Software Systems Architecture Agility

Contemporary business environments are under constant change. Therefore, the software applications supporting the business need to be changed as well, and at the same pace. However, many companies experience that it is becoming more difficult and expensive to carry applications architecture changes through. One reason is that during the past decades the number of applications has constantly been increasing and these applications have become more dependent on one another. Due to the growing number of applications and their dependencies, management of software applications has become a complex task. In order to achieve effective and efficient management of the enterprise application architecture it is essential to be able to analyze and visualize the modularity of the architecture and the degree of coupling between its applications.

This project is a collaboration project between associate professor Robert Lagerström  and Harvard Business School  professors Carliss Baldwin  and Alan MacCormack  . It includes collaboration with Swedish, German, and American companies.

Particular interest and industrial testing has been done with Ericsson in Sweden. Several bachelor and master thesis projects have been conducted within this project.

Several publications have come out of this project:

Robert Lagerström, Alan MacCormack, David Dreyfus, and Carliss Y. Baldwin, “A Methodology for Operationalizing Enterprise IT Architecture and its Modifiability”, accepted for publication in Complex Systems Informatics and Modeling Quarterly (CSIMQ), 2019.
