The paper "CONWIP: a pull alternative to kanban" by Professor Wally Hopp and coauthors, published in The International Journal of Production Research in 1990, presents an innovative production control method known as Constant Work-In-Process. CONWIP represents a notable advance over the well-known Kanban approach of the Toyota Production System that outperforms Kanban under a wide range of settings, is more adaptable to variability, and, unlike Kanban, is suited to environments with a large number of products. The path-breaking analysis of this paper spurred a significant stream of research into the performance of pull production systems that continues to this day. CONWIP has also become a standard part of the operations lexicon and has seen widespread application in industrial settings. Finally, CONWIP was an essential building block of the science of manufacturing that Wally and others introduced as Factory Physics in subsequent work. 

Professor Charles Laselle Jamison, a pioneering figure in the sphere of business management, spent most of his career at the Michigan Business School. Recognizing the importance of the evolving field of management education in 1936, Jamison proposed an organization dedicated to the support of high-quality research, teaching, and practice in the field. His vision led to the official launch of the Academy of Management in 1941. For this instrumental role, he became known as the "Father of the Academy of Management." With the onset of World War II, the Academy's operations were put on hold. However, they were revived in 1947 thanks to Jamison's tireless commitment. Since then, the Academy of Management has become an internationally recognized association for management and organization scholars.

Later in his career, Jamison would cement his legacy as a pioneer in the field of strategic management by publishing his 1953 textbook on business policy. The textbook was one of the first on the subject and showcased his invaluable contribution to the field.

Professor Joel Slemrod has worked on an agenda to broaden the scope of tax analysis to address several issues that standard economics models of taxation ignore. He has written several articles analyzing and addressing the blind spots of standard economics models and has co-authored a book titled Tax Systems, which outlines the implications of these blind spots. The influence of his work is demonstrated by the recent policy attention given to tax enforcement in the United States and other countries, such as an increase in funding appropriated to the IRS to reduce evasion of high-income individuals and corporations, as well as innovative administrative policy developments through the U.S. Foreign Account Tax Compliance Act and the OECD Pillars One and Two, which subjects a group of large multinational companies to a global minimum corporate tax of 15%. Slemrod's work has received over 35,000 citations, numerous awards and accolades, and a No. 1 ranking among public finance economists per the Research Papers In Economics site.

The root of the Great Financial Crisis of 2008-2009 lay in poor-quality residential mortgage loans made by financial institutions. A set of academic research papers established that lenders made poorer quality loans when they anticipated selling the loans to investors rather than continuing to own the loans until they matured. When loans were sold, a complex securitization process led to a large distance between the originator of a mortgage and the final investor in the loans. Amit Seru, PhD '07, and co-authors established in an important series of papers that focused on 1) keeping most characteristics of loans the same, loans that were only marginally easier to securitize had significantly higher default rates than those that were marginally more difficult to securitize, 2) (in work with Professor Uday Rajan) securitized loans, the interest rate (which represents the compensation to investors for bearing the risk of default by the borrower) became an increasingly worse predictor of default in the build-up to the GFC, and 3) information passed on to investors by mortgage securitizers was limited and sometimes outright fraudulent. In another crucial strand of work, Professor Amiyatosh Purnanandam demonstrated that 1) loans held by banks on their own balance sheets had lower default rates than otherwise identical loans sold by banks to investors and 2) (in work with Taylor Begley, PhD '14, and Kuncheng Zheng, PhD '15) even with securitized loans, default rates were lower when the riskiest tranche was held by the lender rather than sold to investors. Collectively, the work done by Ross faculty and PhD alums showed that the ability to securitize mortgage loans undermined the incentives of lenders to the point that low-quality mortgage loans were made, essentially providing the dry timber that fueled the GFC.

In 2002, Professor Ravi Anupindi and his co-authors published the influential paper "Coordination and Flexibility in Supply Contracts with Options" in Manufacturing & Service Operations Management. This work introduced an innovative model that integrated options into supply contracts, offering enhanced management of demand uncertainties in supply chains. The research highlighted the important potential role of options in attaining contractual flexibility to coordinate supply chain participants and improve overall efficiency. The paper influenced subsequent research on supply contract design and demand management, one of the major areas of supply chain management research in the past two decades.

The paper "Value of Information in Capacitated Supply Chains" by Professor Roman Kapuscinski and his co-authors was published in Management Science in 1999. This paper contributed significantly to the understanding of how information sharing impacts the performance of supply chains. Specifically, this paper turned on its head the notion that information would be most valuable in settings where capacity is tight, when the uncertainty of demand is huge, and when the costs of unsatisfying demand are very high. The paper uses careful, rigorous analyses to reveal when information is most valuable and how the value depends on many interrelated factors. Providing an innovative analytical model, Kapuscinski and his colleagues demonstrated when and how the sharing of demand information could remarkably enhance inventory management and order fulfillment for capacity-constrained supply chains. The subsequent literature in operations management has heavily referenced this pioneering work, leading to the development of practical strategies for improving supply chain efficiency through information sharing. Further studies have explored different facets of information sharing in diverse supply chain settings and have considered more complex forms of information, extending the paper's impact in many directions within operations. 

