Challenge

The Starting Point

The Problem

ewz needed a digital solution to digitize business processes and give both private and business customers the ability to handle their requests online on their own. Integration into the complex IT environment of the City of Zurich posed a particular challenge.

The Solution

Quatico developed a tailored customer portal consisting of three components: a B2C portal for private customers, a B2B portal for business customers with mandate management, and a back office for customer service. The solution was built as a service-oriented architecture with micro frontends and integrated into Adobe Experience Manager (AEM).

Implementation

The Implementation

The ewz customer portal was built with state-of-the-art technologies and a future-proof architecture:

Service-oriented architecture

Several micro frontends were integrated into an Adobe Experience Manager (AEM) portal. A headless approach enables flexible and scalable further development.

Seamless data integration

Connection of a wide range of data sources including SAP and solar plant production data. Integration with the City of Zurich's 'Mein Konto' for seamless authentication.

Agile development methodology

Implementation of executable requirements through continuous dialogue with domain experts. Automated test scenarios serve as functional safety nets.

Optimized deployment pipeline

Restructuring of the system architecture for daily releases. Automated tests for functionality, design, and interfaces. Manual testing reduced to the essentials.

Results

Measurable Successes

The launch of the ewz customer portal led to significant improvements in efficiency and customer satisfaction:

Since 2015

Partnership with ewz

4 applications

On one shared design system

13 building blocks

Shared form components in the design system

One design system for all ewz applications

Every application used to build its forms differently. Today 13 shared form components are available, in use across three applications with consistent form tracking. Replacing the legacy forms is still outstanding.

Accessibility fixed centrally instead of four times

Findings from an external audit were triaged and corrected in the design system, so they take effect across all four applications at once. Verification runs automatically.

Load failures traced across system boundaries

The interface to SAP failed under load and the cause was unclear. Two load cases were traced from logs and code, the causes named, affected cases fully recorded and remedial measures prioritised as tickets.
