Zhrnutie	Formative evaluation is evaluation conducted to improve a program, policy or product while it is still being developed or refined. The term was coined by Michael Scriven in his 1967 essay 'The Methodology of Evaluation', alongside its counterpart summative evaluation. Where summative evaluation renders a final verdict on a completed intervention, formative evaluation feeds timely information back to designers and implementers so they can fix problems, adjust components and strengthen the intervention before it is finalised or scaled.	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).
