The GE McKinsey Matrix, developed by the consulting firm McKinsey & Company for the General Electric Company in the 1970s, is an extension of the Boston Consulting Group Matrix. It classifies business units or products into nine cells instead of four, and considers more factors than just market size and position. The two dimensions of the matrix are industry attractiveness and competitive strength. Industry attractiveness measures how attractive the industry is for your business unit or product, based on factors such as market size, growth rate, profitability, competition, customer needs, technology, regulation, and environmental impact. You can assign a score from 1 (low) to 10 (high) to each factor and calculate the weighted average to get the overall industry attractiveness score. Competitive strength measures how strong your business unit or product is compared to your competitors, based on factors such as market share, brand image, quality, innovation, customer loyalty, cost structure, distribution, and capabilities. You can also assign a score from 1 (low) to 10 (high) to each factor and calculate the weighted average to get the overall competitive strength score. The GE McKinsey Matrix is a useful tool for evaluating market attractiveness and competitive strength in order to make better decisions about investments and resources.
