DAPA has implemented a revised version of the Defense Acquisition Program Management Regulation as of October 6. The main revisions in the regulations are as follows: First, with the purpose of enhancing program management, the item of program management factors is included in preliminary research to identify risk factors in program management and plan ahead. Second, safety standards have been strengthened by mandating DTaQ quality certification for military explosives. In addition, sole source contracts have been limited in ship exploratory developments up to the stage of production. Details can be referred to at the DAPA website.
