So in the scenario mentioned above, the first part about the release with multiple bugs would point to an under forming Quality Control system where the testing conducted did not help fulfill requirements. So the QMS is the framework within which QA (preventive) and QC (detective) functions operate to meet the quality goals.The rest of the infographic shows how the three get engaged within the project lifecycle. QC is the area of quality management that ensures that requirements for products, services and as specified by the customer are fulfilled.QA is the division of quality management that ensures that planned process steps were followed during the actual execution.QMS is a set of policies, processes and procedures needed to set up the quality infrastructure of an organization in terms of people, process and tools.As shown in the infographic, let's start at the beginning. In essence QMS, QA and QC are all related but are definitely not the same, and as such, should not be used interchangeably. However, an accurate understanding of these concepts could create the awareness needed regarding quality expectations and responsibilities, necessary for successful projects.


Project team members are used to seeing and hearing these terms being used interchangeably and often incorrectly. There seems to be an element of inconsistency when using the terms QA, QC or Quality Management System (QMS) on IT projects. Question - do you think he should be looking at his Quality Assurance (QA) or Quality Control (QC) area to fix the problem going forward? What if this was the second consecutive release on the project with a similar negative outcome? The PM thought he had addressed the problem from last time by adding more testers for the current release, but it looks like that did not stop the issue from recurring. His team is rushing to address all the bug reports that are coming in, as he is trying to figure out what went wrong. Consider this scenario - a project manager on a software development project is getting negative reviews from his customer on the latest release due to the large number of bugs.
