Swisscom‘s online customer selfcare centre has been helping private and business customers manage their accounts for more than a decade. In addition to the existing desktop version, the company wanted to update the web app to provide an improved user experience on mobile devices. The challenge was to ensure the user interface was optimised for all of the many different mobile devices on which it would be used.
An interdisciplinary development team consisting of front end developers, user experience designers and a project manager team prioritised more than 400 use cases on 800 web pages provisioned for the mobile web. Thanks to responsive design a single application serves the same content for all devices, with the difference in display characteristics across the various devices being dealt with using CSS – a much more cost effective approach than setting up a new infrastructure for mobile devices. The solution offers investment protection in existing infrastructure and backend integration for the foreseeable future. By successfully upgrading the app whilst maintaining backward compatibility, Swisscom was able to meet the requirements of customers using both existing systems and new end devices.
