Vital Signs: Measuring the Seat, Not the Sitter

Most organizations measure either nothing or everything. Vital Signs are the middle path: a small number of figures a circle or a role has deliberately chosen to watch, kept current with almost no effort, and read as information rather than as a verdict.

The rule that shapes everything else

A vital sign belongs to a circle or a role, never to a person. It measures the seat, not the sitter.

This is not a nicety. A metric attached to a person becomes a performance file, and a performance file changes what people are willing to record. A metric attached to a role survives a handover, tells the next role holder what this seat is responsible for, and stays a fact about the work rather than a fact about a human being. When someone steps out of a role, the vital sign stays exactly where it was and keeps its history.

Without a Target it is a health metric. With one it is a key result.

There is one record type and one distinction:

• No Target means a standing health metric. Something you watch continuously because it tells you how a domain is doing. Review backlog, volunteer hours, response time. It has no finish line.
• A Target turns the same record into a key result. Something you are trying to reach by a point in time. This is the familiar OKR shape, without needing a second system.

Both live in the same place, and a metric can move between the two as intentions change. Add a Target when a health metric becomes a goal; remove it when it goes back to being something you simply watch.

What each vital sign carries

• Unit: what the number is counted in.
• Direction: Higher is better, Lower is better, or Stay in range.
• Baseline: where it started, so movement is legible.
• Current Value and Last Measured: the reading, and when it was taken.
• Cadence: Weekly, Monthly, or Quarterly. How often a reading is expected.
• How to Measure: the sentence that stops two people producing two different numbers.
• Source: Manual, Sera-observed, or Auto (system).

Write How to Measure before the first reading. It is the field that decides whether the metric survives contact with a second person. "Volunteer hours" measured as logged shifts and "volunteer hours" measured as hours anyone was present are different numbers wearing the same name.

Passive tracking: numbers you already say out loud

You do not have to open a form to keep a vital sign current. When someone states a measurement in a meeting or an email, Sera picks it up and proposes it as an update. "We had 42 volunteer hours last week" becomes a proposed reading on the volunteer hours vital sign, marked Sera-observed, waiting for confirmation.

The boundary is strict: Sera only ever captures a number that was explicitly stated. She does not infer a measurement, estimate one from context, or reconstruct one from partial information. A metric that was not said is left empty, because a fabricated reading is worse than a missing one.

Auto (system) signs are the third kind: values the hub can count for itself, such as a review backlog. Nobody has to report those at all.

Health is arithmetic, not opinion

Every night a deterministic task compares each vital sign's current value against its baseline, target, and direction, and writes one of four Health values: On Track, Attention, Off Track, or Not Yet Measured. It writes only the health field, and only when it changes.

No model forms a view about a vital sign. That is deliberate. A number's health should be reproducible, explainable in one sentence, and identical no matter who or what is looking at it. Not Yet Measured is a real and honest state, not a failure: a sign with no reading yet says so rather than showing a flattering zero.

Seeing the trend

Notion holds only the current state of each vital sign. The full measurement series lives behind Sera, which is why the interface cannot draw you a history. Ask her instead:

• "How have our volunteer hours trended this year?"
• "Chart the review backlog over the last six months."

She will pull the series and render it as a line chart in the conversation. If a sign has no history yet, she says measurement starts now rather than inventing earlier points.

Getting started well

• Three to five per circle. A circle with twenty metrics has none, because nobody reads twenty.
• Choose what would change a decision. If a number moving would not change what the circle does, it is a curiosity, not a vital sign.
• Name the seat. Attach it to the circle or role that is genuinely accountable for it, and let it stay there through every handover.
• Let quiet metrics stay quiet. A vital sign sitting On Track for a year is doing its job. The value is that you would know immediately if it stopped.

Key points

A Vital Sign belongs to a Circle or a Role, never to a person: it measures the seat, not the sitter, so the metric survives a handover and never becomes a performance file. Without a Target it is a standing health metric (a KPI); with a Target it is a key result (OKR mode). Each carries a Unit, a Direction (Higher is better, Lower is better, or Stay in range), a Baseline, a Current Value, Last Measured, a Cadence of Weekly, Monthly, or Quarterly, and How to Measure. Source is Manual, Sera-observed, or Auto (system). Passive tracking means Sera picks up explicitly stated numbers from meetings and emails and proposes them as updates; she never infers or estimates a measurement. Health is written nightly by pure arithmetic, one of On Track, Attention, Off Track, or Not Yet Measured, never by a model forming an opinion. Notion holds only the current value; the full measurement series lives behind Sera, so ask her to chart a trend. Start with three to five per circle, and write How to Measure before the first reading.
