Quality assurance
QA is process-oriented. It is a proactive measure that focuses on preventing any defects or any possible issues that may occur. QA assures proper implementation of the right techniques and methods designed for every project. QA activities, like process standards and documentation, and project audit recognize errors in the process. This comes first before quality control.
QA is a low-level activity that can identify mistakes which QC can not. It is the responsibility of everyone on the team involved in developing a product.
