Most NGOs are not set up to rigorously evaluate the bulk of their work. Moreover, many in the sector continue to believe that capturing and tracking data on impact/outcome indicators from only the intervention group is sufficient to understand and demonstrate impact. A number of NGOs have even turned to global outcome indicator tracking as a way of responding to the effectiveness challenge. Unfortunately, this strategy is doomed from the start, given that there are typically a myriad of factors that affect outcome level change.

Oxfam GB, however, is pursuing an alternative way of operationalising global indicators. Closing and sufficiently mature projects are being randomly selected each year among six indicator categories and then evaluated, including the extent each has promoted change in relation to a particular global outcome indicator. The approach taken differs depending on the nature of the project. Community-based interventions, for instance, are being evaluated by comparing data collected from both intervention and comparison populations, coupled with the application of statistical methods to control for observable differences between them.
