    Behavioural evidence, defined

    Stable definitions for the language used across GuruNow's moments, research and measurement.

    Current as of 30 September 2026

    Moment
    A moment is a specific, recurring, uncomfortable conversation, defined tightly enough that you can walk into it, fail it and be observed doing either. It is not the Five Moments of Need learning-support model; here, the unit is the conversation a person must be able to handle.

    Walk-into test
    The walk-into test separates a moment from a competency. A moment passes if you could walk into it: a room, another party who wants something, a point where you have to act, an outcome you would recognise and a way to fail. "Telling a high performer their work has slipped when you know they've been trying" passes; "demonstrates emotional intelligence" fails.

    Behavioural marker
    A behavioural marker is a specific, observable feature of what a person said in a conversation, written so that it can be checked against a timestamped transcript.
    Source: Measurement
    Evidence classes
    Evidence classes distinguish the kind of observation being made, so a practice attempt, a delayed attempt and a real conversation are not treated as equivalent evidence.
    Source: Evidence
    Capability and evidence axes
    The capability axis describes how consistently the behaviours are demonstrated; the evidence axis describes the conditions under which that demonstration was observed. They are reported separately, never collapsed into one score.
    Source: Measurement
    Evidence rung
    An evidence rung states how demanding the observation conditions were, progressing from briefed practice towards delayed, unbriefed and real-work evidence.

    Held-out assessment
    A held-out assessment is an unbriefed attempt using a new counterpart and behaviours that were not disclosed to the learner, used to test whether capability transfers beyond rehearsal.
    Source: Measurement
    Conditional credential
    A conditional credential states the conditions under which performance was evidenced, including delay, counterpart difficulty and the behaviours observed; it is not presented as an unconditional claim of mastery.

    Primary share finding
    The primary share finding is that the problem leaders name is often not the one that recurs. A moment can appear in many cases while being the named problem in only a small share of them.

    Head–mouth gap
    The head–mouth gap is the difference between understanding what should be said and producing it in the conversation itself. Knowledge can be present while the observable behaviour is absent.
    Source: Measurement
    Role-play simulation
    A role-play simulation is a digital practice environment in which a learner responds to a realistic counterpart and receives feedback on the resulting conversation.
    Human-in-the-loop training
    Human-in-the-loop training combines scalable digital practice with human judgement and support at the points where context, escalation or professional oversight requires it.
