This document discusses Kenichi Ohmae's three key factors model for sustained competitive advantage. It describes how firms should segment customers based on objectives and market coverage to understand their needs. Companies must evaluate short and long term strategies like selectivity, outsourcing, and cost reduction. They can also differentiate their offerings through image, profit/cost structure differences, or balancing management talent, resources, and funding. The overall goal is to stay ahead of competition and maintain long term success.
