In summary, based on the results of currently available empirical data and feature analysis comparisons, a conclusion that Ada is superior, with respect to availability/reliability and a lower incidence of defects, appears warranted. The evidence is not strong enough to assert Ada's superiority in the cost area. However, there is some positive evidence in the cost area, and when it is combined with the anecdotal conclusions favoring Ada (described in "Anecdotal Experience from Projects" in Chapter 2) and the lack of solid evidence indicating less expensive custom software development in other languages, a case can be made that using Ada provides cost savings in building custom software, particularly for real-time, high-assurance warfighting applications.
