What can this person deliver now?
Read the range, difficulty and independence already demonstrated in the work.
VITALIS™ S1 · The System
Three readings.One management loop.
VITALIS™ S1 (VS1) turns work managers already observe into a structured diagnosis of current capability, growth momentum and core vitality.
Built for ordinary work, VS1 combines direct observation, written anchors, dialogue and repeated sampling in one management process. It preserves the named work instances behind a reading, keeps the three questions separate and returns the result to the manager who observed the work and must decide what happens next.
VS1 is not a one-off assessment event or a single composite verdict. It is a structured way to examine current work, choose a proportionate response and return later to see what changed.
The system begins by separating three questions that are often collapsed into one impression.
Three questions · One architecture
One result can hidethree different realities.
VS1 reads current capability, growth momentum and core vitality separately because each can point to a different management action.
Axis 02 — Y · Growth momentum
At what rate is the work changing?
Read the direction and rate at which teaching, imposed change and personal feedback become improved work.
Axis 03 — Z · Core vitality
What appears to sustain the work when conditions become harder?
Read the care, effort and judgement visible when pressure rises, supervision reduces or the task becomes less convenient.
A capable person who is accelerating, a capable person who has stalled and an emerging person who converts feedback quickly should not receive the same response. VS1 therefore keeps X, Y and Z visible as separate readings rather than averaging them into one score.

X is tailored to the work
The structure stays fixed.The evidence must fit the role.
A hotel concierge, an IT support analyst and a logistics operator do not demonstrate reliable delivery in the same way.
VS1 therefore tailors the X-axis behavioural anchors to the industry, organisation and role. The tailoring process begins with role documents, SOPs, output definitions, critical incidents, recurring exceptions and evidence managers can genuinely observe.
The X-axis functions, construct boundaries and L1–L5 level logic remain fixed. The role language, behavioural examples, observable outputs and realistic role ceiling are tailored. Y and Z retain the same meaning and decision logic across industries; explanatory examples may be localised without changing the anchors.
- Understand the business and target role.
- Align L3 to the documented role standard.
- Translate the fixed capability functions into observable work anchors.
- Mark role ceilings, edge cases and evidence gaps.
- Calibrate disputed examples before live use.
Tailored to the work. Anchored to the same standard.
Once the questions and evidence anchors are clear, the reading can remain light enough to live inside ordinary management.
Built into the work
Built into work.Not added on top of it.
VS1 is designed as a lightweight, incremental management practice—not a separate assessment event.
The first reading is built over six to eight weeks from work that is already taking place. Managers capture only decision-relevant evidence as it occurs; entries can be saved in parts and completed across short sessions.
The current design target is approximately 20–30 minutes of total system input per person for a reading. It is not intended to require one uninterrupted sitting, a separate assessment day or additional work created for the purpose of being assessed.
Once sufficient evidence is available, the manager discusses relevant instances with the person, reads the three axes separately, chooses a proportionate next action and returns later to examine what changed.

Deeper analysis from the same evidence
Three readings.Four deeper analyses.
VS1 extends the three-axis reading through four deeper analyses that examine capability release, current drive, momentum and observed assignment conditions—without converting the evidence into a verdict.
PRG · Potential Release Gap
Is capability missing—or is observed capability not being fully released in the current work?
PRG is designed to surface a gap between capability already observed and the extent to which it appears to be released under current conditions. It helps a manager avoid treating every constrained result as a training problem.
Boundary“Potential” refers here to presently observed capability that may not be fully released. PRG does not calculate future potential or predict the performance uplift an intervention will cause.
DRIVE · Current investment intensity
Does the current pattern of effort, standards and response to change warrant closer review?
DRIVE combines selected growth-momentum and core-vitality evidence into a current review signal. It helps direct attention before a concern is reduced to a general impression.
BoundaryDRIVE is a designed review signal. It is not a prediction of resignation, retention or future performance.
GPI / DI · Growth Momentum Index / Decline Momentum Index
Is the present direction of change moving upward or downward?
GPI and DI summarise the direction of currently observed movement. GPI represents positive growth momentum; DI represents decline momentum. Together they help a manager see direction rather than relying on a static level alone.
BoundaryThese are momentum readings, not potential scores or forecasts of a future outcome.
8 Evidence Flags · Assignment safeguards
Which already-observed conditions require a safeguard, staged assignment or further evidence?
Eight evidence flags identify observed conditions that may matter before important work is entrusted. A flag should show what requires review, what work remains proportionate and what positive evidence could release the safeguard.
BoundaryThe flags do not predict a future incident. They organise evidence that has already been observed and keep the response proportionate to the work.

