Modern After-Sales System: Updating Legacy Tool for Better User Experience

Overview

Acrontum modernized the after-sales system of a major German automotive manufacturer and successfully migrated it to a scalable, cloud-native platform on Amazon Web Services (AWS). The original system had become fragmented and difficult to maintain due to years of expansions. As part of the modernization, key AWS services such as Amazon EKS, AWS Lambda, and Amazon RDS were used to transform the legacy architecture into a modular, high-performance environment.

Acrontum’s new solution integrated all systems, improved the user interface, and provided better data access. This simplified processes in the service centers, offered improved insights into parts sales and customer interactions, and ensured compliance with GDPR.

Client need

The client needed a solution to modernize the outdated after-sales system and consolidate fragmented data sources. The goal was to increase the efficiency of the service centers, reduce manual effort in order processing, and gain better insights into user and sales data.

Highlight

Within a month, the acrontum team developed a prototype to test initial concepts. A fully functional solution for the core features was delivered in less than a year.

Solution built

The new solution integrates previously isolated systems using Amazon API Gateway, significantly improving process automation and data flows between components. A user-friendly interface, delivered via a web application hosted on Amazon S3 and distributed globally through Amazon CloudFront, makes day-to-day work in service centers easier and improves access to spare parts and customer interaction data. In addition, insights from user and sales data drive continuous improvement of the experience.

Services Used

Stakeholder Analysis, Requirements Elicitation, Solution Conceptualization, Strategic Planning, Prototyping and Testing, Web Application Development, Back-End Systems, API Development and Integration.

Outcome

Client Situation

The client had relied on a variety of independent software systems to manage their after-sales system, which had been added over the course of a decade. This approach led to fragmented information and numerous data and information silos. Service centers had to search for spare parts in different systems and place manual orders, reducing efficiency and complicating access to crucial user and sales data.

Approach

Acrontum worked closely with the client to define the project goals, taking into account the system’s complexity. The implementation required significant coordination, as numerous teams and departments from four organizations were involved, and information was managed by various administrative units with their own requirements. Additionally, the diverse needs of global end users – including dealers, government agencies, training institutions, and various support levels – had to be considered. After extensive workshops and user research, the acrontum team developed a prototype within 30 days to validate concepts with end users and stakeholders. Based on the insights gained, an MVP was developed that included the core functions and a unified view of vehicle information. Additional features were continuously introduced modularly over a period of five years.

Outcome

The redesign of the after-sales system resulted in a modern and efficient system that significantly simplified access to vehicle and spare parts data. The early deployment of the pilot version allowed the service centers to immediately benefit from the improved features. Continuous feedback enabled ongoing development and optimization of the system. The integration of robust security measures resulted in a high security score of 90% in the AWS Security Manager.