Beginning from seminal efforts by Brian Talbot at the Michigan Business School in the early 1990s, the Tauber Institute for Global Operations was designed to bring business and engineering students together for a world-class education in operations. Students would take classes in both business and engineering and complete team projects with companies. The projects were scoped to incorporate both business and engineering content, addressing important problems that had a VP-level champion at the sponsoring company. The institute was innovative by offering additional training to students beyond operations: leadership training, communications training, and providing students the opportunity to organize conferences, etc. In addition to its impact on students and companies, the Institute has for years served as an important mechanism fueling the technology and operations faculty's relevant, problem-driven research by putting them in touch with practitioners at leading companies around the world. Since its foundation, more than 1,500 graduates have completed the program as Tauber Fellows, there have been 720 summer projects executed at 145 companies, and the Institute was honored in 2012 with the prestigious UPS George D. Smith Prize from INFORMS.

The Personal Development Plan is a simple but impactful idea that has now been utilized by approximately 6,000 BBA alums and current students. At its core, the PDP is an Excel document that helps students plan the requirements to graduate, but its usage and value go far beyond just a requirement planning tool. In 2006, the BBA degree, which had for decades been a two-year degree program, was modified to a three-year structure with a small number of first-year preferred admits. Eight years later, in 2014, the BBA curriculum was modified from a 45 business credit requirement to 58 business credits. The changes to the curriculum meant that students had significantly more time, more flexibility, and more choices in how they progressed through the BBA degree. That flexibility increased even more as we moved to a four-year program in 2017. Advisors developed the PDP as a resource to help students make the most out of this expanded college experience.

In 2014, with the launch of the 58-credit BBA curriculum, a new core course was created, BA 200. As part of BA 200, PDP was introduced as a required component of the class and is now a co-curricular component of BA 100 and BA 102. Each year, the undergraduate advising team works with over 625 new BBA students (first-year students and transfers) so that each student develops an individualized plan for their life as a college student. Ensuring that they are planning requirements is an important part of this, but in developing their plan, students are asked to reflect on their goals for their time in college while developing their PDP. What skills and competencies do they hope to develop while they are here? Are there opportunities they want to take advantage of (study abroad, participation in programs through centers and institutes, minors or dual degrees, club leadership, etc.)? The PDP is a living document that travels with students throughout their four years and becomes a reference point for continued conversations and relationship-building with advisors until graduation. The PDP has had an impact on every single BBA student since the fall of 2014, helping to open their eyes to the rich opportunities at Michigan Ross and giving them a roadmap to their unique journey as a Ross BBA.

The Affordable Care Act represented arguably the largest change in federal health policy since the creation of the Medicare and Medicaid programs in the 1960s, expanding coverage to approximately 40 million people who were previously uninsured. In a series of papers published in the Quarterly Journal of Economics, New England Journal of Medicine, AEJ: Applied Economics, Journal of Public Economics, and other outlets, Associate Professor Sarah Miller and her co-author Dr. Lara R. Wherry quantify the impact of this policy on the predominantly low-income population who gained coverage as a result of the reform's resultant changes in Medicaid eligibility. Their work has shown that 1) low-income adults who gained coverage through the ACA Medicaid expansions experienced reduced mortality rates and that the failure of some states to adopt these expansions cost approximately 4,800 deaths per year in those states; 2) low-income adults who gained coverage through these expansions experienced improved access to medical care and improved financial outcomes; 3) the expansion of coverage to these individuals did not crowd out care provided to population who were unaffected, such as those in Medicare. This work has garnered over 1,800 citations and has been discussed in numerous high-profile media outlets and policy documents.

The Michigan Business Challenge is a prestigious business plan competition hosted by the Zell Lurie Institute for Entrepreneurial Studies. It allows U-M students to showcase their entrepreneurial ideas, receive feedback from experienced judges, and compete for over $100,000 in cash prizes to support their ventures. 

The Michigan Business Challenge was established in 1984 at Michigan Ross and has since become one of the region's most impactful and well-known startup competitions. Over the years, the MBC has supported numerous successful startups, generated millions of dollars in funding, and helped launch successful entrepreneurial careers for U-M students and alumni. The MBC is open to various stages of business concepts, from early-stage ideas to established businesses. 

The competition consists of three tracks that cater to specific industry sectors, including the Seigle Impact Track for social ventures, the Invention Track for ventures that have intellectual property at the core of their high-tech venture, and the Innovation Track for growing startups. These tracks provide tailored resources, networking opportunities, and funding for participants. Notable entrepreneurial ventures that have come through the MBC include Morning Brew, Xoran Technologies, AMBIQ Micro, Elevate K-12, and many more.

