This is an MIT Sloan Management Review article. Dan Ariely is one of the world's foremost experts in behavioral economics, the study of how people behave when making business and financial decisions. Ariely's insights should make executives think twice about the wisdom of the decisions they regularly make -- as well as the inner processes they rely on to make those decisions. Why, for example, will managers veto a 10% cost increase for a $1 million project while thinking nothing of a 1% overrun on a $10 million budget -- even though the actual amount is the same? Why will they often agonize trying to choose between two close alternatives when they're frequently better off just flipping a coin? In this wide-ranging interview, Ariely talks about how Apple Inc.'s initial decision to price the iPhone at $600 only to drop it to $400 soon after might not have been a mistake but instead a very shrewd marketing maneuver. He also explains why a product monopoly might not necessarily be desirable because it can lead to consumer confusion, resulting in slow sales. With regards to hiring practices, Ariely strongly questions the interviewing processes routinely used and asserts that some companies might be better off hiring graduates from reputable colleges at random. Toward the end of the interview, he describes his research that has investigated ways in which teams might be better able to make group decisions. Lastly, Ariely explains one of his most valuable managerial insights -- that adding even just a little meaning to employees' work will often increase their motivation enormously.

This is an MIT Sloan Management Review article. One could argue that "what business are we really in" is the most important question a leader can ask about his company. But perhaps right up there with the classic Peter Drucker interrogatory is this one: What is your business model? So argue the authors, who correctly point out that firms searching for forms of competitive advantage -- sources of distinctiveness that are enduring, hard to copy and valuable in the marketplace -- should take a look at their management model. That is, they should examine the choices made by the top executives in how they define objectives, motivate efforts, coordinate activities and allocate resources. How they define the work of management, in other words. Not only do the authors provide a framework for this discussion -- dividing companies' business models into four possible choices -- but they supply a list of questions leaders can ask to determine which management model may be right for their company. Clearly, when it comes to management models, one size does not fit all. And it is equally obvious that even similar-size companies in the same industry may choose differing models, depending on their own particular circumstances. While the model they choose is of extreme importance, so, too, is the process they follow--and the thinking they use--to select it.

Berkshire Hathaway is known to many as the investment vehicle of Warren E. Buffett. To some extent, this reputation is well founded, given the investment success that the company has enjoyed under his leadership. Less attention, however, has been paid to the management success of Berkshire Hathaway. By 2008, the array of companies that Berkshire Hathaway owned was unique in its diversity. Even more unique was the operating structure that the company employed to manage these operations. It was a model based on extreme decentralization of operating authority, with responsibility for business performance placed entirely in the hands of local managers. While many public corporations implemented strict controls and oversight mechanisms to ensure management performance and regulatory compliance, Berkshire Hathaway moved in the opposite direction. Many of the company's operating principles were in stark contrast to those generally employed by most public corporations. Company shareholders would have to decide for themselves whether these operating principles posed a risk to long-term performance or whether, contrary to expert opinion, they were a source of competitive advantage that could be sustained in the future.

Thinking of a second career in the social sector? You're not alone. And your current employer would be wise to help you train for it.

The case considers the steadily deteriorating relationship between BA's top management and its cabin crew union - and highlights the self-fulfilling and self-reinforcing nature of the dysfunctional dynamic that develops between the three key parties. We concentrate on the cognitive, motivational and behavioral mechanisms that drive the parties toward an avoidable stalemate. The airline ultimately got its way, but at the expense of a three-day strike estimated to have cost £125 million. In the process, it also inflicted huge damage on employee morale and corporate reputation. The strike proved to be a turning point in BA's fortunes, sending the once soaring share price into a long decline - as measured against its direct competitors. Although Ayling's radical cost-cutting strategy was in many ways farsighted, it was implemented in a way that alienated staff and angered the unions - moves that ultimately sent the company crashing out of the FTSE100. Learning objectives: We have written this case in response to demand from instructors to provide material for teaching the set-up-to-fail syndrome in different courses and in different contexts than the typical dyadic boss-subordinate relationship. This case shows how the process plays out in an intra-organizational situation between a company and its union - though a similar dynamic could easily develop with other stakeholders such as suppliers, alliance partners, shareholders, analysts or NGOs. It is a case about individual "opponents" who demonize each other - thus triggering a gigantic self-fulfilling and self-reinforcing process. The key lesson is that leaders and their teams have to be careful about labeling processes toward other parties. When they start caricaturing another stakeholder, they risk triggering vicious spirals.

Well aware of your experience and keen intuition, the newly appointed Chief Executive Officer of XYZ Airlines, James Sanchez, is asking for your help. The airline is loss-making, has a record of poor customer service, and is the result of an undigested merger several years ago. Sanchez took over as chief executive of XYZ Airlines a month ago. Well-known for his almost single-minded focus on customer service, he wants to create a service culture in the airline while continuing to cut costs. He is asking for your help to decide what he should do to create this culture change and to estimate how long it will take to succeed. Learning objectives: Participants are challenged to think about the critical success factors for changing the culture of an organization.

Two years after joining the LEGO Group as their Logistics Manager for Europe and Asia, Egil Møller Nielsen finds himself fighting several battles at different fronts; the most difficult one on his home turf against his own management team. He is half-way implementing a bold plan: close down all existing local and regional logistics operations and consolidate all logistics and distribution activities from a central location in the Czech Republic, managed by an external partner - DHL. Outsourcing logistics services on a scale like this - in East-Europe - had never been done before by any other European company. The stakes are high as LEGO, struggling for survival, is also trying to re-invent itself. Should Nielsen push through his plan - in which he firmly believes - or give in to the mounting pressure from home and relax his efforts? Learning objectives: We observe two new partners, both active on new, unexplored territory in the early stages of their partnership. The relationship is strained; both companies are under tremendous pressure from their corporate headquarters to show results while there is a general distrust in each others capacity and motivation. In this first case we learn that building a relationship that is based only on a contractual agreement can be a painful experience. Cost accounting in general and cost drivers in specific are mentioned to illustrate their importance in key decision making.

