Ge Matrix Calculator

Industry Attractiveness

Business Unit Strength

What is a GE Matrix Calculator?

The GE Matrix calculator is a strategic planning tool used by businesses to assess and manage their portfolio of products or strategic business units (SBUs). Developed by McKinsey & Company for General Electric in the 1970s, this framework, also known as the GE-McKinsey nine-box matrix, helps organizations decide where to allocate their resources. It evaluates business units based on two key dimensions: Industry Attractiveness and Business Unit Strength.

Unlike simpler four-box matrices like the BCG matrix, the GE matrix allows for a more nuanced analysis by using a 3×3 grid, representing high, medium, and low levels for each dimension. By plotting an SBU on the matrix, a company can determine the appropriate strategic approach: invest and grow, be selective and manage for earnings, or harvest and divest. This makes the ge matrix calculator an essential instrument for any manager looking to optimize their portfolio and drive long-term growth.

GE Matrix Formula and Explanation

The calculation behind the GE Matrix is not a single formula but a weighted scoring method. Each of the two dimensions, Industry Attractiveness and Business Unit Strength, is a composite of multiple factors. To get the final score for each dimension, you must:

1. List the Factors: Identify the key factors for both Industry Attractiveness and Business Unit Strength.
2. Assign Weights: Assign a weight to each factor based on its relative importance. The sum of all weights for one dimension must equal 100%.
3. Rate each Factor: Rate your business unit on each factor, typically on a scale of 1 to 5 (e.g., 1 = very weak, 5 = very strong).
4. Calculate Weighted Score: For each factor, multiply its weight by its rating to get the weighted score.
5. Sum the Scores: Add up the weighted scores for all factors within a dimension to get the total score for that dimension.

The formula for a single factor is: Weighted Score = Factor Weight (%) * Factor Rating (1-5). The total score for an axis is the sum of all its weighted scores. Our ge matrix calculator automates this entire process for you.

Example Variables for GE Matrix Analysis

Variable	Meaning	Unit / Scale	Typical Range
Market Size	The total potential revenue of the market.	Currency ($M) or Volume	Varies greatly by industry
Market Growth Rate	The annual percentage increase in market size.	Percentage (%)	-5% to +20%
Competitive Intensity	The level of competition in the market.	Rating (1-5)	1 (Low) to 5 (High)
Market Share	The SBU’s sales as a percentage of total market sales.	Percentage (%)	0% to 100%
Brand Equity	The perceived value and strength of the SBU’s brand.	Rating (1-5)	1 (Weak) to 5 (Strong)

Practical Examples

Example 1: Electric Vehicle (EV) Division of a Legacy Automaker

A traditional car company is evaluating its new EV division.

• Inputs (Industry Attractiveness): Market Growth Rate is high (Weight: 30%, Rating: 5), but Competitive Intensity is also high (Weight: 25%, Rating: 2) and regulatory hurdles exist. Overall Attractiveness Score: 3.8 (High).
• Inputs (Business Unit Strength): The company has strong Brand Equity (Weight: 30%, Rating: 4) but its relative Market Share is low (Weight: 25%, Rating: 2) and it lacks specialized tech. Overall Strength Score: 3.2 (Medium).
• Result: With High Attractiveness and Medium Strength, the strategic recommendation is Invest/Grow. The company should aggressively invest in R&D and marketing to improve its business strength in this attractive market. For more strategic analysis, consider our SWOT Analysis guide.

Example 2: Print Media Division of a Media Conglomerate

A large media company assesses its legacy newspaper division.

• Inputs (Industry Attractiveness): Market Size is shrinking (Weight: 30%, Rating: 1), and Profitability is low (Weight: 30%, Rating: 2). Overall Attractiveness Score: 1.9 (Low).
• Inputs (Business Unit Strength): The newspaper has a strong, loyal customer base (Customer Loyalty – Weight: 30%, Rating: 4) and high Brand Equity (Weight: 25%, Rating: 4). Overall Strength Score: 3.9 (High).
• Result: With Low Attractiveness and High Strength, the strategic recommendation is Selectivity/Earnings. The company should not invest heavily but manage the division for maximum cash flow while it remains profitable, a classic “cash cow” scenario. Explore this further with a BCG Matrix analysis.

