After all, haven’t we all witnessed a website crash during the time of a big eCommerce sale? Or, say, for instance, couldn't experience a seamless step-by-step flow when filling out a form online? These performance issues or unexpected shutdowns occur owing to improper quality assurance and software testing. chemical industry and related industries when I was the chief chemist of a manufacturing company...... even for products that are not chemical in nature... and quality management is anchored on certain principles  Quality Assurance Advanced Quality Planning Quality Systems Development Focus on Design Quality Costs Failure Mode and Effects Analysis Statistical Process Control  To continue...
