Information technology projects are particularly prone to failure due to their specific characteristics, making
risk management become one of the critical elements in IT projects management. That is why several authors
have developed risk evaluation methods, some of them based on fuzzy logic. This article proposes a new risk
assessment method based in a combination of fuzzy analytic hierarchy process (FAHP) and fuzzy inference
system (FIS). FIS is used for the integration of the groups of risk factors. These risk factors are the evaluation
criteria of a modified FAHP which minimizes the disadvantages of the classic implementation of FAHP in order
to obtain a more intuitive and easily adjustable model for multicriteria decision analysis with a lower
computational need. The proposed model takes into consideration the different levels of uncertainty, the interrelationship
among groups of risk factors, and the possibility of adding or suppressing options without
losing the consistency with previous evaluations. The new method is especially suitable for the evaluation
of development projects in the area of IT in which multiple interrelated risk factors can be particularly uncertain
and imprecise. To implement the evaluation method, a hierarchy of risk factors was implemented. A
numerical example is presented with data from three actual cases of IT projects, showing the applicability of
the new method, the suitability of the selected taxonomy, and the significance of a few risk factors. Several
future lines of work are proposed.
