Why quality matters
Quality means a good or service meets the standards that customers expect. Good quality builds a strong reputation, encourages repeat purchases and lets a firm charge a higher price. Poor quality leads to complaints, returns, refunds and lost customers, which is costly and damages the brand.
Key idea
Quality is about meeting customer expectations reliably. The cost of getting it wrong — waste, reworking and lost sales — is usually greater than the cost of preventing faults in the first place.
Two approaches to quality
Quality control (QC) checks products at the end of the production process and removes any that are faulty. It is simple, but faults are found only after resources have been used, so waste still occurs.
Quality assurance (QA) builds checks into every stage so that mistakes are prevented as work goes along. Workers take responsibility for their own quality, which can reduce waste and improve morale.
| Quality control | Quality assurance |
|---|---|
| Inspection at the end | Checks at every stage |
| Faults found late | Faults prevented early |
Example
A phone maker adopts total quality management (TQM): every employee, from design to delivery, is responsible for quality. Fault rates fall and fewer phones are returned, protecting the firm's reputation.
Consequences of quality
High quality supports a strong unique selling point and customer loyalty. Poor quality raises costs through waste and can lead to legal action if products are unsafe.
Remember
- QC = inspect at the end; QA = prevent faults at every stage.
- TQM makes quality everyone's responsibility.
- Preventing faults is usually cheaper than correcting them.
