The planning of information system is the first stage of system life cycle and the first step of system development process, and its quality directly affects the success or failure of this system development.
Information system planning is the main problem in information system practice and one of the main topics in management information system research. Modern enterprises are investing more and more in information systems. For example, Baosteel's investment is as high as 1 100 million yuan. The construction of information system is a huge investment and a lasting project. Poor planning not only causes its own losses, but also causes considerable indirect losses due to poor management of enterprises. Usually, people have an understanding that if an operation error may lose tens of thousands of yuan, then a design error may lose hundreds of thousands of yuan, a planning error may lose millions of yuan, and a planning error may lose tens of millions or even hundreds of millions of yuan. Therefore, it is necessary to overcome the one-sidedness of "emphasizing hard over soft" and put the planning of information system in an important strategic position.
The main contents of information system planning are divided into the following four aspects:
(1) What information systems do enterprises need?
(2) How to acquire these systems.
(3) Changes in the existing system and management environment.
(4) System emergency plan.