Originally launched by Michigan Ross Professor David Brophy and now organized and run by the Zell Lurie Institute for Entrepreneurial Studies, the Midwest Growth Capital Symposium began as an opportunity to showcase innovative Michigan ventures seeking funding and connect them with venture capitalists, angel investors, industry stakeholders, and leaders from across the nation. 

Today, the Symposium provides a platform for pre-selected Midwest companies to present their business ideas and investment opportunities. These companies span various sectors, such as life sciences, healthcare, technology, food and agriculture, and energy. First held in 1980, the Symposium is the longest-running university-based venture fair of its kind, has gained recognition, and attracts attendees from across the country.

The 1996 book Competing for the Future by the late Professor C.K. Prahalad and his colleague, Gary Hamel from the London Business School, was unique in that it tied together several of Hamel and Prahalad's leading ideas into book format. The book introduces the concept of "core competencies," which emphasizes that organizations should focus on leveraging their inherent strengths and unique capabilities, and "strategic intent," which focuses on setting an ambitious, long-run vision for a firm's future. This emphasis on future thinking was a particularly notable aspect of the book. In general, the book advocated for a proactive approach to strategy where businesses actively envision and shape the trajectory of their respective industries instead of merely reacting to existing competitors and market dynamics in the short run. This emphasis on dynamics -- in particular, envisioning the future and then mobilizing strategy to compete in shaping it -- had important managerial implications for business thinking in the 1990s.  It suggested that companies needed to transition from a short-term, reactive mindset to a more forward-thinking, visionary stance; this would allow companies not just to survive but dominate in future market landscapes. Overall, this book had a notable impact on business practice; Time Magazine named it one of "The 25 Most Influential Business Management Books."

Professor Gautam Kaul and two former PhD students, in their seminal 1994 study titled, "Transactions, Volume, and Volatility" convincingly argued and verified empirically that it is the occurrence of a trade in a certain direction rather than its dollar value (or volume) that has the greatest effect on prices, hence the greatest relevance when assessing the liquidity of the market where that trade took place. A trade sign is determined by the buyer or seller's information, while market conditions determine trade amount and price. This is a simple yet extremely powerful notion that was originally predicated in theory but had no empirical support before their 1994 study. The publication of this study opened the door to the accurate measurement and needed assessment of market liquidity. These days, the approach they recommended is widespread in its use.

In the 1990s, a research team at Michigan Ross, led by Emeritus Professor Claes Fornell, created the American Customer Satisfaction Index. This groundbreaking project included Professors Eugene Anderson and Michael Johnson, as well as Research Scientist Jaesumg Cha and Barbara Everitt, former director of the U.S. Census Bureau. 

ACSI represents a paradigm shift in measuring market performance, offering a more complete view of firms, industries, and economies and treats customer satisfaction as a latent construct connecting expectations, perceived quality and perceived value, through customer satisfaction, to customer voice and loyalty. For the past three decades, ACSI has catalyzed a wealth of peer-reviewed research in marketing and business. Empirical studies consistently find ACSI positively associated with profitability, cash flows, stock returns, credit ratings, positive earnings surprises, revenue, gross margins, return on investment, cash flow stability, and operating margins. Greater ACSI is also associated with lower cost of capital, cost of debt, and selling costs. At a macro level, ACSI is found to be predictive of gross domestic product. 

Published research by the ACSI team enjoys wide recognition, garnering more than 100,000 citations. Additionally, ACSI-related research has played an outsized role in establishing customer satisfaction as an essential metric within firms' management information systems, priority setting, and key performance indicators.

In 2018, Professor Tom Lyon led a team of scholars who published a groundbreaking article about corporate political responsibility titled “CSR Needs CPR” in the California Management Review. The article argued that corporate social responsibility was an insufficient measure of corporate contribution to society and that stakeholders who care about CSR should also pay attention to corporate political responsibility. In 2019, Elizabeth Doty, adjunct faculty at Presidio Graduate School, contacted the Erb Institute at the University of Michigan and suggested turning the article into an industry roundtable dedicated to working with a select group of influential business leaders and their companies to bring to life the core precept of the article – the need to better align companies’ political spending and lobbying with their commitments to values, purpose, sustainability, and stakeholders. Thus, the Erb Corporate Political Responsibility Taskforce was founded in 2020. Lyon and Doty have developed the taskforce into a nationally recognized forum with the goal of making CPR a new norm for business. The taskforce operates under Chatham House Rule and has 20 members from some of the most recognized brands in the United States who share best practices and address CPR challenges. In 2023, the taskforce released the non-partisan Erb Principles for Corporate Political Responsibility, with five major companies as inaugural signatories. Looking ahead, the taskforce will continue building its integrated framework and engage more companies in applying the Erb Principles. Lyon continues his work in this space with his recently published volume Corporate Political Responsibility.

Four student-run venture funds are currently operating at Michigan Ross, more than any other business school. Collectively, these funds manage a portfolio worth more than $10 million. These funds help students learn about investing early-stage capital by making real deals with real companies and real money. The concept of student-run venture funds has been adopted by universities around the world.
