The Department of Defense and the National Institute of Standards and Technology held a Model Based Enterprise Summit and Technical Data Package (TDP) Workshop December 15-17, 2009 in Gaithersburg, MD. The TDP workshop gathered subject matter experts to make recommendations for changes to DoD technical data package specifications. These changes are needed to support DoD transition to total lifecycle management based on digital models rather than 2D drawings. 77 subject matter experts from government and industry identified 46 critical issues affecting adoption of model based technical data packages during the day and a half workshop. Issues were separated into four acquisition, production, sustainment, and policy. The attendees developed 148 proposed actions needed to address the critical issues.
