Summary of Changes

• The basic measurements and reporting processing remains unchanged. There are minor modifications and clarifications to the common (NPR, FRT, OFR, and OTD) measurements as well as the field returns (FR) measurement. The system outage (SO, SONE, EIO) measurements were simplified. The software (SFQ, SPR) measurements were considerably changed and shortened.  The service quality (SQ) measurement was also simplified, applied to additional product categories, and changed to report defects.
