- Actually the long term cost effectiveness of Ada and the Mandate will always
- be unknown for the following reasons:
-
- 1) As the GAO reported a few years ago, there is no systematic
- collection of comprehensive cost data for Ada projects inside
- the DoD, a conclusion the DoD concurred with, and to date has
- done little to address. Nor is there collection of background
- socioeconomic data (such as processor throughput and desktop
- CPU power) that has to be factored out of the Ada cost data.
-
- 2) There are no decent microeconomic models of defense software
- development to use as a basis for analyzing the data collected.
- In fact, data should not be collected until there is such a
- model, otherwise you don't know what variables to measure.
- As there is, and has been, no DoD interest in such models
- (and I do not consider any modified form of COCOMO a suitable
- basis for a microeconomic model, which some have argued),
- the DoD is in the dark, except for ancedotal evidence.
-
- 3) There are no groups independent of the DoD who know enough
- about economics and defense software development to perform
- a valid assessment of this question. The Mosemann studies
- are evidence of the crap you get when the DoD asks one of
- its own to say how well the DoD is doing.
-
- This is not to say that I don't believe that for some projects, Ada is
- very cost effective. I have seen a few private sector projects use Ada
- very cost effectively. Rather, I do not think anyone will be able to
- specifically prove that the Ada mandate is cost effective. Not that
- anyone cares, especially when you have outrageous claims like the original
- STARS claim to increase productivity ten-fold. Any goal far enough in
- the future, backed by a few uniforms, will be funded by Congress in under
- a few tens of millions. None of the originals will be around on judgment
- day.
