Quality assurance (QA) is activities designed to ensure that quality is built into the process. 3. Introduction to probability theory; random variables, distributions, functions of random variables, models of failure of components, reliability, redundancy, complex systems, stressstrength models, fault tree analysis, statistical quality control by variables and by attributes, acceptance sampling. Therefore, the need for a … One really vital piece of the development process is product testing for quality, reliability and durability. One of the key drivers of quality is the performance of the product over a period of time. The importance of true physical acceleration life models (accelerated tests = true acceleration or acceleration) 3 1.1.2. Have no quality standards and reliability becomes a matter of luck. Specification of quality is a must for quality control. Each export consignment in packed condition is subject to detailed inspection to ensure conformity to the recognized specification.
