"Officials reported that assessing the cost of JIE is complex because of the size and the complexity of the department's infrastructure and JIE's implementation approach," the report said. "However, without information about expected JIE costs, the ability of officials to oversee and make effective resource decisions is limited."
The report also criticized the Department of Defense for its inability thus far to determine the staff and skills needed to operate the new system.
"As a result, DOD [Department of Defense] risks having a deficient security posture and not being able to ensure that it will have the appropriate workforce knowledge and skills needed to support JIE," the report explained.
The report recommended that the Pentagon fully define the single network 's scope and expected cost, and take steps to improve workforce and security planning.
