Chapter 1:  Foundations of Information Systems in Business Chapter 1 Learning Objectives:  Explain why knowledge of information systems is important for business professionals and identify five areas of information systems knowledge they need. Give examples to illustrate how the business applications of information systems can support a firm’s business processes, managerial decision making, and strategies for competitive advantage. Learning Objectives Learning Objectives:  Learning Objectives Provide examples of several major types of information systems from your experiences with business organizations in the real world. Identify several challenges that a business manager might face in managing the successful and ethical development and use of information technology in a business. Learning Objectives:  Learning Objectives Provide examples of the components of real world information systems. Illustrate that in an information system, people use hardware, software, data and networks as resources to perform input, processing, output, storage, and control activities that transform data resources into information products. Why Study Information Systems?:  Why Study Information Systems? Information technology can help all kinds of businesses improve the efficiency and effectiveness of their business processes, managerial decision making, and workgroup collaboration, thus strengthening their competitive positions in a rapidly changing marketplace. Why Study Information Systems:  Why Study Information Systems Internet-based systems have become a necessary ingredient for business success in today’s dynamic global environment. Information technologies are playing an expanding role in business. Case #1: Athens Olympics Network:  Case #1: Athens Olympics Network What makes the Olympic Games a unique project is that the athletes aren’t going to stop running just because the server does. Major Components: Games Management System (GMS) Information Diffusion System (IDS) Case #1: Athens Olympics Network:  Case #1: Athens Olympics Network GMS: Managed access accreditations for the games IDS: Collected and distributed event results and rankings to press agencies and certain websites Live feed for broadcasters commenting on events Results, rankings, statistics and biographies available to commentators .3 seconds after the athletes crossed the line Case #1: Athens Olympics Network:  Case #1: Athens Olympics Network Goals & Constraints: Reduce the amount of risk 100% availability Non-negotiable deadline Case #1: Athens Olympics Network:  Case #1: Athens Olympics Network Fail-Safe Plan: Redundancy Constructed the network in such a way that service could be provided even if one of the routers was damaged. Stored data in two physically distant data centers (in different earthquake zones). Test. Test. Test. “We wanted to be sure that every stupid thing that can happen was planned for.” Case #1: Athens Olympics Network:  Case #1: Athens Olympics Network Could the 2004 Athens Olympics have been a success without all of the networks and backup technologies? How would your 2004 Olympics experience changed without the GMS and IDS systems? The 2004 Olympics is a global business. Can a business today succeed without information technology? Why or why not? Case #1: Athens Olympics Network:  Case #1: Athens Olympics Network Claude Philipps said dealing with the “crazy scenarios of what might happen in every area: a network problem, staff stopped in a traffic jam, a security attack… everything that might happen,” was the reason for so much testing. Can you think of other businesses that would require “crazy scenario” testing? Explain. Case #1: Athens Olympics Network:  Case #1: Athens Olympics Network Are the redundancies and backup systems in place limited to one-time systems like those at the Olympics or should they exist in other business environments? Explain your position and provide specific examples. What is an Information System?:  What is an Information System?

Case #4: This Call is Being Monitored:  Case #4: This Call is Being Monitored Goals: Increase customer loyalty Reduce number of calls forwarded to internal help desk Improve decision making Case #4: This Call is Being Monitored:  Case #4: This Call is Being Monitored Witness Systems Call-center Software & CallMiner: Records conversations Captures keystrokes Tracks caller choices Transcribes conversations into text Case #4: This Call is Being Monitored:  Case #4: This Call is Being Monitored Benefits: Revenues increased 60% 20% fewer calls sent to help desk saving $1 million Customer satisfaction rose 10% E-ticket sales increased 8% Reduced staffing needs Case #4: This Call is Being Monitored:  Case #4: This Call is Being Monitored What are the business benefits of the CallMiner system? Provide some additional examples beyond those discussed in the case. How can new technologies like CallMiner help companies improve their customer service and gain a competitive edge in the marketplace? Explain. Andre Harris refers to calls to reconfirm a flight as “quite frankly, low-value calls.” Why are they classified as low value? Why do you think so many customers are placing such calls? Summary:  Summary There is no longer a distinction between an IT project and a business initiative. Information systems are an important contributor to operational efficiency, employee productivity and morale, and customer service and satisfaction. Summary:  Summary Information systems are a major source of information and support needed to promote effective decision making by managers and business professionals. Information systems can be categorized based on their intended purpose.
