Abstract: The concept of process approach and management factors were described. It illustrated that it was necessary to apply process approach to nondestructive testing because it was a method of evaluating the quality of special process product. During the process of nondestructive testing, the application of process approach could make the factor management more scientific, the process analysis more rigorous, and the process operation more normative as well as the evaluation of outstanding achievement more measurable. Therefore, the approach could control the quality of product and work effectively.
