In this first important step, a QA technician will set clear objectives to make high-quality end products and propose appropriate processes to implement those goals. [1] This defect prevention in quality assurance differs subtly from defect detection and rejection in quality control and has been referred to as a shift left since it focuses on quality earlier in the process (i.e., to the left of a linear process diagram reading left to right). QA has been a critical component of any software development. QA exists in many industries such as food, manufacturing, and pharmaceutical. This in turn is supported by quality management practices which can include a number of business systems and which are usually specific to the activities of the business unit concerned.
