What is Why-How Laddering?

Why-how laddering is a UX (user experience) research method that helps designers uncover users’ deep motivations and translate them into actionable design solutions. Designers systematically ask “why” to explore underlying needs and “how” to find practical implementations and move from surface-level actions (how) to higher values and reasons (why).

Researchers use why-how laddering in user interviews to uncover deep user insights. Find out how to get the most out of your user interview questions with Ann Blandford: Professor of Human-Computer Interaction at University College London:

How Does Why-How Laddering Help UX Designers?

The power of why-how laddering makes it an effective way for any researcher to explore what goals and motivations individuals have and consider how to meet or exceed them with a solution. It’s more involved than, for example, the decision-making process of someone who wants to buy a friend who likes gardening and cookery a birthday present of seeds for a herb garden. When researchers must drill down deeper into a matter—including to find the true nature and dimensions of that issue—they can use why-how laddering more consciously and purposefully.

The ladder structure involves two key questions: “Why?” and “How?”

  • To ladder “up” is to ask, “Why?” This question helps uncover the underlying reasons or motivations behind a user’s action or need, which leads to more abstract insights. To ask and obtain answers to this question moves from actions to values; it exposes deeper goals and motivations. Designers use it to understand user intent and ensure that features support meaningful outcomes.

  • To ladder “down” is to ask, “How?” This question explores the practical steps or features that can fulfill the identified needs, leading to more concrete solutions. This moves from abstract goals to specific tasks or interface elements. Designers use it to ground strategy in action and find how to implement a user-centered design vision.

When researchers alternate between these questions, they can build a ladder of insights that connects specific actions to broader motivations and move down to actionable design elements. They can cover a wide range of points to account for what should go in a solution—and why.

When designers understand the “why” behind user behaviors clearly, they can create and refine solutions that resonate on a far deeper level than if they were to assume or base decisions on what they see on the surface. For example, a user who sells crafts from their small shop might want a feature in a merchant app that saves time—and everybody likes to save time—but also prevents mishaps if they need to use one hand or take their eye off the screen to watch their storefront.

When UX researchers and designers ask “why,” they can get behind the user and discover points that can help them empathize better. For example, the small storeowner who sells crafts at a popular fair might be extremely busy and need to process payments while making sure nobody steals or damages their merchandise. Because many customers won’t use cash, this user needs a solution that can take several forms of electronic payment and confirm funds have transferred instantly. Another consideration may be that the storeowner is older and isn’t used to some cash applications—a potential stressor in a busy environment.

When a designer “climbs” above what’s on the surface with a why-how ladder, they can find the user’s desire to reduce stress and process payments quickly and properly. From there, they can prioritize features that not only save time but also promote ease and simplicity in a busy user scenario. So, they can craft a solution that’s ideal for a small businessowner who might be busy talking to customers, watching their store, and processing payments.

The process alternates between asking “why” and “how” to climb up or down the ladder of abstraction—whatever a designer or researcher needs to do to build empathy, clarify user goals, and ensure that features serve meaningful outcomes.

Why Do Designers Need To “Climb”?

Users rarely explain their needs clearly. It’s not because they choose to be difficult or obtuse; it’s just that they often have no concrete idea of the true nature of issues they face, let alone potential solutions to help them. Often, they’ll see their context and problem from an angle where they can’t help it. They might be too close to their everyday lives to be able to get the distance that an observant researcher can use to examine their scenario clearly. A user researcher applies qualitative research methods to access those parts of the user’s world and capture valuable insights—insights from which they can begin to consider how to create the best solution for the user’s needs.

It’s impossible to overstate how perspective can define a user’s world and “lock” them into a distorted view of their situation. To illustrate with an analogy, consider two people—a researcher and a user—as they go into a zoo’s aquarium. They stop in different parts of the viewing area where people go to see fish, rays, dolphins, and other water-based “residents” through underwater windows. These windows have curtains covering them. The researcher stands in one spot in the middle of the viewing gallery, while the user goes all the way up to a place by the curtain. Suddenly, the curtain opens. Standing farther back, the researcher admires the tank of stingrays. However, from the position right by the window, where one ray is hovering—with its underside hugging the glass—the user instantly sees a “ghostly face.” The user jumps back in alarm, and then smiles, realizing it’s the animal’s “nostrils” and mouth. Perspective is everything.

Up close, the underside of many rays can create the impression of a ghostly “face”—the real eyes are on the top of the animal.

