{Excerpt} Feedback is a circular causal process whereby some portion of a system’s output is returned to the input to control the dynamic behavior of the system. In organizations, feedback is the process of sharing observations, concerns, and suggestions to improve performance. In work that seeks to address the increasingly complex challenges of development, often with limited resources, feedback is essential to maximize development impact. Knowledge Solutions: Monthly Progress Notes asserts that the essential first steps of feedback are the processes of monitoring and evaluation. They identify challenges, recognize common constraints, and note that the submission of monthly progress notes on activities and accomplishments is too infrequently provided in the scope of projects and programs. There are opportunities too for more systematic capture and storage of feedback from executing agencies on the effectiveness of assistance in capacity development, prior to knowledge sharing and learning. Capacity development is the process whereby people, organizations, and society as awhole unleash, strengthen, create, adapt, and maintain capacity over time. In 2005, the Paris Declaration on Aid Effectiveness called for capacity development to be an explicit objective of the national development and poverty reduction strategies of partner countries. Bilateral and multilateral agencies, among others, have responded by elevating capacity development in their operations, and given attention to factors that drive success and factors that deter from it.
