The decision to change the CIO portfolio was made several months ago, the department said, in a move designed to reorganise the way DIE is managed. The new CIO role will encompass all aspects of DIE management, according to the department, including "strategy, planning, prioritisation, development, implementation and support".
Secretary of the department, Ric Smith, said the CIO group will now provide a single point of authority and accountability for the DIE.
"This will enhance the control and prioritisation of DIE spending and will mean that strategy, development, procurement and support of the DIE will be closely tied together," he said.
"These changes will mean a much stronger, more focused and accountable information environment in Defence."
Monaghan was previously the head of the Aerospace Systems Division with the department. According to Smith he is "well positioned to lead the CIO group" due to his skills and years of experience with the ADF.
