Every assessment measures something. Very few measure behavior.
An honest map of the instruments an executive coach can put in front of a client, including the one we built. Each tool below earns its place by measuring something real. The question is which layer you need for the engagement in front of you.
The map
| Instrument | What it measures | What to know |
|---|---|---|
| 360 feedback | How others experience the person | The gold standard for perception data. Slow, political, and worth it for senior engagements. |
| DISC / MBTI / 16P | Self-reported preference, sorted into a type | Cheap shared vocabulary. Reads what the person claims, so it moves with self-image. |
| Hogan and similar | Personality inventory against norms | Serious psychometrics, well validated, still self-report at the input layer. |
| StrengthsFinder | Self-identified talents | Good for engagement conversations. Not built for pressure behavior. |
| VEX | How the person answers under light pressure | Consent-gated, eight minutes, one-page brief before session one. A read, not a psychometric norm table. |
How coaches stack them
A stack that works: VEX before session one, because it is fast and lands while rapport is still forming. A type instrument early if the client's organization already speaks that language. The 360 at the midpoint, once the client can hear it. The read tells you where to aim the engagement; the 360 tells you what the room sees; the re-read at the end shows the distance traveled.
What to be suspicious of, from any vendor including us: an instrument that outputs a score on a person for someone else's use without that person's consent and ownership. That is filing, not assessment. Every VEX read is consented and owned by the person read; if a tool cannot say that sentence, ask why.
Straight answers
Does VEX replace the 360?
Is VEX psychometrically normed?
Can a client fake it?
What does it cost next to the others?
Add the layer the others skip. Three clients free forever, no card. Keep your 360 and your inventory; VEX reads what they cannot.
