Last week, you were introduced to the Steinitz Framework, and got a brief tour of the first iteration models. The focus on the first three models is assessment - understanding the study area context: representation models, process models, and evaluation models. This lesson will take a closer look at the last three models of the first iteration. These prepare us for intervention: change models, impact models, and decision models.
Change models ask you to look at potential outside influences and changes on the horizon for the study area. With these influences in mince, change models also ask the geodesign team to start envisioning alternative futures, or scenarios, for the study area. Impact models then ask us to weigh the potential consequences and benefits of each potential scenario. Finally, decision models ask you to identify the areas of conflict and concern among stakeholders that will influence how each scenario will be received. This will influence how your design solution for the area evolves and takes shape.
In this lesson, we look at an example from Ian McHarg to provide a contextual review of the first iteration of the geodesign framework. Then, we will borrow some techniques from Dr. William Haddon, a noted authority on automobile and highway safety and the first director of the National Highway Traffic Safety Administration, to learn to develop potential problem-solving strategies. Haddon developed ten strategies for reducing accidents. Although they were intended for highway safety, Haddon’s strategies have been applied across disciplines as a way of brainstorming solutions to complex problems. For our purposes, Haddon’s strategies will help us rapidly develop alternative strategies to solve a geographic problem related to your individual AOIs.
