The GE-McKinsey Matrix (a.k.a. GE Matrix, General Electric Matrix, Nine-box matrix) is just like the BCG Matrix a portfolio analysis tool used in corporate strategy to analyse strategic business units or product lines based on two variables: industry attractiveness and the competitive strength of a business unit. By combining these two variables into a matrix, a corporation can plot their business units accordingly and determine where to invest, where to hold their position, and where to harvest or divest. However, different from the BCG Matrix, the GE-McKinsey Matrix uses multiple factors that are combined to determine the measure of the two variables industry attractiveness and competitive strength. This is an important distinction, since the BCG Matrix has been criticized a lot on its use of only one single (and perhaps outdated) variable for each axis.
The name of the framework stems from the year 1970 in which General Electric (GE) hired the strategy consulting firm McKinsey&Company to consult GE in managing their large and complex portfolio of strategic business units. Therefore, it is McKinsey (not GE) that created the framework as a means to help GE cope with its strategic decisions on a corporate level.
