Open innovation is a powerful framework encompassing the generation, capture, and employment of intellectual property at the firm level. We identify three fundamental challenges for firms in applying the concept of open innovation: finding creative ways to exploit internal innovation,...

We study competitive interaction between profit-maximizing firms thatsell software and complementary goods or services. In addition totactical price competition, we allow firms to compete through businessmodel reconfigurations. We consider three business models: theproprietary model (where all...

Empirical research on Free/Libre/Open Source Software (FLOSS) has shown that developers tend to cluster around two main roles: "core" contributors differ from "peripheral" developers in terms of a larger number of responsibilities and a higher productivity pattern. A further, cross-cutting...

We consider software developers who can either work on an open sourceproject or on a closed source project. The former provides a publiclyavailable signal about their talent, whereas the latter provides asignal only observed by their employer. We show that a talented employeemay initially prefer...

Defect-occurrence projection is necessary for the development of methods to mitigate the risks of software defect occurrences. In this paper, we examine user-reported software defect-occurrence patterns across twenty-two releases of four widely-deployed, business-critical, production, software...

Open source software systems are critical infrastructure for many applications; however, little has been precisely measured about their quality. Forecasting the field defect-occurrence rate over the entire lifespan of a release before deployment for open source software systems may enable...

A new method for making software is stealthily gaining ground in the computer industry, offering a promise of better, cheaper software and the empowerment of the user. The open source movement could revolutionize the software industry...if it succeeds. Open source means software that you are...

As an emerging innovation paradigm gaining momentum in recent years, the open innovation paradigm is calling for greater theoretical depth and more empirical research. This dissertation proposes that open innovation in the context of open source software sponsorship may be viewed as knowledge...

Test tools have become ubiquitous in the practice of Software Quality Assurance. Every year, many millions of dollars are spent on specialized software to help manage requirements, test cases, or defects—or to automate test execution. But, after purchasing the software, many companies fail to...
