Our department heads work well in silos, but cross-departmental initiatives crawl at a snail's pace because leaders do not trust each other's execution timelines. How do we build genuine peer trust to accelerate operational speed?

Question

Tyler Smith · Accepted Answer

When department heads operate in comfortable silos, enterprise velocity drops to zero. As demonstrated in The Speed of Trust and The Five Dysfunctions of a Team, low trust creates operational friction, redundant communication, and endless second-guessing.

To eliminate cross-functional drag and build authentic peer accountability, implement these operational habits:
- Establish your leadership team as Team Number One. Your department heads must understand that their primary loyalty belongs to the executive table, not to their departmental fiefdoms. When their first priority is collective company performance, defending departmental borders becomes obsolete.
- Use your weekly Level 10 Meeting to force transparent collaboration. When a multi-department initiative stalls, do not let executives resolve it through back-channel emails or passive-aggressive hallway debates. Put the roadblock directly on the Issues List and use IDS to expose the root bottleneck.
- Establish measurable, single-threaded ownership on quarterly Rocks. Even when an initiative requires contributions from sales, marketing, and operations, exactly one leader must own the Rock on the Accountability Chart. That leader owns the outcome, while the supporting leaders are held accountable to specific milestone commitments.
- Increase vulnerability through structured quarterly check-ins. Leaders must be able to say out loud when they are behind on a deliverable without fear of political retaliation.

Cracks between leadership seats look like massive canyons to frontline employees. When your executives demonstrate mutual reliability, honor their commitments, and solve issues openly, team speed increases and departmental friction disappears.