In UX design, users might want a faster checkout or more personalized results, but the real value lies in why they want those things. Faster checkout might reflect a desire to save time or reduce stress, while personalized results might mirror a need to feel understood. Why-how laddering gives a structured questioning approach to this discovery process. It prevents teams from designing in a vacuum or over-focusing on features without asking what purpose they serve. It also bridges the gap between strategy and execution as it links big-picture goals to interface-level actions. Designers can get the best angles to be able to map user needs, align their designs with user intent, and sharpen focus on delivering meaningful experiences.

The process begins with a user behavior or design feature and asks “why” to uncover the deeper reason behind it. Then it flips to ask “how” to explore the practical steps a designer would take to fulfill that purpose. “How” helps designers break down abstract goals into tangible features. If a user’s goal is to feel more in control, a designer who climbs to “how” might discover the way to implement customizable settings or provide clear feedback mechanisms. The designer can break down abstract needs into concrete functions and connect everyday behaviors to high-level values. In short, it helps teams prioritize what matters.

For example:

  • Why does the user want to filter search results?

  • To find relevant content faster.

  • Why do they want to find content faster?

  • To feel in control and productive.

  • How can we support that feeling of control?

  • By offering intuitive, customizable filters and showing real-time feedback.

Each step reveals a deeper insight or a practical design direction.

What are Practical Uses of the Why-How Ladder in UX Work?

Why-how laddering helps researchers, designers, and other team members as they progress through their design process to gain the clearest view of what users need, why they need it, and—once they have those insights—how to delight them.

User Research

Why-how laddering improves interviews and usability studies; rather than stop at what users say they want, researchers can dig deeper:

  • “Why do you use that feature often?”

  • “Why do you avoid this screen?”

  • “How do you complete this task when the tool doesn’t work?”

A researcher who asks questions like these helps build a richer understanding of user behavior. The technique helps them reveal hidden assumptions and unmet needs that might not surface through other types of approach—such as surveys or closed-ended questions (with “yes/no” answers). For example, design teams can fine-tune their discoveries and embody their research in personas, fictitious representations of real users.

Learn how personas help designers gear better design solutions around what’s really important to their brand’s users, as William Hudson explains how design without personas falls short:

Journey Mapping

When a researcher or designer maps user journeys, laddering helps identify not only what steps users take but why each step matters, too. It highlights emotional triggers and decision points that influence the experience. This informs better prioritization and storytelling in the journey map.

Feature Prioritization

When teams work through their UX design process and product planning, they often face a flood of feature requests and ideas. Why-how laddering helps filter these requests by asking:

  • Why does this feature matter to the user?

  • How does it support a broader goal?

  • Does it align with our value proposition?

When they ask these questions, designers and teams can get distance on the problem, avoid bloated feature sets, and keep the product focused on user outcomes. Here’s how it might look in action:

  1. Feature: Auto-save notes.

  1. Why? To prevent users from losing work.

  1. Why? To reduce anxiety and frustration.

  1. Why? To create a sense of trust and reliability.

  1. How? Show visual confirmation of saving.

  1. How? Store versions for easy recovery.

  1. How? Allow users to restore changes easily without worrying about lost work.

This zigzag pattern ensures that every “how” traces back to a meaningful “why.”

Team Alignment

Cross-functional teams often work at different “altitudes”—and often can have substantially different perspectives. For example, a UX strategist will talk about values, while developers focus on execution. Why-how laddering bridges the gap. It shows how a user’s need for “autonomy” connects to a button that lets them undo actions, or how “saving time” leads to a pre-filled form.

In ideation sessions, the why-how ladder helps teams align quickly, as they use it to reframe vague problems (such as “We need better onboarding”) into actionable plans (“New users feel overwhelmed → they want confidence → we show quick wins in the first 3 screens”).

Facilitators can draw ladders on whiteboards or digital tools, and ask teams to start with known issues or design goals and then ladder up and down to find insights and potential solutions.

How to Use Why-How Laddering, Step by Step with Best Practices

Try this general set of guidelines to stand on the “rungs” of insight and move up and down to fine-tune more accurate insights.

  1. Identify a User Need or Behavior
    Start with a specific user action or requirement. For example, “Users want to receive notifications.”

  1. Ask “Why?”
    Explore the underlying motivation. “Why do users want notifications?” Maybe it’s to stay informed about important updates.

  1. Keep Asking “Why?”
    Delve deeper and see what comes up. “Why is staying informed important?” Perhaps it’s so users feel connected and in control.

  1. Reach the Core Motivation
    Continue until you reach a fundamental human need, such as the need for security or belonging. Sometimes it takes a few questions, and it’s here where the why-how ladder shares common ground with another helpful research tool in UX design: the 5 Whys method.

