of scientific rigor. Why?
development, we almost never build the same thing twice under the same conditions. Add to that the fact that there are no accepted standards of measurement for productivity and defects and you see how intractable the problem can be. Still, a number of studies have been done that provide a significant amount of support to the claim that Ada improves productivity and reduces defects. Your humble narrator was charged with measuring both of these phenomena in a prior job position. We built electronic controls for jet and rocket engines. The team of developers were highly experienced, stable and versed in a variety of programming languages. Ada was introduced as a new language for new projects and the team had to learn & use it for developing embedded systems. Productivity and defect measurement over several years of development indicated that productivity approximately doubled and defects were reduced by a factor of four compared to projects using a variety of other languages.
