tool-foundation-sprint-basics
Day 1 morning move of a Foundation Sprint. Forces explicit team choices on target customer, important problem, team advantage, and competitors and alternatives. Produces a single coherent strategic frame that becomes the input to Day 1 afternoon Differentiation. Use after the sprint brief is signed and Day 1 morning is scheduled. Bundled artifact, not four separate decisions.

<!-- PM-Skills | https://github.com/product-on-purpose/pm-skills | Apache 2.0 --> # Foundation Sprint Basics Day 1 morning of a Foundation Sprint. The team makes four foundational choices explicit: who the product is for, what important problem it solves, why this team has a right to win, and what customers do today instead. The output is one coherent strategic frame, not four separable decisions. Family contract: [`docs/reference/skill-families/foundation-sprint-skills-contract.md`](../../docs/reference/skill-families/foundation-sprint-skills-contract.md). This skill is a member of `foundation-sprint-skills`. ## When to Use - Day 1 morning of a Foundation Sprint, after the brief is signed. - The team has sufficient customer and market knowledge (per readiness verdict) to make informed choices. - Each of the four sub-decisions is open or contested; the team has not pre-aligned on any of them. - The Decider is in the room and ready to sign off on the bundled output before lunch. ## When NOT to Use - The team lacks enough customer knowledge to choose a target customer or name an important problem. Run customer research or problem framing first; revisit when readiness criterion 3 pass

Where does this skill come from?
From product-on-purpose/pm-skills, a repository with 518 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
