Avoiding System Development Pitfalls in the IT Decision Making Dissertation

Avoiding System Development Pitfalls in the IT Decision Making Processes - Dissertation Example Likewise, a brief observation of these categorized characteristics of various applications, many categories have been projected. Sprague and Watson proposed the performance dimension of the systems can be categorized or can be divided in to four levels i.e. basic data processing systems, integrated data processing systems, management information systems and decision support systems (Hogue, 1985). However, the research and technology for the DSS continue to revolutionize and by 1996, Whinton and Holsapple proposed five particular types of DSS. These specialized DSS types were text-oriented DSS, database-oriented DSS, spread-sheet-oriented DSS, solver-oriented DSS, and rule-oriented DSS (Power,). Moreover, these last four DSS types were again divided into seven categories proposed by Arnott and Pervan (Burstein & Holsapple,). The seven categories are (Burstein & Holsapple,) personal DSS, group support systems, negotiation support systems, intelligent DSS, knowledge management-based DSS , executive information systems/business intelligence, and data warehousing. However, these sub categories overlaps with some of them but they introduced a diverse advancement of past research. Afterwards, these four levels were categorized as transaction processing systems (TPS), Management Information Systems (MIS) and Decision Support Systems (DSS). Information Technology has revolutionized. Business organization dependent on information systems, cater information for decision making. The revolutionized information technology completely modified the business structure and the information required for decision making process. A term called strategic management focuses on building a powerful competitive advantage. It also involves the development of corporate strategy along with the management of the organization according to that strategy (Strategic management.2007). The BRAC university has launched a world class Integrated library system (ILS) (BRAC university launches integrated library system koha dhaka, bangladesh — koha - open source ILS - integrated library system). It is â€Å"an interrelated group of computer programs that automates multiple library operations† (Ebenezer, 2002). The ILS will redefine customer services by advance information technology services that will enhance the process of delivering both electronic information and printed documents. Keeping in mind the long term perspective, the strategic goals for the ILS are constructed as: The infrastructure of the library will be enhanced and well maintained Maximizing the access to the customers for the printed information resources (not digital). Maximizing access to the customer of digital information resources. Establishing strategic affiliation with other libraries locally and globally including schools, colleges and universities. Build learning environments in all accessible locations connected with the library. The strategic goals are to define the library’s strate gic plan and as well as Information technology strategic plan. The current infrastructure has inadequate capacity, size and functionality which are not fulfilling user requirements. Current system has issues related to performance and functionality which is affecting the users. The system cannot be maintained as it needs to be re-designed. The decision for the replacement of the system was made because of

Therefore, for the process to be meaningful, it needs to employ different reliable stages of amplifications, as well as conversion. In order to attain these intensifications there are various number of means that one can use, some can be very simple while others can be perplexing (Van der Spuy, 2012). The findings will give a primary basis in the comprehension of various circuits as well as some major Analogue components. In addition, it will ensure there is the proper understanding of Proteus that is the computer simulation equipment. The principal intention of the research is to carry out the sampling process of a motor speed. The strategy of an amp is to be produced. The range of the current sample will have the following range. That is; from -2.5 to 2.5 m Amplifier. The initial step was to change the signal from that particular current to signal voltages that range from 2 – 3 Volts. The following step requires the filtration of the signal by employing a low pass filter and avoiding any signal that operates over 100 Hz. After the completion of this particular phase, there will be diversification of focus to the digital side of the circuit. There will also be the employment of an analogue converter that is the A 8 bit to change the current voltage signal into an eight-bit digital signal. There will also be processing of eight bit signal to give a two-bit indication in bit hex decimal on the two seven section showing devices that indicate the moving speed of that particular motor in 0-255 scales. In this particular section of the findings, the process indication as well as the workings calculations are all carried out together. The complete scheme has been subdivided into different
