...Week 1: Information Systems in the Digital Firm - Lecture | | | Information Systems in the Digital Firm Evolution | Current State | Trends | Tutorial The Evolution, Current State, and Trends of Information Systems In addition to the material currently described, an introduction to cloud computing and user involvement in IT projects also will be included in this lecture. This is required as foundational knowledge for the chapters to come. We will explore it at a business level and a minimal technical level. | | Evolution | | The business landscape has changed over the past seventy years in every significant way. Without information systems, these changes would not have occurred. To gain a perspective on the evolution of information systems, we can review the significant computer inventions from the first computer through to cloud computing. As computer technology progressed, new skills had to be learned, and new methods of management evolved to replace old hierarchical styles with new team based methods. Increased productivity resulting in new information technology caused the downsizing of employees that began in the late 1980s and has continued. Information systems consultants identified productivity gains, so large that they cut the numbers in half and still weren't believed. Many of the products and services we use every day had not been invented just five or ten years ago. The ability to communicate electronically with anyone anywhere in the world...

...CLOUD COMPUTING: PAST, PRESENT, AND FUTURE John P. Sahlin (sahlinj@gwu.edu) The George Washington University, United States of America ABSTRACT Defining cloud computing can be difficult, as each organization often has its own spin on the definition. Despite being hard to define, Gartner Research named cloud computing as one of the top technologies to watch in 2010, 2011, and 2012. At its core, cloud computing is a technical architecture that meets a specific business need. This chapter traces the roots of cloud computing from its origins in mainframe distributed computing, discusses the basics of the cloud computing model today, and offers insights for future directions that are likely to be pursued in the cloud computing arena. A number of challenges to cloud computing are identified, including concerns of security and how to deal with the rise of mobile computing. The chapter ends with recommendations on how to choose which cloud model is most appropriate to meet your organization’s needs and how to establish a successful cloud strategy. INTRODUCTION: DEFINING THE CLOUD I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description; and perhaps I could never succeed in intelligibly doing so. But I know it when I see it. ~ Hon. Potter Stewart (U.S. Supreme Court Justice) Why did Gartner Research place cloud computing at the top of the list of most important technology focus areas for the past three years...

...For Microsoft, the Nokia acquisition is worth it The news that Microsoft has acquired the Nokia’s handset business was received with mixed feelings. While some people believe that the acquisition will change the dynamics of the handset industry, others are of the opinion that the Microsoft's Nokia deal is actually smart but it has a very low chance of success. For these sets of people, even though Microsoft has been playing a role in the industry with their operating system, the software giant still doesn’t have what it takes to compete favorably in an industry seemingly dominated by Samsung, Apple and other emerging brands. No doubt, this is a strong argument by these sets of people, but what must not be taken away from the deal is that the $7.2 billion purchase of Nokia's devices business is probably the no-brainer acquisition of the year. In addition to shoring up Microsoft's most important smartphone partner, the buyout places into Microsoft's hands Nokia’s important technologies besides smartphones. Following the purchase, Microsoft has said that it aims to accelerate the growth of its share and profit in mobile devices through faster innovation, increased synergies, and unified branding and marketing. Hmm! This is surreal. Microsoft is not known for aggressive branding and advertising. Just maybe, this will help solves Microsoft's ultimate problem: making consumers and businesses want Windows Phones. Nokia is virtually the only smartphone vendor committed to Microsoft’s...

...Management Information Systems, 13E Laudon & Laudon Lecture Files by Barbara J. Ellestad Chapter 5 IT Infrastructure and Emerging Technologies As information becomes a valuable resource of a digital firm, the infrastructure used to care for it takes on added importance. We’ll examine all of the components that comprise today’s and tomorrow’s IT infrastructure and how best to manage it. 5.1 IT Infrastructure When you mention the phrase “information technology infrastructure,” most people immediately think of just hardware and software. However, there is more to it than just those two. In fact, the most important and often most-ignored component is that of services. Integrating all three components forces a business to think in terms of the value of the whole and not just the parts. Including all three components in any discussion of IT infrastructure truly fits the cliché that the whole is greater than the sum of its parts. Defining IT Infrastructure If you define a firm’s IT infrastructure in terms of technology you limit the discussion to the hardware and software components. By broadening the definition to that of service-based, you are then bringing into the discussion the services generated by the first two components. Also, you are including the persware element that we discussed in Chapter 1. As technology advances the types of hardware and software available, it becomes more critical for the firm to focus on the services that a firm can provide to its customers...

