PrD is an amazing risk reduction strategy, but it doesn’t apply in every situation. Successful PrD requires the right mix of talent: The internal team must be open to the process, and the process requires an effective facilitator. Further, the approach takes courage—airing our assumptions to external stakeholders with nothing more than cardboard, foam core, and glue is not for the faint of heart. Although PrD isn’t limited in how it can be applied, or to what type of project, it is most effective when the situation requires taking action first.
