The document discusses BillerudKorsnäs' decision to transition its corporate website to a responsive design in 3 months. It notes that over 50% of its visitors were coming from tablets and smartphones, but its existing website was not optimized for mobile. A responsive design would allow the content to automatically adjust for different screen sizes and devices. This would provide all website content to all visitors, improve customer experience, and help boost the brand across different platforms and devices. The transition was completed within the targeted 3 month timeframe.
