1, determine the basic problems of planning.
For example, planning years, planning methods, and determining centralized or decentralized planning.
2. Collect initial information.
Including collecting information from cadres at all levels, enterprises with similar manufacturers, various information system leading groups within enterprises, various documents, books and magazines.
3. Evaluation of existing status and identification of planning constraints. ?
Including objectives, system development methods, planned activities, existing hardware and its quality, information department personnel, operation and control, funds, safety measures, personnel experience, procedures and standards, medium and long-term priorities, external and internal relations, existing equipment, existing software and its quality, and ideological and moral status of enterprises.
4. Set goals.
Including the quality and scope of services, policies, organizations and personnel. It includes not only the goals of the information system, but also the goals of the whole enterprise.
5. Prepare the planning matrix.
List the matrix formed by the relationship between the contents of information system planning, and determine the priority order of the contents and their realization.
6. It is to identify the activities listed above and judge whether it is a one-time project activity or a repetitive and regular activity.
7. Determine the priority of the project and estimate the cost of the project.

Key technologies adopted in the implementation of information system;
1, computer hardware technology
Hardware infrastructure includes network platform, computer host and external devices. Computer hardware system is the operating platform of information system.
2. Computer software technology
Software is divided into system software and application software: system software refers to the software that manages, controls and maintains computers and peripheral devices and provides computers and user interfaces.
3. Computer network technology
Computer network is a system that connects computers, computer systems and other network devices distributed in different geographical locations with communication media, and realizes information exchange and network resource sharing with well-functioning network software.
5. Database technology
The database system includes data set, user's hardware, software and hierarchical model, network model database system and relational model database system. Relationship normalization theory is a powerful tool in the process of database design. Paradigm means that the relationship meets certain conditions.
Strategies for implementing and developing information systems;
1, unfeasible development method:
1) organization structure method: it refers to the mechanical division of the system according to the existing organization, regardless of the development principle of MIS.
2) Database method: refers to the developer developing the existing system from the database design.
3) Imaginary system method: refers to the developer's development based on the imagination of the existing system.
2. Feasible development methods:
1) Top__Down: it refers to the idea of structural design from the whole enterprise management, gradually from abstract to concrete, from overall design to detailed design.
2) Bottom__Up: It refers to the design of the components of the system. The whole system consists of building blocks, but the disadvantage is that the organic connection of the components of the system is ignored.