VS1 does not claim to invent direct observation, anchored judgement or repeated review; it brings those disciplines together for a specific management problem.
Precedent 01
Kazuo Inamori · The strategic distinction
The Result of Life or Work = Attitude × Effort × Ability
Kazuo Inamori's formulation supplied a strategic question: visible ability is not the whole explanation of a work result. VS1 carries forward that distinction by reading capability, growth momentum and core vitality separately.
It does not reproduce Inamori's numerical ranges, multiply the three axes or treat the formula as validation evidence for VS1.

Precedent 02
mini-CEX · Direct observation in real work
The American Board of Internal Medicine introduced the mini-Clinical Evaluation Exercise, or mini-CEX, in 1995. A supervising physician observes a trainee during real work, rates the encounter against written dimensions, provides feedback and repeats the process across situations.
In a 2003 study across 21 internal-medicine training programmes, 316 evaluators recorded 1,228 encounters involving 421 residents. Ratings showed statistically significant improvement across the first year of training. The instrument did not cause that improvement; it gave supervisors a structured way to observe it.
VS1 adapts five operating principles: real work, an accountable observer, written anchors, dialogue and repeated sampling.

Precedent 03
Structured interviews · The value of defined judgement
In personnel-selection research, revised meta-analytic estimates place the operational validity of structured interviews around .42, compared with .19 for unstructured interviews.
These figures concern hiring validity, not workplace observation. They do not transfer to VS1 and are not comparable with the mini-CEX reliability figure in the next section. They support one design principle only: when judgement matters, define the question, evidence rule and scoring anchor.

.19unstructured-interview operational validity
SOURCE FROM · Sackett, Zhang, Berry & Lievens (2022), “Revisiting Meta-Analytic Estimates of Validity in Personnel Selection,” Journal of Applied Psychology. The figures concern personnel selection and must not be presented as VS1 performance estimates.
Established disciplines can guide the design. VS1 must still establish its own evidence.
Structure does not remove disagreement. It creates the conditions for disagreement to be located and measured.
An evidence boundary
Structure is not certainty.It is inspectability.
Written anchors create the conditions for agreement to be tested—not assumed.
In a 2009 study, 52 internal-medicine faculty rated videotaped resident–patient encounters using both the traditional nine-point mini-CEX scale and a five-point scale. Inter-rater reliability for the overall rating was .43 on the nine-point scale and .40 on the five-point scale. The authors described reliability and accuracy as modest.
The .43 is useful because it shows that even a mature structured-observation method still faces rater variation. It is not a pass mark, a target or a VS1 result. Repeated evidence, explicit anchors, calibration and visible disagreement remain necessary.
There is no single error-free gold standard for workplace talent diagnosis. Any diagnostic judgement can be affected by incomplete evidence, observer variation and context. Calibration is therefore a required operating discipline—not an optional quality check. It tests how anchors are interpreted, makes disagreement visible and prevents confidence from standing in for evidence.
VS1 has no published inter-rater reliability result yet. Live deployments will examine rater agreement, evidence sufficiency, usability, the 20–30 minute input target and whether a second reading can support a practical management loop. The method, sample, limits and results should be reported—including if a result is lower than expected.

The standard is not certainty. It is a judgement whose evidence and disagreement can be examined.
The right next step is not a broader claim. It is a disciplined test in work where the evidence is visible.
