...THE SYSTEMS DEVELOPMENT LIFE CYCLE LECTURE NOTES DEVELOPING INFORMATION SYSTEMS SOLUTIONS The Systems Development Cycle: The systems approach can be applied to the solution of many types of problems. When this involves the development of information system solutions to business problems, it is called information systems development or application development. Most computer-based information systems are conceived, designed, and implemented using some form of systematic development process. In this process, end users and information specialists design information systems based on an analysis of the information requirements of an organization. Thus, a major part of this process is known as systems analysis and design. When the systems approach is applied to the development of information system solutions, a multistep process or cycle emerges. This is frequently called the information systems development cycle, also known as the systems development life cycle (SDLC). Steps involved and products produced in the traditional information systems development cycle: 1. Systems investigation - Product: Feasibility Study 2. Systems analysis - Product: Functional Requirements 3. Systems design - Product: Systems Specifications 4. Systems implementation - Product: Operational System 5. Systems maintenance - Product: Improved System 1. All the activities involved are highly related and interdependent. 2. Several developmental activities can occur at the same time...

For the vast majority of you it will be a compulsory unit of study as it is part of the Business Core in all undergraduate Bachelor of Business degrees. The major focus of this unit is on how computer- based information systems can support decision making in organizations and businesses. Those decisions often need to be made by professionals who come from discipline areas you are studying such as accounting, management, information systems or marketing. One of the most important elements of an information system is people, so all of us need to know what role we can play and what role information and communication technologies (ICT) can play in supporting decisions. This unit will look at the theoretical side of information systems as well as personal productivity tools such as spread sheets and databases. In addition we will look at global trends in information systems and in particular the emerging use of Cloud Computing and Social Networking, which is sometimes called Web 2.0.

...given for this is globalization, highs information technology (IT) investments and the rapid pace of technological change. Organizations are responding in different ways and at different rates to the wide range of IT based opportunities and pressures. The purpose of this paper is to focus on the effects of IT related organizational changes on the management accounting function and to contribute to the body of knowledge about to what extent IT affects the ability to solve accounting tasks. The relationship between IT and accounting practices was investigated qualitatively using six case studies and we will measure the impact of IT on accountants’ tasks. The findings suggest a tendency for change and the decentralization of accounting tasks. Index Terms—Accounting, Accounting Information Systems, Financial Documents, Information Technology, Management Information System. I. INTRODUCTION Nowadays the business world is changing at a faster and faster pace. The reasons given for this is globalization, highs IT investments and the rapid pace of technological change in combination with escalating costs of research and development (Frishamar, 2002). The role of information technology (IT) has shifted over the last decades (Teng & Calhoun, 1996) to become an important part of how companies manage and control their resources.

The paper discusses the limitations of the case study design for theory building and explains how grounded theory systemic process adds to the case study design. The author reflects upon his experience in conducting research on the articulation of both traditional social networks and new virtual networks in six rural communities in Peru, using both case study design and grounded theory in a combined fashion in order to discover an emergent theory. Key Words: Case Study, Interpretive Approach, Theory Building, and Grounded Theory Introduction Researchers adopting a case study design face a number of challenges in making their argument. Yin (2003) himself warns researchers who adopt a case study design to be conscious that their findings will be challenged and prefaces his book enumerating the alleged weaknesses in the case study; a methodology that downgrades the academic disciplines and lacks sufficient precision, objectivity, and rigour. We should note that those warnings come from an author who operates from...

...Convergent Idea Generation in Teams: A Comparison of Computer-Mediated and Face-to-Face Communication DAVID S. KERR Department of Accounting, Mays School of Business, Texas A&M University, College Station, TX 77843-4353, USA (E-mail: d-kerr@tamu.edu) UDAY S. MURTHY School of Accountancy, University of South Florida, 4202 E. Fowler Avenue BSN3403, Tampa, FL 33620-5500, USA (E-mail: umurthy@coba.usf.edu) Abstract Many tasks and decisions in business, including management consulting, are performed in group settings. Computer-mediated communication (CMC) tools (e.g., Lotus Notes) are increasingly being used by businesses to support teams in a variety of settings. Considerable research in information systems has demonstrated the advantages of “electronic brainstorming” (EBS) for generic tasks involving only divergent thinking. However, it is unclear whether the benefits of CMC extend to tasks that require both divergent and convergent processes. Per task–technology fit theory (TTF) (Zigurs and Buckland 1998), the use of computer-based group communication support tools, including “chat” systems in wide-spread use today, may be less effective for convergent processes than for divergent processes. This study experimentally compares the performance of computer-mediated and face-to-face (FTF) teams on tasks requiring both divergent and convergent processes. Consistent with theoretical predictions, the results revealed that computer-mediated teams outperformed FTF teams in the divergent...

...INTRODUCTION Rationale of the Study Acquiring information is quasi difficult. Specifically, information that was secluded from general views. To puzzle out this problem, technology becomes an absolute must. In fact it can be used effectively in daily lives. The most essential contribution of technology to society is making the lives of people much easier and helping them achieve more what was previously impossible. The discovery of computers was the great function of modernity to make work easier, faster, and more precise for the humanity. Though technology may differ in various ways, but its uses are likely more advantageous. With technology, people find fast acquisition and availability of information. To have lived in this world for so many years without the use of computers just seem unthinkable or even unbelievable! (Stair and Reynolds, 2007). In today’s generation of rapid development, technology facilitates peoples’ lives and creates more comfort. It has remarkably improved the quality of life. Due to this transitory advancement, youngsters resort on finding information the easiest and most convenient way. It is in this era also that technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advanced economies. As organizations and entrepreneurs continue to operate in an increasingly competitive and global market place, workers in all business areas including information system, research and development...
