About layers-user-needs

A library of user-needs techniques for product designers defining users, situations, and opportunities. It offers ways to frame and prioritize needs while distinguishing evidence from inference and assumption.

Key features

  1. 01Frame needs with job stories
  2. 02Identify functional, emotional, and social jobs
  3. 03Separate evidence from assumptions
  4. 04Prioritize by importance and service gaps
  5. 05Use workarounds as signals

Use cases

  1. 01Turn interview findings into needs
  2. 02Clarify goals across user types
  3. 03Find needs that remain unvalidated
  4. 04Prepare opportunities for product strategy

Install

From the project README

/layers-user-needs

Assumes /layers-intro has been loaded. This skill is a library of techniques, not a script — see "How to use these skills" there.

User needs are what we think users are trying to achieve, and why — an interpretation built on observed behaviour and domain knowledge, not a direct capture of reality. This layer sits between the messy raw material of observation and the deliberate decisions of the solution space.

The outputs here are opportunities: needs (what users want to achieve), pains (what causes friction), and desires (improvements they'd value). All three are valid — elicit all three.


The decisions this layer makes

  • Who exactly the users are whose needs we're defining — and in what situation
  • What jobs they're trying to do: functional, emotional, and social
  • Which needs are grounded in evidence, and which are assumptions
  • Which needs matter most, and why

If the needs are already clear and grounded, don't re-elicit them for the sake of it — take them to /layers-product-strategy.


Disciplines — what keeps needs honest

  • Need, not solution. "When I need a report, I want to export to CSV" is a solution. Push to the underlying need.
  • Strip the mechanism. If the "When" clause references your specific solution (your dashboard, your CSM, your weekly email), you're describing the current system, not the need. Re-state it independent of who or what serves it: what's true about the user at the moment they need this? The need follows from the state, not the mechanism.
  • The "When" must be picturable. Specific enough to see the moment it happens — triggered by an event, a feeling, a rhythm, or a threshold crossed. Push until it is.
  • Elicit emotional and social jobs, not just functional. They're chronically under-articulated even when they're shaping behaviour. Asking explicitly is usually what surfaces them. (Functional → interaction & model; emotional → surface tone/feedback; social → surface, sometimes strategy.)
  • Mark confidence: observed / inferred / assumed.
  • Workarounds are signal. A need real enough to motivate a spreadsheet or a workaround email is a strong one.

Techniques

Job stories are the default; the rest suit particular situations.

TechniqueUse it when
Job stories (JTBD)Default. When [situation], I want to [motivation], so I can [outcome]. Keeps solutions out; the "When" clause forces specificity.
User storiesThe team prefers role-based framing or an existing Agile workflow.
Top tasks analysis (Gerry McGovern)Large existing user base — identify which tasks matter most by frequency. Statistical, survey-based.
Persona + scenarioCommunicating to stakeholders who think in archetypes. Good for alignment; less precise for design.
ODI desired outcomes (Ulwick)Precise, measurable statements — "Minimize [metric] when [context]." Maps directly to opportunity scoring.
Surface hidden needsPrompts to find what's ignored: what users do before/after the moment you focus on; what they wish they didn't have to do; what a workaround currently serves.
Rough prioritisationOrder by importance × how poorly currently served. A need that matters and is badly served is a high-value opportunity. Keep it rough — precise scoring is strategy work.

Working with the designer

First settle who the users are and in what situation — not "users" but which type, when. If there's more than one distinct type with different needs, work them separately. Note the source (research, domain knowledge, or assumption); if it's assumption, mark it and plan to validate.

Then work the needs the designer raises through the disciplines above, and probe for hidden ones. Offer the technique that fits — job stories by default, ODI when measurability matters, top tasks when there's a large user base. Don't run a fixed sequence.

Capture only the residue: the prioritised needs with confidence ratings, the unprioritised-but-surfaced ones (so they aren't lost), gaps (probably-real needs not yet grounded), and any contradictions between user types. Keep it to what carries a decision.

These needs are the opportunities for /layers-product-strategy. If they're mostly assumed, consider /layers-observed-behaviour to gather evidence before building strategy on them.
