What is quality control?
The process of inspecting products to ensure that they meet the required quality standards
The traditional way of managing quality
Involves checking and reviewing output
Mainly about ‘detecting’ defective output- rather than preventing it
Usually requires sampling
Spots and removes sub-standard output
It can be very costly
What is quality control and inspection?
When raw materials are received before entering production
Whilst products are going through the production process
When products are finished- takes place before products are despatched to customers
What are the benefits of quality control?
Sub-standard output is spotted before it reaches the customer
Minimise disruption to production
Applies a consistent standard of quality
What are the problems with quality inspection?
Costly
Often at the end of the production process- i.e potentially too late
Inconsistent inspections
Often not compatible with modern production systems
Done by inspectors rather than workers themselves
