I am finding it very useful for planning public consultations required for environmental assements. The detailed Roadmap Model gives 51 key steps one should carry out to conduct a successful public participation process. Written in 1997 it's a bit out of date in terms of more conteporary approaches, such as the use of online tools, but it is still very worth while and insightful for consultants and government folks in Canada and beyond. Pass it on!
