Abstract
A standard architectural project comprises multiple interfaces among individual modules of information, components, systems, or players. Each society possesses its own history and background that derives a unique pattern of modules and interfaces. In 2005, Prof. Tomonari Yashiro and Prof. Satoshi Yoshida identified the antagonistic concept of design tendency between modularity and integration. Players from different countries tend to manage projects on different levels of modularity or integration, and create unique work system structures for each. The effects of the difference between modularity and integration were identified, but the mechanism was not demonstrated in visualized or quantified models. This research identifies the United States as the most oriented to modularity and Japan as the country most oriented to integration. The Two countries were the focus of analyses to demonstrate the effect of using the task structure matrix (TSM). The TSM analysis model is a method to visualize and quantify the module pattern and relationship by recording the dependencies of all the elements. This research sought to verify the different pattern of regional modularity between the United States and Japan, as well as offer a quantified understanding to help transnational project players identify the critical paths that are potentially omitted from a project. Keywords: modularity; integration; task dependency; design structure matrix; design information 1. Introduction Configuration Based on the Development of Globalization has been widely infiltrating every Architectural Elements", the authors, Prof. Tomonari aspect of our lives, and even the building construction Yashiro and Prof. Satoshi Yoshida noted the industry is not immune to this trend. When multiple antagonistic differences in design methods between professional players engage in a transnational modularity and integration. They also observed how project with different construction knowledge and the different orientations of integration and modularity backgrounds, the project usually leads to unpredicted would shape the final outcome of artifacts among failure caused by inappropriate management of conflict different cultures. However, this observation was among the players. Although a large amount of research seeking a further quantitative study for verification. has been dedicated to differences among cultures, little To model the process of project execution affected is known about how the mechanism of differing local by concepts of modularity or integration, this research design philosophies and convention could affect the adapted the approach used in "Design Rules, Vol. 1: The outcome of architectural collaborations.
