Emily begins by analyzing the composition of her existing group. The fact that they have a solid history of working well together makes her question whether they have enough intellectual diversity to foster "creative abrasion." After examining their thinking styles and skills, she finds a few gaps. Emily then looks for people, internally and externally, who can fill those gaps. She adds temporary team members who cross functional boundaries. She invites outsiders to attend meetings and creates a weekly lunch seminar with invited guests. Eventually, Emily gets results: different ways of approaching problems, plenty of ideas—and some strong disagreement.
