By asking internal stakeholders to craft an artifact together, PrD shines a light on each team member’s assumptions. The process of revealing assumptions is, in and of itself, beneficial to the organization as it reduces potential misunderstanding early. But equally important to aligning internal teams around their (often hidden) assumptions, PrD asks teams to reveal assumptions to external stakeholders, enabling rich conversations with little investment.
Your assumptions are your windows on the world. Scrub them off every once in a while, or the light won’t come in.
