First, the key success factor method (CSF)
1970 Professor William Zani of Harvard University used key success variables in the MIS model, which are the factors that determine the success or failure of MIS. 10 years later, Professor John Rockart of MIT improved CSF into MIS strategy. Using this method, we can identify the key factors of enterprise success, determine the information demand of the organization and understand the position of information system in the enterprise. The so-called key success factors are the important factors related to the survival and success of the organization. They are the decision-making information that organizations need most, and they are also the activity areas that managers pay attention to. In different organizations and different business activities, the key success factors are different, even in the same type of business activities of the same organization, at different times. Therefore, the key success factors of an organization should be judged by the organization, including the industry structure, competitive strategy, position in the industry, changes in the market and social environment, etc.
Second, the strategic goal set transformation method (SST)
The first step of this method is to determine the strategic set of an organization. First, check whether the organization has a written strategy or long-term plan. If not, it is necessary to build such a strategic set.
The second step is to transform the organizational strategy set into MIS strategy, which should include system objectives, system constraints and design principles. This transformation process includes determining the corresponding MIS strategic constraints for each element of the organizational strategy set, and then proposing the whole MIS structure. Finally, select a plan and send it to the general manager.
Third, Business System Planning (BSP)
Business System Plane Method (BSP) is a structured enterprise management information system planning method proposed by IBM in 1970s. It is similar to CSF method. First, the system objectives, business processes and data are determined from top to bottom, and then the system is designed from bottom to top to support the realization of the system objectives.
4. Comparison of three systems planning methods
The key success factor method can grasp the main problems and make the target recognition highlight the key points. Because senior leaders are familiar with this method, they are willing to work hard to achieve the goals set by this method. This method is most conducive to determining the management objectives of enterprises.
The transformation method of strategic objective set (SST) identifies management objectives from another angle, which reflects the requirements of various people, and gives a structured method of layering according to this requirement and then transforming it into information system objectives. It can ensure a more comprehensive goal and fewer omissions, but it is not as good as the former in highlighting key points.
