The document discusses Ian Huet's experience taking Vodafone.ie's website to a responsive web design. The goals were to convert high traffic pages to be responsive within a fixed timeframe using the Vodafone group framework. There were risks of affecting the existing site or not completing it on time given constraints. It describes responsive web design techniques like flexible grids using EM or %, flexible images with max-width 100%, and media queries. It also discusses challenges of designing without representative content, revisiting content patterns, and building performant pages through reducing assets, load speed, and leveraging client-side functionality. Planning is emphasized to identify unknown risks.
