Understanding the Effects of Product Architecture on Technical Communication in Product Development Organizations

Understanding the effects of product architecture on technical communication in product development organizations by Manuel E. Sosa, Steven D. Eppinger, and Craig M. Rowles This paper examines the impact of architectural decisions on the level of defects in a product. We view products as collections of components linked together to work as an integrated whole. Previous work has established modularity (how decoupled a component is from other product components) as a critical determinant of defects, and we confirm its importance. Yet our study also provides empirical evidence for a relation between product quality and cyclicality (the extent to which a component depends on itself via other product components). We find cyclicality to be a determinant of quality that is distinct from, and no less important than, modularity. Extending this main result, we show how the [...]

Factors that Influence Technical Communication in Distributed Product Development: An Empirical Study in the Telecommunications Industry

Factors that influence technical communication in distributed product development : an empirical study in the telecommunications industry by Manuel E. Sosa, Steven D. Eppinger, Michael Pich, David G. McKendrick, and Suzanne K. Stout Understanding the communication process in product development organizations has been recognized as a key element to improve product development performance. It is particularly interesting to study information exchanges in geographically distributed product development teams because of the highly interdependent nature of design organizations. AAdditionally, the use of electronic-based communication media has changed how development teams communicate. By studying the way product development teams use various communication media (face-to-face, telephone, media), we assess how the process of exchanging technical information is influenced by factors such as [...]

Modeling Impacts of Process Architecture on Cost and Schedule Risk in Product Development

Modeling Impacts of Process Architecture on Cost and Schedule Risk in Product Development by Tyson R. Browning and Steven D. Eppinger To gain competitive leverage, firms that design and develop complex products seek to increase the efficiency and predictability of their development processes. Process improvement is facilitated by the development and use of models that account for and illuminate important characteristics of the process. Iteration is a fundamental but often unaddressed feature of product development (PD) processes. Its impact is mediated by the architecture of a process, i.e., its constituent activities and their interactions. This paper integrates several important characteristics of PD processes into a single model, highlighting the effects of varying process architecture. The PD process is modeled as a network of activities that exchange deliverables. Each activity [...]
