Compliance to Standard
Validate your new design and compare it to standard and norms such as TIA, ISO, etc
The outcome is a report which will indicate the level of compliance and what potentially need to be addressed to ensure that an audit will go smooth and leads to certification.
This design validation review will enable you to correct parts of your design to avoid potential non-compliance with applicable standards avoiding the often very expensive construction changes or issues during an audit which would result in a potential non-compliance and therefore no certification could be obtained.
