There are many methods of management information system planning, including key success factors (CSF), strategic set transformation (SST) and business system planning (BSP).
Others include enterprise information analysis and integration technology (BIAIT), output/method analysis (E/MA), return on investment method (ROI), bookkeeping method, zero-line budget method, stepping stone method and so on. The first three are used the most.
1. critical success factor method
In the current system, there are always many variables that affect the realization of system goals, and several of them are key and main (that is, key success factors). Through the identification of key success factors, the key information set needed to achieve the goal is found out, so as to determine the priority of system development.
The key success factors come from the organization's goals, through the decomposition of the organization's goals, the identification of key success factors and performance indicators, until the data dictionary is generated. Identifying the key success factors is to identify the main data types related to organizational goals and their relationships. The key success factors of different organizations are different, and the key success factors of different periods are also different. When the key success factors are solved within a period of time, the identification of new key success factors begins again.
The key success factor method can grasp the main contradiction and make the target identification focus. Because managers are familiar with this method and use the goals set by this method, managers are willing to work hard to achieve these goals. This method is most conducive to determining the management objectives of enterprises.
2. Strategic goal set transformation method (SST)
The whole strategic goal is regarded as an "information collection", which consists of mission, goal and strategy. The planning process of management information system is the process of transforming the strategic objectives of the organization into the strategic objectives of management information system.
The transformation method of strategic goal set identifies management goals from another angle, reflects the needs of various people, and gives a structured method of layering according to this demand and then transforming it into information system goals. It can ensure that the goal is more comprehensive and less omitted, but it is not as good as the key success factor method in highlighting the key points.
3. Business System Planning Act
Information supports enterprise operation. By determining the system objectives, business processes and data from top to bottom, and then analyzing the data, the information system is designed from bottom to top. Management information system supports the realization of enterprise goals, expresses the requirements of all management levels, provides consistent information for enterprises, and has adaptability to changes in organizational structure.
Although the business system planning method also emphasizes the priority of goals, there is no obvious goal to guide the process. It leads to the system goal by identifying the "process" of the enterprise, and obtains the transformation from the enterprise goal to the system goal by analyzing the enterprise process/data class matrix.
