Abstract

High-level modeling of complex systems raises rather serious problems in
specifying behavior. This is true both in the Structured Analysis paradigm
(SA) and in the Object-Oriented one (OO). In the latter case, classes
represent dynamically changing collections of concrete objects, and behavioral
modeling must address issues related to their creation and destruction, the
delegation of messages, the modification and maintenance of relationships,
aggregation, inheritance, etc.  All this has to be done so that the models
remain intuitive and well-structured, but are also behaviorally expressive and
rigorous, supporting full executability and dynamic analysis, as well as
automatic synthesis of usable code in languages such as C or C++. The tutorial
will center on statecharts as a possible "engine" for specifying behavior, and
will describe in some detail the work done over the last 15 years on the
language itself, on embedding statecharts within structural models in both the
SA and OO frameworks, and on building support tools.  We will discuss some of
the misconceptions among practitioners and methodologists, as well as some
central challenges for the future.



		 Extreme Programming: People Writing Programs

				  Kent Beck
				   CS Life
				    Zurich

Extreme Programming is a discipline of software development designed to
sustain productivity from small teams of programmers with ordinary skills over
the life of a software system. It operates by encouraging communication among
developers and between developers and clients. Some of XPs distinguishing
features are:

        * Incremental planning- 
          Clients set development priorities based on consequences provided
	  by developers.
        * Design by refactoring- 
	  The system is designed in response to the need to make concrete 
	  tests run.
        * Pair programming- 
	  All production code is written with two developers sitting at one
	  workstation
        * Relentless testing- 
	  Developers write their own unit tests and a separate team writes 
	  functional tests
        * Continuous integration- 
	  The system is built and unit tested several times a day
 
The talk will explore the philosophical basis of XP, describe its most
clearly ridiculous practices, and describe what teams wishing to adopt
XP can do first.

Speakers Biography
------------------

* David Harel:

David Harel is the William Sussman Professor of Mathematics at the Weizmann
Institute of Science in Israel, and as of January 1998 is the Dean of its 
Faculty of Mathematical Sciences. He was Chairman of the Department of Applied
Mathematics and Computer Science from 1989 to 1995. He is also co-founder 
and chief scientist of i-Logix, Inc., Andover, MA, and is an adjunct professor 
at the Open University in Israel. He is the inventor of the language of 
statecharts (which has been integrated into UML).

Harel received his B.Sc. from Bar-Ilan University in 1974, his M.Sc. from
Tel-Aviv University in 1976 and his PhD from the Massachusetts Institute of
Technology in 1978. He has spent two years at IBM's Yorktown Heights research
center, and sabbatical years at Carnegie-Mellon and Cornell Universities.

His research interests are in computability and complexity theory, logics of 
programs, theory of databases, automata theory, visual languages and systems 
engineering, and he has published widely on these topics. In 1994 he gave a
13-lecture exposition of computer science on Israeli radio, and these days 
is presenting a 14-program series on Israeli television in which he hosts 
prominent computer scientists on a variety of topics. He received the Stevens 
Award in Software Development Methods in 1996, ACM's Karlstrom Outstanding 
Educator Award in 1992, the best paper award in the International Conference 
on Software Engineering in 1988, and the 1997 Israeli Prime Minister's Award 
for Software. His book, Algorithmics: The Spirit of Computing (Addison-Wesley, 
1987, 2nd.  edn. 1992) was the Spring 1988 Main Selection of the Macmillan 
Library of Science. He is a Fellow of the ACM and of the IEEE.

* Kent Beck:

Kent Beck hates writing third-person biographies, but here goes. He has
been developing software for a living for 14 years. He has a nasty
compulsion to speak in public and write. This has resulted in more than
50 technical articles and the book The Smalltalk Best Practice Patterns.
He was instrumental in introducing CRC cards and patterns for software 
development. He is proudest of still making his living writing code. He
is spending a year at CS Life working in Smalltalk on a production 
server for life insurance contract management.
