This document discusses the concept of blue ocean strategy, which involves creating new market space rather than competing in existing or "red ocean" markets. It explains that blue oceans are defined by untapped market demand, while red oceans involve competition over existing demand. The document outlines principles for formulating a blue ocean strategy, including reconstructing market boundaries, focusing on the big picture rather than numbers, and getting the strategic sequence right. Tools for blue ocean strategy creation are presented, such as the strategy canvas for mapping the current industry state and a company's strategic moves, and the four actions framework for eliminating, reducing, raising, and creating strategic factors. Characteristics of effective blue ocean strategies and risks to avoid with red ocean thinking are also summarized
