Managing quality
What is quality?
Quality means a product or service meets or exceeds customer expectations consistently. It does not necessarily mean "the most expensive" — a budget airline delivers quality if flights are on time and safe; a Michelin-starred restaurant delivers quality at a different price point.
Businesses aim for quality because:
- Satisfied customers → repeat purchases → higher revenue.
- Good reputation → easier to attract new customers and charge premium prices.
- Fewer defects → less waste, lower warranty costs, reduced complaints.
Quality control (QC)
Quality control is a traditional, inspection-based approach. Finished products (or products at key stages of production) are checked against specifications. Defective items are rejected, reworked, or scrapped.
Advantages of QC:
- Simple to implement; clear pass/fail standards.
- Prevents defective products reaching customers.
Disadvantages of QC:
- Identifies problems after they occur — waste and cost of defective production already incurred.
- Requires dedicated inspectors — extra labour cost.
- Does not address the root cause of defects.
Quality assurance (QA)
Quality assurance is a system-wide approach that builds quality into every stage of production rather than only checking at the end. Every worker is responsible for quality at their own stage.
Key elements of QA:
- Process standards and documentation.
- Staff training so everyone understands quality requirements.
- Continuous monitoring and improvement (Kaizen philosophy).
- Supplier quality management — raw materials must also meet standards.
Advantages of QA:
- Reduces defects at source — prevention rather than cure.
- Improves morale: workers feel responsible for quality.
- Saves cost by reducing waste early in the process.
- More consistent output over time.
Disadvantages of QA:
- Complex and costly to implement — staff training and process redesign required.
- Takes time to embed into culture.
Total Quality Management (TQM)
TQM is the ultimate quality assurance philosophy — every employee, in every department, is responsible for quality at every stage. It requires a whole-organisation commitment to continuous improvement. Strongly associated with Japanese manufacturing (Toyota Production System).
Consequences of poor quality
| Consequence | Impact |
|---|---|
| Customer complaints and returns | Cost of handling, replacement, and refunds |
| Loss of reputation / brand damage | Negative reviews, social media criticism, reduced future sales |
| Product recalls | Extremely costly (logistical + reputational); examples: Samsung Galaxy Note 7, Bosch dishwashers |
| Lost repeat business | One poor experience drives customers to competitors |
| Legal liability | Consumer Rights Act 2015: products must be of satisfactory quality — businesses face claims if they are not |
| Higher long-term costs | Rework, scrap, warranty repairs all increase total costs |
UK example: In 2017 Bosch recalled thousands of dishwashers due to a fire hazard caused by a faulty component. The cost ran to tens of millions of pounds in logistics, replacement parts, and reputational repair — far more than a rigorous QA system would have cost.
Edexcel examiner note
Edexcel distinguishes clearly between QC and QA. Students often confuse the two — remember: QC = inspect at the end; QA = build quality in throughout. A question asking "recommend an approach to quality" requires you to name one, explain it, and justify why it is appropriate for the business's scale, industry, and context.
