How Zhejiang Mobile Achieved Industry‑Leading DevOps Maturity with OSS 4.0

Background and Assessment Result

On December 23, 2020, the GOLF+ IT New Governance Leadership Forum announced the tenth batch of DevOps continuous‑delivery assessment results. Zhejiang Mobile’s OSS 4.0 Capability Center successfully passed the third‑level evaluation of the "Research‑Operations Integrated (DevOps) Capability Maturity Model" conducted by the China Academy of Information and Communications Technology.

This marks the first time the network management core system of China Mobile’s network domain has achieved the third‑level DevOps continuous‑delivery standard, indicating that Zhejiang Mobile’s delivery capability is now at a leading domestic level.

Deputy Chairman of the China Communications Standardization Association, Ms. Dai Xiaohui, and Dr. He Baohong, Director of the Cloud Computing and Big Data Research Institute of the China Academy of ICT, presented the award to Zhejiang Mobile.

Project Overview

The OSS 4.0 Capability Center’s Performance Center is positioned as an enterprise‑grade service and platform‑level capability. Following the construction principles of “data unification, capability descent, unified openness, and application integration,” the project decouples upper‑layer applications, supports rapid and flexible development, and builds core network business capabilities.

DevOps Integration Strategy

Facing intense competition and the need for agile operations and low‑cost maintenance, Zhejiang Mobile launched a "DevOps Practice Alliance" in August 2019, collaborating with five partners and more than ten systems. The alliance built a telecom‑specific DevOps research‑operations integration system that unifies technology foundations, breaks down partner silos, and internalizes core capabilities such as business scenarios, core algorithms, data, source code, and software technology.

The standardized DevOps management system now shortens the business delivery cycle to one week, reduces release time to three minutes, improves build efficiency by 96.7%, and raises unit‑test coverage to over 80%.

Assessment Timeline

First Gap Analysis – May 20, 2020 : Two‑day assessment identified gaps against the third‑level model and produced an improvement plan.

Iterative Improvements – May 20 to Sep 13, 2020 : Five rounds of iteration with daily stand‑ups and weekly planning.

First Simulation – Sep 14‑15, 2020 : Revealed significant deviations, prompting rapid adjustments.

Four‑Round Simulations – Nov 11‑29, 2020 : Progressed to meet targets.

Final Assessment – Dec 1, 2020 (remote) : Six months of continuous improvement culminated in a remote evaluation.

Assessment Completion – Dec 2, 2020 : Two‑day review concluded successfully.

Key Outcomes

After more than a year of DevOps practice, Zhejiang Mobile adopted a "self‑developed + third‑party" development model centered on a unified OSS 4.0 system and DevOps methodology. The project consolidated five core capabilities—requirement management, source versioning, pipeline construction, automated testing, and operation monitoring—forming a telecom‑specific DevOps research‑operations integration.

The Performance Center’s pipeline and cloud‑based approach enable rapid, stable, and reliable service delivery, enriching the OSS 4.0 architecture and promoting DevOps adoption across other Zhejiang Mobile projects.

The successful standard assessment has boosted confidence in future transformations, affirming that agile network operations will continue to advance under the combined influence of DevOps theory and practice.
