This report is a review of advocacy within the MSF movement from 2010-2015. Commissioned by the core ExCom, the aim of this review was to explore the effectiveness of MSF advocacy and produce recommendations to improve its approach, coordination and organization in support to operations within the movement. Two external evaluation consultants, Glenn O’Neil and Liesbeth Schockaert, conducted the review with the support of Nirupama Sarma who carried out a complementary review of the Access Campaign (AC). Interviews were conducted with 116 MSF staff from all Operational Centres (OCs), the International Office (IO) and field missions. Visits were carried out to Central African Republic (CAR), the Democratic Republic of the Congo (DRC), Greece, Italy, Jordan and Lebanon. Feedback was also collected from 114 MSF staff through an online survey.
