Dave and Karsten,

  If I am not mistaken, UNIX was designed exactly as a reaction to the
"Big IT Way" of implementing software/operating systems (with 100k
function points, many of which tend to fail in a highly inter-related
fashion).

  In the arena of EHR, both GEHR/OpenEHR and OIO propose a domain-specific
layer (archetypes/forms/workflows etc) aims/claims to make it easier to
build modular applications. Each "application" will provide a limited few
number of "function points". Each "application" can be authored easily by
domain experts without programmer resources (avoiding some of the
associated risks). If any one "application" fails, the problem will be
easy to isolate, locate, and fix - and hopefully affect other applications
in a predictable and limited fashion.
  (Thomas, please feel free to point out my ignorance if I have
mis-characterizing OpenEHR in any way.)

Best regards,

Andrew
