¶ … Decision Analysis System
Computers have brought a great change in our lives. A software program called spreadsheet turns the computer screen into a paper sheet one is working on. This program saves time by reducing the errors and repetitions of calculations. It is commonly used in physics labs in order to save time by getting accurate results and accumulating proper data in labs. Spreadsheets have traditionally been used by accountants for the purpose of bookkeeping and budgeting, when actually they can prove to be amazing tools for engineers and scientists as well. Using a spreadsheet, entered raw data could be manipulated and plotted through few easy commands. Furthermore, due to their built-in capability to easily plot data, spreadsheets prove to be especially useful (Karmakar et al., 2007).
Initially introduced in the corporate world in late 1970s and the early 1980s, it proved to be an immediate success. The usefulness, power of spreadsheets, and adaptability helped ignite broad-based approval and adoption of desktop computers in businesses. In today's world, electronic spreadsheets have become ubiquitous, and there are plenty of reasons why (Karmakar et al., 2007).
Spreadsheets have become indispensable tools for everyone involved in doing financial calculations and modelling. Around 92% of public companies utilize spreadsheets for all critical financial accounting activities, according to a recent article on accountingWEB.com. Usage of these spreadsheets range from revenue accounting to revenue scheduling, redistribution and allocation (Karmakar et al., 2007). The paper highlights that spreadsheets have been widely used due to the fact that plenty of the key revenue identification and reporting tasks are not completely automated in today's business systems.
The capabilities of spreadsheets which include conditional statements, programming through macros and calculations make them experts in creating all sorts of ad hoc applications. Moreover, these can be utilized in many areas including budgeting, inventory control, financial modelling, reporting and data entry of all the financial information (Karmakar et al., 2007).
Paradoxically, what actually makes a spreadsheet highly attractive proves to be one of its shortcomings. Companies need to balance ease-of-access, flexibility and procurement cost of using spreadsheets vs. their shortcomings in being used at the enterprise-level. These shortcomings can be classified in the following three areas (Karmakar et al., 2007):
having a lack of data integrity, as values might be changed on purpose or accidentally being error prone, resulting from errors occurring during input, logic, or data interface and use not being proportional with standard IT regimes as a tool for running highly critical applications such as documentation, version control and testing
Spreadsheets are important tool of data analysis that is used in decision making. However, it is important to mention that spreadsheets cannot perform the complete analysis required for decision making hence reliance on them only leads to high risk that decision making will be wrong and may lead to loss in business (Karmakar et al., 2007).
Despite all the shortcomings, spreadsheets are used at vast level. All the organisations cannot afford or manage to develop a customised application that can replace spreadsheets in business operations. There is an important need to focus on utility of spreadsheet in the organisation and its likely shortcomings so that organisations can devise better plan for those functions which are not performed by spreadsheets. Furthermore, there are many functions which are perfectly performed by spreadsheets and are prone to high degree of error if performed manually. This is one of the reasons; organisations do not quit using spreadsheets (Karmakar et al., 2007).
Risks inherent in usage of spreadsheets
The errors contained in spreadsheets are noted at broad industry level. In July 2002, The Journal of Property Management published a report stating that 30 to 90% spreadsheets are erroneous and errors are likely to be significant from decision making point-of-view. In May 2004, similar information was presented by a Computer World article stating that 91% of spreadsheets used in decision making were erroneous (as cited in Ragsdale, 2008).
The errors are significant and industry cannot ignore them. The errors are leading to huge misleading information. Mentioned below are few examples (Ragsdale, 2008).
• Ad hoc process was mistakenly shown with the figure of $644M;
• The total of spreadsheet errors results in the figure of $30M;
• A faulty spreadsheet has projected the error of $11 million;
• $118,387 was the outcome of erroneous data entry (Ragsdale, 2008).
Several factors determine the range and magnitude of errors. Simple errors might occur in coding of macros and spreadsheet formulas. They are also referred at times as simple user error, which are immensely basic, such as the function of copy and paste. The probability...
Decision Support System (DSS) Assuring a safe and secure it (IT) atmosphere for that exchange of business has been a significant problem. The degree related to the task has been increasing annually, as assailants become a little more well-informed, more driven, and more vivid within their endeavours. Based on a lead security professional at International Data Corporation, a worldwide supplier of marketplace data and advisory services to the IT network, "Rising
Clinical Decision Support Systems: Decision support systems were first developed and implemented in the corporate world in order to support business management. In the past few years, these support systems have been integrated into health care organizations to provide a sharpened evaluation capacity to data warehousing and data mining. The refined data analysis ability can result in enhanced patient care and diagnoses through assessment of several symptoms, forecasting of some drug
System Design: Oahu Base Area Network The aim of this paper is to examine and discuss the Navy's decision to build the largest local area network (LAN) connecting the U.S. Pacific Fleet using information-gathering techniques and design methods. The system has the capacity to connect sailors and marines within the 102-million square miles of the Pacific Fleet's command coverage. Moreover it will provide the indispensable access for supplying and training the
Decision Sciences Decision-making is an important activity for top management in any enterprise. Strategic thinking is required for making useful decisions. For example, business executives plan strategies to access market share, to deal with employees, to react to competition and to decide on career growth. Decision Sciences is a discipline on its own that provides techniques and methods to take decisions in any practical situations. In this paper, a list of
Third, subsystems engineers are more attuned to how their specific product and technology areas are driven by external market forces and market dynamics than system engineers typically are. The reason is that subsystem engineers, both hardware and software, seek to understand how customer and market needs impact their existing and future designs. As both of these classes of subsystem engineers are more focused on how to create valuable contributions
To some users of personal computers, who state, never trust a computer that you cannot lift; the IBM has been viewed, more often than not, as an enemy, and according to Byte, the computer magazine, this was because of the fact that the IBM company rose to fame mainly on the basis of its mainframe computers, that were large and forbidding, and overwhelmingly bulky. This was probably why, when
