An idea champion is a member of the organization who is assigned responsibility for the successful implementation of a change. The idea champion may be a senior manager or a non-manager, such as the inventor of the idea that has prompted the change. An idea champion will fight resistance to change and will actively pursue resources necessary to carry out the change. Idea champions may be critical to the success or failure of change. 

For example, Texas instruments reviewed 50 successful and 50 unsuccessful technical projects. One consistent finding was that every failure also lacked an idea champion. As a result, Texas instruments set up as its number one criterion for project approval the presence of an idea champion.
