Through his work in the previous weeks, Will was interested in depicting his design activity through the project management body of knowledge model (see Dubberly). Arrows represent the direction of progress, and the size of each stage represents the time it took. A small tweak he made was for that last arrow from Closing Processes to Planning Processes, because sometimes he actually finishes his process but then decides to go over to Planning Processes just one more time. See the back of the postcard for the key and other details!
