A credit-card company must value portfolios of customers based on their future earnings. The payment characteristics of customers serve to classify them into states. This case can be the basis for discussing state dynamics over time in a Markov process.

Microsoft is planning the introduction of Internet Explorer along with Windows 95. Issues include how aggressive the company should be in providing its browser with Windows 95 and restricting OEMs (original-equipment manufacturers) from putting other browsers on their computers. Should Microsoft go for initial share, concentrate on stealing over time, retain customers, or enlarge the total size of the browser market? Students use a Markov process with initial states and switching probabilities to gain insight into resolving these issues.

Supply chain management.

The case is suitable for post graduates in management, and for those managing small sector supply and manufacturing systems.

ACPL is an organisation which moved from trading to manufacturing a technology product instrument transformers (ITs) for power utility companies for 11 years, competing with the best in industry, reducing internal costs, and modernising the supply chain. ACPL was started as a trading organisation in electrical items in Delhi by Munish Kumar, an engineer by profession in 2001. In 2004 he ventured into manufacturing, which expanded in two locations in Ghaziabad, NCR Delhi. Later his two sons, engineer and management graduate, respectively, joined the organisation. In less than a decade, by 2007, ACPL had grown to be a private limited organisation. ACPL manufactures ITs required by power boards and companies for conversion and usage of high voltage (11 kV/33 kV) transmitted power into 220 V single phase/440 V three phase power. From tender/enquiry through manufacturing to inspection and despatch takes a long supply chain cycle time holding space as well as inventory. An interview with the chairman of ACPL in the case highlights issues affecting its margins and growth. The long process to delivery time may be in vogue in this type of industry but this holds up a huge inventory. The company management has been working to resolve this crisis along with an urgent need to grow in a competitive environment. The problem is being addressed.

This case study should help students to understand the concept of the supply chain and supply cycle, in a manufacturing company in particular. It has been found that students understand the supply chain as part of the marketing function dealing with finished stocks, warehousing and delivery to end customers as per agreements, and arranging payments from customers. The supply chain also deals with in bound materials management. Raw materials planning, purchasing, inventory management are crucial for effective business operations management in any organisation.

The key objectives of this case are to: (1) familiarize students with a simple version of the Markowitz optimal-asset allocation model; (2) develop students' intuition regarding optimal-asset allocation as specific inputs into the model (e.g., expected returns, standard deviations, correlations) change values; and (3) develop students' intuition regarding constraints that alternative investors may face (e.g., the presence of shorting constraints) and their impact on the optimal portfolio. The case includes an Excel spreadsheet, which contains relevant data (e.g., returns, standard deviations, correlations) on several assets and an Excel model that takes three of those assets and makes use of the Excel Solver Add-In to compute optimal weights for the three asset portfolio as well as the expected return, standard deviation, and Sharpe ratio of the optimal portfolio. Students are asked to alter many of the inputs into the model and explain the effects of those changes on the optimal portfolio.

Crutchfield, a large U.S. mail-order firm specializing in consumer electronics and personal computers, must evaluate the results of a recent "prospecting" mailing to a rented list of names. A determination of the mailing requires the calculation of the lifetime value of the new customers acquired. Case data on repurchase probabilities (broken out by recency and frequency) support such a calculation. The case can also be used to introduce the RFM (recency, frequency, monetary value) framework for valuing customers.
