You do not need another method. You need someone to hold the contradiction while you decide. This page sets out how we work, and what that way of working rests on.
Experience is not a theory
What we know comes from the field first: nearly thirty years spent on both sides of the table, watching decisions get made, deferred, and sometimes undone. No model replaces that.
But experience alone has a flaw: it always tells itself the same way, and it does not invite contradiction. So we anchor what we observe to established work - not to borrow academic authority, but to check that what we believe we have understood holds up against something other than our own memory.
We apply no one’s method under licence. This work informs; it does not prescribe.
Two models, and they do different jobs
KAIRNEXA uses two. One describes what we look at in a decision. The other describes how the work unfolds. Confusing them is the surest way to turn an instrument of confrontation into a methodology - which is to say, to lose the very thing that makes it useful.
The Decision Field - what we look at
Four dimensions: facts, assumptions, trade-offs, ownership. It is a model of analysis. It applies to one decision, it is public, and you can use it on your own, without us.
It does not tell you what to decide. It reveals what is not yet clear in your decision - and it is almost always the second column. The Decision Stress Test adds a fifth dimension, the next move, which exists only in session.
The four movements - how we work
Clarify, challenge, decide, return. It is a model of intervention. It describes how a session and an engagement unfold, never the content of a decision.
Clarify. What exactly is being decided, by when, and what does not deciding cost? Most sessions open on a subject that is not the subject.
Challenge. We take seriously the option you dismissed first, and we argue it against you, using your own numbers. This is the uncomfortable part, and it is what you came for.
Decide. What is settled. What stays open, and until when. The information still missing. And who carries it.
Return. The next session opens on what became of the previous decision. Without that movement, sparring becomes an agreeable conversation.
A simple way not to confuse them: the Decision Field fits on one sheet and you can fill it in alone tonight. The four movements require someone sitting opposite.
What we draw on
Four bodies of research cut across what we observe in session. They do not found our practice: they corroborate it, and occasionally correct it.
Noise, before bias
Poor decisions are readily blamed on the decision-maker’s biases. In Noise, Daniel Kahneman, Olivier Sibony and Cass Sunstein show that unwanted variability in judgement - two equally competent people, the same information, different conclusions - often costs more than bias, and is far less visible. Sibony draws a consequence we share: a bias is not corrected by individual clear-sightedness, but by the architecture of the decision.
That is why we work on how a committee runs rather than on the personalities in it. And why the question is never to hold all the information - Herbert Simon settled that long ago - but to know which missing piece would change the outcome.
What silence costs
Amy Edmondson found that the best-performing teams reported more errors than the others: not because they made more, but because they could say so. Psychological safety is not a pleasant climate; it is the condition for a disagreement to reach the table.
Chris Argyris had described the opposite mechanism: defensive routines - collective, perfectly polite ways of avoiding a subject, that nobody decided on and everybody maintains. In a leadership team it takes a recognisable form: the real disagreements are voiced after the meeting, in the corridor.
Who decides what
Many blockages taken for clashes of personality are decision rights that were never assigned. Bain’s RAPID model - who recommends, who must agree, who performs, who gives input, who decides - has the merit of making the question explicit. Patrick Lencioni describes what follows when it is not: without disagreement properly aired there is no commitment, and without commitment no accountability is held.
We do not install RAPID. We use it to ask the question committees work around: on this particular decision, who decides - and who decided that it would be them?
What depends on no one in particular
Ronald Heifetz distinguishes technical problems, where expertise is enough, from adaptive challenges, which require people to change something in what they do - and whose solution therefore cannot be handed to them from outside. Michael Beer documented what stops strategies reaching the ground: almost never competence, almost always dysfunctions that everyone sees and no one names in front of the chief executive.
That is why we produce no written recommendation. An adaptive decision you did not make yourself will not hold.
Where AI sits
We use an internal analysis capability, Catalya, ahead of sessions. It produces counter-angles: the option dismissed too quickly, the bias the framing conceals, the scenario nobody dares state. It never produces a recommendation.
Four red lines, which do not depend on our goodwill:
One. No person’s name, no company name, no identifying data enters any AI system. Situations are reformulated abstractly, by us, before any use.
Two. No recording, no transcript, no session notes exist - so none of it can be processed by anything.
Three. No internal document you send us is ever placed in such a system.
Four. AI is never in the room. Beforehand, never during, never between you and us.
A machine produces a hundred angles in a minute. It will not know which one costs you your committee. Judgement stays human - the one place where we are not trying to save time.
Where to start
On your own, tonight, without speaking to anyone: open the Decision Field. On one dated, specific decision: the Decision Stress Test. To see the mechanics at work: the eleven situations. And if you would rather begin with a conversation, thirty minutes is enough.
