Quality-led transformation enabling shift to automotive direct sales

success story

Quality-driven transformation enabling large-scale automotive direct sales

Our client, a leading German car manufacturer, launched the biggest IT program in its history from a blended indirect/direct sales setup to a direct sales-only model. To support this shift, the client required strong quality engineering capabilities across testing, test management, release management, and defect management for multiple products. We introduced a harmonized test automation and quality engineering approach that improved transparency, accelerated testing cycles, and enabled scalable operations across all markets.

Business overview

The transformation focuses on an online direct sales model for new vehicles and young used cars, covering both B2C and B2B scenarios. All core ordering processes including contracts, invoices, payments, and vehicle configuration run through existing applications that required extensive enhancements and new system development.

Background

As part of a large-scale retail transformation program, new customer journeys and operational processes significantly increased system complexity. This required coordinated quality assurance across numerous applications, teams, and markets to ensure consistent customer experience and operational stability.

Business need

The client sought an external partner to support testing and test management across multiple products, establish release and defect management processes for live markets, and scale automation while maintaining speed and reliability.

Our solution

We delivered a harmonized test automation and quality engineering solution across all dealer domain products – from planning and execution to automation and integration. Our approach was based on a modern, value-driven testing strategy focused on:

Customer-centric behavior
Risk-based prioritization of the most valuable behavior
Automation as first-class citizen, fully integrated into CI/CD pipelines
Fast feedback loops for early defect detection
Lean, transparent practices aligned with DevOps principles

Visibility was enhanced through Jira dashboards and standardized components enabled robust end-to-end testing across critical systems supporting dealer operations and customer transactions across Europe.
