Quick inspection and examination of the prototype by various analytical techniques could lead to fully understanding the material functionality and properties. Examples: determination of the variation of Ti and N ratio across the TiN coating; chemical change of polymer surface before and after modification; confirmation of the construction of magnetic storage media.

Make use of proper analytical techniques could lead to fully understanding the failure of product. Examples: analysis on the surface contaminant could trace the origin; detection of discoloration, surface morphology, crack, pit or void could trace the abnormality of process parameters. 

Development of adequate analytical technique to govern the manufacturing process parameters in order to avoid producing non-conformance product. Examples: periodic inspection of plating thickness could confirm whether the deposition process within the product specifications; checking fineness of the precious metal coating could could trace the discrepancy of process parameters.
