The Defense Department‘s efforts to reform its services acquisition system could take another 12 years to reach full implementation, Federal News Radio reported Monday.

Scott Maucione quotes Ken Brennan, DoD deputy director of services acquisition, who said the department is three years into a potential 15-year reform plan that aims to enhance the way DoD procures services.

“My goal is that services [contracts] become less of a standalone and just more of the general culture and policy,” Brennan said at a Professional Services Council event Monday.

He added the department works to implement a guideline that was released in January, which seeks to create Services Requirement Review Boards, drive services acquisition to focus more on portfolio and allot more decision-making authority to military acquisition chiefs, Maucione wrote.

The guideline also works to establish “functional domain experts” to oversee the services sectors, the report said.

Brennan noted the U.S. Air Force appears to be the most improved in applying the January instruction, particularly for organizational health assessment, Federal News Radio said.
