His latest book, Innovation Tournaments, was published by Harvard Business School Press. The novel, process-based approach to innovation outlined in the book was featured by BusinessWeek, the Financial Times, and the Sloan Management Review and has lead to innovation tournaments in organizations around the world.
Professor Terwiesch has researched with and consulted for various organizations. From small start-ups to Fortune 500 companies, he has helped companies become more innovative, often by implementing innovation tournament events and by helping to restructure their innovation portfolio.
Most of his current work relates to healthcare and innovation management. In the healthcare space, some of Professor Terwiesch recent projects include the design of patient centered care processes in the VA hospital system, the impact of emergency room crowding on hospital revenues and the patient experience at Penn Medicine, and the usage of patient portals and remote patient monitoring.
In addition to his teaching and his research, Professor Terwiesch is experimenting with a new career as a host of a national radio show on Sirius XM 132. Also, after 20 years of Ironman racing, he is trying to become a competitive rower, a transition that unfortunately turns out to be harder than expected.
Suparerk Lekwijit, Christian Terwiesch, David Asch, Kevin Volpp (Under Review), Evaluating the Efficacy of Connected Healthcare: An Empirical Examination of Patient Engagement Systems and Their Impact on Readmission.
Abstract: Connected healthcare is a form of healthcare delivery that connects patients and providers through connected health devices and real-time health information sharing, allowing providers to monitor patient behavior and proactively intervene before an adverse event occurs. Unlike the costs of implementation, the benefits of connected healthcare in improving patient behavior and health outcomes are usually difficult to determine. In this study, we empirically examine the efficacy of a connected health system that aimed to reduce the number of readmissions through improved medication adherence. Specifically, we study 1,000 patients with heart disease who received electronic pill bottles, which tracked medication adherence in real time. Patients who were non-adherent received active social support that involved different types of feedback such as text messaging and phone calls. By integrating data on medication adherence, behavioral interventions, and readmissions, we aim to (1) investigate the efficacy of connected healthcare in promoting medication adherence and to (2) examine the relationship between medication adherence and readmission. Our findings suggest that, unlike non-personalized automated feedback, personalized manual feedback was highly effective in making a non-adherent patient adherent again. Moreover, there existed neither a learning effect nor an alarm fatigue effect as patients received more feedback of the same type. We also find that long-term adherence to statins, which help lower cholesterol, was strongly associated with a reduction in the readmission risk. Lastly, we develop an adherence-based readmission risk-scoring model that is shown to be unbiased and more discriminative than a model that does not include medication adherence.

Lesley Meng, Bob Batt, Christian Terwiesch (Working), The Impact of Facility Layout on Worker Behavior: An Empirical Study of Nurses in the Emergency Department.
Abstract: We study the impact of service facility layout on how service workers organize their tasks. We focus on the hospital emergency department (ED) as a service setting where nurses (servers) have discretion over how they interact with their patients (customers) in a facility that introduces significant heterogeneity in necessary walking distance. We utilize a unique dataset consisting of infrared nurse location tracking data, patient EMR data, bedside call data, and the architectural floor plan, to show that nurses reduce their total walking distance by decreasing the frequency of visits to patient rooms far away. We show that this behavior is consistent with batching their tasks rather than a reduction of tasks. While this behavior reduces necessary nurse walking, it comes at the expense of poorer care quality. We find that patients in rooms farthest away press the nurse call button more frequently, an action that is linked with poor patient satisfaction. These findings show that even in services, facility layout can lead to servers with discretion over task timing using that discretion in ways that help the server but that lead to reduced customer quality.

The Senior Capstone Project is required for all BAS degree students, in lieu of the senior design course. The Capstone Project provides an opportunity for the student to apply the theoretical ideas and tools learned from other courses. The project is usually applied, rather than theoretical, exercise, and should focus on a real world problem related to the career goals of the student. The one-semester project may be completed in either the fall or sprong term of the senior year, and must be done under the supervision of a sponsoring faculty member. To register for this course, the student must submit a detailed proposal, signed by the supervising professor, and the student's faculty advisor, to the Office of Academic Programs two weeks prior to the start of the term.
The word "operations" derives from the Latin "opus," and opus means work. So by definition, operations is about work. This course offers an introduction to operations management: after completing the course, you will be able to use a systematic approach for analyzing and improving your work in health care settings. This will benefit patients, teams of care providers, and staff. The course includes an examination of inefficiencies resulting from the three system inhibitors: waste, variability, and inflexibility. And it provides strategies for engaging in the ongoing process of reducing these negative impacts without sacrificing quality of care. This course offers an introduction to operations management, examining inefficiencies from waste, variability, and inflexibility and providing strategies for engaging in the ongoing process of reducing these negative impacts without sacrificing quality of care. After completing the course, learners will be able to use a systematic approach for analyzing and improving their work in health care settings.

Technology has allowed firms to fundamentally change how they connect with their customers. Rather than having occasional, episodic interactions--where customers realize they have an unmet need and then look for ways to fill it--firms are striving to be continuously connected to their customers, providing services and products as the needs arise, even before customers become aware of them. There is probably no other industry for which this development will be as transformative as in health care delivery. Wearable devices, smart pill bottles, and digestible sensors--all of these technologies, and many more, are associated with the promise of improving the quality of care while also making efficient use of resources. This course explores the impact of connected strategies in general, and in particular the opportunities associated with them in health care delivery.
Matching supply with demand is an enormous challenge for firms: excess supply is too costly, inadequate supply irritates customers. In the course, we will explore how firms can better organize their operations so that they more effectively align their supply with the demand for their products and services. Throughout the course, we illustrate mathematical analysis applied to real operational challenges--we seek rigor and relevance. Our aim is to provide both tactical knowledge and high-level insights needed by general managers and management consultants. We will demonstrate that companies can use (and have used) the principles from this course to significantly enhance their competitiveness.
