Previously, we've talked about the heirarchical list of information: product level, device level, feature level which just captures one aspect of the fixed things in the product (that don't change with time). Its an incomplete picture - so then we have to take each feature/functionality "name" and treat it as a systems and signals block. Then determine how they're related to each other and what flows between each block - how the information flows from internal, to external, and displaying how that works. In this episode, Cindy and Malcolm discuss systems thinking as applied to product development.
