DeWu Quality Management System Overview

Quality assurance at DeWu is presented as a systematic engineering discipline based on software testing, following a progressive development model. By tailoring implementation strategies, designing scenario plans, and iterating on test results, the team has accumulated a methodology suited to DeWu’s technology.

The DeWu Quality Management System, built over three years, consists of four core components—mechanism, process, method, and tool—aiming to achieve standardization, online execution, automation, and intelligence.

Mechanism : The iteration quality review mechanism serves as the foundation, ensuring each iteration’s risk is controllable before release.

Process : Separate testing and collaboration workflows are defined to reflect development quality and calibrate it with testing quality, thereby stabilizing overall product quality.

Method : Implementation is driven by the “Quality Month” activities, focusing on metrics such as on‑time test submission, smoke‑pass rate, daily defect clearing, defect introduction, and defect escape.

Tools : A suite of quality‑engineering tools supports the system, including RDC for standardizing and partially automating processes, a quality dashboard for observability, and various platform‑specific tools.

The framework applies the iteration quality review to identify risks, perform root‑cause analysis, and define mitigation or avoidance measures before launch, followed by post‑iteration reviews that calibrate goals with online operational results.

Demand classification uses Sponsor tags to separate business and technical requests, with distinct flows for business/technical iterations and projects, as illustrated in the generic testing workflow.

Key testing methods and tools include:

Automated API testing via an API automation platform.

Traffic replay for pre‑release validation.

Precise testing for targeted coverage based on code changes.

Monitoring alerts for defect detection and rapid response.

Front‑end inspection to catch UI errors early.

Dcheck for loss‑prevention and real‑time reconciliation.

Tool cost optimization focuses on conversion cost, integration cost, and usage cost.

The system emphasizes five “keywords”: stability, efficiency, experience, growth, and innovation, guiding continuous improvement.

In summary, the mechanism defines the overall framework, the process details the steps, the method provides concrete techniques, and the tools enable execution, together forming a comprehensive R&D quality management ecosystem.
