Many executives develop deep expertise in a specific function or industry, which is valuable, but I would encourage aspiring directors to broaden their experience earlier in their careers. Being too narrowly focused can limit your marketability for board service, while boards benefit from directors who bring both depth and breadth of perspective. Exposure across industries, geographies, and business functions allows you to contribute more meaningfully when boards think strategically about their business and competitive landscape. ​ One way to build that perspective is by serving on nonprofit boards, which can provide early governance experience outside your core industry. Within your company, seek opportunities for role rotations or assignments in different divisions or geographies. The key is to continuously expand your knowledge and experience so you can bring a broader strategic lens into the boardroom.
