1. Management-oriented decision-making: This system is an important development after the thinking method of management and the behavior theory of management decision-making, and supports management and regulation through quantitative methods, forecasting and plan optimization. In order to serve management decision-making, we must be able to provide the required information in time according to the needs of management to help decision makers make decisions. ?
2. comprehensiveness, intersection and marginality: MIS is a comprehensive system for overall management of organizations. It is embodied in three aspects: interdisciplinary, multi-talented, and integration of software and hardware. ?
3. Prediction and control ability: Use mathematical models, such as operational research model and mathematical statistics model, to analyze data and information, so as to predict the future and provide decision support.
4. Man-machine system: organs and machines account for the majority, but people are always the main body of management system construction, involving many personnel groups. Therefore, the management information system is also a man-machine combination system.
Managers at all levels are both users and components of the system. Therefore, in the development process, according to this feature, we should correctly define the position and role of people and computers in the system, give full play to their respective strengths, and make the overall performance of the system optimal.
The main functions of the system include: project development management, task management, bidding business management, cost consulting business management, engineering consulting business management, import agency business management, contract management, financial management, file management, statistical reports, online project registration, Party A's function management, office automation and system setup.
Extended data:
The function and background of management information system;
1. Management information is an important resource
For enterprises, people, things, energy, capital and information are five important resources. People, materials, energy and capital are all visible tangible resources, while information is intangible resources. In the past, people paid more attention to tangible resources. After entering the era of information society and knowledge economy, information resources have become more and more important.
Because information resources determine how to use material resources more effectively. Information resources are the crystallization of knowledge acquired by human beings in their struggle with nature. Mastering information resources can make better use of tangible resources and make tangible resources play a better role.
2. Management information is the basis of decision-making.
Decision-making is to make correct judgments and decisions by understanding the objective situation, external situation, external situation and internal situation of the enterprise. Therefore, decision-making and information are closely related. In the past, some decisions based on experience or slapping one's head often led to decision-making mistakes, and it became more and more clear that information was the basis of decision-making.
3. Management information is the basis of implementing management control.
In management control, information is used to control the operation of the whole production process and service process, and the existing plan is constantly revised through information feedback, and management control is implemented through information. There are many things that can't be well controlled, and the root cause is that we don't have a good grasp of comprehensive information. ?
4. Management information is the link inside and outside the organization.
The contact between enterprises and the outside world, as well as the contact between functional departments within enterprises, is also communicated with each other through information. Therefore, to communicate with various departments and make the whole enterprise run in harmony, we must rely on information. Therefore, it is the link between internal and external communication of the organization. Without information, it is impossible to communicate internal and external contacts and work together well.
Generate background:
In the 20th century, with the vigorous development of global economy, many economists put forward new management theories. In 1950s, Simon put forward the view that management depends on information and decision-making.
At the same time, Wiener published Cybernetics, and he believed that management was a process. Gail wrote in 1958: "Management will get timely and accurate information at lower cost and achieve better control." During this period, computers began to be used in accounting work, and the word data processing appeared.
In 1970, Walter T.Kennevan gave a definition to the emerging management information system: "report to the manager orally or in writing at an appropriate time."
Employees and outsiders provide past, present and forecast information about the enterprise and its environment to help them make decisions. In this definition, information is emphasized to support decision-making, but application model is not emphasized, and computer application is not mentioned. ?
1985 Gordon B.Davis, the founder of management information system and professor of management at the University of Minnesota, gave a relatively complete definition of management information system, that is, "management information system is a man-machine system that uses computer software and hardware resources to manually operate, analyze, plan, control and make decisions, and has a database.
It can provide information to support the operation, management and decision-making functions of enterprises or organizations. "This definition comprehensively explains the objectives, functions and composition of the management information system, and reflects the level of the management information system at that time.
