ADE and DPA have created WIND-MEAL, a portfolio of services aimed to build and improve Monitoring, Learning, Accountability and Learning (MEAL) systems, with a focus on accountability (A) up to impact, and on learning perspectives (L) to generate meaningful, up-to-date knowledge to support better decision-making. Based on our experience and values, ADE and DPA develop MEAL systems that are participative, relevant, reliable, realistic, agile, and impact-oriented.
