The Crux Lexicon
The Crux Lexicon defines the core ideas that shape how we think about decision quality, delivery certainty, and performance under pressure. Use it as a shared vocabulary for conversations about Decision Flow, Integrated Intelligence, and the work of resolving the real constraint.
Core Decision Concepts
Decision Drag
Decision Drag is the friction between knowing and doing - the delays, misalignment, and rework that slow delivery, erode trust, and cloud judgment.
Decision Flow
Decision Flow is the discipline of seeing clearly, thinking together, and deciding well under pressure so decisions become clear, coordinated, and fast.
Integrated Intelligence
Integrated Intelligence aligns Human, System, and Machine Intelligence so that decision quality improves, learning accelerates, and coherence increases in high stakes environments.
Decision Tax
Decision Tax is the hidden cost of delayed or poor quality decisions - the accumulated impact of rework, risk, stalled progress, and inflated programme burn.
Decision Quality
Decision Quality describes how well a decision is framed, informed, owned, aligned, and executed, and how reliably it produces the intended outcome without creating new hidden risks.
Decision Latency
Decision Latency is the time between recognising that a decision is needed and making a clear, owned commitment that people can act on.
Predictability Index
Predictability Index is a measure of how reliably an organisation turns decisions into results, capturing delivery stability and the reduction of unwanted surprises.
Decision Integrity
Decision Integrity is the degree to which decisions are grounded in reality, clearly communicated, consistently applied, and followed through without drift.
The CRUX Method and Rhythm
CRUX Method
The CRUX Method is a four part discipline - Clarity, Reality, Uncover, eXecute - that gives leaders a repeatable rhythm for moving from uncertainty to action.
Clarity
Clarity is the practice of seeing the whole situation, cutting through noise, and defining the real decision that must be made now.
Reality
Reality is the discipline of replacing assumption with evidence, surfacing thinking traps, and grounding decisions in what is actually true.
Uncover
Uncover is the work of finding the hidden structural constraint that, once addressed, unlocks progress across multiple issues at once.
eXecute
eXecute is the commitment to decide, assign, move, and learn - turning intention into coordinated movement and measurable progress.
Systems, Labs, and Operating Model
Decision Lab
A Decision Lab is a focused intervention that brings the right people together to restore clarity, alignment, and momentum around a critical decision.
Decision Operating System
The Decision Operating System is the set of rhythms, routines, and rules of engagement that embed Decision Flow into how an organisation works every day.
High Stakes Delivery
High Stakes Delivery describes environments where delays, failures, or misalignment carry significant financial, safety, political, or reputational consequences.
Human and Collective Performance
Alignment Drift
Alignment Drift is the gradual spread in interpretations, priorities, and assumptions that causes teams who once agreed to start pulling in different directions.
Group Flow
Group Flow is the shared state in which a team is fully engaged, aligned on purpose, and able to solve complex problems with focus and ease.
These definitions are not theory for its own sake. They exist to help leaders see the real constraint, build a shared language for decision quality, and move faster with more confidence when the stakes are high.
