Updated: 24 July 2026
Tandem, dual leadership, top-sharing, co-CEO or co-lead – which model of shared leadership fits your situation? A comparison with a selection aid and the most common mistake in choosing a model.
Why the model is half the battle
Most shared leaderships fail not on willingness but on the wrong model for their decision structure. A founder duo needs something different from a corporate dual leadership. Choosing the model by sympathy or availability rather than by structure builds in the first conflict.
The models compared
| Model | Typical level | Responsibility | Decision logic | Typical pitfall |
|---|---|---|---|---|
| Leadership tandem | Team to area | One shared role | Mostly joint, clear exceptions | Roles never cleanly split |
| Dual leadership | Top level | Two full roles | Separate areas, joint principles | Unclear final decision |
| Top-/job-sharing | Part-time leadership | One position, two shares | Split by days/areas | Handovers and availability |
| Co-CEO | Company top | Shared overall responsibility | Highly formalised needed | Power balance externally |
| Co-lead in team | Team | Joint team leadership | Situational, pragmatic | Team unsure who does what |
The models individually
Leadership tandem
Two people share one role. Meant for situations where continuity and shared responsibility count. It holds when responsibilities are clearly split, and fails when „everything is done together“. More in the tandem coaching.
Dual leadership
Two full roles at the top, often with separate portfolios. Holds when the final decision is arranged; fails on power imbalance and unresolved fundamentals. Details in the dual leadership article.
Top-/job-sharing in leadership
A leadership position shared part-time. Ideal for work-life balance and talent retention. Stands or falls on handovers and availability. More in the job-sharing article.
Co-CEO
Two people at the company top. The most demanding model, because the decision logic must be highly formalised and the environment watches the power balance closely.
Co-lead in a team
Two people jointly lead a team. The lowest-risk entry into shared leadership – good for gathering experience.
Decision aid
- Is it one role being shared, or two full roles side by side? → tandem vs. dual leadership.
- Is part-time a central motive? → top-/job-sharing.
- Are we talking about the very top? → dual leadership or co-CEO, highly formalised.
- Do you want to gather experience first? → co-lead in a team.
- How clear is your decision structure already? The less clear, the more you need the more formal model.
The most common mistake
The model is chosen by sympathy or availability – „the two get along well“ – rather than by decision structure. It runs fine for a while and tips exactly when the first real conflict decision arrives and no one knows who makes it.
Frequently asked questions
Which model is easiest to start with?
The co-lead in a team, because the risk is small and you can gather experience before using shared leadership at the top.
Can you switch models later?
Yes, but a switch means renegotiating roles and decision rules. Better to choose the right model from the start.
What’s the difference between tandem and dual leadership?
A tandem shares one role, a dual leadership fills two full roles at the top. Details in the dual leadership article.
