2. Description of the Related Art In the maintenance work of a system accompanying a specification change or the like, it is very important to analyze the degree of influence of modification of a certain program on another program and to accurately determine a program to be maintained. . If there is any omission in the impact analysis work, there is a possibility that the program required for changing the specification may be omitted. In fact, when analyzing system maintenance failures, failures due to undetected correction target programs required for specification change account for about half or more.

A veteran technician who has experienced system maintenance for a long time can easily combine the purpose of the specification change and the contents of the maintenance with the program name. With a probability close to, programs in the affected area can be recognized. However, since there are few such engineers and it takes a lot of time to develop such experienced engineers, young engineers are also required to identify such programs that are affected by the specification change. A technique that allows easy implementation is desired.

[0004] With respect to this type of technology, for example, a technology described in Japanese Patent Application Laid-Open No. 8-263701 is known. In this technology, various events (maintenance service information, failure response information, system introduction information) that occur from the system introduction to the start of system operation are stored in a database and centrally managed, so that technical support and failure response at the time of system switching can be performed quickly. To facilitate the system deployment work and the start of operation.

However, in this technique, the maintenance service information and the failure handling information can be quickly searched by making a database of the maintenance service information and the failure handling information, but the analysis of the range of influence by the program modification is taken into consideration. It has not been. Therefore, even with this technology, in the system maintenance work associated with the specification change, it is necessary to manually analyze the degree of influence of the modification of the program on other programs and grasp the program to be modified. Depends on your ability.

[0006]

The problem to be solved is that, in the prior art, if a veteran engineer is not a technical expert, it is easy to accurately specify a program that needs to be modified in accordance with a change in specifications. That is not possible. SUMMARY OF THE INVENTION An object of the present invention is to provide a specification change maintenance work support system capable of solving the problems of the related art and improving the efficiency of maintenance work accompanying a specification change, and a recording medium recording a processing program thereof. It is.
