Long a staple text of designers and design students around the world, Michael Johnson's Problem Solved is now available in an updated and expanded second edition from Phaidon. Conceived as a primer in design, branding and communication, the book is organized as a series of problems -- such as avoiding repetition, reinventing a tired brand, using shock tactics -- that are presented and solved, drawing upon real-world examples. The newly added nineteenth chapter considers the craze for flexible and ever-changing logos. Notes Johnson, "Everyone is exploring the idea that perhaps an identity no longer needs to be static, and could change and modulate with time."
