Iterative design acknowledges that the world is constantly changing and so are its people. Shifting preferences, lifestyles and work ethics mean that initiatives relying on people need to be designed to accommodate changes. They need to suck up their pride and understand that sometimes, some things will fail. This type of design prescribes a curiosity for the unknown at all times and involves lots of questions on an hourly basis. It also calls for the embodiment and ownership of the design as changing in and of itself. (Thanks, Twaweza !)
