Description: Engineering companies are increasingly acknowledging and acting upon the need to nurture innovation and creativity amongst their staff. Recognition and acceptance of TRIZ into mainstream engineering practice is growing fast, and it is estimated that in 5 years time it will have overtaken Six Sigma as a popular toolkit for innovative problem-solving. There is a need for a straightforward, simple and practical guide to understanding and implementing TRIZ, and with TRIZ for Engineers Karen Gadd draws upon her many years experience in teaching TRIZ effectively to achieve this. The book is illustrated throughout with cartoons commissioned by Gadd that illustrate the various concepts and techniques discussed and bring the theory to life. Innovative book that satisfies the need for concise, clearly presented information together with practical advice on TRIZ Employs explanatory techniques, processes and examples that have been used to train thousands of engineers to use TRIZ successfully Contains real, relevant and recent case studies from major blue chip companies Illustrates the principles and techniques involved with a series of colour cartoons that provide a visual reference that brings the theory to life.
