Mark Oldenbeuving – Principal Expert, Monitoring, Evaluation and Learning

Mark is a Principal Expert at Integrity, based in London. His work focuses on the design, monitoring and evaluation of international development projects. He is committed to helping programme teams engage with the complexity of the problems they’re trying to solve. He is an experienced facilitator of Theory of Change workshops to aid the design, delivery and evaluation of international development programmes.

Mark has been a driving force in the design and application of a new approach for programme theory development: the Actor-based Change Framework. This pioneering approach, which was published in the American Journal of Evaluation, marks a significant contribution to the field of programme design and evaluation. Mark co-presented on the ABC Framework at programme at the UK Evaluation Society Conference in London and the American Evaluation Association conference in Cleveland.

Before joining Integrity, Mark worked at Palladium as part of the Research, Monitoring and Evaluation team, and later the Design and Innovation team. While there, he was involved in the Empowerment, Voice & Accountability for Better Health & Nutrition (EVA-BHN) programme. Mark conceptualised and constructed a comprehensive programme theory and monitoring, evaluation and learning system designed to help the programme with data-driven analysis of the complex system it engages in.

He holds an MSc in Development Management from the London School of Economics and an MSc in Political Science from the University of Amsterdam.
