A Methodology for Operationalizing Enterprise IT Architecture and Evaluating Its Modifiability

By: Robert Lagerström, Alan MacCormack, David Dreyfus and Carliss Y. Baldwin

Recent contributions to information systems theory suggest that the primary role of a firm’s information technology (IT) architecture is to facilitate, and therefore ensure the continued alignment of a firm’s IT investments with a constantly changing business... View Details

Design Rules, Volume 2: How Technology Shapes Organizations: Chapter 6 The Value Structure of Technologies, Part 1: Mapping Functional Relationships

Organizations are formed in a free economy because a person or group perceives value in carrying out a technical recipe that is beyond the capacity of a single person. Technology specifies what must be done, what resources must be assembled, what actions taken, and... View Details

Design Rules, Volume 2: How Technology Shapes Organizations: Chapter 14 Introducing Open Platforms and Ecosystems

The purpose of this chapter is to lay the groundwork for a comprehensive theoretical investigation of open platform systems. To do this, we must first recognize that, although there is a strong family resemblance among all platform systems, there are different types of... View Details

The Mirroring Hypothesis: Theory, Evidence, and Exceptions

By: Lyra J. Colfer and Carliss Y. Baldwin

The mirroring hypothesis predicts that organizational ties within a project, firm, or group of firms (e.g., communication, collocation, employment) will correspond to the technical dependencies in the work being performed. This article presents a unified picture of... View Details

Modularity and Intellectual Property Protection

By: Carliss Y. Baldwin and Joachim Henkel

Modularity is a means of partitioning technical knowledge about a product or process. When state-sanctioned intellectual property (IP) rights are ineffective or costly to enforce, modularity can be used to hide information and thus protect IP. We investigate the impact... View Details
