Process-parameter-interface model for design management

Abstract

This paper presents a framework for managing the architecture/engineering/ construction design process. The framework, called the process-parameter- interface (PPI) model, tries to address the design management issues of improved design process scheduling and efficient collaboration. The model comprises three main components - a design parameter vocabulary, in the form of a design dictionary; an interface; and an engine - that help to address these issues. In addition, the model promotes flexibility of design work flow, enables proactive collaboration, is implementable over the Internet, and is information-centric. The paper concludes with a case study for the design of a conference room to illustrate the functioning of the PPI model and the role of its components.
