    Use of Data

    Evaluating impact - applying new sources of data

    The availability of information and data is developing at a rapid pace thanks to digitalisation. The quantity and variety of different data formats and sources can be incorporated into ex-post evaluations using modern technology, analysis tools and software and thus evaluation findings can be methodically substantiated. Such information is increasingly being made available free of charge, quickly and indefinitely for almost all sectors and subject areas through open-source portals and general digitalisation.

    With the use of secondary data and new data sources - such as satellite data - quantitative statements on impacts and sustainability can be made. Such data sources can be very useful to supplement missing or inconsistent data during and after project implementation. Especially in fragile contexts and where travel is restricted, these approaches are of great importance in the context of remote evaluations. In general, the use of secondary data sources and analysis methods increases the information content and robustness of evaluation findings.

    Furthermore, the following examples show how the impact of projects can be plausibilised on a sound basis through the use of data.
