What is Quality Assurance (QA)?
Procedures to manage all functions that affect quality.
Quality Assurance does not check the quality of the final product, but the quality of all systems on the production line, staff training and quality monitoring.
What is Quality Control (QC)?
The process of inspecting products to ensure that they meet the required quality standards. It may take part in any part of the production.
What is tolerance?
The acceptable range of difference from standard.
What is one-off production?
It is a product that is made one time. These products are expensive at cost price and often take a long time to make and cost of materials & labour are high. A lot of prototypes are one-offs.
What is Batch Production?
These products are identical and produced in small batches, daily, weekly, monthly or when needed. They can range in price. Production normally runs from between 2 - 10k products.
What is Mass Production?
These products are produced in very high volumes, usually more than 10k. They are normally products that are in high demand and can range in expense.
Cars are a good example.
What is Continuous Production?
These items are normally very cheap to make and could be considered ‘throwaway’. These factories are often found in developing countries where land for factories and equipment are cheaper.
What is Just in Time Production (JIT)?
This scale of production relies on the product being manufactured to a time schedule. This allows raw materials to be delivered at an exact time for production and then manufactured and are shipped straight to distribution/retailers. Apple uses JIT production.
