Message-ID: List-Id: >the estimated difference in lifecycle cost (i.e. the total delta over >the estimated 30-year life of a particular system) was $45 million >HIGHER if Ada was the development language? I'd very much like to see a reference/citation for this, as it flies in the face of both deeply held religious beliefs and also most of the available data (e.g. Reifer studies, AFATDS preliminary data, etc). dave p.s. I've seen some people come up with higher start-up costs for Ada. (In part due to retraining, learning the language, etc, and in part due to front-loading the life cycle by spending more time doing design.) It's possible that someone took the delta from start-up costs, and applied it into his favorite old-fashioned cost model to obtain linear cost increases.
