I'm aware of 2 real-world studies, in 2 different domains, of real projects, done both in C and Ada, with good metrics, that show that Ada reaches deployment in half the time/cost of C. As a result, I see no evidence to support claims that C-like languages have better time-to-market characteristics than Ada. These same studies show Ada has a factor of 4 fewer post-deployment errors, and a factor of 10 less time/cost to correct an error. Note to MDC: All other things are not equal, but that was true of these projects as well, and Ada still came out with a factor of 2 advantage on time to deployment. -- Jeff Carter "Brave Sir Robin ran away."
