ExaWizards Inc. group company Exa Frontier Edge jointly conducted a verification with 西部ガスHD by applying the Living Spec Generation Service to an accounting system built on a global ERP package. AI analyzed the source code and design documents and created specifications for automated journal-entry processing in approximately 2 weeks.
Using the Living Spec Generation Service provided by Exa Frontier Edge, a demonstration was conducted in September 2026 to create specifications for part of the automated journal-entry processing in an integrated accounting system built on a global ERP package. AI analyzed the source code and existing design documents.
The scope covered 21 programs and approximately 33,000 lines of code among the automated journal-entry processing programs in the accounting system written in PL/SQL. Specifications were created in approximately 2 weeks through AI-based static analysis. This enabled engineers to understand processing details and journal-entry results without reading through the source code line by line, confirming faster initial analysis and greater visibility into processing details.
The generated specifications also identified the relevant sections of the underlying source code, demonstrating that they can be used to streamline cross-checking against existing design documents. The companies will consider enhancing the specifications by incorporating a business perspective and expanding the scope covered.
西部ガスHD and Exa Frontier Edge stated that they will continue providing support to reduce the burden of initial analysis through AI analysis and improve the reliability of specifications, with a view to expanding the use of AI in core systems.
