KPI Cards
One number, one question. Pick the card by what the reader is asking of it.
What is it made of?
Bar and legend share one order and a rank number so colour is never the only link between a segment and its row; shares under 3% merge into "Other".
Is it consistent?
"Is it consistent?" — an average hides the tail: a median headline next to p90/p95 read against a named SLA threshold, a box plot of the record-level distribution with the threshold drawn as a reference line, and the share past it stated in text.
Where will I land?
"Where will I land?" — a linear run-rate projection to the end of the quarter: solid actual, dashed projection, a ±1σ confidence range that widens toward period end, a labelled target line and a today marker separating the two, with the projection method stated in words.
What is the headline?
"What is the headline?" — one hero KPI (a big value, a named comparison vs target, a 13-week trend against last year) with three compact satellite KPIs beside it, each a value + signed delta vs target + a tiny trend, composed as one card with a single separation gesture.
What changed most?
"What changed most?" — the top 3 risers and top 3 fallers in a ranked depot field (on-time delivery, revenue), each row stating its rank, how many places it moved, and a diverging mini bar from a shared, stated zero axis. Distinct from stat-list-01's single-snapshot share bars: this is about movement between two points in time.
Compared to what?
"Compared to what?" — one wide card per KPI stacking three named baselines (target, last year, budget), each with a shared-scale dot strip so the same number's distance to every reference reads at a glance.
Will I make it by period end?
"Will I make it by period end?" — quarter-to-date Progress bars with a marker for the expected pace and a computed days-ahead/behind status, plus a Gauge card reading a rate KPI against its target and thresholds.
How big is it in human terms?
"How big is it in human terms?" — a rate restated as a small, countable fraction ("1 in 12 orders arrived late") via UnitChart, with the exact rate spelled out beneath the rounded headline and a comparison vs last year. Highlighted units use an accent fill against a neutral rest rather than hue alone.
Should I act?
"Should I act?" — a status (icon + text, never colour alone) read against a visible on-track/at-risk/off-track threshold scale with today's value marked, plus how long the current status has held.
How reliable is it?
"How reliable is it?" — a ratio/streak headline over a 30-day strip of day cells, missed days marked by shape as well as colour, with the current and longest streaks and a comparison to the prior 30 days.
Am I on target?
"Am I on target?" — a grid of KPI cards, each a BulletChart (value against target, last year, and 2–3 qualitative bands) plus a named comparison row and an as-of footnote. A lower-is-better KPI states that its bands read best-to-worst in reverse.
Better or worse than normal?
"Better or worse than normal?" — a 13-week Sparkline trend read against a target pace, last year, and a normal operating band, with a text legend spelling out the line styles so the encoding never rides on colour alone.
