The Veterans Affairs Department sees advantages in using open-source software to modernize its Veterans Health Information Systems and Technology Architecture (VistA) system, but it anticipates several problems if it takes that step. The VA issued a request for information Aug. 11 asking for industry to deal with anticipated concerns related to open-source development for VistA. The request follows a recommendation from an Industry Advisory Council working group in May 2010 that the VA create an open-source development program to update VistA. VA Chief Information Officer Roger Baker has invited the group to submit advice on modernizing VistA.
