CHANGE IMPACT RESEARCH SUPPORT DEVICE AND CHANGE IMPACT RESEARCH SUPPORT METHOD
First Claim
1. A computer-readable, non-transitory medium storing a change impact research support program for supporting a configuration management change that is a change to configuration management information including a plurality of constituent elements, the change impact research support program causing a computer to execute a process, the process comprising:
- extracting, based on a combination of already-modified constituent elements that are constituent elements that are already modified in a present configuration management change that is a configuration management change that is presently performed whenever the constituent element of the configuration management information is modified, already-processed changes similar to the present configuration management change from an impact relationship information storage unit that stores therein a combination of constituent elements modified in an already-processed change for each already-processed change that is a configuration management change performed on the configuration management information in past times;
computing, for each constituent element that is not yet modified in the present configuration management change, an impact that is a cumulative total of already-processed changes in which the constituent element is modified among the already-processed changes extracted at the extracting; and
selecting a constituent element that is a modification candidate by using the computed impact.

Abstract
There is provided a change impact research support device. Whenever CI included in configuration management information is modified, CIs modified along with a combination of CIs modified in the present configuration management change are extracted. Then, the more the number of modifications performed along with the combination of the CIs is, the higher impact is set for the extracted CIs, and the CIs are indicated to a user as modification-candidate CIs in descending order of impacts.

4. A change impact research support device for supporting a configuration management change that is a change to configuration management information including a plurality of constituent elements, the change impact research support device comprising:
-
an impact relationship information storage unit that stores therein, for each already-processed change that is a configuration management change performed on the configuration management information in past times, a combination of constituent elements modified in the already-processed change; an extracting unit that extracts, based on a combination of already-modified constituent elements that are constituent elements that are already modified in a present configuration management change that is a configuration management change that is presently performed whenever the constituent element of the configuration management information is modified, already-processed changes similar to the present configuration management change from the impact relationship information storage unit; and a modification-candidate selecting unit that computes, for each constituent element that is not yet modified in the present configuration management change, an impact that is a cumulative total of already-processed changes in which the constituent element is modified among the already-processed changes extracted by the extracting unit, and selects a constituent element that is a modification candidate by using the computed impact. - View Dependent Claims (5, 6)

7. A change impact research support method performed by a change impact research support device for supporting a configuration management change that is a change to configuration management information including a plurality of constituent elements, the change impact research support method comprising:
-
extracting, based on a combination of already-modified constituent elements that are constituent elements that are already modified in a present configuration management change that is a configuration management change that is presently performed whenever the constituent element of the configuration management information is modified, already-processed changes similar to the present configuration management change from an impact relationship information storage unit that stores therein a combination of constituent elements modified in an already-processed change for each already-processed change that is a configuration management change performed on the configuration management information in past times; computing, for each constituent element that is not yet modified in the present configuration management change, an impact that is a cumulative total of already-processed changes in which the constituent element is modified among the already-processed changes extracted at the extracting; and selecting a constituent element that is a modification candidate by using the computed impact.
