The Information Technology Acquisition Board (ITAB) is the decision forum for Milestone review of Acquisition Category (ACAT) IAM programs. The ITAB contributes strategic-level insight for net-centric, Global Information Grid (GIG), and Information Technology issues when they cannot be resolved at the Overarching Integrated Product Team (OIPT) level. The ITAB facilitates execution of the Milestone Decision Authority’s (MDA) acquisition-related responsibilities for Information Technology.
The ITAB reviews should focus on key principles such as: 
- Support of mission needs as described in the Strategic Planning Guidance (SPG) and the Joint Programming Guidance JPG), Joint Vision 2020, the DoD Information Management and Information Technology Strategic Plan 2008 – 2009, the operational view of the approved Global Information Grid (GIG) Integrated Architecture, and the approved Global Information Grid (GIG) Capstone Requirements Document
- Compliance with the Department of Defense Enterprise Architecture (DoD EA)
An Acquisition Decision Memorandum (ADM) documents the decision(s) resulting from the review.
