  6. Two designs: one centralizes most of the responsibilities into a FrontPanel object. The decentralized design models ideas like product, ingredient, recipe and spreads the functionality over 12 modules.
  7. Overall correctness on 4 tasks: 59%, correctness increases with expertise, centralized(69%) done correctly more often than decentralized(50%)!
  8. Effort drops with expertise for students, but for consultants the effort on decentralized design drops with expertise and increases for the centralized.
