Terre des Hommes generally implements its funded projects in collaboration with local partner organizations, but also supports the proper execution of the work and the documentation of project success. The results are reviewed and documented on-site. For large projects or specific issues, external evaluations and program analyses complement the in-house impact monitoring conducted by terre des hommes staff. They can bring specialized expertise and fresh perspectives to the work. Evaluations are more rigorous in nature, whereas program analyses are intended to create a systematic overall picture and, above all, to further develop the working method.
