Some thoughts related to incremental housing vs. traditional approaches in the case of Haiti.
1) People could get homes built initially much more quickly because they are building less. However, there would probably need to be as much planning up front. But once, a system or framework is in place, the planning doesn't have to go on and on, it can be tweaked for each place or context....without creating cookie cutter mass produced stuff. That is what is beautiful about it....it can take on a life of its own, and have individuality, culture, context, and place embedded in it without the architects designing it in. Also, like many good projects, there will need to be deep community involvement. Incremental housing would allow such involvement to exist, but keep it more focused and take up less time, which is critical in this case.
