## GE Nine-Cell Matrix (GE–McKinsey Matrix)

The GE Matrix evaluates business units on two composite factors, making it more nuanced than the BCG matrix's single-metric axes.

### Two Dimensions

1. Industry Attractiveness — composite score based on: market size, growth rate, profitability, competition intensity, technological requirements

2. Business Unit Strength — composite score based on: market share, brand strength, production capacity, profit margins, technological capability

### Nine-Cell Grid (3 × 3)

### Three Strategic Zones

Green Zone (Invest/Grow): High attractiveness + Strong position → "Go ahead" for investment
Yellow Zone (Selectivity): Mixed conditions → selective, cautious investment
Red Zone (Harvest/Divest): Low attractiveness + Weak position → "Be careful"; minimise investment

### GE Matrix vs. BCG Matrix

Feature	BCG Matrix	GE Matrix
Cells	4 quadrants	9 cells
Axes	Single metrics (market share + growth rate)	Composite scores
Scope	Simpler; product/SBU focus	More comprehensive
Decision output	Stars / Cash Cows / Question Marks / Dogs	Invest / Hold / Harvest zones

Worked example

### Example 1

InnovaTech (RTP Jan 2025): InnovaTech uses the GE Matrix to evaluate two divisions:

AI Solutions Division — highly attractive industry + strong competitive edge → falls in the Invest/Grow (Green) zone → receives 'go ahead' for further investment.
Legacy Software Division — less attractive industry + weaker competitive position → falls in the Harvest/Divest (Red) zone → receives 'be careful' rating with limited investment recommended.

The GE Matrix allows InnovaTech to systematically prioritise resources toward high-potential units while reducing exposure to declining ones.

⚠️ Common exam mistakes

Confusing GE Matrix with BCG Matrix — GE has 9 cells vs BCG's 4 quadrants; GE axes are composite multi-factor scores while BCG uses single quantitative metrics
Thinking GE Matrix gives only binary invest/don't-invest decisions — there is a middle 'Selectivity' zone that requires case-by-case judgement
Overlooking that both axes in the GE Matrix are composite scores — a single factor like market growth rate alone does not determine industry attractiveness in this model
