Wired Magazine's recently issue talks about radical transparency as a new trend in the industry. However, I think this is more of a buzzword-rallying-piece rather than more well-known customer-driven innovation business concept. Industry congnoscenti, Patricia Seybold aptly describes some of the goals, issues and processes involved in her book last year Outside Innovation (see my book list). I stil have to find time to finish reading the last chapters of it but I think it does a great job presenting the topic in a more useful manner.
