The GE McKinsey matrix is a 3x3 portfolio analysis framework that helps companies decide which business units to invest in, which to hold, and which to divest. McKinsey developed it for General Electric in the early 1970s as a more sophisticated alternative to the BCG matrix.

 

In this guide, you will learn exactly what the GE McKinsey matrix is, how to build one step by step with a worked scoring example, and how consultants use it in real client work and case interviews.

 

But first, a quick heads up:

 

McKinsey, BCG, Bain, and other top firms accept less than 1% of applicants every year. If you want to triple your chances of landing interviews and 8x your chances of passing them, watch my free 40-minute training.

 

What Is the GE McKinsey Matrix?

 

The GE McKinsey matrix (also called the GE matrix, McKinsey nine-box matrix, or GE McKinsey nine-cell matrix) is a strategic framework that evaluates a company's business units or product lines on two dimensions: industry attractiveness and competitive strength. The result is a 3x3 grid with nine cells, each suggesting a different investment strategy.

 

In the early 1970s, General Electric was managing roughly 150 business units and was unhappy with the returns from its portfolio investments. At the time, most companies relied on simple projections of future cash flows to allocate resources, which was unreliable. GE hired McKinsey & Company to build something better.

 

McKinsey took inspiration from the BCG matrix (a 2x2 grid using just market growth and market share) and expanded it into a 3x3 grid that incorporates multiple weighted factors for each axis. The result is a more nuanced and comprehensive view of where to invest, where to hold, and where to divest.

 

Having used portfolio analysis frameworks on real consulting projects at Bain, I can tell you that the GE McKinsey matrix remains one of the most commonly referenced tools in corporate strategy work. According to McKinsey's own publications, most large companies with a formal approach to modeling their businesses still refer to the nine-box matrix or some descendant of it.

 

What Are the Two Dimensions of the GE McKinsey Matrix?

 

The GE McKinsey matrix plots business units on two axes. The vertical axis (y-axis) measures industry attractiveness. The horizontal axis (x-axis) measures competitive strength, also called business unit strength. Both axes are divided into three segments: high, medium, and low.

 

What makes this framework different from simpler models is that each axis is a composite score built from multiple weighted factors, not just a single metric.

 

What Is Industry Attractiveness?

 

Industry attractiveness measures how profitable and appealing a particular market is for any company competing in it. This is entirely about external factors that no single company controls.

 

When evaluating industry attractiveness, look at long-term conditions rather than short-term trends. The investments required for a business unit typically demand a multi-year commitment, so a market that looks attractive today but is likely to decline in three years should score lower.

 

The most common factors used to assess industry attractiveness include:

 

• Market size and market growth rate

 

• Industry profitability and average profit margins

 

• Competitive intensity and number of competitors

 

• Barriers to entry and exit

 

• Supplier and buyer bargaining power

 

• Regulatory environment and legal risks

 

• Technology disruption potential

 

• Demand trends and seasonality

 

You can use Porter's Five Forces as a structured input tool to evaluate many of these factors. In my experience at Bain, the most common approach is to select six to eight factors, assign each a weight based on strategic importance, and then rate each factor on a scale of 1 to 5.

 

What Is Competitive Strength?

 

Competitive strength (or business unit strength) measures how well a specific business unit is positioned to compete in its industry. Unlike industry attractiveness, these are internal factors that the company can influence.

 

The key factors typically used to measure competitive strength include:

 

• Market share and market share growth

 

• Brand strength and customer loyalty

 

• Profit margins relative to competitors

 

• Product quality and differentiation

 

• Production capacity and operational efficiency

 

• Access to distribution channels

 

• Management quality and organizational capabilities

 

• Technological capability and innovation track record

 

Just like industry attractiveness, competitive strength is calculated as a weighted composite score. Each factor gets a weight and a rating, and the totals determine where the business unit falls on the horizontal axis.

 

What Are the Nine Cells of the GE McKinsey Matrix?

 

The 3x3 grid produces nine cells, which are grouped into three strategic zones. Each zone prescribes a general investment approach. The following table shows which strategy applies to each cell combination.

