The correct answer is A. Challenge campaigns. In Stage 2 of the GInI Innovation Management System, idea capture is treated as a continuing activity, but organizations generally get stronger and more relevant results when idea generation is directed toward a defined need, theme, or strategic priority. This focus helps employees and contributors concentrate their thinking on areas that matter most to the business.

Challenge campaigns are a structured way to do this. They invite participants to submit ideas in response to a clearly framed question, opportunity area, or business challenge. By narrowing the scope, the organization improves the quality, relevance, and usefulness of the ideas that enter the system. This also makes idea evaluation more efficient because submitted ideas are more closely aligned with current objectives.

The other options do not reflect a formal or effective mechanism for focused idea capture within an innovation management system. Secret projects are unrelated to broad participation. Inspirational advertisements and games may raise interest, but they do not provide the structured focus needed for sustained idea capture. Challenge campaigns are therefore the most appropriate method for concentrating innovation input around a particular area.
