Every process in Quality Assurance involves the PDCA (PLAN Do Check Act) cycle, often known as the Deming cycle. The FOLLOWING are the phases of this cycle:

• Plan: The organisation should plan and develop process-related objectives, as well as the methods necessary to provide a high-quality FINAL product. Here, Quality Assurance ensures that the planning MADE takes into consideration the quality of the product.
• Do: This phase involves process development and testing, as well as "doing" changes to processes. Here, Quality Assurance ensures that the processes followed during development maintain the quality of the product.
• Check: In this phase, processes are monitored, modified, and checked to see if they achieve the INTENDED goals. Here, Quality Assurance ensures that the processes are checked thoroughly so that no defects might be missed.
• Act: In this phase, a Quality Assurance tester should take the steps that are required to improve the processes.

These stages are done to guarantee that the organization's procedures are assessed and improved on a regular basis.
