Strategic Planning Tools: BCG Matrix and GE Matrix Explained

Updated 10 October 2026 · Fact-checked

The BCG matrix classifies a firm's businesses by market growth rate and relative market share into stars, cash cows, question marks and dogs. The GE matrix uses a nine-cell grid of industry attractiveness and business strength. The Ansoff matrix picks growth strategies by product and market. Classify each business, then recommend a strategy.

Understand Strategic Planning Tools: BCG Matrix and GE Matrix

A diversified company runs many businesses, called strategic business units (SBUs). It has limited cash and management time. Portfolio analysis helps it decide which SBUs to fund, hold, harvest or exit.

The BCG growth-share matrix has two axes. The vertical axis is market growth rate (high or low). The horizontal axis is relative market share (high or low), which is your share compared with your largest competitor. Each SBU falls into one of four boxes:

Star: high growth, high share. It earns well but also needs heavy cash to keep growing. Strategy: invest to hold or build share.
Cash cow: low growth, high share. It earns more cash than it needs. Strategy: hold or harvest, and use the cash to fund stars and question marks.
Question mark (problem child): high growth, low share. It needs much cash and its future is uncertain. Strategy: build selectively or divest.
Dog: low growth, low share. It earns little. Strategy: divest, liquidate or harvest.

The GE (General Electric–McKinsey) matrix is a nine-cell grid. One axis is industry (market) attractiveness: size, growth, profitability, competition. The other is business unit strength (competitive position): share, brand, cost position, technology. Each axis is rated high, medium or low. SBUs in the top-left zone get invest/grow; the diagonal middle zone gets selective investment or hold; the bottom-right zone gets harvest or divest. It uses many factors, so it is more flexible than BCG.

The Ansoff matrix is different. It does not rate existing SBUs. It shows growth options using products (existing or new) and markets (existing or new):

Market penetration: existing products, existing markets.
Market development: existing products, new markets.
Product development: new products, existing markets.
Diversification: new products, new markets (highest risk).

For example, a Pune biscuit maker selling more in Pune through discounts is penetration. Selling the same biscuits in Gujarat is market development. Launching a protein biscuit in Pune is product development. Launching packaged juice in Gujarat is diversification.

Key rules to remember

Relative market share: Relative market share = Your SBU's market share ÷ Market share of the largest competitor; A value above 1 means you are the market leader. A value below 1 means a rival is bigger. The common dividing line is 1, though some questions use 1.0 or a stated cut-off.
BCG classification: High growth + High share = Star; Low growth + High share = Cash cow; High growth + Low share = Question mark; Low growth + Low share = Dog; Use the cut-off for growth given in the question. If none is given, state your assumed cut-off.
GE matrix axes: Industry attractiveness (vertical) × Business strength (horizontal), each rated High / Medium / Low; Nine cells in three zones: invest/grow, selective/hold, harvest/divest.
Ansoff matrix: Penetration (existing product, existing market); Market development (existing, new market); Product development (new product, existing market); Diversification (new, new); Risk rises from penetration to diversification.

How to solve Strategic Planning Tools: BCG Matrix and GE Matrix questions

Use this order for any question on BCG, GE or Ansoff. It earns step marks because each stage is visible.

1Identify which tool the question asks for, or whether it asks you to compare tools.
2List the SBUs or products and note the data given: growth rate, own share, competitor share.
3For BCG, compute relative market share for each SBU and compare with the cut-off (usually 1). Compare growth with the stated cut-off.
4Place each SBU in a box (star, cash cow, question mark, dog). For GE, rate the two axes and place the SBU in a zone.
5State the strategy for each box: invest, hold/harvest, build or divest.
6Comment on the portfolio as a whole: cash flow balance, need for new stars, and what to fund from what.
7For Ansoff, match each situation to a quadrant and mention the risk level.
8Close with a short recommendation and one limitation of the tool.

Quickest way: Two-line classification

When to use it: Use this for 2-mark MCQs and for quick classification tables in long answers.

Check growth first: high growth means star or question mark; low growth means cash cow or dog.
Check share next: high share means star or cash cow; low share means question mark or dog.
Recall cash flow: cow gives cash, star and question mark use cash, dog is weak.
For Ansoff, ask two questions: is the product new, is the market new? Both new means diversification.

