That’s why this phenomenon is process oriented because it deals with prevention of errors in the production process before a product is completely developed and produced. For example whenever a software is started to develop, while the process of developing the measures and checks used for assuring the quality of the software and preventing the errors and bugs, all these phenomena is categorized under quality assurance.
