The Crawford’s Slip process has become more popular in recent times. The meeting procedure is that of the brainstorming technique. Advantages of this approach include the lack of any limit on the number of participants and the reduced burden on a facilitator. Its advantage is that it produces a lot of ideas very quickly. On individual pieces of paper (Post-It-Notes are popularly used), participants write down a single suggestion in answer to a facilitator-posed question such as: "What risks could you could anticipate during this project?" There might be 10 suggestions each from 10 participants, creating 100 answers to the one question that are subsequently filtered and grouped under more or less common rubrics. The entire process can take as little as half-an-hour for a small group, but it gets longer faster for larger groups.
