This document discusses the importance of exploring requirements and addressing ambiguity before beginning the design process. It notes that without understanding what is being discussed, there is no point in being exact in the design. The document then provides examples of how the same short statement "Mary had a little lamb" can take on many different meanings depending on what requirements and assumptions are made. It advocates addressing questions around the client, goals, users, resources and timeframes to properly define requirements before choosing tools or coming up with design ideas.