The Global Health Initiative (GHI) is a tripartite collaboration among Northwestern University, non-profit donors, and commercial diagnostics companies. GHI attempts to bridge the gap between the market for sophisticated medical diagnostics equipment in wealthy nations and the need for point-of-care diagnostics in resource limited settings. In 2006 GHI narrowed its focus to HIV diagnostics for underserved nations. The case examines the accuracy-access tradeoff related to the roll-out of infant HIV diagnostics in Tanzania. Tanzania has a prevalent HIV/AIDS problem, particularly in children. As of 2007, Tanzania had an estimated 140,000 children infected with HIV. Existing lab-based diagnostic equipment was either inaccurate for use in infants or required highly skilled health workers. Tanzania's limited infrastructure also forced healthcare providers to choose between providing advanced care to a minority of the population and offering minimal care to the majority with poor access. A Kellogg MBA student research team performed more than thirty in-country interviews to collect data on stakeholder perceptions of three infant test concepts: the strip test, the squeeze test, and the filter paper test. Across the three tests, access decreased as accuracy increased-rural labs could not find or afford health workers skilled enough to conduct the test. In general, interviewees closely affiliated with the government preferred accuracy over access. In contrast, private health facilities had to follow fewer regulations and preferred access over accuracy. The case focuses on the decisions facing Kara Palamountain, the executive director of GHI, in her roll-out recommendations for infant HIV tests in Tanzania. It examines key factors of working in a developing country, including the need to operate in the absence of sufficient market research, balance the competing agendas of different stakeholders, and mitigate external risks such as major international funding drying up.

This case is suitable for graduate-level quantitative analysis, business and government, environment and sustainability, and global economics courses. Students must consider the tradeoffs between continuing to run an old coal-burning plant and purchasing emissions allowances (EAs) versus upgrading to emissions-reducing wet or dry scrubbers. Reducing emissions creates the possibility of selling the plant's surplus EAs (which are likely to increase in price). Choosing a wet or dry scrubber requires considering installation cost and construction time, variable cost, and SO2 removal efficiency. Ideally, the investment should pay back over time, but management believes some net investment could also be justified. For that, however, complete analyses from both economic and environmental perspectives are required. A supplemental spreadsheet is available to accompany the case (UVA-S-QA-0726).

In September 2003, British Petroleum (BP) formed a 50/50 international joint venture (JV) company, TNK-BP, with a group of Russian investors: Alfa Group, Access Industries and Renova (AAR). This JV was established as a result of the merger of Russian oil companies TNK and Sidanko, owned by AAR, with the majority of BP's Russian oil assets. On May 26, 2008, TNK-BP's chief executive officer, Robert Dudley, told Vedomosti, Russia's leading business daily, about a conflict between British and Russian shareholders. During this dispute, AAR declared that BP treated TNK-BP as its subsidiary and not as a JV. Also, the Russian shareholders criticized the JV's leadership of the company's expansion strategy and climate. As the conflict escalated, BP's leadership needed to decide whether to walk away or continue its participation in the JV.

This case chronicles a change process to counteract the epidemic of HIV/AIDS on a coalmine in South Africa that impacts the sustainability of the organization. The case describes the business case for dealing with the problem and the sequence of events that were instituted. It illustrates the type of leadership activities needed to deal with a compelling environmental force impacting business. It shows how a wide range of stakeholders needs to be involved and systems and practices instituted for sustainable change to be implemented. It raises the question of the role of business in society. The case also provides insights into doing business in emerging economies. The challenge at the end of the case is how to roll out (replicate) the intervention into other divisions of a large multinational.

The general manager of the Guam Visitors' Bureau, a destination marketing organization, faces the challenge of running the island's tourism industry. There are strong interest groups, who have structured the competitive field in Guam, and the island's mature industry faces ever-increasing competition from rival destinations. The general manager must formulate a realistic strategy that acknowledges the internal and external constraints his organization faces and safeguards the competitive position of Guam.

The owner of a carpet cleaning operation in Tennessee is urgently looking for solutions, after his business expansion project has failed. The owner has emulated the business model of a well-established competitor, hoping that what has worked for his competitor would also work for him.

The chief executive officer (CEO) of West Lake Furnishings Ltd. (West Lake) has been given a proposal from one of his top three wholesale customers: lower the price of a line of signature lamps from $69.99 to $29.99 in exchange for five times the unit sales. The decision point of the case focuses on whether the CEO should or should not take the offer, and answering the question requires a close examination of West Lake's business strategy and its industry. The West Lake case is a short, comprehensive case that is useful for time-pressured situations like case competitions or exams. It can also be used to introduce the Five Forces, or give an overview/review of the entire strategic analysis process.

The Dell story is well-known in the business world: a young Michael Dell, while attending the University of Texas in Austin, founds a computer sales company that eventually revolutionizes the industry. The case puts students in the position of a senior executive at Dell who is preparing for an investor relations meeting. As the senior executive reviews information on his company, he wonders how best to convey to skeptical investors that Dell's strategy will return the company to growth. In examining the Dell story, students learn about how Dell built up a set of competitive advantages that seemed unassailable until the early 2000s. The second part of the case illustrates the impermanence of competitive advantages - it describes how Dell is attempting to remake itself after falling behind its competitors.
