Our VP of Sales and VP of Operations want to co-own our new product launch seat because both departments are heavily involved. Why does EOS forbid having two names in one seat on the Accountability Chart?

Question

Tyler Smith · Accepted Answer

When two people are accountable for the same seat, nobody is accountable. Co-ownership is simply an institutional compromise designed to avoid hard conversations about decision rights and authority.

In business operations, split accountability creates friction, slows down execution, and confuses frontline teams. If a critical milestone gets missed on the product launch, who owns the failure? The sales leader will blame operational bottlenecks, and the operations leader will blame unrealistic sales promises. A leadership seat must have exactly one neck to choke.

To resolve this cleanly, dissect the work using the five core roles of the seat. Determine whether the primary business risk of the initiative is operational delivery or commercial traction. If the primary risk is shipping functional software, the seat belongs under Operations, with Sales providing input. If the primary risk is go-to-market positioning and customer acquisition, the seat belongs under Sales.

Another approach is to recognize that a product launch is not an ongoing operational seat at all. It is a quarterly Rock or a cross-functional project. In that case, assign one person as the Rock owner who drives the initiative to completion within the Level 10 Meeting, while keeping functional operational seats strictly limited to one name per box on the Accountability Chart.
