Managing Complex Organizations in a Complex World

Leadership in Rapidly Changing Business Environments:
Learning & Adapting in Time

NECSI Executive Education Programs

Dates: Feb. 10-11, 2005
Location: Cambridge, MA

Yaneer Bar-Yam: NECSI
Peter Senge: Society for Organizational Learning
and MIT Sloan School of Management
John Sterman: MIT Sloan School of Management

This is a two day practical experience on working
with chaos and complexity - in the global economy, in
national markets, in business to business
interactions and within the organization itself. We
will use new insights and concepts from the field of
complex systems to discuss innovative ways to survive

The 23rd International Conference of the System Dynamics Society

Dates: July 17-21, 2005
Location: Boston, MA

System Dynamics Group, Massachusetts Institute of Technology
Sloan School of Management, Cambridge, Massachusetts USA

The conference program will consist of plenary, parallel,
poster and workshop sessions demonstrating the state of
the art in the theory and application of system dynamics.
The conference schedule will provide time for relaxed social
and professional interaction. The conference will bring
together diverse perspectives on the application of system
dynamics to important issues in the theory of complex dynamic
systems and the practical use of these tools to address
critical real-world challenges. More than 500 people working in
system dynamics and systems thinking will participate.
Presentations by practitioners and world leaders in the
field will cover a wide variety of topics.

New Book: Making Things Work

Making Things Work: Solving Complex Problems in a Complex World
by Y. Bar-Yam (paperback edition)

Today, as individuals and as a society, we are faced
with highly complex challenges. When we don't solve
them correctly they rapidly become crises. This book
explains how we can use complex systems research to
solve complex problems in: healthcare, education,
military conflict, ethnic violence and terrorism,
and international development.

Pre-publication discounted price available until
October 31, 2004.

Nature Paper

E. M. Rauch and Y. Bar-Yam, Theory predicts the
uneven distribution of genetic diversity within
species, Nature 431, pp. 449-452, Sept. 23, 2004.

We studied genealogical trees and discovered that
they have quite general properties that imply
a population will have small groups that are very
distinct from all the rest. These small groups are
like diversity hotspots that we have been trying to
protect in conservation efforts. Since we need to
protect biodiversity to ensure species survival,
we should identify these small groups and protect
them from going extinct.

PNAS Papers

J. K. Werfel and Y. Bar-Yam, The evolution of
reproductive restraint through social communication,
PNAS 101, pp. 11019-11024, 2004.

We examine the evolution of reproductive restraint through
social communication and show that selfish individuals
introduced to an altruistic population end up being driven
to extinction.

For more information:
Y. Bar-Yam and I. R. Epstein: Response of complex networks
to stimuli, PNAS 101, 4341-5, 2004

We challenge the conventional view that robustness is always
desirable in complex systems, describing how controlled
sensitivity and robustness are both needed for a system
to effectively react and adapt to environmental change.
We relate effective response to the structure of random
and scale-free networks.

Call for Book Proposals

The NECSI book series on Complexity published by
Perseus Books Groups is expanding. We welcome book
proposals on topics in complex systems research.
Fundamental studies as well as applications to
specific disciplines or across disciplines are
relevant. Both single author and edited volumes are
of interest. Book proposals should be sent to Please include a half-page to a
page description of the book topic, a statement about
the intended audience, format (single author, edited
volume) and expected length, and tentative outline.

Traveling Seminars

Due to the growing interest in complex systems, we
are offering one-day seminars at universities and
organizations across the United States and Canada.
These seminars provide an opportunity to introduce
basic complex systems concepts and to explore the
scope this field provides for research and
applications. Perhaps the most important part of the
program is the opportunity for participants to
discuss areas of specific interest to them and ask
questions about particular applications.

For examples of past seminars:
