Context Médecins Sans Frontières (MSF) is an independent humanitarian organization providing medical aid to victims of man-made or natural disasters, epidemics and endemic diseases. In the MSF Operational Centre Geneva (OCG), the steering and implementation of field programmes is under the responsibility of an Operations Department, which includes direct medical support to field implementation ensuring fundamental medical standards are reached in all projects. The development of technical and/or strategic solutions adapted to complex medical challenges faced in the field, or to fulfill chosen medical ambitions, is under the responsibility of the Medical Department. Collaborative work between these two departments is considered a cornerstone for the organisation to improve the general quality of its projects and the level of care for patients.
