Originally written in French. Translated by AI — the meaning has been preserved, not the prose.
Short definition
A shared artifact — project glossary, one-pager, PR/FAQ, metric hierarchy, decision log, escalation rules — whose function is to force an organization to write down something it believed was already shared.
Full definition
The term belongs to no established body of governance work; in the articles on this blog it groups together objects that ordinary usage files separately under documentation, product framing or steering.
What brings them together is neither their format nor their recipient, but their mode of action: each imposes a constraint that disagreement doesn't survive — a single definition per word, a single page for the target and the promise, a single voice addressed to the customer, a rank among the success criteria, a written reason for each rejected option, a deadline beyond which a subject escalates.
In the articles on this blog, the coherence tool doesn't produce agreement and doesn't replace it. It reveals where agreement stops, and reveals it earlier than execution would have. The consequence is a sorting criterion: an artifact that forces nothing doesn't belong to the category, whatever its title.
Usage in the field
The term comes into play in discussions about an organization's alignment, about committees' mandates, about preparing a launch, and about the border between governance and bureaucracy.
Synonyms and variants
"Shared object", "alignment tool", "framing artifact". In ordinary usage, these objects are designated one by one — "the glossary", "the one-pager" — with no family name.
Not to be confused with
- Documentation — the body of writing that conveys a state of affairs to readers; it records what is decided, where the coherence tool constrains you to decide.
- Coordination ritual — a meeting or recurring check-in that maintains coherence continuously; it is replayed every period, where the artifact outlives the sessions and the people.
- Soft decision — Soft decision — a formulation recorded as a decision that relegates nothing; any coherence tool filled in without constraint becomes one, with one more document.
- Alignment — Alignment — the state of an organization where disagreements are legible; the tool is what produces that state, it isn't proof of it.
Examples
"A coherence tool therefore doesn't exist to make everyone agree. It serves first to reveal more clearly where agreement stops." — the usage in the sense retained here.
"A glossary can become decorative. A one-pager can be filled with vague sentences. […] Escalation rules can exist without being used." — the empty version of each of the category's objects.
Ambiguities / debates
The term is in tension with the usage that counts equipment rather than effect: saying of an organization that it "has the tools" is common, and says nothing about what they force.
Unsettled: the border with the ritual. Some arrangements are mixed — a quarterly review that requires rewriting the hierarchy of criteria partakes of both, and it isn't clear whether the artifact or the session produces the effect.
