Contextuality Within Activity Systems

by Michael E. Porter and Nicolaj Siggelkow

Abstract

Research on the interactions among activities in firms and the extent to which these interactions help create and sustain competitive advantage has rapidly expanded in recent years. In this research, the two most common approaches have been the complementarity framework, as developed by Milgrom and Roberts (1990), and the NK-model (Kauffman, 1993) for simulation studies. This paper provides an introduction to these approaches, summarizes key results, and points to an aspect of interactions that has not found much attention because neither of the two approaches is well-suited to address it: contextual interactions, i.e., interactions that are influenced by other activity choices made by a firm. We provide a number of examples of contextual interactions drawn from in-depth studies of individual firms and outline suggestions for future research.

As the diffusion of value-based health care efforts accelerates globally, the need for interoperable information technology systems that support value-based care is essential. Such systems are needed to facilitate dramatic improvements in patient outcomes and efficiency and, importantly, to end an era in which health IT has entrenched the status quo, perpetuated silos, and blocked reimbursement reform. A value-enabling IT platform must organize data around conditions and must enable integrated practice units to integrate care both within and across health systems. In addition, the electronic health record should be the sole source of costing information so that accurate costs for every encounter can be tracked, aggregated, shared, and used for improvement. This is the next generation of health care IT.

Since its establishment in 2005, Hamburg’s Martini Klinik had single mindedly focused on prostate cancer care with a commitment to measure long-term health outcomes for every patient. A wholly owned subsidiary of the University Hospital Hamburg, Martini Klinik was a “hospital in a hospital” in close proximity to other medical departments and services. By 2019, Martini Klinik had become the largest prostate cancer treatment program in the world with 8,000 outpatient cases and more than 2,500 surgical cases annually. Patients came from all over Germany and from around the world. A new and expanded facility was under construction to have the capacity to manage more patients with prostate cancer.

In this report, the authors synthesize their views on U.S. competitiveness and unveil the findings of the 2019 HBS surveys on U.S. competitiveness. Specifically, this report—built on the survey findings and eight years of prior research on the competitiveness of the United States—highlights a disturbing pattern: despite a decade of steady economic growth since the Great Recession, America has done remarkably little to address underlying structural weaknesses in the country’s economy and society. The nation has squandered the recovery.