How to Use This GE Matrix Calculator

Using our interactive ge matrix calculator is a straightforward process designed to give you actionable strategic insights quickly.

1. Review Factors: The calculator is pre-populated with common factors for both Industry Attractiveness and Business Unit Strength. You can use these as a starting point for your analysis.
2. Assign Weights: For each of the two dimensions, adjust the ‘Weight (%)’ for each factor. The weight reflects how important that factor is to you. The total weight for each column must add up to 100%. The calculator will show an error if it doesn’t.
3. Assign Ratings: For each factor, provide a ‘Rating (1-5)’ based on your assessment. A rating of 1 indicates a very unfavorable condition or weak position, while a 5 indicates a very favorable condition or strong position.
4. Calculate and Analyze: Click the ‘Calculate’ button. The calculator will automatically compute the weighted scores, display them, and plot the result on the 9-box matrix.
5. Interpret the Result: The position of your business unit on the matrix corresponds to a specific strategic recommendation:
   • Invest/Grow (Green Zone): Your SBU is in a strong position in an attractive industry. This is a priority for investment.
   • Selectivity/Earnings (Yellow Zone): The strategy is more nuanced. You might invest selectively, protect your position, or manage for earnings depending on the specific cell.
   • Harvest/Divest (Red Zone): Your SBU has low strength or is in an unattractive market. You should consider harvesting remaining value, or divesting the unit.

Key Factors That Affect a GE Matrix Analysis

The accuracy and utility of a ge matrix calculator depend heavily on the factors chosen and the objectivity of the ratings. Here are key factors that influence the outcome:

• Market Growth Rate: A fast-growing market offers more opportunities and is generally more attractive.
• Market Size: Larger markets can support more players and offer greater revenue potential.
• Competitive Intensity: Highly competitive markets can erode profitability and make it difficult to gain market share. This is a critical factor for Porter’s Five Forces analysis.
• Profitability: The average profit margin of the industry is a direct measure of its financial attractiveness.
• Relative Market Share: A higher market share compared to competitors is a strong indicator of competitive strength.
• Brand Equity: A strong brand is a significant competitive advantage that can command premium pricing and customer loyalty.
• Technological Capability: Access to proprietary technology or superior R&D can create a sustainable advantage.
• Management Strength: A skilled and experienced management team is crucial for executing strategy effectively.

Frequently Asked Questions (FAQ)

1. What is the main purpose of the GE Matrix?
The primary purpose of the GE Matrix is to help a company analyze its portfolio of business units or products to prioritize investments and allocate resources more effectively.

2. How is the GE Matrix different from the BCG Matrix?
The GE Matrix is more sophisticated than the BCG Matrix. While the BCG matrix uses only market share and market growth, the GE matrix uses multiple factors for its two dimensions (Industry Attractiveness and Business Unit Strength) and has a 9-box grid instead of a 4-box grid, allowing for more detailed recommendations.

3. Are the factor weights and ratings subjective?
Yes, the weights and ratings are subjective and rely on the strategic judgment of management. To improve objectivity, it’s best to involve a cross-functional team in the assessment and base ratings on solid data wherever possible.

4. What does the “Invest/Grow” strategy mean?
This strategy applies to business units in the top-left of the matrix (high attractiveness, high strength). It means the company should allocate maximum resources to these units to foster growth, gain market share, and solidify their leading position.

5. What is the “Harvest/Divest” strategy?
This applies to units in the bottom-right (low attractiveness, low strength). “Harvest” means reducing investment to a minimum to maximize short-term cash flow until the unit is no longer viable. “Divest” means selling or liquidating the business unit.

6. Can a business unit move on the matrix over time?
Absolutely. Market conditions change and a business unit’s strength can improve or decline. It is crucial to use the ge matrix calculator periodically (e.g., annually) to re-evaluate your portfolio and adjust your strategy.

7. How do I choose the right factors for my industry?
The default factors in our calculator are a good starting point. However, you should customize them to fit your specific industry. Think about the critical success factors in your market. For a tech company, “Innovation Rate” might be key. For a retail company, “Distribution Network” could be more important.

8. What if my total weights don’t add up to 100%?
For the calculation to be valid, the sum of weights for Industry Attractiveness factors must equal 100%, and the sum for Business Unit Strength factors must also equal 100%. Our calculator will alert you if the totals are incorrect.