  1. Switch to “How?”
    Now you’ve reached the core motivation, it’s time to ask, “How can we fulfill this need?” For instance, “How can we help users feel connected?” This might lead to features like real-time updates or personalized content. Just as the 5 Whys method complements the “why” aspect in why-how laddering, another handy technique is like the “how” aspect—a method where researchers ask “how might we” (HMW) questions.

Explore “how might we” questions as a powerful way to complement research, in this video:

  1. Develop Actionable Solutions
    From the “hows” and the “whys,” you and your team can build the insights into design features that address both the practical and emotional needs of users.

Practical Example

Scenario: Users frequently use the “save for later” feature in a shopping app.

  • Why do users save items for later?

  • It’s because they want to compare options before they make a purchase.

  • Why do they want to compare options?

  • It’s to ensure they make the best choice and feel confident in their decision.

  • Why is confidence in decision-making important?

  • It reduces buyer’s remorse and increases satisfaction—no looking back from happier users and customers.

Now, switch to “how”:

  • How can we help users feel confident in their decisions?

  • Provide comparison tools, user reviews, and detailed product information.

  • How can we make comparisons easier?

  • Implement side-by-side comparison features and highlight key differences—get the information clearly well-positioned so users can minimize the time they’ve shelved the “saved for later” item.

Through this process, designers can create features that not only meet functional needs but address emotional drivers, too.

Best Practices

  • Be patient: Users might not immediately articulate their deeper motivations; they mightn’t be able to. So, allow the conversation to unfold naturally.

  • Avoid leading questions: Ensure that your questions are open-ended so users can give genuine responses instead of “yes” or “no”; use neutral language.

  • Document the ladder: Visual representations can help you identify patterns and connections between different user needs. Post-its or digital canvases work well to help track movement and spot patterns.

  • Collaborate: Involve cross-functional teams to gain diverse perspectives during the laddering process—non-designers can introduce ideas that a designer might not consider.

  • Start with real behavior or pain points. Don’t ladder from abstract concepts—keep it real, grounded in real-world perspectives, to save your team from building “castles in the sky.”

  • Ask “why” to go higher, but stop when the answer becomes too vague. Once you reach a core value (e.g., trust, ease, confidence), don’t overreach; you’re at the top rung.

  • Ask “how” to explore solutions. This keeps the team grounded—take the time to come back from higher “up” and explore how to meet users’ practical needs and problems.

Special Considerations for Why-How Laddering

  • Don’t over-interpret answers: Not every “why” leads to a universal truth, so use context.

  • Don’t force the ladder: If you (or anyone else on the team who’s asking questions) can’t go higher or deeper or the answer becomes repetitive, stop; you’re either at the most extreme level or on the wrong piece of research ground. If it’s the latter, consider a new ladder.

  • Don’t design only from the top: Don’t skip the “how” steps—big ideas need real execution to bring them down to “user level”; otherwise, they’ll stay on that top rung and serve nobody.

  • Don’t forget feelings: Laddering should reveal feelings, not just tasks—bring it back to the human being and what user-centric meaning is all about. Trust in your well-made personas for this.

To get back on the “ladder” for another example of how this works, imagine a team who’s designing a task management or productivity app: a user says they want task reminders.

Instead of building reminders outright, the team ladders with questions and insights relevant to the app’s users:

  • “Why do you want reminders?”

  • “To avoid missing deadlines.”

  • “Why does that matter?”

  • “It helps me feel on top of my work.”

  • Why is that important?

  • “It lowers stress and keeps me feeling confident.”

Then they go down:

  • “How might we support that confidence?”

  • Let users set their own reminder timing.

  • Offer morning summaries of due tasks.

  • Highlight what’s done, not just what’s pending, to build and boost morale and keep momentum high.

Note how the final feature set does more than remind—it supports emotional needs like control and reassurance and plants the feature on solid ground where users can sense it. Users will appreciate that practicality and how it makes them feel. It’s not “floating” above their everyday experience as something the designer assumed they wanted; instead, it speaks to them and is totally relevant to their needs.

Image of a ladder as a viewer faces from below.

A ladder can offer many points of view; just be sure to look carefully at all the branches of ideas—and between them—as you proceed up or down, and keep your balance. (Note: you may have to build your own “guard rail” to prevent “mishaps”).

Overall, why-how laddering helps UX designers stay grounded in what users truly need while being able to get heightened perspectives on the “real deal” of a user’s issue or need. It uncovers deep motivations and highest desires, and ties them to actionable designs. The method sharpens research, aligns teams, and helps ensure that every feature supports a clear purpose—one users will recognize and feel the brand speaking to them through.

