Maximising the Quality of Scaling Up Nutrition Plus (MQSUN⁺) provides recommendations on the technical design and delivery model of the United Kingdom’s Department for International Development’s (DFID) country nutrition programmes. Programmatic design typically starts from elaboration of a Business Case to define the available resources (time, expertise and money) and to identify the best evidence-based approaches and mechanisms for maximum impact. MQSUN⁺ also supports the inception phase of programmes, which can include facilitating planning meetings, applying a technical lens to programme activities, supporting partners to recognise clear trajectories towards improved results and reviewing and providing guidance on programme proposals. Other technical assistance areas related to programme support may include Annual Reviews, monitoring programme activities against planned inputs, building technical and functional capacities of implementers and assessing effective programme approaches and activities prior to the development of a new Business Case.
