How Dongguan Securities Achieved Top‑Tier DevOps Maturity: A Detailed Case Study

Project Overview

Dongguan Securities, a state‑owned securities firm founded in 1988, operates a mobile trading app called “Zhangzhengbao”. The platform provides market data, trading, and information services for Shanghai, Shenzhen, Beijing, and New Third Board markets, serving as a key online trading channel.

DevOps Assessment Result

Automation of code scanning, CI, build, functional testing, and deployment, cutting integration time and bug rates.

Cost reduction and efficiency gains through faster builds and higher quality releases.

Improved core operational capability with standardized DevOps processes and feedback mechanisms.

Establishment of an industry benchmark for DevOps maturity.

Key Metrics

Static test coverage ≥ 60 % for existing code, ≥ 80 % for new code, 100 % success rate.
