    Developing Adaptive Software with the Demeter Method

		  Karl J. Lieberherr
	       Northeastern University, Boston

In today's competitive business environment, companies must be able to
react to market changes quickly. The speed of reaction is often
directly related to how rapidly they can change their software.  For
this purpose, the Demeter Method promotes the development of 
adaptive software.  Adaptive means that the software adapts itself to
a very interesting class of requirements changes.  Adaptive software
is in general more flexible than traditional software.  The ability to
support the development of adaptive software is the feature which
distinguishes the Demeter Method from all other oo methods.

Adaptive software is a natural evolution of oo software since every
object-oriented program is essentially an adaptive program.  Although
object-oriented programs are easier to reuse than programs which are
not written in an object-oriented style, oo programs are still very
rigid and hard to evolve. Experience shows that for most application
domains, object-oriented programs can be made significantly more
general and extensible by expressing them as adaptive programs.

The talk will present the important ideas behind adaptive software and
will outline how adaptive software has been used successfully within a
project at Citibank.

Dear Colleage,

Our January speaker Karl J. Lieberherr is a Professor in the College
of Computer Science at Northeastern University and Director of the
Center for Software Sciences.  His current research interests are in
object-oriented software engineering.  His research group is
developing the Demeter System, consisting of the Method and the Tools,
to facilitate software development by introducing novel high-level
abstractions.  His earlier research interests include design
automation for VLSI (he is the principal designer of the hardware
description language Zeus), analysis of algorithms (he is the
codeveloper of the concept of P-optimal approximation algorithms for
combinatorial optimization problems) and public-key cryptography.
Professor Lieberherr got his Ph.D. from ETH Zurich, Switzerland, he
served on the faculty of Princeton University and ETH Zurich and the
staff of GTE Laboratories, Waltham, Ma. He can be reached at
lieber@ccs.northeastern.EDU.

We will be meeting for dinner at Joyce Chen's restaurant, 390 Rindge
Ave., Cambridge at 6:00 p.m. before the meeting.  If you wish to come,
please call "Sigplan dinner" at Intermetrics (661-1840) as early as
possible so we can make the appropriate dinner reservation.
