What basic conditions should an enterprise develop a management information system have and what basic work should be done well? _Baidu...

1. Establish and improve the management system;Equip specialized talents to train members of the organization; select computer hosts and peripherals.

2. If you want to realize a management information system, you need to do the following work: demand analysis: clarify what functions the management information system needs to have and which business scenarios to design for. System design: Design the architecture, module, interface and process of the system based on the results of requirement analysis.

3. Basic data preparation. There are many basic data in the enterprise, such as product structure, process route, quota, standards, plan indicators, materials, equipment, personnel, suppliers, customer information, etc. in manufacturing enterprises.

4. Basic idea: Introduce the theories and methods of software engineering and system engineering into the research and development of computer systems, and adopt structured and modular top-down analysis and design of the system in accordance with the principle of user first.

How to develop a successful information management system

1. "botom-up" development strategy Starting from the business situation of the current system, we first realize specific functions one by one, and gradually establish MIS from low to high. Because the basic function of any MIS is data processing.

2. Basic idea: Introduce the theories and methods of software engineering and system engineering into the research and development of computer systems, and adopt structured and modular top-down analysis and design of the system in accordance with the principle of user first.

3. To make information management software, you can choose Microsoft's .net platform. .net is Microsoft's earliest open source platform. It is the easiest to learn and most used development platform. The language is naturally c# language. You can also choose java, but the learning threshold is high.

4. There are four main development conditions: superior leaders need to pay attention to the long development cycle of the management information system, which is expensive, and involves the change of management methods, so the main leader must personally grasp it to succeed.

5. Information system projects often cannot be implemented according to the scheduled schedule;The investment in information system projects often exceeds the budget; the visuality of the implementation process of the information system is poor; the project management of the information system, especially the supervision of information system projects, is often not paid attention to.

6. Therefore, it is necessary to ensure the uninterrupted operation of the machine, but it can only provide a short period of time and issue an alarm. Network design Hospital management system is a comprehensive system.

What are the stages of management information system development? What are the main tasks of each stage? For example_Baidu...

The main work of this stage is to carry out system development in batches according to the overall scheme of the proposed system and the arrangement of the development project determined in the system planning stage.This is the most heavy stage in system construction.

The software life cycle is divided into five stages: problem definition, feasibility study, requirements analysis, development stage and maintenance. The main tasks of each stage are as follows.

Specifically, it divides the entire information system development process into six independent stages, including system analysis, program design, system testing, operation and maintenance, and system evaluation. These six stages constitute the life cycle of the information system.

Responsible for organizing the conception, development, operation, maintenance and management of enterprise management information system. ( 4) Establish and maintain the data information standard specification and management system of the whole organization. ( 5) Track and study the new technologies and methods of information technology and apply them to the information management of the organization.

Briefly describe the differences between several development methods of management information systems

There are two categories, one is based on Windows system, and the other is based on Linux. There are also two major categories of development structure: one is based on C/s mode, which is equivalent to QQ or Notes, and the software needs to be installed on the client.

There are two main strategies for developing management information systems: "botom-up" and "top-down".

Object-oriented development method (1) Advantage analysis, consistency of objects in design and objects in software; realize software reuse and simplify programming: the system is easy to maintain; shortens the development cycle.

knotConstructive method Structured method is an information system development method composed of structured system analysis and design. The structured method is one of the most mature and widely used information system development methods at present.

Management information system development methods include: life cycle method, structured method, prototype method, face object method, etc.

. Information system planning stage The planning stage of the information system is also the conceptual stage of the information system or the demand analysis stage of the information system.
