"Every community needs a roadmap for change. Instead of bridges, avenues and freeways, this map would illustrate destinations of progress and the routes to travel on the way to achieving progress. The map would also provide commentary about assumptions, such as the final destination, the context for the map, the processes to engage in during the journey and the belief system that underlies the importance of traveling in a particular way. This type of map is called a "theory of change." The label theory of change is often referred to by other terms, such as pathway of change, engine of change, blueprint, logic model and theory of action. Regardless of the label, a theory of change offers a picture of important destinations and guides you on what to look for on the journey to ensure you are on the right pathway." (Introduction)
