Overview

Christian Terwiesch is a Professor of Operations and Information Management at The Wharton School of the University of Pennsylvania. He also is a Senior Fellow at Leonard Davis Institute for Health Economics and Co-Director for the Mack Institute for Innovation Management. His research on Operations Management and on R&D and Innovation Management appears in many of the leading academic journals, including Management Science, Operations Research, Marketing Science, and Organization Science. He is also active on various editorial boards for journals including Management Science and Production and Operations Management.

Professor Terwiesch has researched with and consulted for various organizations, including a project on concurrent engineering for BMW, supply chain management for Intel and Medtronic, and product customization for Dell. Most of his current work relates to healthcare and innovation management. In the healthcare space, some of Professor Terwiesch recent projects include the analysis of capacity allocation for cardiac surgery procedures at UCSF and at HUP, the impact of emergency room crowding on hospital capacity and revenues (also at HUP), and the usage of ICU beds in the Children’s Hospital of Philadelphia. In the innovation space, recent projects include the management of the clinical development portfolio at Merck, the development of open innovation systems, and the design of patient centered care processes in the VA hospital system.

Professor Terwiesch is the co-author of Matching Supply with Demand, a widely used text-book in Operations Management. His latest book, Innovation Tournaments, has just appeared last summer. The novel, process-based approach to innovation outlined in the book was featured by BusinessWeek, the Financial Times, and the Sloan Management Review.

  • OPIM611 - Quality and Productivity

    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.

  • OPIM614 - Innovation

    The course is first and foremost an intensive, integrative, project course in which student teams create one or more real businesses. Some businesses spun out of the course and now managed by alumni include Terrapass Inc. and Smatchy Inc. The project experience is and exciting context in which to learn key tools and fundamentals useful in innovation, problem solving, and design. Examples of these tools and fundamentals are: problem definition, identification of opportunities, generating alternatives, selecting among alternatives, principles of data graphics, and managing innovation pipelines. The course requires a commitment of at least 10 hours of work outside of class and comfort working on unstructured, interdisciplinary problems. Students with a strong interest in innovation and entrepreneurship are particularly encouraged to enroll. Please read carefully the syllabus posted on-line before registering for this course.

  • OPIM631 - Operations Management: Quality and Productivity

    This course emphasizes processes. A process is a set of interrelated work activities characterized by specific inputs and value-adding tasks that rpoduce specific outputs. In the first part of the course, we will see examples of a number of processes and learn how to describe a process with a flow diagram. We will also learn to measure key process parameters like capacity and lead time, and to improve a process through approaches like finding and removing bottlenecks or better division of the work among the people involved in the process. The second part of the course focuses on process improvement and will examine some classic ideas in quality management as well as recent ideas about restructuring processes for increased performance.