Abstract Ownership of mobile smartphones amongst the general consumer, professionals and students is growing exponentially. The potential for smartphones in education builds upon experience described in the extensive literature on mobile learning from the previous decade which suggests that the ubiquity, multi-functionality and connectivity of mobile devices offers a new and potentially powerful networked learning environment. This paper reports on a collaborative study conducted by an undergraduate student with the support of two members of academic staff. The research sought to establish the extent to which students are autonomously harnessing smartphone technology to support their learning and the nature of this use. Initial findings were explored through student interviews. The study found that students who own smartphones are largely unaware of their potential to support learning and, in general, do not install smartphone applications for that purpose. They are, however,...

...importance of BI systems and software to an organized corporate strategy and overall success. Reliable and accurate BI systems are used by many large corporations; they can be custom-built by a service provider or by people working for the corporation. This is because they are very expensive, cutting edge software systems. Past research has shown that BI is one of the fastest-growing methods of intelligence gathering in the field. With all of the attention of advances in information technology (IT) and how helpful they are it is easy to overlook some of their repercussions. This paper highlights the importance of BI in decision-making areas and the techniques used to make them. Advantages and benefits are then discussed and one major problem is described in detail. Computer hacking is becoming more popular as the future comes closer and it is a larger problem than most think outside of the business world. The conclusion offers an insight into the future of BI and identifies the problem of hacking as its major threat. 1. Introduction Business intelligence (BI) has become one of the most successful and popular ways that an organization uses to answer specific questions or problems over the past 25 years and is vital to success. BI is a term that covers a multitude of different concepts, theories, and methods that are related to data that has been kept in software designed for this specific purpose. The...

...McKinsey Global Institute May 2013 Disruptive technologies: Advances that will transform life, business, and the global economy The McKinsey Global Institute The McKinsey Global Institute (MGI), the business and economics research arm of McKinsey & Company, was established in 1990 to develop a deeper understanding of the evolving global economy. Our goal is to provide leaders in the commercial, public, and social sectors with the facts and insights on which to base management and policy decisions. MGI research combines the disciplines of economics and management, employing the analytical tools of economics with the insights of business leaders. Our “micro-to-macro” methodology examines microeconomic industry trends to better understand the broad macroeconomic forces affecting business strategy and public policy. MGI’s in-depth reports have covered more than 20 countries and 30 industries. Current research focuses on four themes: productivity and growth, the evolution of global financial markets, the economic impact of technology and innovation, and urbanization. Recent reports have assessed job creation, resource productivity, cities of the future, and the impact of the Internet. MGI is led by McKinsey & Company directors Richard Dobbs and James Manyika. Yougang Chen, Michael Chui, Susan Lund, and Jaana Remes serve as MGI principals. Project teams are led by a group of senior fellows and include consultants from McKinsey’s offices around the world. These teams draw...

...their article, “The Death of Advertising,” Roland Rust and Richard Oliver wrote, “the new media represent a vast ‘network of networks,’ now often referred to as the information superhighway. A technical reality, major parts of the information super highway are under construction all over the US (1994).” During the digital revolution of the last decade, modern humanity has experienced a shift in traditional media consumption habits, which is now culminating with mobile technology. In examining the emerging mobile landscape, two things are increasingly apparent. One, mobile technology is heading into uncharted territories. Two, this is happening at unprecedented rates. This landscape is so unpredictable that the introduction of a new highly viral application or technology could change the trajectory of mobile communications overnight and prove all existing data and projections obsolete. As such, some of the very current information offered in this report may be outdated a week from now. Many consumers are just beginning to adopt smartphones, which are any phones offering advanced capabilities with PC-like functionality and...

...1. INTRODUCTION TO MANAGEMENT INFORMATION SYSTEM Course Objectives: In any organization, small or big, a major portion of the time goes in data collection, processing, documenting and communicating it to the people. Hence, a major portion of the overheads go into this kind of unproductive work in the organization. Every individual in an organization is continuously looking for some information which is needed to perform his/her task. Hence, the information is people-oriented and it varies with the nature of the people in the organizationwhich is outlined in this courses. Benefits: * Management Information Systems - Concept * Management Process * Information Concepts * Development of Plans of the MIS * Database and Enterprise Management Systems INTRODUCTION TO MANAGEMENT INFORMATION SYSTEMS Management Information Systems - Concept The concept of the MIS has evolved over a period of time comprising many different facets of the organizational functions. MIS is necessity of all the organizations. The initial concept of MIS was to process data from the organization and present it in the form of reports as regular intervals. The system was largely capable of handling the data from collection to processing. It was more impersonal, requiring each individual to pick and choose the processed data and use it for his requirements. This concept was further modified when a distinction was made between data and information. The information is a product...
