Theory of Change
Theories of change explain the central process by which change is expected to occur for individuals, groups or communities. They can be rooted in evidence based research, or a new idea that merits exploration.
Some programs aim to reduce or prevent change from occurring, such as maintaining mobility for an aging individual. Here, theories of change explain how pressure to change will be resisted.
When a cause and effect link is clear, evaluation can be applied to determine the impact of these ideas and the programs or projects they create.
