Until now, there has been no reliable, commonly accepted method for determi
ning the probability of success of individual technical projects. Over the
past few years, an IRI subcommittee has developed a core set of "anchored s
cales" for determining these probabilities by combining the inputs from mul
tiple individuals in a method that is both move efficient and more reliable
than previous methods. The scales were developed with inputs from a cross-
section of IRI member companies whose goal was to create a common platform
that could be easily modified by individual companies. Consequently, practi
tioners can use these scales as a starting point to customize this fool to
fit their own particular circumstances.
