A ‘theory of change’ explains how activities are understood to produce a series of results that contribute to achieving the final intended impacts. It can be developed for any level of intervention – an event, a project, a programme, a policy, a strategy or an organization. A theory of change can be developed for an intervention: • where objectives and activities can be identified and tightly planned beforehand, or • that changes and adapts in response to emerging issues and to decisions made by partners and other stakeholders.
