sound, but uneven
MARK
Good judgment is choosing what to do when the answer is not obvious.
Product work rarely gives you a clean answer. The data conflicts. Customers want different things. The loudest stakeholder may be wrong. Time and money are limited. MARK is a structure for seeing how well you make the call anyway, and explain why.
what MARK does for you
Build a credible story of how you judge.
Your MARK becomes a source-linked profile of the judgment your work demonstrates, where the evidence is still thin, and what would be useful to practise next.- 01
See what your work already shows.
Every claim links back to the answer or activity that produced it. You can inspect, challenge, or retract the read.
- 02
Know what to practise next.
MARK separates a real development edge from a criterion that is simply untested, so your next attempt has a reason.
- 03
Build a story others can inspect.
Over time, Your MARK becomes a source-linked record you can use in a 1:1, interview, promotion case, or team review.
//PL uses the MARK symbol wherever a judgment call can add to this record.
the answer, in one picture
Good judgment rests on four pillars. Each pillar has three criteria.
Map, Acuity, Resolve, and Know-how form MARK. The twelve criteria make each pillar specific enough to observe in a real answer, decision, or conversation. The radar shows the quality demonstrated so far; it is a changing shape, not a permanent score.one possible MARK

Acuity

Know-how

Each criterion has a precise definition and four behavioral levels. See all 48 behavioral examples ↓
what the shape can show
MARK exposes the pattern behind “good” or “bad” judgment.
A single average would hide the useful part. The shape shows where judgment is strong, uneven, absent, or still untested, and which imbalance could become consequential.a consequential blind spot
You can execute the wrong work very well.
Here Acuity, Resolve, and Know-how look strong, but Map is weak. The person may reason well after accepting the wrong agenda. MARK makes that imbalance visible.MARK is not a seniority ladder. A title from L1 to L7 changes the scope and stakes of the work, not the scoring rules. A senior title does not automatically produce a stronger MARK; evidence from judgment calls does.
how Your MARK grows on PL
Your MARK grows one Trace at a time.
PL can only learn from work it can actually see. A Trace is one source-linked observation from one activity, plus outcomes or human reviews you deliberately add later.how to read one Trace
Every criterion is read on two separate axes.
Quality asks: How strong was the judgment in this piece of work? Confidence asks: How much should we trust that this judgment will repeat?the complete system
MARK separates what you did, how well you judged, and how much the evidence deserves to be trusted.
quality · how well?
How strong was the judgment in this work?
- L1DevelopingDemonstrated with guidance.
- L2CompetentDemonstrated independently in familiar situations.
- L3ProficientDemonstrated in complex situations; helps others reason.
- L4ExpertChanges how a team makes this kind of call.
confidence · how sure?
How much should we trust that it will repeat?
- 01Self-reportedA starting hypothesis that PL has not observed.
- 02ObservedOne sourced activity shows the criterion.
- 03RepeatedSeparate work shows it in different situations.
- 04VerifiedOutcomes or credible reviewers support the interpretation.
where the work comes from
Use PL, then let separate activities and outcomes strengthen or challenge the read.
What PL does not do: it does not watch your Slack, WhatsApp, calls, or meetings. Work outside PL enters Your MARK only when you choose to add an outcome or ask a person to review it.
