Management Information System to Organisations Essay

Management education system is essential for creating competitive firms, managing planetary corporations, and providing useful products and services to customers. (Laudon, 2002,P1) It provides knowledge figure of reports and displays to managers. For example, sales managers may use their computer workstations to get sales results of their products and to access weekly sales analysis reports, and thus evaluate sales made by each salesperson. Management selective data systems arose in the 1970s to focus on computer-based information systems aimed at managers. (Laudon, 2002, P15). Because of the growths of the Internet, globalisations of trade, and the rise of information economies, have to improve the role of information systems in business and management.And then it strikes pays attention to organisation management information that issues raised by sociology, economics, surroundings and psychology. An organization is a stable, formal social structure that takes re book of fact ss from the environment and processes them to produce outputs. (Laudon, 2002,P87) This essay will be evaluating the contribution of Management Information form to Organisations. ilk as What relationship between information and managers job computer networks importance for management information phylogenesis unalike types of management information systems to use differences and how it is impact and limitation of information systems.Firstly, before organisation Management Information requisite to understand it that have four factors teach the usefulness of information a manager caliber, metreliness, fill inness, and relevance (G beth, 2000,P613)Accuracy and reliability determine the quality of information. (G atomic number 18th, 2000,P613) tell us higher quality of information need have greater accuracy and reliability. The greater accuracy and reliabilitys information will bring correct decision for manager. For example, accounting informstions, information as accuracy refe rs to the extent to which information effectively represents a situation as it really is, the accuracy of each source of data used varied widely.((Volking, 1993, P8)The source where accuracy posed the greatest problem was the marketing database.So I think usefulness informations need have accuracy andreliability, accuracy and reliability determine the quality of information.Information that is timely is available when it is needed for managerial action, not after the decision has been made (G atomic number 18th, 2000,P614) In todays speedily changing valet and technology s developing, lead to information changing frequently. Real-time Information is reflecting current conditions. (Gareth, 2000,P614) For example, productions price changing frequently in marketing because manager wants to practice profit in competitions marketing. So manager should be pay attention to informations changing. Catch Real-time information is truly importance. Look at timeliness in accountingTimeliness accounting information should be made available to external decision-makers before it loses its capacity to becharm decisions. (Dyckman, 1992, P44) Like the news of the world, old financial information never carries the same impact fresh information carries. Otherwise lack of timeliness reduces relevance.Information that is complete gives managers all the information they need to exercise figure, achieve coordination, or make an effective decision. (Gareth, 2000,P615) informations completive will provided good help to manager to decision. When you deal up a new business, look at complete information is importance. Such as, how is this productions sold, how long can make profit and how much capital need put in this company at first time. Also information in accounting system as well need pay attenation to informations completetive.Information that is applicable is useful and suits a managers particular needs and circumstances (Gareth, 2000,P615) It can make a difference in a us ers decision. Relevance refers to the capacity of accounting information to make different to external decision-makers who use financial reports. They use accounting information with every or both of two viewpoints in mindForecasting what the economic future is likely to hold.Confirming the accuracy of past forecasts.Stated more technically, relevant accounting information help users to make predictions about future events, to confirm or correct prior expectations, and to evaluate current conditions. (Dyckman, 1992, P43)In my opinion, relevant is near importance, because if the data are not relevant to the task at hand, manager will be make mistake by these wrong information, and west time in wrong decisions. And then will bring some problem for this company s operation.Information decision, control and coordinationSecondly, information technologys nurture is importance for management information development. Because the growths of the Internet, globalisations of trade, and the ri se of information economies, it have to improve the role of information systems in business and management. Software is the detailed instructions that control the operation of a computer system. Without software, computer hardware could not perform the tasks we associate with computers. The functions of software are to (1) manage the computer resources of the organisation (2) provide tools for adult male beings to take advantage of these resources, and (3) act as an intermediary between organisations and stored information. Selecting suitable software for the organisation is a key management decision. (Laudon, 2002,P172)Thirdly, different types of management information systems to use differences a transaction-processing system is a system designed to handle large volumes of routine, recurring transactions. (Gareth, 2000,P625) For example, managers use transaction- processing system to record sale of items and running inventory levels, employee record keeping, and payroll.A manage ment information system that gathers, organize, and summarizes comprehensive data in a from that managers can use in their nonroutine coordinating, controlling, and decision-making task.(Gareth, 2000,P626) Operational placements are concerned with transaction handling and theday-to-day operation of the organisation, usually for a particular department within the organisation. Data are entered and stored in a appoint format, and are updated regularly during routine processing. Example, Producing invoices and monthly reports for operational-level managers, and fortnightly payroll cheques.The major disadvantage of this system is that they are inflexible and so not able to be adapted easily to do new tasks, or expected tasks earlier than usual. They also do not support any decision-making advice ability for tactical and strategic-level managers. nigh companies today have gone beyond this system. (Long, 1994,P365-397)Decision support systems give direct computer support to managers dur ing the decision-making process. For example advertising managers may use an electronic database packs up to do what, if analysis as they test the impact of other advertising budgets on the forecasted sales of new products. (OBrien, 1997,P31) A Decision Support System is an interactive information system that rely on integrated user-friendly hardware and software designed to assist mangers make decisions related to the efficient and lucrative running of the business.Expert systems can provide expert advice for operational chores like equipment diagnostics, or managerial decisions such as loan portfolio management. (OBrien, 1997,P32) Expert systems have been unquestionable for subjects such as medical diagnosis, oil exploration, financial planning, taxation return preparation, chemical analysis, surgery, weather prediction, computer repair, nuclear power plant operation, newspaper layout, understand government regulation, and troubleshooting computer systems configurations (eg. MS Help). (Long, 1994,P365-397)Finally, management information systems also have some limitations and some technology impact its development. The advance in management information system and technology are having important effects on managers and organisations. (Gareth, 2000,P629) One of the most important of theseinvolves the subjectivity of the scoring technique. Clearly establishing the extent to which a data attribute is inherent in any one data source is highly judgemental. Likewise, establishing weightings for each attribute is also a highly subjective process. These tasks are therefore very much subject to the perception of the individuals who carry them out. This problem could be partly overcome by increasing the objectivity with which such estimates are made.Conclusion, Management information system is an information system that managers plan and design to provide themselves with the specific information they need.
