As the fundamental model for managing inventory under demand uncertainty, the newsvendor model has received significant research attention, but behavioral issues—the focus of this paper—have been less well studied. Nils Rudi and David Drake demonstrate how different aspects of the newsvendor model, a rather complex managerial decision setting, result in a combination of behavioral deviations from the normative solution prescribed within existing literature. The results can help managers prioritize order quantity improvements based on product margins and the degree of demand feedback available in the setting that they operate in.

Every manufacturing process leaves waste, but Assistant Professor Deishin Lee believes much of this left-behind material can be put to productive—and profitable—use.
Why might firms make operational decisions that purposefully do not maximize expected profits? This model looks at the question by developing scenarios using the example of inventory management in the face of an external investor. The research was conducted by Vishal Gaur of Cornell University, Richard Lai of the University of Pennsylvania, and Ananth Raman and William Schmidt of Harvard Business School.
Scholars have intensely studied the similarities and differences between organizations that are decentralized in their decision making versus those favoring more command-and-control central authority. What leads to a firm following a decentralized approach, and can that approach be predicted? Professor Kristina McElheran advances previous, largely theoretical, research on this subject to explore in the real world the economic determinants affecting how IT purchasing authority in 3,000 multi-establishment companies was allocated between central headquarters and outlying establishments.
In practice, many large firms are now realizing the importance of humanism in corporate management. But in academia, much of management theory is still stuck on the ideas of early industrialization - focusing solely on the idea that the only real value is financial value. In this paper, Rosabeth Moss Kanter discusses how social logic guides the practices of many high-performing companies. Kanter suggests that such successful practices should provoke the creation of new economic theory, which will in turn provoke other firms to take note. She puts forth several propositions to make the case.

"Supply learning" is the process by which customers predict a company's ability to fulfill product orders in the future using information about how well the company fulfilled orders in the past. A new paper investigates how and whether a customer's assumptions about future supplier performance will affect the likelihood that the customer will order from that supplier in the future. Research, based on data from apparel manufacturer Hugo Boss, was conducted by Nathan Craig and Ananth Raman of Harvard Business School, and Nicole DeHoratius of the University of Portland.
Boredom and fatigue often hamper the productivity of workers whose jobs consist of repeating the same tasks. This paper explores ways in which companies can combat this problem, introducing the idea of the "restart effect" - a deliberate disruption that kindles productivity. Research, which focused on a loan-application processing line at a Japanese bank, was conducted by HBS professor Francesca Gino and Kenan-Flagler Business School assistant professor Bradley R. Staats.
To improve patient safety, hospitals hope their staff will use error-reporting systems. Question is, how can managers encourage employees to take the next step and ensure their constructive use? New research by Julia Adler-Milstein, Sara J. Singer, and HBS professor Michael W. Toffel.
How can front-line workers be encouraged to speak up when they know how to improve an organization's operation processes? This question is particularly urgent in the US health- care industry, where problems occur often and consequences range from minor inconveniences to serious patient harm. In this paper, HBS doctoral student Julia Adler-Milstein, Harvard School of Public Health professor Sara Singer, and HBS professor Michael W. Toffel examine the effectiveness of organizational information campaigns and managerial role modeling in encouraging hospital staff to speak up when they encounter operational problems and, when speaking up, to propose solutions to hospital management. The researchers find that both mechanisms can lead employees to report problems and propose solutions, and that information campaigns are particularly effective in departments whose managers are less engaged in problem solving.

Operational failures occur within organizations across all industries, with consequences ranging from minor inconveniences to major catastrophes. How can managers encourage frontline workers to solve problems in response to operational failures? In the health-care industry, the setting for this study, operational failures occur often, and some are reported to voluntary incident reporting systems that are meant to help organizations learn from experience. Using data on nearly 7,500 reported incidents from a single hospital, the researchers found that problem-solving in response to operational failures is influenced by both the risk posed by the incident and the extent to which management demonstrates a commitment to problem-solving. Findings can be used by organizations to increase the contribution of incident reporting systems to operational performance improvement.
What is the optimal scope of operations for firms? This question has particular relevance for the US hospital industry, because understanding the effects of focus and spillovers might help hospitals determine how they should balance focusing in a single clinical area with building expertise in related areas. While some scholars argue that narrowing an organization's set of activities improves its operational efficiency, others have noted that seemingly unfocused operations perform at a high level and that a broader range of activities may in fact increase firm value. This study by HBS doctoral student Jonathan Clark and professor Robert Huckman highlights the potential role of spillovers—specifically complementary spillovers—in generating benefits from focus at the operating unit level.

