Evaluation, Ahead of Print.
The Full Country Evaluations were Gavi-funded real-time evaluations of immunisation programmes in Bangladesh, Mozambique, Uganda and Zambia, from 2013 to 2016. The evaluations focused on providing evidence for improvement of immunisation delivery in these countries and spanned all phases of Gavi support. The process evaluation approach of the evaluations utilised mixed methods to track progress against defined theories-of-change and related milestones during the various stages of implementation of the Gavi support streams. This article highlights complexities of this type of real-time evaluation and shares lessons learnt on conducting such evaluation from the Zambian experience. Real-time process evaluation is a complex evaluation methodology that requires sensitivity to the context of the evaluation, catering for various information needs of stakeholders, and establishment of mutually beneficial relationships between programme implementers and evaluators. When used appropriately, it can be an effective means of informing programme decisions and aiding programme improvement for both donors and local implementers.
