Build a North Star Metric and decompose it into 3-5 controllable input metrics that sum/multiply to it — the Amplitude framework as a standalone build. Covers NSM selection criteria, the input-metric tree, finding the weakest input to focus on, and the anti-patterns (revenue/vanity NSMs). Makes a North Star *actionable* instead of a scoreboard. Used by metrics-architect.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> **Provenance.** great-pm-original, authored 2026-05-29, grounded in the > cited sources (Amplitude North Star Playbook, Open Practice Library, > Alex Morcillo). Host agent: metrics-architect. # North Star + Input-Metric Tree — making the one number actionable A North Star Metric (NSM) on its own is a **scoreboard**: it tells you the score but not which move to make. It becomes *actionable* only when decomposed into **3–5 input metrics** — the levers teams directly influence that *combine* (sum or multiply) to produce the North Star. Sean Ellis coined the NSM concept; **Amplitude formalized the input-metrics tree** that turns it from a vanity dashboard into a decision-making instrument. This skill builds both halves: select an NSM that survives the criteria, then decompose it into a tree the team can move. The defining property: a North Star expresses the **value customers get from the product**, framed as a *leading* indicator of business success — not the business success itself (that's revenue, a lagging output). The input tree is what lets a decentralized team find the *weakest input*, run experiments there, and check whether the North Star moved. …

How to install
mdr add vandanaajaydubey111/great-pm/north-star-input-tree@sha256:2d718be9772683c6The line at the top of this page pins the label git:20260721.86de099, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
