The project adopted an agile methodology. The team prioritised more than 400 use cases on 800 web pages provisioned for the mobile web. The solution relied on responsive web design. This involves using a single application to serve 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 means that the client has protected its investment 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 customer using both existing systems and new end devices.