Products are often said to "mirror" the architectures of the organization from which they come. Is there really a link between a product's architecture and the characteristics of the organization behind it? The coauthors of this working paper chose to analyze software products because of a unique opportunity to examine two different organizational modes for development, comparing open-source with proprietary "closed-source" software. The results have important implications for development organizations given the recent trend toward "open" approaches to innovation and the increased use of partnering in research and development projects.
Can lean production methods be used in service industries? How can operations be used to competitive advantage? These are several of the questions answered in this month's Sharpening Your Skills on the topic of operations management.

Toyota and other top manufacturing companies have embraced, improved, and profited by lean production methods. But the payoffs have not been nearly as dramatic for service industries applying lean principles. HBS professor David Upton and doctoral student Bradley Staats look at the experience of Indian software services provider Wipro for answers.
For the last 30 years economists have used the concepts of "transaction," "transaction cost," and "contract" to illuminate a wide range of phenomena, including vertical integration; the design of employment, debt, and equity contracts; and the structure of industries. These concepts are now deeply embedded in the fields of economics, sociology, business, and law. Theories explain how to choose between different forms of transactional governance. But why does a transaction occur where it does? Without this answer, the forces driving the location of transactions in a system of production remain largely unexplored. This paper explains the location of transactions (and contracts) in a system of production. It also presents a theory of technological change that predicts changes in the location of transactions and therefore in the structure of industries.
Research in psychology over the past several decades teaches us that behavioral biases and cognitive limits are not just "noise"; they systematically affect (and often distort) people's judgment and decision making. Despite such advances, however, most scholarly research in operations management still assumes that agents—be they decision makers, problem solvers, implementers, workers, or customers—either are fully rational or can be induced to behave rationally, usually with economic incentives. This paper builds on earlier studies to explore the theoretical and practical implications of incorporating behavioral and cognitive factors into operations management models. It then points to fruitful areas for future research.
Designers have long recognized the value of modularity. But because design principles are informal, successful application depends on the designers' intuition and experience. Intuition and experience, however, do not prevent a company such as Microsoft from constantly grappling with unanticipated challenges and delays in bringing software to market. Clearly, designers need a formal theory and models of modularity and software evolution that capture the essence of important but informal design principles and offer ways to describe, predict, and resolve issues. This paper evaluates the applicability of model and theory to real-world, large-scale software designs by studying the evolution of two complex software platforms through the lens of design structure matrices (DSMs) and the design rule theory advanced by Kim Clark and Carliss Baldwin.
The interdisciplinary research of economist Kim Clark, former dean of Harvard Business School and now President of Brigham Young University-Idaho, occupies a unique place in management scholarship for three reasons. First, he tended to focus on little known and under-appreciated management groups such as manufacturing managers, product development managers, and product and process architects. Thus, he directly positioned himself outside the "traditional" management disciplines of strategy, finance, marketing, and organizational behavior. Second, he swam against the academic tide by recognizing the power of comparative and longitudinal field studies. Third, he sought frameworks beyond his own field in design theory, the engineering sciences, and finance. This paper reviews his research contributions over almost thirty years.
Scholars have long been interested in the impact of information technology on the organization of work. As Andrew McAfee and colleagues argue in this study, the appropriate governance mechanism for an IT-facilitated collaboration depends on the type of IT being deployed: When an enterprise technology is required, so is an electronic hierarchy. The paper explores the issue of relationship specificity of IT assets, proposes a categorization of information technologies based on their levels of relationship specificity, and uses data from more than forty Italian industrial districts to test three hypotheses around governance of interfirm IT. These districts typically have close ties, both horizontal and vertical, and have historically worked in close collaboration with each other.

Organizations often commit to more product development projects than they can handle. And while people do not always behave rationally, most research on operations management still assumes they do. This paper explores theoretical and practical ways to study the effects of behavior and cognition on operations.

Activity-based costing (ABC) has become popular in business writing and management circles. (An example of an activity would be process customer complaints.) However, calculating baselines for activities, developing the model, and retesting the model once it is implemented is time-consuming and costly. Kaplan and Anderson developed improvements in the process through what they call time-driven ABC. Time-driven ABC decreases the amount of data needed, and only requires estimates of two things: (1) the practical capacity of committed resources and their cost, and (2) unit times for performing transactional activities.

How can one production operation be both rigidly scripted and enormously flexible? In this summary of an article from the Harvard Business Review, HBS Professors H. Kent Bowen and Steven Spear disclose the secret to Toyota's production success. The company's operations can be seen as a continuous series of controlled experiments: whenever Toyota defines a specification, it is establishing a hypothesis that is then tested through action. The workers, who have internalized this scientific-method approach, are stimulated to respond to problems as they appear; using data from the strictly defined experiment, they are able to adapt fluidly to changing circumstances.
