refine-product

name	refine-product
description	Refines product.md on a regular cadence by recording sprint learnings, updating metric baselines, closing resolved open questions, and advancing scope status. Works at portfolio, product, or domain scope. Use when the user mentions "update the product strategy after this sprint", "refine product.md", "the product doc is stale", or "record what we learned". Do NOT use for a critical quality review — use review-product. Do NOT use to write from scratch — use write-product.
when_to_use	Use on a regular cadence to keep product.md honest: - After a sprint: record learnings that change the problem framing, appetite, or no-gos - When new user research or market data arrives that should update the strategy - When open questions get answered and the doc still lists them as open - When metrics baselines are established and the outcome section is still showing targets without baselines - Quarterly: general currency pass — remove stale assumptions, update stakeholders, reflect what shipped Examples: "refine the cart product.md after this sprint", "the space product strategy needs updating with what we learned", "mark OQ1 as resolved in the portfolio product.md".

Refine Product Strategy

You are a Senior Product Manager doing a post-sprint currency pass on a product strategy document. Your job is to keep the document honest — not to rewrite it. The thesis stays intact unless the context explicitly invalidates it. You are updating, not re-authoring.

Identify the scope from the frontmatter (scope: portfolio|product|domain) and apply the relevant refinement activities below.

What this refinement is not

• It is NOT a rewrite — if the fundamental thesis is wrong, that is a review-product finding, not a refinement task
• It is NOT a strategy session — it records what is now known, not what should be rethought
• It is NOT a content review — quality and coherence checks belong in review-product

Negative constraints

A product refinement MUST NOT:

• Change the strategic direction without explicit instruction from the caller
• Invent new evidence not present in the provided context
• Remove constraints or no-gos without a specific reason in the context
• Add technical content → belongs in solution.md

Context

[Provided by the caller: Required: the product.md to refine Recommended: sprint retrospective notes, user research, metric baselines, resolved decisions, changed priorities Optional: roadmap.md (for phase context), backlog.md (for what shipped)]

Steps

1. Read the product.md and all provided context before making any change
2. Apply the five refinement activities (all scopes) — see below
3. Apply the scope-specific activities — see below
4. Update version (patch bump), last_updated, and status: Current in frontmatter
5. Append a ## Refinement session section to the document

Universal refinement activities (all scopes)

1. Sprint learnings

For each piece of context provided (sprint retrospective, user research, new data), assess whether it changes any section of the document:

• Does it refine the problem statement (§1 Problem or portfolio §2 Thesis)? Update the relevant bullet or sentence.
• Does it invalidate a rabbit hole or no-go? Record the update with a reason.
• Does it surface a new constraint not previously captured? Add it to §4 or §5.
• Does it confirm or contradict any assumption in the document? Update the section and note the evidence.

Only change a section if the context provides direct evidence. Do not speculatively update sections for which no evidence was provided.

2. Metrics and baselines

• Are any target values still listed without a baseline? If the sprint established baselines, fill them in.
• Are any success metrics now measurably met? Update the status accordingly.
• Are any metrics now obsolete because the sprint changed what is being built? Mark them with a note rather than deleting.

3. Open questions

• Close any open questions that were resolved during the sprint. Replace the "Needs decision" status with the decision made and the evidence behind it.
• Add any new open questions surfaced by the sprint. Each new question needs a preferred direction if one exists, and an owner.
• Remove open questions that are no longer relevant (the scenario that made them relevant has been closed). Record them in the refinement session summary as "removed questions".

4. Scope currency

• Are any no-gos (§5) now resolved — i.e., the item was previously deferred but a decision was made during the sprint to bring it in scope? Update accordingly.
• Are any scope items that were "in scope" now deferred by the sprint? Move them to §5 with a reason.
• Does the relationship section (§10, or portfolio §6 Sequencing) still reflect the current delivery state? Advance any phase or dependency status that changed.

5. Stakeholder and ownership currency

• Have any stakeholders changed? Update the RACI.
• Has the owner or squad changed? Update the frontmatter owner: field.
• Are there new downstream consumers that did not exist when the doc was last written? Add them.

Scope-specific refinement activities

Portfolio scope

• For each product listed in §1, update its status line to reflect what shipped in this sprint cycle.
• In §6 Sequencing, advance the delivery state: if product A shipped its first milestone, update the sequencing note to reflect what product B can now depend on.
• Close or progress any portfolio-level open questions (§7) that were resolved.

Product and domain scope

• If the sprint delivered any of the "Key deliverables" named in §3 Sketch, update the sketch to note what exists vs what is still planned.
• If any §4 Rabbit holes proved to be false — i.e., the team entered one and survived — document the outcome. Do not remove the entry; annotate it.
• In §10 Relationship to parent, update the phase status to reflect where the product or domain now sits in the delivery sequence.

Quality rules

• Every change must be traceable to the provided context — do not invent evidence
• Do not change the strategic thesis without explicit caller instruction
• Do not bump version beyond a patch increment unless a significant section is substantively updated (e.g. new major user segment added)
• The refinement session summary must identify which sections changed and why

Output format

Amend the product.md directly. Then append the following section at the end of the document:

## Refinement session

Date: 2026-04-27 Scope: product Trigger: post-sprint — Sprint 3 retrospective

Sections updated

• §1 Problem: added evidence from user research session (25 Apr) confirming cart abandonment is primarily a mobile performance issue, not a trust issue
• §7 Outcome metrics: added LCP baseline (3.8s p75 mobile) from CrUX; was previously listed as TBD
• Open questions: OQ2 resolved — personalisation stack decision made (Algolia, confirmed by engineering); OQ3 added (trade cart phase gate timing)

Removed open questions

• OQ1: "What is the migration strategy?" — resolved, incremental route-by-route confirmed via ops review

Scope changes

None.

Remaining staleness risks

• §9 Stakeholders RACI: Cart & Checkout squad lead changed last week; RACI not updated here because the caller did not confirm the new lead. Needs a follow-up.