Common mistakes in Strategic Planning Tools: BCG Matrix and GE Matrix

Swapping the share axis with absolute market share
Students read 'market share' and use the SBU's own percentage.
Fix: BCG uses relative share: own share divided by the largest competitor's share. A 20% share against a 40% rival gives 0.5, which is low.
Calling a star a cash cow
Both have high share, so they look alike.
Fix: Check growth. A star is in a high-growth market and uses much cash. A cow is in a low-growth market and generates surplus cash.
Recommending divestment for every question mark
Students treat low share as failure.
Fix: A question mark can be built into a star if the firm can fund it. Say 'invest selectively or divest' and justify using the data.
Saying the GE matrix has four cells
BCG is learnt first and the two are mixed up.
Fix: GE has nine cells, with axes of industry attractiveness and business strength. BCG has four cells and uses only growth and share.
Placing market penetration under new markets in Ansoff
Students mix up the product and market axes.
Fix: Penetration is existing product, existing market. Market development is existing product, new market. Product development is new product, existing market.
Listing the boxes without a strategy
Students stop at classification.
Fix: Always add the action for each SBU and a comment on overall portfolio balance, because the question asks for choosing strategies.

Worked examples

Example 1

Shreeji Industries has four SBUs. Market growth rate and shares are: A: growth 18%, own share 30%, largest rival 15%. B: growth 4%, own share 40%, largest rival 20%. C: growth 15%, own share 5%, largest rival 25%. D: growth 3%, own share 6%, largest rival 30%. Using a growth cut-off of 10% and a relative share cut-off of 1, classify each SBU under the BCG matrix and suggest a strategy.

Show the solution

A: relative share = 30 ÷ 15 = 2.0, which is above 1 (high). Growth 18% is above 10% (high). A is a Star.
B: relative share = 40 ÷ 20 = 2.0 (high). Growth 4% is below 10% (low). B is a Cash cow.
C: relative share = 5 ÷ 25 = 0.2 (low). Growth 15% (high). C is a Question mark.
D: relative share = 6 ÷ 30 = 0.2 (low). Growth 3% (low). D is a Dog.
Strategies: invest in A to hold leadership; harvest B and use its cash; build C selectively or divest if funds are short; divest or harvest D.
Portfolio comment: B's surplus cash can fund A and C, so the portfolio is balanced.

Answer: A = Star (invest), B = Cash cow (hold/harvest and fund others), C = Question mark (build selectively or divest), D = Dog (divest or harvest).

Example 2

Classify each action under the Ansoff matrix for a Nagpur-based snack maker: (i) running discounts to sell more of its existing namkeen in Nagpur; (ii) selling the same namkeen in Hyderabad; (iii) launching a new millet-based snack in Nagpur; (iv) launching ready-to-eat meals in Hyderabad. Which carries the highest risk?

Show the solution

(i) Existing product, existing market: Market penetration.
(ii) Existing product, new market: Market development.
(iii) New product, existing market: Product development.
(iv) New product, new market: Diversification.
Risk is highest where the firm has least experience with both product and market, which is (iv).

Answer: (i) Market penetration, (ii) Market development, (iii) Product development, (iv) Diversification. Diversification (iv) carries the highest risk.

Exam tips

For BCG numerical questions, always show the relative share calculation. Marks are given for the working, not only the box name.
In a difference question (GE vs BCG), write points side by side: number of cells (9 vs 4), axes (attractiveness and strength vs growth and share), factors (many vs two), and flexibility.
In MCQs, read the growth and share values and apply the cut-off given. Do not rely on memory of which box sounds best.
Add one limitation in long answers, for example BCG ignores synergies between SBUs and uses only two factors.
Practise Ansoff with one-line real examples. Examiners often give a scenario and ask you to name the quadrant.

Strategic Planning Tools: BCG Matrix and GE Matrix: frequently asked questions

What are stars, cash cows, question marks and dogs in the BCG matrix?

They are the four boxes of the matrix. A star has high growth and high share. A cash cow has low growth and high share. A question mark has high growth and low share. A dog has low growth and low share.

What is the difference between the GE matrix and the BCG matrix?

BCG has four cells and uses market growth and relative share. GE has nine cells and uses industry attractiveness and business strength, each built from several factors. GE is more flexible, while BCG is simpler.

How is relative market share calculated?

Divide your SBU's market share by the market share of the largest competitor. A result above 1 means you lead the market. Below 1 means a rival is larger.

Is the Ansoff matrix a portfolio tool like BCG?

Not exactly. BCG and GE classify existing SBUs. Ansoff shows growth options based on whether the product and market are new or existing. Both help in choosing strategies.
