How can qualitative studies meet the challenges posed by new communications technologies and changes in consumer behaviour and attitudes? What is the impact of neuroscience research, the internet, social networks, emerging communities - of current and future scientific, technological and societal changes - on our methods? In an ever changing world, how to analyse and optimize a marketing or publicity project, a product or a brand strategy - how to create new concepts, new insights, and how to complete these tasks, internationally, under tighter deadlines and increasing budget constraints? This book aims to answer these questions by rethinking the foundations of the qualitative discipline, and by presenting recent developments in its methodology, practices and techniques. More than a mere manual, it offers a practical source of inspiration for qualitative studies and for marketing. Egalement disponible en français : Les études qualitatives
