This book is designed to go one step beyond the other books and training available today. Its focus is to cover four of the most critical elements in ensuring product success, and to convey practical strategies, insights, tips and techniques that I have learned from hands-on experience defining, launching and marketing over fifty products during the last twenty years of my career. This includes best practices learned from Apple, Symantec, Adobe and dozens of startup and mid-sized firms that my company, the 280Group, has helped with Product Management and Product Marketing consulting projects.
