Ultimately, it may turn out that the customer was thinking all along of a small blue marble. At each subsequent meeting with the customer, the developer may exclaim, "You want it to do what? To complicate matters, in most real projects, more than two individuals are involved. In addition to the customer and the developer-who may, of course, have very different names and titles-there are likely to be marketing people, testing and quality assurance people, product managers, general managers, and a variety of "stakeholders" whose day-to-day operations will be affected by the development of the new system. Moreover, for thousands of companies today, those companies whose business is dedicated exclusively to the development and sales of software products, their entire business focuses on making their products-intangible and abstract as they are-into tangible rocks that their customers can purchase, evaluate, and apply.

Managing Software Requirements: A Use Case Approach, Second Edition by Dean Leffingwell, Don Widrig

The primary focus in this book is on how households adjust these expenditures in response to changes in price and income. Econometric estimates of price and income elasticities are obtained for an exhaustive array of goods and services using data from surveys conducted by the Bureau of Labor Statistics, providing a better understanding of consumer demand. Practical models for forecasting future price and income elasticities are also demonstrated. Fully revised with over a dozen new chapters and appendices, the book revisits the original Taylor-Houthakker models while examining new material as well, such as the use of quantile regression and the stationarity of consumer preference. It also explores the emerging connection between neuroscience and consumer behavior, integrating the economic literature on demand theory with psychology literature. The most comprehensive treatment of the topic to date, this volume will be an essential resource for any researcher, student or professional economist working on consumer behavior or demand theory, as well as investors and policymakers concerned with the impact of economic fluctuations.
