Competitive Strategy is the landmark book on strategy by Harvard Business School Professor and author, Michael Porter. Mr. Porter condensed his classic to this 10 page text, narrated by Simply, and thought to be exceedingly effective in this format. Many observers believe the best business books are one hour of narration and 10 pages of text. This article meets both criteria and is a remarkably well put together series of thoughts by Mr. Porter. This audiobook repays replaying whenever confronted by a competitive situation in business. Testing your situation against Mr. Porter's thoughts is always a promising enterprise with productive results. Steve Jobs favorite Book.
