That has been _exactly_ one of my positions as an INS (IRS)
practitioner! Who exactly are you addressing your comments to? BM,
JY, or DH? The other problem, as pointed out, has been that there
was software re-use without a correct analysis of its suitability
by problem domain experts. A system requirements review with the
involvement of the right problem domain experts _could_ have
determined by analysis whether the Ariane 4 IRS software should
have been reused as is. The failsafe for this review _should_ have
been proper simulation testing as you describe.
