Snap's T-shaped leadership model combines a vertical stem of deep expertise with a horizontal bar of broad business understanding and human connection. Spiegel argues that modern work is too interconnected for expertise to remain isolated: leaders must apply what they know across product, engineering, design, legal, finance, and other functions. At the same time, breadth without depth can produce middle managers who know a little about many areas but cannot help solve a difficult problem or develop a specialist. The development sequence differs by starting point. A strong specialist can broaden through curiosity and engagement outside a comfort zone; a pure generalist must first build a substantive skill base. The desired output is trusted expertise that travels across organizational boundaries.

How to run it
- 1
Establish the stem
Identify and deepen an area of expertise that lets the leader contribute directly to difficult work.
Pro tip Test depth through the problems they can help others solve.
Watch out Status or management tenure is not the same as expertise.
- 2
Map the horizontal work
List the functions, stakeholders, and perspectives that the expertise must connect with to create impact.
- 3
Build cross-functional curiosity
Engage people outside the specialty, learn their constraints, and ask how they interpret the same problem.
Pro tip Start beyond the leader's normal comfort zone.
Watch out Breadth should not dilute the expertise that makes the leader useful.
- 4
Translate and connect
Express specialist knowledge in ways that other functions can use and combine it with their input.
In the wild
Spiegel describes working with co-founder Bobby Murphy on interactions such as tapping for a photo and holding for video. Design intent and engineering constraints had to be understood together for the product interaction to work.
→ Depth in different disciplines combined through a shared appreciation of the wider product.
Common mistakes
Promoting the empty generalist
Breadth without a deep contribution can leave a manager unable to solve problems or inspire specialist teams.
Keeping expertise in a silo
Technical depth creates limited organizational impact when the leader cannot connect it to other functions.
Is it for you?
Best for
It is best for selecting and developing leaders in complex organizations where specialist work crosses many functions.
Not ideal for
It is not a demand that every individual become expert in every discipline.
