Product Planning Essentials [PDF ebook] 

Concise yet comprehensive, Product Planning Essentials addresses the complex, interdisciplinary nature of product development and product management. It covers strategic issues that emerge during the product life cycle, including identifying opportunities, idea generation and evaluation, technical development, commercialization, and eventual product dismissal. Special topics include public policy, international issues, and intellectual property. An interesting summary of product development best practices from several companies appears at the end of the book. Instructors, students and practitioners will appreciate the balanced managerial and how-to orientation.
