This document discusses the GE Nine Cell Matrix, which is a tool used in strategic portfolio analysis and planning. It involves plotting business units on a 3x3 grid based on their strengths and the attractiveness of the industry they operate in. Strengths and attractiveness are each rated as high, medium, or low. The matrix then recommends different strategic approaches - grow, hold, or harvest - for business units in each of the nine cells. It provides a framework for allocating resources effectively based on where a business unit sits within the matrix. The document outlines typical factors considered when rating strengths and attractiveness, and provides an example analysis of Maruti Udyog, an Indian automaker.
