The OSA, along with commercial and technical assessment, is part of HCH’s supplier approval process and should be applied in the following situations- Before any business is awarded to a new supplier to HCH- Whenever there is a significant change in an approved supplier’s operations, such as plant relocation or change of ownership. Periodically, as determined by HCH, in order to ensure continuation of supplier’s quality management systems. Also, OSA may be completed for a currently approved supplier as a prerequisite for other Part Qualification activities, especially where the design or manufacturing process of the new components is significantly different with earlier approved components. HCH is used to evaluate a supplier's quality systems and is an integral part of the HCH supplier approval process.
