Strategic Influence From Chief of Staff to the C-Suite

With Lauren Tilstra, Global Chief Marketing and Communications Officer at The World Bank Group

Lauren Tilstra, Global Chief Marketing and Communications Officer at World Bank Group, joined World 50 Chiefs of Staff for a conversation on strategic influence. Lauren shared insights on navigating organizational dynamics, gaining buy-in from stakeholder groups, and driving global impact informed by her tenure as Chief of Staff to Verizon's Chairman and CEO.

Defining the Role:

  • Establish a "Boss Contract": Create a written agreement with your principal that defines specific deliverables, time splits, and clear boundaries to prevent the role from turning into an administrative catch-all.
  • Start With the End in Mind: Map out the Chief of Staff agenda directly against the principal's multi-year vision and long-term legacy goals.
  • Set Clear Boundaries With EAs: Establish explicit lane ownership between the Chief of Staff and Executive Assistants to eliminate friction and ensure mutual respect for each role's value.
"If you don't put a very clear line in the sand about what a chief of staff does and doesn't do, then you will end up doing a whole host of things that you never intended to, and it will get in the way of the outcome you're trying to drive together"

Navigating Organizational Dynamics:

  • "All Boats Rise" or "Ironclad Gate" Approach: Both operating styles are effective depending on organizational needs.
  • Harness the Power of Quiet Influence: Avoid voicing personal opinions in broad Executive Leadership Team meetings to maintain total neutrality, saving direct counsel for 1-on-1 conversations with your principal.