 

Industry Attractiveness	High Strength	Medium Strength	Low Strength
High	Invest/Grow	Invest/Grow	Selectivity/Hold
Medium	Invest/Grow	Selectivity/Hold	Harvest/Divest
Low	Selectivity/Hold	Harvest/Divest	Harvest/Divest

 

What Does Invest/Grow Mean?

 

Business units in the invest/grow zone sit in the upper-left corner of the matrix. They operate in attractive industries and have strong competitive positions. These are your best-performing assets.

 

The recommended strategy is to allocate significant resources to these units. That means increasing investment in R&D, marketing, talent, and capacity expansion. According to McKinsey's original framework documentation, these units should receive priority funding because they are expected to yield the highest returns.

 

What Does Selectivity/Hold Mean?

 

Business units along the diagonal of the matrix fall into the selectivity/hold zone. They have a mixed profile: either the industry is attractive but the unit is weak, or the unit is strong but the industry is unattractive.

 

The strategy here is cautious. Invest selectively only if you see a realistic path to moving the unit into the invest/grow zone. Otherwise, maintain the current position without committing major new resources. Monitor these units closely and be prepared to shift to a harvest or divest strategy if conditions worsen.

 

What Does Harvest/Divest Mean?

 

Business units in the lower-right corner of the matrix land in the harvest/divest zone. They operate in unattractive industries and have weak competitive positions. These are your weakest assets.

 

Two options are available. First, you can harvest the unit by reducing investment to a minimum and extracting whatever cash it still generates. Second, you can divest the unit entirely by selling it to a buyer who may be better positioned to compete. The proceeds from divestiture can be reinvested into units in the invest/grow zone.

 

How Do You Build a GE McKinsey Matrix Step by Step?

 

Building a GE McKinsey matrix involves five steps. The process is straightforward once you understand the mechanics, but the quality of the output depends entirely on how carefully you select, weight, and rate your factors.

 

Step 1: Identify Your Strategic Business Units

 

Start by listing every business unit, product line, or market segment you want to evaluate. Each one will be plotted as a separate point on the matrix.

 

For a large corporation, this might mean evaluating dozens of divisions. For a smaller company, you might evaluate three to five product lines or customer segments. The key is to define units at a level where meaningful strategic decisions can be made.

 

Step 2: Select and Weight the Scoring Factors

 

Choose six to ten factors for each axis. Then assign a weight to each factor based on its strategic importance. Weights should be decimals that sum to 1.0 for each axis.

 

For example, if market growth rate matters twice as much as seasonality in your industry, market growth rate should receive roughly twice the weight. Getting the weights right is the most subjective and most important part of the entire process.

 

Step 3: Rate Each Business Unit on Every Factor

 

Score each business unit on every factor using a consistent scale, typically 1 to 5 (where 1 is very unfavorable and 5 is very favorable). Use the same scale across all business units so the scores are directly comparable.

 

Involve multiple people in the scoring process whenever possible. Research from strategic management studies shows that group scoring reduces individual bias and produces more accurate placements on the matrix.

 

Step 4: Calculate Weighted Scores and Plot on the Matrix

 

Multiply each factor rating by its weight to get a weighted score. Then sum the weighted scores for each axis to get a total score for industry attractiveness and a total score for competitive strength. These two scores determine where the business unit lands on the 3x3 grid.

 

Here is a worked example for a hypothetical tech company evaluating two business units.

 

Industry Attractiveness Scoring Example

 

Factor	Weight	BU 1 Rating	BU 1 Weighted	BU 2 Rating	BU 2 Weighted
Market growth rate	0.30	5	1.50	2	0.60
Market size	0.25	4	1.00	4	1.00
Industry profitability	0.25	4	1.00	3	0.75
Competitive intensity	0.20	3	0.60	2	0.40
Total	1.00		4.10		2.75

 

In this example, Business Unit 1 scores 4.10 out of 5.00 on industry attractiveness (high), while Business Unit 2 scores 2.75 (medium). You would repeat this same process for competitive strength using factors like market share, brand equity, and production efficiency.

 

Once you have both scores for each business unit, plot them on the 3x3 grid. A unit with high industry attractiveness (4.10) and high competitive strength (say, 3.80) would land in the upper-left invest/grow zone.

