Özet
Bu çalışmada, yönetim bilişim sistemleri ve bu sistemlerin yönetime olan katkısı incelenmeye çalışılmıştır. Bu amaçla birinci bölüm, yönetim ve sistem kavramlarının açıklığa kavuşturulmasına ayrılmıştır. Yöneticinin sistem teorisinden yararlanma ve organizasyonun bütünleştirilmesinde sistem yaklaşımını uygulamak zorunluluğu mevcut bilişim sistemlerinin büyük olasılıkla yeniden tasarlanmalarını gerektirmektedir. ikinci bölümde, öncelikle yönetim bilişim sistemlerinde odak noktası olan“bilgi”ve“veri”kavram ele alınmış ve daha sonra yönetim bilişim sistemi tanımına geçilmiştir. Yine bu bölümde YBS öğeleri, temel unsurları, işletme içinde fonksiyonu ve işletmedeki bilişim düzeyleri açıklanmaya çalışılmıştır. üçüncü bölümde ise YBS organizasyonda tasarlanması, uygulanması ve değerlendirilmesi aşamaları belirtilmiştir. Genel tasarım felsefesi üzerinde durularak, başarılı sistem geliştirilmek için organizasyonda bulunması gerekli koşullar belirtilmiştir. Dördüncü bölümde temel ve alt bilişim sistemlerinin tanımı yapılmış ve ayrı ayrı incelenmiştir. Beşinci bölümde, orta ölçekli bir sanayi kuruluşu tanıtılarak, yönetim bilişim sistemi kurulması aşamaları anlatılmıştır. Yöneticilerin bilgi ihtiyacının yeterli, doğru ve zamanında karşılamamanın ortaya çıkardığı aksaklıkların bertaraf edilmesi şarttır. Bu nedenle yönetim bilişim sisteminin uygulanması kaçınılmazdır. Firmada bu eksiklikten yola çıkılarak hazırlanan bu çalışma kısmen faaliyete girmiş durumdadır. <vii i)
Özet (Çeviri)
Involvement in the effective design and use of computer- based information systems is essential for the managers. To be most effective systems must be designed for the requirements of the managers-user- Too off there is a communication gap between managers who are too busy uninterested or unwilling to become directly involved on the one har, and on the other, the consultant who is more usually engrossed in the special nature of the system. Objective of the work is to explain what management information systems are, and how to establish of a management information system. The first chapter gives definition about management and system concipts. Managers must get help from system theory and use system approach to gather organisations. After that they will feel they must review existing management information system and also to plan new management information system. The second chapter explains“information”and“data”terms which are most important terms in management information systems. Then management information systems definition is given. In organisations all departmens required comminicat ion to achieve their functions. So management need information. In thes chapter, which information is required by management is examined. System concept means that all elements in system are involved and communicate each other. For this reason communication is needed for lasting system approach and to keep existing of management information system. If information which is provided other original can not be given to the manager, he will not be able to make decision easily. Computers a're not essential for management information systems but they can be very useful. The <ix)study of management information systems is not about the use of computers it is about the provision and use of information relevant to the user. Computers are one means of. produciny information and concentration on the means of production rather than the needs of the user can lead to expensive mistakes. There is undoubtedly an important and growing role for computers and information technology in management information systems but the technology must be used with discretion. Computers are good at rapid and accurate calculations, manipulation, storage and retrieval but less good at unexpected or qualitative work or where genuine judgement is required. It has been suggested that computers can be used to best advantage for processing information. After that for comparison with management information system, data processing systems ar^e explain and some terms about data processing e.g. data management databank, database, data processing methods are defined. Management information system contact all these functions and others which is given in this chapter. Managers information system objective is to help close the communication gap that seperates the manager from the consultant. For this reason information which is required for management must be given right persons, at the right time. System approach in management thinks organisation as a whole. It provides information flow between decision and operation centers. Information is required for management and decision making, and management information system record, keep and send to the information which is required for decision making. There are few aspects of life nowadays which are unaffected by information technology. In the office, factory or at home, visiting a bank, supermarket or garage and in many other places information technology is used to carry out transactions, provide information, record data, make decision and perform an ever increasing range of tasks. Also, in this chapter, elements, functions of management information system and information levels is examined. It is explained that how management information system influences management, planning, control and decision making functions. <x)The term MIS has become almest synonymous with computer based data processing and indeed many books with MIS in the title turn out to be exclusively concerned with topics such as systems analysis, file design and the various other technical facets of computer based systems. This emphasis results in a production orientated definition of MIS of which the following by Kelly is a typical example :“Management information system : The combination of human and computer-based resources that results in the collection, storage, retrieval, communication and use of data for the purpose of efficient management of operations and for business planning.”MIS have decision facus, that is, their rationale is to improve decision making. This cannot be done unless the manager is intimately invalved with the selection of issues and problems the system addresses, the information content of reports and files, the nature of the models used, the structure of any automatec decision making and