The thesis
Why this org is unusual
Howmet Aerospace’s most distinctive feature is that John C.
Plant simultaneously serves as Executive Chairman and CEO, concentrating authority at the top. The CEO has a notably small span of control, with only four direct executive reports shown in the current structure.

- CEO also serves as Executive Chairman
- No Chief Operating Officer role
- Lean C-suite for a Fortune 500 manufacturer
