My brother and I both sit on the leadership team, but our legacy sibling rivalry and childhood dynamics constantly bleed into our strategic planning sessions. How do we keep our family history from hijacking our business decisions?

Sibling dynamics on a leadership team can paralyze a company because childhood roles override professional accountability. When you and your brother sit on the leadership team, your team members spend their energy managing your personal relationship rather than solving business problems. To fix this, you must run your business strictly by the Accountability Chart, not your family tree.

First, look at the seats you both occupy. You must both clearly GWC (Get it, Want it, and Capacity to do) your respective seats. If your roles overlap or if there is ambiguity in who reports to whom, you must define the boundaries with extreme clarity.

Second, establish a strict rule that family discussions remain outside the office. During your Level 10 Meeting, you are peers or supervisor and direct report, not siblings. Use the IDS process to handle strategic disagreements. If a debate becomes personal, the Integrator must call a time-out and redirect the focus back to what is best for the business, as outlined in your V/TO.

Third, embrace vulnerability and build safety, as Daniel Coyle outlines in The Culture Code. Acknowledge to the rest of the leadership team that your sibling dynamic can sometimes create friction, and explicitly give them permission to call you out when family baggage starts to affect the room. When the team sees you accepting peer feedback without defensiveness, they will feel safe to hold both of you accountable.