dividing line between programmed and non-programmed decision making. In many practical sitvations the manager is the main source of data. Itc knows the problem and has been given the responsibility to solve it. According he must play a key role in devising a system which will help to general a solution. This not only ensures the validity and practica nature of the system but will also increase the manager' s conf idance in it. The design of many planning and control information systems requires management participation at several levels in the organisation. Both senior and subordinate management must agree on what factors are to be controlled, how performance will be.judged, what are realistic reporting periods and so on before any information system can be designed. Business becoming more and more complex. Management information system is effective method for achieve management functions in complex organization by using system approach. One of the major factures of the systems approach to solving organisational problems is that it is objective orientated. It does not start from a detailed analysis of the workings of particular ports of the system. This latter approach tends to produce solutions which find Cxi)better ways of organising unnecessary activities or cheaper ways of producing unwanted products. The systems approach concentrates first of all on defining the correct objectives before can templating how they are to be achieved. This is clearly a superior phi losophy. To avoid major errors of sub- optumusat ion it is vital to consider and define overall organisational objectives before establishing the objectives of the part of the system being studied. The senior systems in the hierarchy of systems should make clear, unambiguous statements of what the junior sub- systems are expected to contribute. Overall objective getting is a primary task of strategic management. In the next chapters establish of a management information systems are examined. Management information system couldnit be designed and establish at once. This system will develop by the time, for this reason to design, to establish ahd to process function should done that all parts can work seperately and together. In this chapter also is explained required conditions for developing succesful system given design steps. Despite rules about design steps, conditions for development, for management information system design can not be given solid, unchangeable rules. First of all limits and needs of organizations are determined, and new management information system is established. But design steps can be changed. There are numeraus factors which influenge the structure and scope of an organisation's MIS : The primary function of the organisation - Is it manufacturing ar service company, a wholesaler, a local authority, a public utility, a hospital? fire there numerous functions? What linkages exist between them? Are they complementary or disporate? What type of technology is used? The structure and levels of the organisation. Is tl organisation composed of numerous sections and levels? What degree of autonomy have the section / departments? (xii)The degree of centralisation or decentralisation: Is the, organisation tightly controlled at the centre. What decisions / actions are the sections allowed to take? What is committee structure? Interaction with enviranment. To what extent is external information of importance? In what ways daes the organisation need to communicate with its environment - to customers, suppliers, trade unons, government departments etc? What is the legislative framework? What decisions need to be taken. What is the extent of programmed and non-programmed decision making? What levels take the decisions? What is urgency surrounding the decision making process? What is the time scale of decisions? The scale of operation. How many employees? How many branches / departments / sections? What is the volume of orders invoices, bill, enquiries, transactions etc? The management style. Is it an authoritarion or participative style? Are procedures and operations routine and closely prescribed? Is management by exception practise? What is the control structure? Use of information technology. What is the extent and type of information technology usage? What degree of expertise exists throughout the organisat ion-not just the information technology specialists? What is the availability of equipment? To what extent is planning formalised? What time scales are involved? What is the extent of participation in planning? Hoi is planning monitored? How are plans implemented? The introduction of any new system brings change and it seems to be a common human reaction to resist change until, of course, it can be shown to be an individual's advantage. Adverse from people upon the ^introduction of a computer based data prosessing system can arise from various factors, typical of which are the following ı (xiii)- Fear redundancy - Fear of reduction in status.job satisfaction - Fear of changes in the organisation and departmental boundarious affecting promotion prospects, differentials etc. - People's aims and ambitions threatened. - Proposals seen as criticism of past efforts. - Distrust of systems personnel and computers etc. There is no one single action which can eliminate resentment and mistrust. The system designers must bear this human factor, which is crucial, in mind at all stages. Typical ways in which such problems can be minimised or eliminated are as follows : - Set out to involve the personnel concerned from the beginning - Invite personnel to contribute actively to the project by making suggestions which should be freely and publicly acknowledged. - Institute comprehensive training and retraining schemes. - Encourage co-operation. - Demonstrate that the elimination of some routine work will improve.job satisfaction. - Ensure that full top management support and backing is received and clear statements publicised regarding.job security, prospects, pay etc. - Above all, comminucate fully and frankly with those affected. In fourth chapter, basic and sub- systems are defined, find examples about this information systems are given. In the last chapter, a study in real organization is given. Establishment of a management information system is examined step by step. (xiv)
