The toolkit
Don't just read the frameworks — run them.
Thirteen live instruments, ported straight from the skill's own logic: the arithmetic is the easy part, so each one shows the judgment call the number can hide. Edit the inputs; the verdict updates as you type.
Prioritization
RICE scorer with the kill rule
Rank a backlog by Reach × Impact × Confidence ÷ Effort — and watch confidence act as an honest discount, not a fudge factor. Anything under 50% is a kill, not a low rank.
The RICE scorer needs JavaScript to run. The framework it computes — and its failure modes — are written up in the Prioritization guide.
GTM · Positioning
Positioning statement builder
Fill the five Dunford components in order; the one-line statement assembles live. Then run the substitutability test — swap a rival's name in and see if it still reads true.
The positioning builder needs JavaScript to run. The five-component derivation is in the GTM guide.
Pricing
Pricing & EVC calculator
Economic Value to Customer sets the ceiling: next-best alternative plus the value of your differentiation, minus switching cost. Capture a share of it, then lay out Good / Better / Best.
The EVC calculator needs JavaScript to run. The pricing logic and tiering ratios are in the Pricing guide.
Calibration
Blind-spot tagger
Match the ritual to the stakes: the full five-point check for high-stakes, irreversible calls; a one-line tag for routine ones. It writes the decision tag for you.
The blind-spot tagger needs JavaScript to run. The confidence ladder and the check itself live in the Decision heuristics guide.
The router
Task router
Tell it what you're trying to do; it routes to the one discipline that owns the answer — and links you straight into that guide. Picking one framework is the judgment; dumping all of them is the tell.
The task router needs JavaScript to run. Every discipline it routes to is browsable from the Field Guide hub.
Prioritization · sequencing
WSJF / CD3 sequencer
Cost of Delay decomposed into User-Business Value + Time-Criticality + Risk-Reduction/Opportunity-Enablement, divided by duration. The value is forcing the conversation, not the digit — and halving duration doubles CD3.
The WSJF sequencer needs JavaScript to run. Where it sits among the eight methods is in the Prioritization guide.
Discovery · Ulwick ODI
Opportunity score
Importance + max(importance − satisfaction, 0) — added, never multiplied. A well-satisfied need scores low no matter how important it is, so high-importance + high-satisfaction reads as the trap it is.
The opportunity scorer needs JavaScript to run. The JTBD-aligned method is in the Discovery guide.
Metrics · growth accounting
Quick Ratio + retention bands
(New + resurrected) ÷ churned MAU — below 1 you leak faster than you fill, no matter how strong acquisition looks. Then read D1/D7/D30 and DAU/MAU against directional benchmark bands.
The Quick Ratio gauge needs JavaScript to run. The growth-accounting identity and the benchmark bands are in the Metrics guide.
Metrics · product-market fit
Sean Ellis PMF meter
≥ 40% of users answering “very disappointed” without the product signals product-market fit. Below the bar, more acquisition just fills a leaky bucket — fix retention first, don't scale.
The PMF meter needs JavaScript to run. The probe and its premature-scaling caveat are in the Metrics guide.
Growth · loops over funnels
Growth-loop amplifier
A viral loop's gain K = invites × accept-rate; steady-state amplification is 1 ÷ (1 − K). A loop that leaks (K ≪ 1) is a funnel wearing a costume — the leverage is the accept step, not invite volume.
The growth-loop amplifier needs JavaScript to run. The re-feed math is in the Growth & PLG guide.
Strategy · market entry
TAM / SAM / SOM builder
Size the market bottom-up — accounts × reachable share × obtainable share × price, summed over segments — not as a top-down “1% of a $10B market.” That framing is a wish, not a plan.
The TAM/SAM/SOM builder needs JavaScript to run. The bottom-up entry sequence is in the Strategy guide.
Strategy · decision matrix
Build · Partner · Buy
Weight the criteria, score each path 1-5, read the weighted totals. Build buys control at the cost of time; Partner buys speed at the cost of ownership; Buy buys both but carries integration risk.
The Build·Partner·Buy matrix needs JavaScript to run. The market-entry decision it sits in is in the Strategy guide.
Prioritization · Kano
Kano classifier
Answer the paired functional / dysfunctional question for each feature; the standard Kano table reads off Attractive, Performance, Must-be, Indifferent, Reverse or Questionable. Delighters decay into expected — so re-survey.
The Kano classifier needs JavaScript to run. Where Kano earns its keep among the methods is in the Prioritization guide.
