ALNAP adapted an action learning approach for use in frontline humanitarian contexts. Action learning is a practical approach to learning-by-doing that only requires a limited time and resource investment. It focuses on both reflection and practical solutions, by encouraging actions that can have an immediate impact on projects as they are implemented and by supporting ongoing sharing of knowledge with peers. Action learning has been used successfully in several contexts, including the private sector, social services, health organizations, domestic charities, and international development.
