When a critical quarterly Rock requires deep execution from two different department heads, who owns it and how do we prevent it from collapsing into cross-departmental finger-pointing?

Question

Tyler Smith · Accepted Answer

Shared ownership is the death of execution. The moment you assign a quarterly Rock to two people, nobody owns it. When a project slips in week eight, the head of Marketing will blame Sales for not providing feedback, and the head of Sales will blame Marketing for delivering poor assets. Both leaders will point across the table, and the Rock will fail.

Every single Rock must have exactly one name next to it on the Accountability Chart. That person is exclusively responsible for crossing the finish line on day ninety, regardless of how many other departments must contribute.

To make this work, identify which seat holds the primary business outcome. If the Rock is implementing a new CRM, the ultimate beneficiary might be the Sales seat, even though IT must configure the software and Operations must build the training modules. Sales owns the Rock.

During the quarterly planning session, when the Rock is set, the owner must immediately identify the cross-departmental requirements. They turn to the other leaders in the room and secure explicit commitments before the session ends. The supporting leaders take specific sub-tasks or milestones on their own departmental scorecards or issue lists. If a supporting department drops the ball during the quarter, the Rock owner does not wait until week twelve to raise their hand. They drop the bottleneck into the Issues List of the weekly Level 10 Meeting and use IDS to clear the path. Single ownership creates relentless urgency because excuses are off the table.
