the number of staff it employs

15. Which quality approach involves training staff so that they make fewer errors in the first place?

    • Statistical sampling
    • Quality assurance
    • Batch inspection
    • Quality control

16. A business finds 30 faulty units in a sample of 500. The business expects a fault rate of 5% or less. What should it conclude?

    • The fault rate is 60%, which means the sample must be discarded
    • The fault rate is 6%, which is above the expected level
    • The fault rate is 3%, which is well within the expected level
    • The fault rate is 0.6%, which is well within the expected level

17. Which is a risk of relying only on end-of-line quality control?

    • Faults are only found after time and materials have already been wasted
    • Customers are never able to report a fault they have found in a product
    • Staff are required to inspect every item at the end of the line each day
    • Faults are impossible to detect once the product has left the factory

18. What does 'rework' mean in production?

    • Recruiting new staff to replace those who have left the business in the last year
    • Reducing the number of hours that workers spend on the production line each week
    • Redesigning a product because customers have asked for a different colour or finish
    • Correcting faulty products so they meet the standard, which adds time and cost

19. A business introduces a quality check at each stage of production rather than only at the end. What is the main benefit?

    • The business no longer needs any staff to work on the production line at all
    • The business is able to sell its products without any packaging or labels at all
    • Customers are guaranteed to pay a higher price for each item they purchase from the store
    • Faults are caught early, reducing waste and the cost of correcting them later

20. Explain why quality assurance is often seen as more effective than quality control alone.

    • It prevents faults from being made, so fewer defective items need to be found and removed
    • It means customers will never ask about a product's quality again in the future at all
    • It makes inspection unnecessary, so the business can sell every item it produces without checks
    • It guarantees every product will be sold at the same price in every market the business enters
