Observations
Agencies own and certify a large number of devicesMany agencies use their own procedures & facilitiesMost agencies do not accept other agencies’ certificationSome agencies apparently do not certifyPerceived value of certification is credibility, technical validityPerceived value for both network & project workTravel authorization, distance, & cost are potential barriers to regional certification facilitiesSurvey results may change post MAP-21
