সারসংক্ষেপ	Developmental evaluation is an approach designed to support innovation and adaptation in complex, dynamic environments where the intervention itself is still emerging. Articulated by Michael Quinn Patton in his 2011 book, it abandons the assumption of a fixed, pre-specified model to be tested, and instead embeds an evaluator within the design team to provide real-time feedback that informs ongoing development. Its purpose is development — helping social innovators learn, adapt and respond as conditions change — rather than the improvement of a settled program (formative) or the judgement of a completed one (summative).	Theory of change evaluation is a theory-based approach that evaluates a program against an explicit map of how and why it is expected to produce its intended outcomes. Rooted in Carol Weiss's work on theory-based evaluation and the Aspen Institute's community-initiatives projects of the 1990s, it requires evaluators to articulate the full causal pathway from activities through short- and intermediate-term outcomes to a long-term goal, make the underlying assumptions explicit, and then collect evidence to test whether each link in that chain holds in practice. The theory of change serves simultaneously as a planning tool and as the framework against which the program's progress and plausibility are judged.
