We have two highly competent project managers, and we want them to share the Head of Delivery seat as co-leads to keep them both happy. Why does the EOS® process insist on only one name per seat?

Question

Tyler Smith · Accepted Answer

When two people are accountable, nobody is accountable. Putting two names in one seat on your Accountability Chart is an operational disaster. It leads to finger-pointing, slow decision-making, and massive confusion for the rest of the team who do not know which leader to listen to. The Accountability Chart requires one name per seat for a reason: absolute clarity. You must have one person who ultimately owns the outcomes and metrics for that function. If you have two highly competent managers, you must define the structure first. Perhaps your delivery department is growing and needs to be split geographically or by product line. If that is the case, you create two separate delivery seats on the Accountability Chart, each with its own clear jurisdiction and five distinct roles. One person goes in the East Delivery seat, and the other goes in the West Delivery seat. Each has independent accountability. If the department cannot be split, then one person must be the leader of the seat, and the other must report to them in a different seat. You cannot compromise the structure of your business just to avoid having a difficult conversation or hurting someone's feelings. If you want to build a valuable asset that is prepared for a clean exit, you need a clear line of command where everyone knows exactly who owns each decision.
