GInI emphasizes that a portfolio approach to engagement mechanisms—such as Innovation Kits, Tournaments, or Panels—enhances participation by appealing to varied groups within an organization. TheCInP Handbooknotes that this approach leverages "a diversity of personalities, styles, perspectives, and capabilities" to ensure broad and effective engagement. This diversity allows the innovation program to tap into different ways of thinking and working, maximizing creativity and involvement. "A variety of languages" (A) is too narrow and not a focus of GInI’s framework. "A breadth of different demographics" (C) and "A range of intellectual capacities" (D) are less specific and not directly cited as the primary benefit in GInI documentation.
