Reference #86: People Before Strategy
Top-level leaders should experience other functions (such as marketing, sales, HR), not just their primary field. This can be achieved through creating career paths that break out of the traditional promotional ladder within a silo.
For leaders already at a high level, this experience can be gained by spending time in various positions across business units.
