Quality Flashcards
What is process validation
Process validation means establishing by objective evidence that a process consistently produces a result or product meeting its predetermined specifications.
Benefits of PV
- )Allows you to ensure that the product meets requirements when 100% inspection is not possible
- )When failure is difficult to detect or impossible to checked after the process
Difference between process capability and SPC
PC gives you a measurement of whether a process can produce in specification product at one point in time
While
Statistical process control monitors average and range, a fixed intervals, over a long period of time
4 aspects of a SPC
- )Measure the same number of parts of fixed time intervals
- )Calculate average and range of average and standard deviation for each group
- )Calculate position of control limit using tables
- )All points are inside the limits and appear random than the processes are in control
ISO 9001
A quality management system. Has procedures for everything and responsibilities are distributed amongst employees.
Process capability index CP
Cp= USL-LSL/6sigma
What does distribution need
- )A lower limit
- )A mean
- )A upper limit
Differences between TQM and six Sigma
- )TQM is focusing on customer satisfaction while six Sigma focuses on continuous improvement on the benefits gained even after the goals has been achieved
- )Blackbelt who have gone through formal training and have a proven track record in quality gains manage six Sigma projects while TQM is managed by the quality control department and those professionals are specialized on quality improvements
- )TQM is a concept associated with process improvements by reducing the effects errors and waste in organisations while six Sigma is a concept the focuses on continuous quality improvements for achieving near perfection by limiting the numbers of possible defects to last 3.4 defects per million
MAIC
Measure analyse improve control
To what does six Sigma refer?
Six standard deviations between mean and specification limit
Customers focus and employee involvement
What is Six Sigma
Quality improvement technique that aims to reduce the defect levels
TQM
Top Quality Management
Implies:
Top management lad companywide approach involving all employees and focusing on prevention rather than detection or correction.
Customer orientation and teamwork our key features
Lean manufacturing
Central idea
1.) reduce waste by removing or reducing tasks which don’t add value for the customers viewpoint three categories, value creating, incidental and waste
What are the three Quality Philosophies
- ) Lean manufacturing
- )TQM
- )Six Sigma
Define Engineering Quality
Quality is conformance to requirements or specifications
