Full-Cycle Product Manager

Move from a customer problem through discovery, validation, strategy, a build-ready PRD, launch, measurement, and the next product decision.

Don't just read it. Run it.

Start the work here, keep the important context together, and hand it off to people or AI.

Steps

  1. 1

    Define the Problem

    ID:OZA6

    Frame the customer problem before proposing a feature. Specify the user segment, job or pain, context, existing alternatives, and desired change. Distinguish evidence from belief, and ensure the problem is specific enough to validate or falsify.

    skill: github:phuryn/pm-skills @ analyze-feature-requests
  2. 2

    Discovery

    ID:Y52Q

    Explore the opportunity space before narrowing it. Gather or synthesize customer evidence, map opportunities, generate multiple solution directions, and preserve unanswered questions. Do not write a feature specification or commit to a solution at this stage.

  3. 3

    Map Assumptions

    ID:L35O

    List the value, usability, viability, feasibility, and go-to-market assumptions behind the leading options. Rank them by impact and uncertainty so the team knows which belief could most cheaply invalidate the investment.

    skill: github:phuryn/pm-skills @ identify-assumptions-existingskill: github:phuryn/pm-skills @ prioritize-assumptions
  4. 4

    Design Experiments

    ID:YJHN

    Design the smallest credible experiment for each critical assumption. Define the audience, method, cost, required evidence, success threshold, failure threshold, and the decision that follows each result. Prefer learning before building.

    skill: github:phuryn/pm-skills @ brainstorm-experiments-existing
  5. 5

    Product Strategy

    ID:0FUF

    Turn validated learning into a product bet. Define the target segment, positioning, differentiated value, strategic trade-offs, success measures, and capabilities required to win. State the hypotheses that still need monitoring after launch.

    skill: github:phuryn/pm-skills @ product-strategy
  6. 6

    Prioritize

    ID:JH7C

    Compare initiatives using impact, confidence, effort, dependencies, risk, and strategic alignment. Make the opportunity cost visible. Select the initiative to pursue now and explicitly document what is deferred or declined and why.

    skill: github:phuryn/pm-skills @ prioritize-features
  7. 7

    Write PRD

    ID:MISN

    Write an implementation-ready PRD: problem, users, objective, scope, requirements, non-goals, acceptance criteria, metrics, edge cases, dependencies, and unresolved assumptions. Ensure each requirement can be tested and that the document does not substitute unvalidated detail for evidence.

    skill: github:phuryn/pm-skills @ create-prd
  8. 8

    Launch Plan

    ID:S560

    Plan who receives the release, how it is introduced, what messaging and enablement are required, and which operational risks must be covered. Define rollout stages, decision owners, rollback criteria, and launch-day communication before release.

    skill: github:phuryn/pm-skills @ gtm-strategy
  9. 9

    Measure and Learn

    ID:LONA

    Set a baseline, metric tree, North Star metric, guardrails, and review cadence. Define the thresholds for continue, improve, pause, or stop. Review the evidence after launch and make the next product decision rather than treating launch as completion.
