This paper provides a case study of the use of the Cynefin framework in evaluation planning. The Cynefin framework is a systems thinking tool that can be used to describe evaluation situations. The framework describes four types of dynamics and corresponding types of inquiry. The paper outlines three steps for using Cynefin in selecting evaluation methods and approaches. Benefits to evaluation practice include: 1) Seeing various causal dynamics operating in a single evaluation situation; 2) Selecting approaches and methods appropriate to situation dynamics; 3) Communicating with stakeholders and engaging them in the evaluation design process.#methods #Systems-thinking #Cynefinframework #evaluationdesign
