[Visualizing Black-Box Legacy Systems on the Web] Progress Tracking Feature for Reverse Analysis Launched

## Challenges in Legacy System Modernization

"No design documents," "Unknown current specifications," "Lack of visibility into analysis progress." In the field of legacy system modernization, the 'black-box' nature of COBOL and other legacy systems is a significant challenge.

Wonderful Fly Co., Ltd. has announced the launch of a new feature for its "Wonder Robo Reverse Service," which uses AI to analyze legacy systems and generate design documentation, allowing users to check system overviews and analysis progress on the web.

This service analyzes COBOL assets, visualizing the overall system structure, program interdependencies, analysis progress, and documentation generation status. This supports understanding the structure of black-boxed legacy systems and facilitates the sharing of analysis progress during modernization projects.

## Service Overview

Wonder Robo Reverse Service is a reverse engineering service that uses AI to analyze source code from legacy systems such as COBOL, PowerBuilder, VB6, and Java. It organizes system structures and program relationships before generating various design documents.

By analyzing source code, the service organizes system configurations, CALL relationships, screen/form compositions, and table information, outputting them as screen designs, form designs, table definitions, and processing specifications.

## Key Features

1. Web-based System Overview for COBOL Assets
Previously, understanding the structure or interdependencies of legacy systems could be time-consuming. This service visualizes analysis results to assist in grasping the structure and connections of existing systems.

2. Web-based Analysis Progress Tracking
Users can check the analysis and documentation generation status via a browser. This makes it easier to verify how far the analysis has progressed, identify unanalyzed programs, and confirm if documentation is complete, facilitating progress reporting.

3. AI-Powered Design Document Generation
Based on the analysis results, the service generates screen designs, form designs, table definitions, processing flows, and program specifications, all exportable in Excel format.

4. Supporting Understanding of Existing Systems
For long-running COBOL systems where design documents are missing or knowledge is siloed, this service analyzes and organizes existing assets to support current state assessments and impact analyses.

## Potential Use Cases

- Current state analysis before legacy system modernization (organizing structure and relationships).
- Visualization of black-box systems (understanding structures in environments without documentation).
- Analysis of existing assets in SI projects (analyzing existing assets and supporting investigations).
- Structural assessment of systems for governments, financial institutions, and the insurance industry (maintenance support and structural verification for long-running systems).

## Future Outlook

We will continue to enhance the service by advancing system dependency analysis, impact analysis, and expanding support for additional languages to support legacy system modernization.
