34. Real World Case: JetBlue and the Veterans Administration Good IT processes are as important as hardware and software when it comes to creating business value through the use of technology. Even seemingly smaller and less critical processes can have ramifications of a large magnitude in the interconnected world in which we live. The information system, which was developed by JetBlue in 24 hours and implemented in the middle of crisis in 2007, has now been implemented as a full-time system in the company. At Veterans Administration an unscheduled system failure took down key applications in 17 (VA) medical facilities for a day. 1-

35. Case Study Questions Eric Brinker of JetBlue noted that the database developed during the crisis had not been needed before since the company had never experienced a meltdown. What are the risks and benefits associated with this approach to IT planning? Provide some examples of each. With hindsight, we now know that the decision made by Eric Raffin of the VA not to fail over to the Denver site was the correct one. However, it involved failing to follow established backup procedures. With the information he had at the time, what other alternatives could he have considered? Develop at least two of them. A small, undocumented change resulted in the collapse of the VA system, largely because of the high interrelationship between its applications. What is the positive side of this high degree of interconnection, and how does this benefit patients? Provide examples from the case to justify your answer. 1-

36. What is a System? A system is… A set of interrelated components With a clearly defined boundary Working together To achieve a common set of objectives By accepting inputs and producing outputs In an organized transformation process 1-

37. Basic Functions of a System Input Capturing and assembling elements that enter the system to be processed Processing Transformation process that converts input into output Output Transferring transformed elements to their ultimate destination 1-

38. Cybernetic System All systems have input , processing , and output A cybernetic system , a self-monitoring, self-regulating system, adds feedback and control: Feedback is data about the performance of a system Control involves monitoring and evaluating feedback to determine whether a system is moving toward the achievement of its goal 1-

46. Recognizing Information Systems Business professionals should be able to look at an information system and identify… The people, hardware, software, data, and network resources they use The type of information products they produce The way they perform input, processing, output, storage, and control activities 1-

47. Case 3: Heidelberg, Honeywell, and Eaton Today, it is not be enough for a company to offer services but it will have to provide “smart services.” To provide smart services, companies must use information technology to build “smart products.” Smart products can detect that a part is approaching failure and alert users, thus giving the company opportunity to provide maintenance services and enjoy the resulting benefits. Heidelberg developed the technology to monitor its equipment remotely, using built-in sensors, networking microprocessors, and other information technologies. With such smart services, Heidelberg now offers total support of its products. Eaton corporation has developed a product called Home Heartbeat which monitors the status of various home systems and alerts the homeowner when something is wrong. 1-

48. Case Study Questions Why should manufacturing companies build smart products and provide smart services? What business benefits can they gain? Provide several examples beyond those discussed in this case. What information technologies are used by the companies in this case to build smart products and provide smart services? What other IT components might be used? Give examples of the capabilities they would provide. What are some limitations of a smart products and smart services strategy? Give several examples of challenges that a business might encounter, and explain how it might overcome them. 1-

49. Case 4: Lufthansa In 2001, Lufthansa launched the “Lufthansa Mobile Initiative,” which aimed to provide all pilots with notebook computers. It helps 3,500 highly mobile airline pilots plugged into the corporate infrastructure, that informs them about schedules, weather events, and other facts that affect their jobs throughout the world. The Lufthansa Mobile Initiative is yielding significant productivity and efficiency improvements, while keeping costs manageable. Pilots use their notebook computers for computer-based training whether they are learning about new aircraft or things like specific hydraulic systems. 1-

50. Case Questions Are many of Lufthansa’s challenges identified in the case similar to those being experienced by other businesses in today’s global economy? Explain and provide some examples. What other tangible and intangible benefits, beyond those identified by Lufthansa, might a mobile workforce enjoy as a result of deploying mobile technologies? Explain. Lufthansa was clearly taking a big risk with their decision to deploy notebook computers to their pilots. What steps did they take to manage that risk, and what others might be needed in today’s business environment? Provide some examples. 1-
