A small artifact for the coaching decision
A Driver Card is not another dashboard tile. It is a compact decision artifact for one athlete and one relationship: possible driver, outcome, effect estimate, interval, sample context, caveat, and decision license.
The card exists so the coach can see the useful part quickly without losing the uncertainty that keeps the recommendation honest.
What appears on the card
- The driver and outcome being evaluated.
- The evidence state and license: ADVISE, BORROW, WITHHOLD, or DECLINE/INSUFFICIENT.
- Effect estimate, interval, and sample context.
- Plain-English caveat and recommended wording boundary.
- Next data needed when the result is not yet coachable.
The four common states
ADVISEThe card can support a cautious training adjustment.
BORROWThe card uses a prior or comparable pattern, clearly marked as not athlete-owned proof.
WITHHOLDThe relationship is too fragile or uncertain to present as advice.
DECLINEThe available history is insufficient, so the card refuses the claim.
Why coaches use it
The card turns "more data" into a visible decision boundary: what to adjust, what to watch, and what not to say yet. It is useful for human coach review and for AI coaching agents that need evidence before language.
