Standardisation to ensure consistency
What should a product be to be ‘good quality’?
Fit for purpose, Meet specification
Accurately produced
Appropriate use of technology
Appealing aesthetics
What is fitness for purpose?
Does it meet user requirements, safety standards and have a suitable lifespan
What is quality control?
Checking the product at various stages to identify and rectify defects
What is quality assurance?
Proactivity ensuring that quality is built into the design and production process to prevent defects
What are examples of control systems?
Sensors, automation or feedback loops
How do control systems help ensure quality?
Detect errors and improve efficiency
What is statistical process control?
Monitors production processes through data analysis to ensure consistency
Which standard is the standard for quality?
ISO 9000 is the international standard of quality
What is total quality management?
The concept of establishing attitudes of quality which filter through whole company not just manufacturing
How can quality control be carried out?
