This blog post by Canadian public engagement firm Ascentum describes their Choicebook tool:
One online engagement tool that we put to use on a regular basis is something called a “Choicebook”, an innovative public participation tool that provides participants with the key facts, perspectives and arguments needed to make an informed choice about a given issue. With the necessary information at the tips of their fingers, participants are guided through a series of scenarios, and are asked to provide their ideas, perspectives and priorities, through a combination of open- and close-ended questions.
Our Choicebook™ tool can be hosted on a stand-alone consultation website, or launched from an invitation e-mail. We can even embed the tool within Facebook, to take engagement where possible participants are already converging on social media.
