we at rational use my notation on some projects, and we have a number
of customers who also use the notation.

the largest project it's been used on is one by bofors in
sweden, for a large (appx 2 million LOC) software system for shipboard command
and control. the interesting aspect of this system is the issues of reuse...
bofors has reused their designs across 5 ships, plus a ground based system.

we  also have a large mis project that has used early parts of my notation.

also the european hood method is somewhat based upon my early oo work, and
that method is in use in a number of projects, including the european
space station.

there are a myriad of other smaller projects using my notation (some telecom
switching system, etc). in fact, much of what iws in my notation is based upon
use in real projects over the past 5-7 years.

not surprisingly, we and others are working on tools to support this notation,
whic provides an alternative to the current case scene. the key for us  is to add rich enough semantics to the tool, so that it is more than just
a pretty picture drawing tool. this means we must deal with
issues of scale, configuration management and version control, and
incrmental changes to designs that preserve the semantic consistency of the whole design.
