■ Serious Issues with 'Legacy Open Systems' Lacking Personnel and Specifications
Currently, many companies are struggling with the 'black-box' nature of legacy open systems (such as VB6, VB.NET, older Java, and Delphi). Due to years of modifications and operations without updated documentation, coupled with employee departures, the 'overall picture' of these systems remains unknown to anyone.
As a result, companies face problems that affect business continuity, such as:
・Delays in troubleshooting when failures occur
・High risks due to an inability to analyze the impact of modifications
・Ambiguous man-hour estimates causing project stalls
・Inability to make informed decisions regarding future system migration
This makes it essential to correctly interpret source code and visualize current specifications (documentation).
■ The Reality Where Reverse Engineering Alone Is Not Enough
While reverse engineering is a crucial technology for understanding system structures and dependencies, many companies find themselves stuck in a situation where they can 'see' the structure but cannot 'utilize' the information because:
・The information obtained is fragmented and difficult to use as design documentation.
・The granularity is insufficient for modification decisions or impact analysis.
・Deep expertise in language-specific characteristics (e.g., VB6, Delphi) is required.
・It is unrealistic to document massive amounts of code manually.
In short, the barrier lies in organizing visualized information into 'usable design documentation.'
■ Automatically Generating 'Usable Design Documents' from Source Code to Accurately Visualize Structure
This webinar introduces a method to accurately visualize system structures and dependencies by automatically generating detailed design documents from source code using a proprietary reverse engine. Expected effects include:
・Easy identification of impact scope
・Easier understanding of module, screen, and data relationships
・Resolution of knowledge siloing and improved maintenance efficiency
・Clarification of materials for future migration/modification decisions
Currently, the company is offering a free trial service where they create sample design documents from the customer's source code. Details on how to apply for this will be provided during the seminar.
■ Future Functions: Summarizing Visualization Results with AI for Higher-Level Design
While this webinar focuses on current visualization capabilities, there are plans to implement AI-based summarization features. This will enable the automatic generation of higher-level documents, such as:
・Summaries at the basic design level
・Abstraction at the requirements definition level
*The AI summarization feature is currently under development; this webinar will only cover the implementation policy and roadmap.
