This paper discusses five strategies to deal with five types of errors in Qualitative Comparative Analysis (QCA):
condition errors, systematic errors, random errors, calibration errors, and deviant case errors. These strategies are
the comparative inspection of complex, intermediary, and parsimonious solutions; the use of an adjustment factor, the
use of probabilistic criteria, the test of the robustness of calibration parameters, and the use of a frequency threshold
for observed combinations of conditions. The strategies are systematically reviewed, assessed, and evaluated as
regards their applicability, advantages, limitations, and complementarities.
