EVMS Compliance and Surveillance is primarily governed by processes established at the DCMA EVMS Center. Business Practice 4 - EVMS Surveillance describes the 5 groups of metrics to be periodically evaluated based on perceived system risks. Business Practice 6 - Compliance Review Execution describes the approach for determining system compliance with all 32 guidelines in the EIA-748 standard, and will require delivery of all related system documentation and data. TMS helps customers organize and automate their data collection processes to make these reviews go as smoothly inexpensively as possible. We also recommend process improvements and support any corrective actions needed to address findings.
