Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current change impact analysis methods using traceability management and keyword search often misidentify or miss requirements and specifications that are affected by changes, leading to increased development costs and potential system quality deterioration due to time-consuming errors and omissions.
Innovation Solution
An apparatus and method that combines traceability management and keyword search functions to calculate an influence score, sorting design information by probability of influence, using a CPU to input trace conditions, extract keywords, and output results, thereby reducing misidentification and missing impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traceability management is used for change impact analysis, then the analysis can be performed systematically, but misidentification and missing of influenced requirements and specifications occur
Solution Approach 1:
The patent combines traceability management with keyword search functionality to create a hybrid approach. The traceability matrix provides systematic tracking while the keyword search component enhances accuracy by searching for relevant terms across design information, thereby reducing both misidentification and missing of influenced requirements and specifications.
Solution Approach 2:
The patent introduces an intermediary keyword search mechanism between the change impact analysis and the design information. This intermediary component extracts keywords from traceability results and uses them to search for related design information, acting as a bridge that improves both the systematic approach and the accuracy of the analysis.
2Productivity
If keyword search is used for change impact analysis, then the analysis can be performed quickly, but misidentification and missing of influenced requirements and specifications occur
Solution Approach 1:
The patent merges keyword search with traceability management to achieve both speed and accuracy. The keyword search provides quick retrieval of related information while the traceability matrix ensures systematic coverage, together reducing misidentification and missing while maintaining high productivity.
3Measurement precision
If detailed examination of change impact is performed, then the accuracy of analysis is improved, but development cost increases remarkably
Solution Approach 1:
The patent replaces manual detailed examination with an automated hybrid system combining traceability management and keyword search. This substitution maintains high accuracy by systematically tracking and searching for influenced requirements while eliminating the time-consuming manual review process, thereby reducing development costs.
4Quantity of substance
If comprehensive change impact analysis is performed, then the completeness of results is improved, but system quality deteriorates due to omissions
Solution Approach 1:
The patent combines comprehensive traceability tracking with targeted keyword search to achieve both completeness and reliability. The traceability matrix ensures all influenced requirements are captured while the keyword search refines the results to maintain high system quality by eliminating omissions and erroneous specifications.

AI summary
In order to realize a method for analyzing an impact of change with less misidentification and missing, an apparatus for analyzing an impact of change for investigating a change impact range caused by a change in requirements and specifications includes: a storage unit that stores design information and keywords; an input unit that inputs a trace condition including the design information representing an origin of a change impact analysis in design conditions stored in the storage unit and the keywords stored in the storage unit; a CPU that receives the trace condition including the design information representing the origin of the change impact analysis and the keywords from the input unit, and calculates an influence score representing a probability of the influence caused by the change in the requirements and the specifications for each of the design information; and a display unit that outputs a result calculated by the CPU.
