Basics Design 08: Design Thinking [PDF ebook] 

Basics Design 08: Design Thinking is an introduction to the process of generating creative ideas and concepts. It teaches the generation of ideas as a practical skill, vital to the creation of successful design. This focus on ideas and methods eschews an abstract, academic approach in favour of a useable methodology for design as a problem-solving activity. This is supported by practical work examples and case studies from leading contemporary design studios, accompanied by concise descriptions, technical expansions and diagrammatic visualizations.
