Problem Definition

Scope

• Turning a vague idea into a crisp, testable problem definition
• Writing a shareable problem statement (1-liner + expanded)
• Capturing Jobs To Be Done (JTBD) and target segments
• Mapping current alternatives (including non-digital/analog) and “why now / why digital”
• Building an evidence + assumptions log to drive learning
• Defining success metrics + guardrails and clear scope boundaries

• “Write a problem statement for…”
• “We need to define the problem space / JTBD.”
• “We keep jumping to solutions; help us get clear on the real problem.”
• “Pressure to ‘do AI’ — verify there’s a real pain point first.”
• “Before we write a PRD, align on what problem we’re solving.”

• You already have an approved problem definition and need a delivery-ready PRD (use

  writing-prds

  )
• You need roadmap prioritization across many competing initiatives (use

  prioritizing-roadmap

  )
• You need to set company-level strategy/vision (use

  defining-product-vision

  )
• You’re doing deep research execution (recruiting, interviews, analysis); use this to frame what to learn, not as a substitute for research

Inputs

• Product/context + target user (or segment hypotheses)
• The triggering signal (customer quotes, data trend, stakeholder request, competitor move)
• The decision to make (e.g., invest now vs later; explore vs stop) + timeline
• Known constraints (tech/legal/privacy/compliance/capacity)

• Ask up to 5 questions from references/INTAKE.md.
• If still missing, proceed with clearly labeled assumptions and list Open questions that would change the decision.

Outputs (deliverables)

1. Context snapshot (product, user, trigger, decision, constraints)
2. Problem statement (1-liner + expanded) + why now
3. JTBD (primary job + key sub-jobs) + target segment notes
4. Current alternatives (including analog/non-digital) + gaps + switching costs
5. Evidence & assumptions log (what we know vs what we’re guessing)
6. Success criteria (outcome metric(s), leading indicators) + guardrails
7. Scope boundaries (in/out, non-goals, dependencies)
8. Prototype / learning plan (fast prototype + tests to de-risk)
9. Risks / Open questions / Next steps (always included)

Workflow (8 steps)

1) Intake + decision framing

• Inputs: User context; references/INTAKE.md.
• Actions: Clarify the decision, time horizon, stakeholders, and constraints. Capture the trigger signal (data/quotes/event).
• Outputs: Context snapshot.
• Checks: You can state the decision in one sentence (“We are deciding whether to… by <date>”).

2) Define the target user + situation (segment + context)

• Inputs: Context snapshot.
• Actions: Specify who experiences the problem, when it happens, frequency, and what’s at stake. If multiple segments, pick a primary and list others as secondary.
• Outputs: Target user + context bullets.
• Checks: The segment is specific enough that a researcher could recruit for it.

3) Write the problem statement (1-liner + expanded)

• Inputs: Target user + trigger signal.
• Actions: Draft a crisp 1-liner, then expand with symptoms, root causes (hypotheses), and impact. Include why now.
• Outputs: Problem statement section (using references/TEMPLATES.md).
• Checks: Statement describes the problem without implying a specific solution or technology.

4) Map current alternatives (including non-digital) + “why use this”

• Inputs: Problem statement.
• Actions: List how users solve this today (manual workarounds, spreadsheets, incumbents, doing nothing). Include at least one analog/non-digital alternative when relevant.
• Outputs: Alternatives table + gaps + switching costs.
• Checks: You can answer: “Why would a user give this the time of day vs their current way?”

5) Separate problem from solution (avoid the shiny object trap)

• Inputs: Alternatives + early solution ideas (if any).
• Actions: Capture solution ideas as hypotheses, not commitments. If “AI” (or any tech) is proposed, state the user pain point first and treat tech choice as an implementation detail.
• Outputs: Evidence & assumptions log (with test ideas).
• Checks: Each assumption has a proposed test and a confidence level.

6) Define success criteria + guardrails

• Inputs: Problem statement + evidence.
• Actions: Define measurable outcomes, leading indicators, and guardrails (quality, trust, cost, latency, support load, etc.).
• Outputs: Success metrics + guardrails section.
• Checks: Metrics are unambiguous and tied to the user’s desired outcome.

7) Visualize the end state + prototype a path to clarity

• Inputs: Success criteria + scope constraints.
• Actions: Describe what “done” looks like (user-visible end state). Create a fast prototype/experiment plan to validate the hardest assumptions before building.
• Outputs: End-state description + prototype/learning plan.
• Checks: The team can “see the end” and name the 1–3 biggest unknowns being tested.

8) Quality gate + finalize the pack

• Inputs: Full draft pack.
• Actions: Run references/CHECKLISTS.md and score with references/RUBRIC.md. Add Risks/Open questions/Next steps.
• Outputs: Final Problem Definition Pack.
• Checks: A stakeholder can review async and decide “proceed / pause / stop” without a meeting.

Quality gate (required)

• Use references/CHECKLISTS.md and references/RUBRIC.md.
• Always include: Risks, Open questions, Next steps.
