Top-Sharing: Two People Sharing One Leadership Position
Top-sharing combines shared leadership responsibility with a shared position. To avoid permanent duplication, time, handovers, availability and decision authority have to be designed with particular precision.
In brief: Top-sharing combines shared leadership responsibility with a shared position. To avoid permanent duplication, time, handovers, availability and decision authority have to be designed with particular precision.
How can two people share one leadership position without handovers and duplication becoming the bottleneck?

From the idea to practical application
Time model
Start with actual availability rather than contractual percentages. Where do working hours overlap, which decisions can wait and where must one leader be fully authorised to act? The time model determines how much handover architecture the role needs.
Lead domains
Clear lead domains reduce the need to process every issue twice. Allocate domains where continuity and expertise benefit, while preserving a small set of core decisions that justify joint time.
Handovers
A handover should transfer decision state, open risk and commitments — not retell the entire day. Test what the other leader needs to act without a follow-up call; everything else is a candidate for removal.
Representation
Representation needs real authority. If the leader on duty can only take messages but not decide, the role becomes a part-time bottleneck. Make the scope of mutual representation explicit to the team and stakeholders.
Joint core decisions
Protect joint time for issues where two perspectives justify the cost: strategy, key people or changes to the mandate. If ordinary operations continually migrate into this core, top-sharing loses much of its time advantage.
FAQ
Frequently asked questions
Answers to the most common questions about this topic.
Is top-sharing simply job-sharing with leadership responsibility?
It combines a shared position or working-time model with leadership accountability. That makes handovers, representation, joint core decisions and visibility particularly important.
How much overlap time does a top-sharing tandem need?
There is no universal percentage. Joint time should match the real interdependence of the role; routine status updates can often be handled asynchronously.
How can a part-time tandem remain responsive?
Through clear lead domains, documented handovers, mutual representation capability and explicit rules about what may wait and what requires immediate action.
