Rakuten speeds issue resolution 2x with OpenAI Codex integration

AI Impact Summary

Rakuten has deployed OpenAI Codex to assist in diagnosing issues and generating code fixes, accelerating remediation work. This integration can reduce manual boilerplate and parallelize patch creation, but it requires strong review, automated testing, and governance to prevent regression or security gaps. Business impact: automated Codex-assisted fixes reduce mean time to repair, lowering downtime and speeding time-to-value for bug-fix cycles.
