3 Horizons, 1 Système (3H1S)

Qu’est le 3H1S — Trois Horizons, Un Système ?

3H1S stands for Three Horizons, One System.

The expression is deliberate. It is not a variant of the Three Horizons model, but a clarification of how the model is meant to be understood and used.

The Three Horizons describe different temporal logics within an organization:

Horizon 1 concerns what currently sustains performance.
Horizon 2 concerns transition, adaptation, and emerging alternatives.
Horizon 3 concerns longer-term transformation and future relevance.

These horizons are often presented as separate domains of work. When treated this way, organizations tend to over-invest in one horizon—usually the first—while neglecting the others.

3H1S rejects that separation.

The “one system” means that all three horizons coexist and interact within the same organization, at the same time. They are not sequential phases, departments, or optional initiatives. They are simultaneous operating logics within a single system.

Decisions made in Horizon 1 shape what becomes possible in Horizon 2.
Experiments in Horizon 2 determine whether Horizon 3 intentions can ever materialize.
Images of the future in Horizon 3 influence what is defended, funded, or constrained in Horizon 1.

Seen this way, the organization does not move from Horizon 1 to Horizon 3. It matures by learning to coordinate across all three horizons without fragmenting itself.

Why the “One System” Matters

3H1S rejects that separation.

Seen this way, the organization does not move from Horizon 1 to Horizon 3. It matures by learning to coordinate across all three horizons without fragmenting itself.

The emphasis on one system is what allows 3H1S to function as a maturity model.

Immaturity is not defined by being “too operational” or “not innovative enough.” It is defined by collapse:

collapsing everything into short-term execution,
or isolating transformation as an abstract future exercise disconnected from present decisions.

Maturity, by contrast, is the capability to hold tension across horizons:

to protect today without sacrificing tomorrow,
to explore change without destabilizing the core,
and to prepare for futures without turning them into slogans.

In this sense, 3H1S describes a form of systemic maturity: not progression through stages, but the ability to operate complexity over time as one coherent whole.
