The high percentage of IS/IT projects that have not met their intended business objectives, i.e. that have “failed”, has continued to be a major concern for organisations since the 1970s. Such projects were either abandoned, significantly redirected, or even worse, they were “kept alive” in spite of their failure. The cost of funding those projects and the missed opportunities of not benefiting from their intended capabilities can represent a tremendous loss for organisations. This phenomenon has created the need for the development of evaluation methods to measure the effectiveness of IS/IT.
