To develop standards that will enable:

• Reduction of costs• Improved product quality and time to market• Optimized economical allocation of resources

amongst specification, manufacturing and verification

• Proper implementation of GPS, which is important for companies in surviving in a global competition

The Vision ofISO/TC 213 Dimensional and Geometrical Product Specification
