I'm calling Ken Iverson the Alan Mulally of CEOs in the 1980s and 1990s. "Plain Talk" by Ken Iverson is one of my favorite business books, despite its lack of self-congratulation and the absence of so-called transformational management concepts.

Instead, this is a book about how people were treated, the concept of decentralization, bonus structures, and using instincts to make business decisions.

Plain Talk will also undergo a revival period, as the Audible version was released this month. In this conversation, you'll find out why Mark and Bruce rate this a five-star book.
