Nomura Research Institute, Ltd. will begin offering an AI-based “Current Visualization and Impact Analysis Service”. This service will help companies resolve the issues they face in modernizing their legacy systems2 due to the “2025 Cliff1 ” problem . Specifically , NRI’s unique know-how and AI will be used to grasp the overall structure of the current system and investigate and analyze the impact of system changes. This will support efficient and effective modernization planning, aiming for sustainable system transformation for companies.
“Current visualization” is essential for successful modernization. This is the process of clarifying the overall picture of the existing system and specifically understanding its functions and data flows. However, in many companies, technical debt4 has accumulated in the current system , leaving complex and opaque parts, and system design documents are also affected by incomplete documents and a mixture of various file formats such as handwritten, Excel, and Word, making visualization more difficult. As a result, defects occur when designing new systems because important functions are missing or dependencies between systems cannot be understood. This increases the risk of increased response costs and schedule delays.
The key to “current visualization” is the “redocumentation” of the system. “Redocumentation” is the process of extracting necessary information from existing design documents, codes, manuals, etc. and reconstructing them into materials that can be used in new systems. NRI proposes “redocumentation” using AI to help understand the current state of the system. This allows you to quickly and accurately understand the data flow of the entire system and provide a foundation for modernization plans.
AIを活用することで、複雑な企業システムのデータフローを効率的に把握し、計画の質を向上させることができます。また、様々なファイル形式の既存ドキュメントをAIが整理・構造化。手作業で作成するよりも高品質なリドキュメントを作成することが可能です。

また、作成した資料をもとに、最新の効率的なプラットフォームへの移行をサポートします。これにより、企業は効果的な移行戦略を策定し、業務の最適化を図ることができます。NRIでは、すでに多くの企業にリドキュメントを活用した成果物を展開し、システムの現状把握とモダナイゼーション計画の迅速な推進を支援しています。
Impact analysis is the process of analyzing the impact of system changes and evaluating the areas of change and the degree of coupling between systems. NRI’s “impact analysis tool” visualizes the relationships between system assets and can instantly show the scope of impact of changes and the degree of coupling between systems. This enables companies to quickly identify the scope of impact, accurately estimate the amount of work required, and minimize the risk of defects and failures that accompany system changes.
NRIでは、現行システムの調査や障害分析、モダナイゼーションにかかる作業量を削減するため、社内のシステム開発で影響度分析ツールの活用を開始しました。
NRI is expanding its modernization support services, including “current visualization and impact analysis services,” “AI reconstruction” and “AI testing and migration” that utilize AI. We plan to provide services that realize development support and automatic screen testing using AI in the first half of fiscal year 2025. Through these services, we aim to help companies grow and strengthen their competitiveness.
