They both have their own roles. The group came to a consensus that the role is, as Mr. Ray mentioned, to change organizational culture. But this is a difficult thing to do because usually that means changing tradition, which is very difficult to change. Traditions have long-standing background associated with them, and people can only change them slowly, over time. Organizations need to make changes at every step they can, but they can't expect things to happen in just 1 day.
Diversity is an evolutionary rather than revolutionary process.
The key to that evolution is, as Paul's group said, convincing management and the people in the organization that it is in the organization's best interest to change. An organization can become more effective and better able to meet its mission, by having a diverse workforce. The final point the group made was also very similar to one made by Paul's group. Some organizations needs to take leadership and push for this evolutionary change. Even though change happens over time, agents of change are needed.
