The process of developing a joint theory of change across three global entities: can this help to make their efforts to strengthen capacity for implementation research more effective?

A theory of change is a visual representation of the pathway by which a programme anticipates it will achieve its goal. It usually starts with discussions around the goal and works backwards through outcomes and outputs to activities.We used a theory of change to improve coherence across three research entities at the WHO. Part of the remit of all three entities is to strengthen capacity in low-income and middle-income countries for implementation research.Representatives from the three entities were able to formulate a joint goal for strengthening capacity in implementation research. They identified three pathways by which this could be achieved: (a) conducting implementation research, (b) strengthening implementation research systems and (c) using implementation research for public health priorities.The process of developing the theory of change and the logic framework it created, provided a means to track progress towards the goal and to guide improvements in programmes within their lifetime. The process we used to develop the theory of change and the pathways to achieve the joint goal are adaptable and could be used by other organisations that also aim to strengthen research capacity. This would lead to more coherence, better translation of research findings into decision-making and ultimately improvements in public health.
