Major Systems used in an Organization Essay

Organizations utilize unlike types of study systems to take their personal credit line decisions for their operations. The hierarchy takes of the nerves in general argon operational, knowledge, management, and strategic. Accordingly, three main(prenominal) categories of selective education systems administer at different organisational take aims on hierarchy beI. Operational-level systemsII. forethought-level systemsIII. Strategic-level systems1. Operational-level systems reading systems that monitors and maintain operational managers, keeping track of the elementary activities and championship transactions of the organization.E.g.Sales,receipts,cashdeposits, pay roll, credit decisions and flow of materials in a factory.2. Management-level systems Information systems that sets the observe, controlling, decision-making, and administrative activities of middle managers of the communication channel organization3. Strategic-level systems Information systems that fill -in the long-range planning activities of precedential management and booster senior management carriage and address strategic issues to keep the strategic growth of the course family. study types entropy systems in organizations include1. Transaction touch on Systems (TPS)2. Management Information Systems (MIS)3. Decision-Support Systems (DSS)4. Executive Support Systems (ESS)Transaction performanceing systems plump at the operational level of organization. Knowledge work systems help bring about and integrate new knowledge within the organization. Management breeding systems return managers with reports based primarily on info pulled from transaction treat systems, nurse an internal predilection, and pay limited flexibility. . Decision-support systems function at the management level and proffer uninflectedal models and entropy analysis tools to provide support for riggingstructured and unstructured decision-making activities. Executive support systems funct ion at the strategic level, support unstructured decision making, and rehearse advanced graphics and communications. study types information system in a exemplary organization is shown in below insert along with strategic levels and working(a) beas.Transaction adjoining was nonp argonil of the first crease processes to be com bordererized and without information systems, recording and impact business transactions would consume huge amounts of an organizations resources. legal proceeding are as yetts that occur as part of doing business, such(prenominal) as sales, purchases, deposits, withdrawals, refunds, and payments. TPS serve the operational level.The transaction processing systems (TPS) is a computerized system that performs and records the daily quotidian transactions indispensable to the persuade of the business. TPS excessively involve employees in business processes. Transaction Processing Systems are information systems that process data resulting from the incident of business transaction. Every organization has manual and automated transacting processing systems (TPSs), which process the detailed data prerequisite to update records about the fundamental business operations of the organization. These systems include tramp entry, inventory control, payrolls, accounts payable, accounts receivable, and general ledgers to name a few.The input to these systems includes basic business transactions such as client orders, purchase orders, receipts, time records, invoices and customer payments. The result of processing business transactions is that the organizations records are updated to reflect the consideration of the operation at the time of the sustain process transaction. Automated TPSs consist of all the components of Computer Based Information, including databases, telecommunications, people, procedure, software program and hardware devices implementd to process transactions. The processing activities include data collection, data edit, data correction, data manipulation, data storage and document production.The transaction processing systems (TPS) is a computerized system that performs and records the daily piece transactions necessary to theconduct of the business. TPS also involve employees in business processes. Transaction Processing Systems are information systems that process data resulting from the occurrence of business transaction. Every organization has manual and automated transacting processing systems (TPSs), which process the detailed data necessary to update records about the fundamental business operations of the organization. These systems include order entry, inventory control, payrolls, accounts payable, accounts receivable, and general ledgers to name a few. The input to these systems includes basic business transactions such as customer orders, purchase orders, receipts, time records, invoices and customer payments.The result of processing business transactions is that the organiza tions records are updated to reflect the status of the operation at the time of the last process transaction. Automated TPSs consist of all the components of Computer Based Information, including databases, telecommunications, people, procedure, software and hardware devices engagementd to process transactions. The processing activities include data collection, data edit, data correction, data manipulation, data storage and document production.Management Information Systems (MIS)BASIC CONCEPTSFive resources are 1. Men 2. Machine 3.Materials 4. Money 5.Methods. Information is considered as sixth resourcesManagement information system (MIS) is an organized collection of people, procedures, software, databases and devices used to provide routine information to the managers and decision makers. The focus of an MIS is primarily an operational efficiency, foodstuffing, production, finance and otherwise functional areas are supported by MIS and linked through a common data base.Manageme nt is a process consisting of planning, organizing, to achieve organizational objectives.MIS is vital in any organization for two reasons1. It emphasizes the management orientation of IT in business ( non merely the processing of data).2. It emphasizes that a systems framework should be used for information systems applications.Various functions of management are briefly define as follows 1. Planning process of deciding in advance the grow of action 2. Organizing forming formal group of people and activities to facilitate achieving its objectives3. Controlling checking the patterned advance of plans and correcting any deviations 4. Directing processing of activating the plans, structure and group efforts in the desired direction.MIS supports the management level by providing routine thick reports and ejection reports for various purposes of management control process, including planning, controlling, and decision making.Examples are sales and improvement per customer and p er region, relocation summary and analysis, inventory control, capital investment analysis, and even a report on students who were here in the autumn merely did not to return in the spring.2.6 Decision Support SystemDecision-support systems provide material for analysis for the solution of semi-structured occupations, which often are unique or rapidly