Historical Classics Originally Published by MIT Press


Thanks to the time and expertise of our expert modelers, Len Malczynski (Mindseye Computing, LLC), Donald DeLand, Georgios Papachristos (Eindhoven University Dept. of Innovation Science The Netherlands), and Robert Ward, the System Dynamics Society has updated Growth of a New Product by Ole C. Nord and Resource Acquisition in Corporate Growth by David W. Packer, both originally published by The MIT Press in 1963 and 1964, respectively. This group of expert modelers has updated the original DYNAMO models into modern software (Stella, Vensim, and Studio), as well as digitized the books, and the Society will put these historical classics from the field of System Dynamics back into print. The updated models (copyright © 2023 by System Dynamics Society) run as the original DYNAMO models and you can access these models when purchasing the book or the models can be purchased separately. Both authors, Ole Nord and David Packer, were students of Jay Forrester at MIT, and their works are critical to the study of industrial dynamics, business, and management.

Updated models from these classic historical books in the field!

Growth of a New Product: Effects of Capacity-Acquisition Policies, by Ole C. Nord, is the first in a series of publications on industrial dynamics research, originally published by The MIT Press in 1963. The System Dynamics Society has republished this book and updated the models using modern software (copyright © 2023 by System Dynamics Society). The models are certified to run as the original DYNAMO models. Don’t miss this opportunity to read the original book and access the updated models, which are still very relevant in business today.

This illuminating monograph delves into the dynamic interplay between a firm’s capacity acquisition policies and the growth of its market. Serving as an exemplar of the industrial dynamics approach to managerial challenges, this book provides profound insights into the management of companies, unveiling how managerial policies can significantly impact growth behavior. Growth of a New Product dissects the interactions between information flow, finance, orders, materials, inventory, personnel, and capital equipment within an organization, industry, or national economy, turning abstract theories into tangible strategies. This book is an essential companion for those studying industrial dynamics formally or informally, executives in business, or anyone keen on understanding the intricate machinery that propels business growth.

Learn about corporate growth and access simulation models

Resource Acquisition in Corporate Growth is the second industrial dynamics study published by The MIT Press, originally published in 1964. The System Dynamics Society has updated the models in the book (copyright © 2023 by System Dynamics Society), using modern software (Stella, Vensim, and Studio), and they run as the original DYNAMO models. The Society has republished these classical books and had provided access to the models.

What sets Resource Acquisition in Corporate Growth apart is its focus not only on the ‘what’ and ‘why’ of resource acquisition, but also the ‘how.’ David Packer demystifies the dynamics of resource acquisition, highlighting the significance of successful resource management in an expanding business context. The book offers in-depth insights into managerial delays and efficiencies, the absorption of professional effort, and the role of recruitment in augmenting professional capabilities. It also underscores the role of simulation modeling, offering practical tools to forecast resource needs accurately. Packer makes a compelling case for why businesses must understand these critical dynamics to avoid inefficiencies and maximize growth potential.

In Resource Acquisition, be prepared to uncover strategic pathways to navigate your business successfully through growth phases, fuelled by efficient and effective resource acquisition. It delves into how inventory levels, backlogs of unfilled orders, and other physical conditions can create pressures for expansion or contraction, illustrating these dynamics with tangible case studies and practical examples. David Packer’s work gives insights into the regenerative processes creating growth, the role of managerial policies in these processes, and ways for designing policies that promote desirable performance.

Whether you’re a business professional seeking to enhance your understanding of resource management in a growing firm, or a student of business and management studies or industrial dynamics keen to grasp the intricacies of corporate expansion, this book is a valuable addition to your library.


These classical works in the System Dynamics field are valuable to understanding industrial dynamics. A group of expert volunteer modelers and members of the System Dynamics Society has updated the models in modern software, and they run as the original DYNAMO models did. Now researchers, students, and professionals in the System Dynamics community can access these resources and the insights these historical books and simulation models provide about new product growth, corporate expansion, and capacity-acquisition policies.

Models are explicit representations of the world that allow us to analyze assumptions, relationships, and logic, therefore providing a much better means than our mental models to understand the world. Further, models are amazing visualization tools.

We believe models by others are useful to learn and compare, create dialog, and inspire.
