SO YOU WANT A CMMC CERTIFICATION (PART FOUR)

PART FOUR:

The IV&V Group® is preparing to meet the requirements imposed by the CMMC.  We are a sub-contractor for a number of federal government contracts.  As we make our own way through the CMMC requirements we hope that our understandings, as illustrated below, will help others with their understanding.

There are 17 Domains* and each one has multiple capabilities.  Rather than list all of them we have selected one domain and shown how the specific practices required to satisfy that capability vary depending on the desired level of maturity.
