Query: A book about successful collaboration

This is a book about a collaboration technique that is packaged as a book about leadership. Although good leaders collaborate, I felt cheated by what this book turned out to cover. Although the book presents sound principles and correctly advises readers to apply these principles personally before using them in groups, I felt that these principles were obvious, low-level stuff. I wanted something more advanced.
