Two of our senior project managers want to job-share our Director of Project Management seat, splitting the 40-hour work week evenly between them. Can a job-share arrangement work on an EOS Accountability Chart, and how do we maintain single-point accountability?

Question

The foundational rule of the EOS Accountability Chart is absolute: there can only be one name in one seat. When two people share accountability for a single box, nobody is truly accountable. When balls get dropped, measurables slip, or a critical deadline is missed, shared ownership inevitably turns into finger-pointing or mutual excuses.

A job-share can function at an operational task level, but it cannot function at the seat level. If you have two part-time leaders who each work twenty hours per week, you must divide the responsibilities into two distinct, standalone seats on the Accountability Chart.

For example, split the function into Director of Project Quality and Director of Resource Scheduling, or split them by client vertical. Each seat must have its own five distinct roles, its own Scorecard measurables, and its own individual Rocks. One person must own each seat completely.

Alternatively, if the seat must remain a single, unified leadership role, you must choose one person to occupy the seat on the Accountability Chart. That appointed leader holds sole accountability for the results, attends the Level 10 Meeting, and answers for the numbers. The second person reports to that seat holder as a senior individual contributor or project specialist. You can share tasks and schedules, but you can never split accountability.
