Vertical depth horizontal breadth = expertise innovation.

Key Principle: Be deep in your core competency, curious in everything.

T-Shaped Model:

• Vertical bar: Your deep specialty
• Horizontal bar: Breadth of curiosity

The intersection is where innovation happens.

Where it applies: Skill development, role specialization

Why it works: Specialization enables mastery; curiosity enables transfer

Risks: Too shallow = no value; too deep = brittleness; imbalance limits growth