 

Step 5: Determine Strategic Actions

 

Based on where each business unit falls on the matrix, assign one of three strategic directions: invest/grow, selectivity/hold, or harvest/divest. Then translate those directions into concrete actions.

 

For invest/grow units, that might mean increasing the R&D budget by 20%, hiring additional sales staff, or entering adjacent markets. For harvest/divest units, it could mean freezing all capital expenditure, cutting the marketing budget, or initiating a sale process.

 

One important nuance that many people miss: also consider where each unit is heading. A unit that currently sits in the selectivity zone but is projected to move into invest/grow territory within two years may deserve more investment today. Adding directional arrows to the matrix to show future projections makes the analysis much more useful for decision-makers.

 

GE McKinsey Matrix Example: How Would You Apply It to Apple?

 

To see the GE McKinsey matrix in action, consider how you might evaluate Apple's major business units. Apple reported $391 billion in total revenue for fiscal year 2024, split across several distinct product categories.

 

Here is how Apple's four main business units might plot on the matrix based on publicly available market data and analyst reports.

 

Business Unit	Industry Attractiveness	Competitive Strength	Strategic Zone
iPhone	Medium	High	Invest/Grow
Services	High	High	Invest/Grow
Wearables	High	Medium	Invest/Grow
Mac	Low	High	Selectivity/Hold

 

The iPhone generates roughly 52% of Apple's revenue and holds the dominant position in the premium smartphone segment. However, the global smartphone market is maturing, with single-digit growth rates according to IDC. That puts industry attractiveness at medium rather than high. Because Apple's competitive strength remains extremely high (strong brand, deep ecosystem lock-in, massive margins), the iPhone still falls in the invest/grow zone.

 

Apple Services (App Store, iCloud, Apple Music, Apple TV+) is the fastest-growing segment. The digital services market has high growth potential and strong margins. Combined with Apple's installed base of over 2 billion active devices (as Apple reported in early 2024), this unit scores high on both dimensions. It sits firmly in the top-left invest/grow corner.

 

Wearables (Apple Watch, AirPods) operate in a high-growth market, but Apple faces increasing competition from Samsung, Google, and others. Competitive strength is medium rather than high, which places this unit in the invest/grow zone but closer to the selectivity boundary.

 

The Mac sits in a mature PC market with low single-digit growth and thin industry margins. Apple's competitive strength is high thanks to its M-series chips and premium positioning, but the unattractive industry puts Mac in the selectivity/hold zone. This explains why Apple invests in Mac innovation (to maintain its position) but does not pursue aggressive market share expansion.

 

What Is the Difference Between the GE McKinsey Matrix and the BCG Matrix?

 

The BCG matrix and the GE McKinsey matrix are both portfolio analysis tools, but they differ in complexity, flexibility, and depth. The GE McKinsey matrix was specifically designed to address the BCG matrix's limitations.

 

Feature	BCG Matrix	GE McKinsey Matrix
Grid size	2x2 (4 cells)	3x3 (9 cells)
Axes	Market growth rate, relative market share	Industry attractiveness, competitive strength
Factors per axis	1 factor each	Multiple weighted factors
Complexity	Simple and quick to build	More complex, requires data and judgment
Categories	Stars, Cash Cows, Question Marks, Dogs	Invest/Grow, Selectivity/Hold, Harvest/Divest
Best for	Quick visual overview of portfolio	Rigorous, multi-criteria portfolio analysis
Limitation	Oversimplifies with single-factor axes	Subjectivity in factor weights and ratings

 

In practice, many consultants use both tools at different stages of a project. The BCG matrix works well for a quick initial view of a portfolio during a client workshop. The GE McKinsey matrix is better for the detailed analysis that follows, where investment decisions need to be justified with data.

 

What Are the Advantages and Disadvantages of the GE McKinsey Matrix?

 

Like any strategic framework, the GE McKinsey matrix has clear strengths and limitations. Understanding both will help you use it effectively and know when to supplement it with other tools.

