RESUMO
Theory of change (ToC) is an approach widely used to guide planning, implementing, and evaluating change initiatives. While there is substantial guidance, there has been little attention on equity within ToC research and practice. We propose and illustrate the metaphor of 'knots' to frame practical and ethical challenges that arise when centering equity within ToC processes. Drawing on our experiences using a ToC approach in two case examples, we identify and illustrate five equity-related knots: (a) clarify root causes, pathways, and success; (b) facilitate participation across power and perspective differences; (c) integrate research evidence and practitioner knowledge; (d) represent complex change visually; and (e) creatively navigate constraints. We show why framing these as knots can help practitioners make wise judgments within the circumstances and close with recommendations for including knots in ToC processes, reporting, and guidance.
