The Corporate Advisory Board (CAB) is the "Voice of the Corporate Customer" for INCOSE. CAB members provide:

• Guidance on overall INCOSE direction, focus, and priorities;
• A conduit between INCOSE and the sponsoring corporations for information exchange, key corporate systems engineering-related issues, and access to corporate executive management; and
• A bi-annual priority needs list and assessment of how well INCOSE is meeting those needs based on status inputs from the BoD and the Technical Board.
