"Evaluation of the success of planning outcomes or the planning process itself is usually undertaken after the plan or project is complete, if at all. I find it unfortunate that evaluation is separated in time from participation. Evaluation of the success or failure of plans and participation processes can, and should, take place early in the process, in conjunction with not after public input. In short, I argue that planners need to evaluate with the public as plans and projects move forward. I also offer some suggestions for better integrating evaluation into public participation processes."
