Everyday things we take for granted only fulfil our expectations because they have been through some form of quality assessment.
Objects such as:
- Alarm clocks which correctly display time and sound the alarm to the exact hour and minute it is set for.
- Toasters which will toast bread for 3 minutes as set and not burn the toast into a charcoal mess.
- Microwave ovens which will cook a bowl of beans within thirty seconds instead of cooking the innards of the person using the microwave.
- Traffic lights that change colour according to traffic flow instead of sticking on red and causing complete gridlock.
- Train doors that open only when the train is stationary at a station instead of opening when the training is moving.
All these products mentioned above work because they have been through some form of quality assessment. The quality assessment methods used may vary from product to product but essentially involve similar principles.
Quality assessments are done to ensure the products are fit for the purpose they were designed for.