changing. Typically, they provide the ability to do what if analysis. DSS will often use data from away sources, as well as data from TPS and MIS. DSS supports accountability now analysis rather than the long-term structured analysis of MIS. DSS are designed for analytical purposes and are flexible in nature. DSS provide civilise analytical models and data analysis tools to support semi-structured and unstructured decision-making activities. DSS use data from TPS, MIS, and external sources, provide more analytical power than other systems and interactive. The trespass is on decisions in which there is sufficient structure for comp uter and analytic aids to be of value but where managers concept is essential. A DSS is an organized collection of people, procedures, software databases and devices, used to support problem/specific decision making and lead to problem solving. The focus of a DSS is on decision making effectiveness when faced with unstructured or semistructured business problems.2.61 Characteristics of decision support systemThe main characteristics of DSS are1. DSS help managers make decisions that are semi-structured, unique, or rapidly changing, and not easily specified in advance.2. DSS are responsive enough to mesh several times a day in order to add to changing conditions. 3 DSS make use of both internal information (from TPS and MIS) and also from external sources, such as current stock prices or product prices of competitors. 4 DSS offer exploiters flexibility, adaptability, and a quick response. 5 DSS kick users to initiate and control the input and output. 6 DSS operate with little or no assistance from professional programmers. 7 DSS provide support for decisions and problems whose solutions cannot be specified in advance. 8 DSS use sophisticated analysis and modelling tools.9 DSS shall support the manager but not re rate his/her appraisal. It should accordingly neither try to provide the answers nor impose a predetermined or predefined sequence of analysis. 10 DSS requires the decision makers insight and judgment to control the process and solution.2.63 Examples of DSS SystemsAirlinesPrice and route selection, flight scheduling investing CompaniesInvestment evaluationRailwaysTrain Dispatching and RoutingFrito-Lay, Inc.Price, ad and promotional sectionManufacturing doing optimisationOil CompaniesEvaluation of potential drilling sitesExecutive support systems (ESS)/ Executive Information System (EIS) Senior managers use ESS to make decisions, ESS serve the strategic level of organization. They address non-routine decisions requiring judgment, evaluation and i nsight because there is no agreed on procedure for arriving at a solution. Executive support systems function at the strategic level, support unstructured decision making, and use advanced graphics and communications. Examples of executive support systems include sales way forecasting, budget forecasting, and personnel planning. ESS is designed to incorporate data about external events such as new tax laws or competitors, but they also draw summarized information from internal MIS and DSS. They filter, compress and track critical data, emphasise he reduction of time and effort required to obtain information useful to executives.ESS employ roughly advanced graphics S/W and can deliver graphs and data from many sources immediately to a senior executive force. ESS combines many features of MIS and DSS and Provide top executives with immediate and indulgent addition to information. ESS help to Identify factors that are critical to accomplishing strategic objectives (critical succe ss factors) and therefrom provide a generalized computing and communications environment that help senior managers address strategic issues and identify long-term trends in the firm and its environment. ESS addresses non-routine decisions requiring judgment, evaluation, and insight because there is no agreed-on procedure for arriving at a solution. ESS preface graphs and data from many internal and external sources through an interface that is easy for senior managers to use. Information presented in forms tailored to the preferences of the executives using the system. ESS provides out put as desired by the end-user in the forms like Customizable graphical user interfaces, Exception reports, Trend analysis etc.,2.74 Features of ESS1. Contemporary ESS bring together data from all parts of the firm and enable managers to select, access, and tailor them as required using easy-to-use desktop analytical tools and online data displays. 2. Through their ESS, many managers ready access to public data, such as news services,financial market databases, and economic information. 3. ESS has the ability to drill down, moving from a piece of summary data to lower and lower levels of detail. 4. Contemporary ESS includes tools for modeling and analysis. 5. Whereas DSS use such tools primarily for modeling and analysis in a fairly concentrate range of decision situations, ESS use them primarily to provide status information about organizational performance. 6. Well-designed ESS also have some facility for environmental scanning. 7. A key information requirement of managers at the strategic level is the ability to detect signals of problems in the organizational environment that indicate strategic threats and opportunities. 8. Ability to analyze, compares, and highlight trends.9. The easy use of graphics enables the user to get word at more data in less time with greater clarity and insight than paper-based systems provide. 10. The timeliness and availability of the data result in needed actions being identified and carried out earlier than previously could have been done 11. Problems are handled before they become too damaging opportunities are also identified earlier. 12. Immediate access to so much data also enables executives to better monitor activities of lower units reporting to them. That very monitoring ability enables decision making to be decentralized and to take place at lower operating levels.2.76 Interrelationships among systemsIn contemporary digital firms, the different types of systems are closely linked to one another. This is the ideal. In traditional firms these systems lam to be isolated from one another, and information does not flow seamlessly from one end of the organization to the other. Efficiency and business value tend to capture greatly in these traditional firms. The interrelation ship between major kinds of system in an organization is depicted in below figure .The various types of systems in the organization exchan ge data with one another. TPS are a major source of data for other systems, especially MIS and DSS. TPS are operational-level systems that collect transaction data. Examples of these are payroll or order processing that track the flow of thedaily routine transactions that are necessary to conduct business. TPS provide data that are required by office systems, KWS, MIS and DSS, although these systems may also use other data. KWS and office systems not scarcely use data from TPS but also from MIS. DSS not only use data from TPS but also from KWS, office systems, and MIS. MIS rely heavily on data from TPS but also use data from KWS and office systems. ESS obtains most of their internal data from MIS and DSS.
