The evaluation wheel is a graphic device for comparing evaluands on specific criteria. (Remember that an evaluand is a fancy word for whatever is being evaluated.) It is a versatile tool that can be used in a variety of ways:
- Individuals can use it to indicate strengths and weaknesses of their performance on some task over a period of time.
- As a group exercise it can illuminate differences in perceived strengths and weaknesses of something by the group members. A composite wheel is constructed from wheels completed by individuals.
- As a multi-group exercise it enables comparison of perceived strengths and weaknesses of something as perceived by the different groups.
The graphic is a wheel with intersecting spokes. There may be a few spokes or many spokes. In general each pie wedge in the wheel or each spoke of the wheel is a scale for some factor. The inner tip of the wedge or the center of the spoke is the minimum value. The complete wedge or the point where the spoke intersects the rim of the wheel is the maximum value.
An evaluation wheel can be simple or complex. For a simple example see http://www.trocaire.org/sites/trocaire/files/pdfs/edu/Worksheet3.pdf
For a complex example see http://www.publicprivatedialogue.org/tools/ANNEXES/evaluation_tool/
The attached file shows an evaluation wheel for a participatory evaluation that compares the extent of participation by program staff in various aspects of the evaluation with participation by program participants other than staff.
