The document discusses various strategic planning tools and models including the BCG matrix and Ansoff product-market growth matrix. The BCG matrix classifies business units into four categories - stars, cash cows, dogs, and question marks - based on their market share and industry growth rate. The Ansoff matrix outlines four growth strategies: market penetration, market development, product development, and diversification based on existing or new products and markets. Strategic planning helps analyze a company's situation, set goals and strategies, and evaluate performance over time to adapt to changes in the environment.
