Conference: Analysing the efficiency of development interventions

Are the costs of an intervention proportionate to the outcomes and impact of that intervention?

Share this event

Are the costs of an intervention proportionate to the outcomes and impact of that intervention? That is the key question the Efficiency Lab has been dealing with over the past one-and-a-half years. This lab was established, together with 15 members of Partos, since it was found that in development projects the efficiency question is often not addressed adequately. Well now, the work of the Efficiency Lab is coming to an end and we have some important lessons to share. Therefore, we organise a conference on efficiency to present our findings, the lessons learned and we will look into the consequences that lessons learned might have for the evaluation of the strategic partnerships.


  • 9.30 Welcome & Registration
  • 10.00 Opening
  • 10.30 Pilot Woord & Daad – They conducted a cost-benefit analysis of a value chain development project in the cashew sector in Benin and Burkina Faso, in which (smallholder) farmers, processors and service providers are enabled to increase productivity and efficiency in a collaborative way. The CBA analysis provided insights into the benefits for society and for each of the target groups.
  • 10.50 Pilot Aflatoun – This organisation applied the method of cost-effectiveness analysis of two different approaches to educate young out-of-school mothers who are excluded from the public secondary school system. The findings were used to advise the Tanzanian government and to scale up one of the two approaches.
  • 11.10 Break
  • 11.30 Pilot Simavi – Simavi and its partners, SEBAC and KIDS, have chosen the follow-the-money approach to improve the efficiency of interventions to improve the health and the wellbeing of pregnant women and young mothers during the implementation of the programme. In the evaluation stage, they will use a cost-utility Analysis to relate benefits, in terms of health and well-being, to costs.
  • 11.50 Pilot War Child – This pilot started with an attempt to conduct an efficiency analysis of a proposal for the community-based peacebuilding project in Jonglei, South Sudan. For various reasons, this turned out to be too difficult. Subsequently, two projects in Bogota, Colombia were selected. Both projects target young people who run the risks of being recruited by violent gangs. A partial cost-effectiveness analysis was used to find out which of the two approaches generated most results compared to the costs of the project.
  • 12.10 Reflection
  • 12.30 Lunch Break
  • 13.30 Presentation Markus Palenberg and Pol de Greve on addressing the efficiency question in Lobby & Advocacy interventions
  • 14.00 Discussion on implications for the evaluation of the strategic partnerships
  • 15.00 Closing
