Definition
A 2×2 for growth paths: Market Penetration, Market Development, Product Development, Diversification.

Introduction
Growth can come from more of the same customers, new customers, new products, or new businesses—each with different risk.

Explanation

Market Penetration: increase share with existing products/markets (pricing, promotions, loyalty).

Market Development: expand to new regions/segments/channels.

Product Development: new variants/features for current customers.

Diversification: new products + new markets (highest risk; related vs. unrelated).

Sequencing: move diagonally only after harvesting nearer plays.

Key Takeaways

Start with low-risk cells; prove unit economics; then expand.

Diversification demands capability fit or strong M&A logic.

Tie each move to clear KPIs and learning gates.
