Team Scirocco Implements AI Development Support for Dojima Exchange's Market Information Display System

Team Scirocco LLC (Headquarters: Tama-ku, Kawasaki City, Kanagawa Prefecture; President and Representative Executive Officer: Arika Taniguchi; hereinafter "Team Scirocco") announced that its AI development support was adopted for the market information display system developed by Dojima Exchange, Inc. (Headquarters: Kita-ku, Osaka City, Osaka Prefecture; President and Representative Director: Hironori Shibano; hereinafter "Dojima Exchange") in conjunction with the relocation of its Osaka headquarters, and the operation of the system has commenced.

Due to its nature, this project required highly specialized knowledge regarding market information of financial products and the continuous operation of systems. Under the circumstances demanding rapid delivery and high standards for capturing user intentions, an AI-driven development process was adopted. This resulted in achieving 0% hand-written implementation code by humans, ensuring stable operation. By combining Team Scirocco's expertise in developing and operating financial business systems with the research and know-how in AI development for business systems at its wholly-owned subsidiary, Attena R&D Co., Ltd. (Headquarters: Tama-ku, Kawasaki City, Kanagawa Prefecture; President and Representative Director: Arika Taniguchi; hereinafter "Attena R&D"), the companies executed a challenging project that met user expectations at a high level. This approach achieved both rapid system construction and stability post-launch.

Background of Development

The origins of Dojima Exchange trace back to the Dojima Rice Market in the mid-Edo period. At the Dojima Rice Market, in addition to physical rice trading, systems and practices leading to modern futures trading were formed, laying the foundation for contemporary exchanges.

For Dojima Exchange, which has a history of pioneering new markets and systems, taking on the challenge of a new development process utilizing AI was not merely a technology introduction, but an extension of its proactive stance in embracing change.

On the other hand, this project was conceived after the schedule for the Osaka headquarters relocation was largely determined. It was necessary to develop a system to display market information and prepare it for operation within a limited timeframe before the relocation.

Therefore, Dojima Exchange sought a support company that possessed not only the development capability to handle rapid delivery but also the prerequisite knowledge regarding financial products, market information, and business operations.

Reason for Adoption

For systems involving financial products and market information, simply implementing screens and functions is insufficient. There are basic operational practices and user experiences (UX) naturally expected by users, including how information is presented, the approach to updates, ease of handling during operations, preparedness for failures, and ensuring a balance between development costs and functional benefits.

These areas are highly specialized, and explaining them from scratch to a development company imposes a significant burden. Especially in fast-tracked projects, it is difficult to achieve both speed and quality with support that only gathers requirements or a development process that uses AI merely as a task operator.

Team Scirocco was established in 2015 by a representative with experience as a securities trading system engineer. Focusing on the development and operation of financial business systems, system risk management, security, and cloud utilization, the company has supported the development and operation of financial product management systems for TSE Growth-listed companies and the DX Certification System for the Information-technology Promotion Agency, Japan (IPA).

Evaluating this understanding of financial operations and its lean, agile development structure, Dojima Exchange adopted Team Scirocco as the development support partner for this project.

AI-Driven Development Process

In this project, rather than treating AI simply as a code generation tool, an approach was adopted that integrated AI into the entire cycle of system overview design, feed information processing design, implementation, review, and improvement.

Humans focused on organizing business requirements, making design decisions, designing instructions for AI, reviewing deliverables, confirming quality, and selecting operational judgments. The creation of implementation code was carried out with AI as the core. As a result, 0% hand-written implementation code by humans was achieved.

This initiative leveraged Team Scirocco's expertise in developing financial business systems along with the research results of AI development for business systems from its wholly-owned subsidiary, Attena R&D.

If AI development is conducted without business knowledge, it merely accelerates output generation. However, by utilizing AI with an understanding of business constraints, operational site conditions, system safety, and the fundamental practices in the financial sector, it becomes possible to build a system that withstands actual operation while achieving rapid delivery.

Development Results

This project progressed under limited time constraints, expected to keep pace with the relocation plan that had little flexibility for schedule adjustments. By proceeding simultaneously with AI-based test implementations and human-led specification organization from the beginning, the system implementation advanced successfully.
