Hivos values working with Theory of Change (ToC) as an appropriate approach to guide its strategic thinking and action, as well as its collaborative action with others. The use of a ToC approach fosters critical questioning of all aspects of change interventions and supports adaptive planning and management in response to diverse and quickly changing contexts. It contributes to the quality and transparency of strategic thinking, and therefore to personal, organisational and social learning. Use of a ToC approach should make Hivos more effective in achieving its goals, and enable it to understand better why and under which conditions specific strategies might work for specific groups in society.
