An inspection and test plan, or inspection test plan, is a document or series of documents used for quality assurance purposes.
Meeting requirements and customer satisfaction is the ultimate goal of a quality management system prepared and designed by a company.
As part of quality assurance and control measures, inspection, test and measurement activities should be planned, defined and carried out in a documented manner (ITP - Inspection and Test Plan). This minimizes the risks of products and any deviations can be detected early in the manufacturing process.
It serves as “a bridge” between Quality Assurance and Quality Control, covering activities before, during and after the process of the product realization (i.e.: manufacturing, fabrication, construction, installation).
It ensures that the quality level of the product is within the acceptable design standards and requirements.
