- Method aimed to check the quality of the product. A typical control process is performed on a single component, a sub – component, and a finished product.

- Organizational or programmatic level. at the organizational level, QA activities ensure that the program or organization is successful by overseeing the infrastructure necessary for individual projects in the program, and making sure activities have the resources they need to be successful.
- Project Level. At the project level, QA activities support the success of an individual project by ensuring that accurate information is channeled to the right people at the right time so that decisions can be made during project implementation that are defensible and cost-effective.
- Technical Level. At the technical level, QA activities ensure that the individual technical activities that generate, process, or synthesize data (or other information) for the decision process are performing within accepted limits. These activities are also commonly known as quality control (QC).
- Quality assurance involves the planned and systematic actions necessary to provide confidence in each analytical result. The QA/QC Program has two components: Quality Assurance (QA) – the system used to verify that the entire analytical process is operating within acceptable limits and Quality Control (QC) – the mechanisms established to measure non-conforming method performance.

Quality control ensures that equipment is working properly, that the operator is performing appropriately, and that malfunctions or false readings do not go undetected.
