Some work on this very topic has been going on at Boeing for the
last 18 months or so. Our work has lead us to much the same
conclusions as Shlaer/Mellor, and that is that a combination of
Data/Information modeling, Behavior/state modeling, and Process/
function modeling (with a few structural rules thrown in) can be
used very sucessfuly to not only model system requirements specs
in an object oriented fashion, but also helps tremendously to
identify the objects and classes in a given problem domain. Both
Shlaer/Mellor (AKA Project Technology) and we published papers
in the proceedings of the last Structured Development Forum. (You
may be able to get copies of the proceedings through Ted Michaels,
Lawrence Livermore National Labs, PO Box 808, L-308, Livermore, Ca
94550.

We also published our paper in the proceedings of the upcoming
Ada-Expo (9 thru 11-Oct, Anaheim, Ca), and my co-worker on this
project will present the paper in session 12 (2:00 to 3:30pm,
Tuesday, October 11).

We have a few pilot projects here at Boeing that are using the
method (on some significant applications) with great success. We
hope to publish the results of these pilot projects at upcoming
conferences. Project Technology (Shlaer/Mellor) have consulted on
several _major_ projects using the method and have been quite
successful.

Several other people are also working on object oriented analysis,
but have come to substantially different conclusions. (Dave Bulman,
Pragmatics, Inc. PO Box 3020, Waikoloa, Hi, 96743, Tel (808)883-9011;
Seidewitz and Stark at Nasa-Goddard, no address available, Ed Berard 
at EVB Software Engineering, 5320 Spectrum Drive, Frederick, Md 21701,
Tel (301) 695-6960.)

The field of object oriented analysis is quite new, that accounts for
the lack of published material. But expect a lot of press in the future
(Who? _ME_? Biased? Nahhhhhhh :-).

Shlaer/Mellor would probably send you a copy of their paper (it covers
much more of the method than their book). If you have trouble getting
SDF or Ada-Expo proceedings, I can send copies of our paper to
interested people. My UUCP address is:
