Quandry: Quandary is an application for creating Web-based Action Mazes. An Action Maze is a kind of interactive case-study; the user is presented with a situation, and a number of choices as to a course of action to deal with it. On choosing one of the options, the resulting situation is then presented, again with a set of options. Working through this branching tree is like negotiating a maze, hence the name "Action Maze". Action mazes can be used for many purposes, including problem-solving, diagnosis, procedural training, and surveys/questionnaires.