 

Advantages	Disadvantages
Uses multiple factors for each axis, providing nuanced analysis	Subjective factor selection and weighting can introduce bias
Nine cells offer clearer strategic separation than four	Time-consuming and costly to conduct properly
Flexible criteria can be customized to any industry	Ignores synergies between business units
Helps prioritize limited resources for maximum returns	Requires experienced analysts or consultants for accuracy
Supports clear communication of strategic priorities	Static snapshot that needs regular updating

 

Based on my experience, the biggest practical limitation is the subjectivity of the weights and ratings. Two teams evaluating the same business unit can end up with different placements on the matrix. The best way to mitigate this is to involve cross-functional teams in the scoring process and test the sensitivity of your results by adjusting key weights by 10 to 20 percent.

 

How Is the GE McKinsey Matrix Used in Consulting and Case Interviews?

 

In real consulting engagements, the GE McKinsey matrix is one of the first tools pulled out for any portfolio strategy project. Private equity firms use it during due diligence to evaluate whether a target company's business units are worth acquiring. Conglomerates use it to decide which divisions to spin off during restructuring.

 

At Bain, I used variations of this framework on multiple client projects. The specific factors and weights change with every engagement, but the core logic of plotting business units on industry attractiveness versus competitive strength is always the same.

 

In case interviews, you will rarely be asked to build a full GE McKinsey matrix from scratch. However, the underlying thinking appears constantly. Any case that asks you to evaluate a portfolio, decide which businesses to invest in, or assess whether to enter a new market draws on the same principles.

 

For example, if you get a case about a conglomerate deciding which of its five divisions to invest in, you would want to evaluate each division on both the external market opportunity and the company's internal competitive position. That is the GE McKinsey matrix in action, even if you never draw the 3x3 grid. For a deeper look at how to use case interview frameworks effectively, check out our complete guide.

 

If you want to learn case interviews quickly, my case interview course walks you through proven strategies in as little as 7 days, saving you hundreds of hours of trial and error.

 

Here are three practical tips for referencing portfolio analysis concepts in a case interview:

 

• Always evaluate both the external environment (market attractiveness) and the internal position (competitive strength) before recommending investment decisions

 

• When comparing multiple business units, rank them using explicit criteria rather than gut instinct. Even a simple 1 to 5 rating system shows your interviewer that you think analytically

 

• Connect your portfolio analysis back to the case objective. If the client's goal is to maximize profit, recommend investing in units that score highest on both dimensions and divesting the weakest performers.

Frequently Asked Questions

 

Who Created the GE McKinsey Matrix?

 

McKinsey & Company created the GE McKinsey matrix in the early 1970s at the request of General Electric. GE needed a more sophisticated portfolio analysis tool than the BCG matrix to manage its portfolio of roughly 150 business units. The framework has since been adopted by companies and consulting firms worldwide.

 

When Should You Use the GE McKinsey Matrix Instead of the BCG Matrix?

 

Use the GE McKinsey matrix when you need a detailed, multi-criteria evaluation of your portfolio. Use the BCG matrix when you need a quick visual overview. The GE McKinsey matrix is better for formal strategic planning where investment decisions will be backed by data. The BCG matrix is better for initial screening or workshop discussions where speed matters more than precision.

 

Can Small Businesses Use the GE McKinsey Matrix?

 

Yes. Although McKinsey originally designed it for large conglomerates, any company with two or more product lines or market segments can benefit from the GE McKinsey matrix. Small businesses can use it to decide which products to invest in and which to phase out. The process is the same, just with fewer business units to evaluate.

 

What Factors Go Into Industry Attractiveness?

 

The most common factors include market size, market growth rate, industry profitability, competitive intensity, barriers to entry, regulatory environment, and technology disruption risk. You can customize the factor list based on what matters most in your specific industry. Each factor is assigned a weight and a rating, and the weighted scores are summed to produce a total attractiveness score.

 

How Many Cells Does the GE McKinsey Matrix Have?

 

The GE McKinsey matrix has nine cells arranged in a 3x3 grid. This is why it is often called the nine-box matrix. The nine cells are grouped into three strategic zones: invest/grow (three cells in the upper-left), selectivity/hold (three cells along the diagonal), and harvest/divest (three cells in the lower-right).
