Constructing an Outcomes Hierarchy
Evaluation tells us how effective the program has been, identifies areas for modification, generates knowledge or understanding and is a critical element of accountability to the project's stakeholders or investors. It is most effective when it is built into the program from the beginning rather than an afterthought taken up at the end. Evaluation is a process not a product. It can be used to:
Integrate into all stages of program: designing, monitoring and reflecting on success
Adaptively manage the project (formative)
Communicate/report, discuss, theorise, redesign (summative).