The system of inquiry works because it means to ask the right questions in the right order. It doesn’t assume that the team using it knows what users want or the users know what they want—this process is about seeking to understand. When designers and their teams use why-how laddering consistently, they can help themselves prototype, test, refine, and release products that feel intuitive, focused, and meaningful.

Users will rarely know what they want in exact terms—let alone be able to tell designers. For their part, researchers and designers can use the ladder mindfully, and neither get stuck staring at assumptions about features nor trapped wondering into the space above the highest “rung.” Few users will be interested in lofty concepts or philosophies that designers can’t translate to something concrete for them. Because this method links purpose to action, it keeps design human-centered, not feature-driven—and that, at its core, is what great UX design always aims to achieve.

Questions related to Why-How Laddering

What is Why-How Laddering in UX design?

Why-how laddering helps designers connect a user’s goals (“why”) to specific features or actions (“how”). This technique breaks down abstract motivations into practical design elements. It starts by asking why a user wants something, then explores how to fulfill that need in the context. You repeat the questions to climb up or down the “ladder” of reasoning as you need to.

This method comes from laddering interviews in psychology, where researchers explore people’s core values. In UX (user experience) design, laddering reveals what users truly care about and shows how features can support those values. It’s a technique that supports goal-directed design, as it maps features to real user intentions from early on. It clarifies feature priorities and ensures designs reflect meaningful user goals.

For example, if a user says, “I want to check my bank balance,” ask “Why?” The answer might be “To avoid overdraft.” Then ask “How?” to find simple, real-time updates as a solution.

Why should I use why-how laddering during UX research?

Why-how laddering helps you uncover what drives users and how to meet those needs. When you climb the ladder—up and down—you can move beyond surface-level responses by tracing goals back to their root causes and forward to actionable steps. It reveals patterns in user motivations and links them directly to design opportunities for you and your team to seize. Do it well and you can bridge the gap between strategy and execution; mapping “why” (the user's deeper goal) to "how" (concrete features or tasks) so you can build experiences that resonate on a human level.

For example, during interviews you can use this method to dig deeper. Ask “Why is that important?” or “How would that help?” to gain meaningful insights. So, if a user says, “I need notifications.” Ask why—they might say, “So I don’t miss updates.” Ask how—that could mean “push alerts for key actions.”

What’s the difference between the “why” and the “how” in laddering?

In why-how laddering, the “why” reveals a user’s deeper motivation—what they value or want to achieve. The “how” uncovers specific actions or features that support that motivation. Each step up the ladder asks “Why?” to find meaning, while each step down asks “How?” to turn that meaning into solid approaches and solutions.

The “why” exists in the emotional or strategic space. It answers, “Why does this matter to the user?” The “how” lives in the practical realm. It answers, “How can we make this happen?” Without the “why,” you risk building features no one needs. Without the “how,” you won’t be able to turn insights into usable experiences.

For example, for a user who wants to track their fitness, you ask, “Why?” They say, “It’s to stay healthy.” Then you ask, “How?” to get to what they want to see: daily activity graphs and goal reminders.

Explore some helpful additional angles on how laddering can work best for you, in our article Laddering Questions Drilling Down Deep and Moving Sideways in UX Research.

When should I apply why-how laddering in the UX design process?

It’s wise to use why-how laddering early in the UX design process, especially during user research, discovery, or ideation. This method uncovers user motivations long before you lock in features or wireframes. It ensures that your design decisions support real goals—not just assumptions.

Laddering fits best during interviews, empathy mapping, journey mapping, or when you’re refining user personas. Teams also use it to prioritize features and align stakeholder decisions with user needs. It guides ideation in how it helps connect what users care about with practical solutions.

Start each project by laddering key user goals; it helps you filter out noise and build features that matter.

Get a firm footing on solid research ground and learn how to empathize with users so you can give them what they really want in a design solution.

How do I start a why-how laddering interview with users?

Begin with a specific behavior or product experience. Ask the user what they did, then ask “Why did you do that?” to uncover motivation. Once they explain, ask again, “Why is that important?” to climb toward deeper goals. Reverse direction by asking “How would that help?” to help identify practical solutions.

This cycle—what, why, why, how—helps you build and use a ladder between values and actions. Keep the tone conversational. Don’t ask yes/no questions. Listen for emotional cues or value-laden words like “important,” “helpful,” or “need”; then, dig into those.

Try this script structure:

  1. “Tell me about the last time you [used the product].”

  1. “Why did you do that?”

  1. “Why is that important to you?”

  1. “How could we help with that?”

For example, a user says, “I checked the app for delivery status.” Ask, “Why?” They say, “To know when to be home.” Ask, “Why is that important?” They reply, “So I don’t miss it.” Ask, “How could we help?”—and they may suggest real-time driver tracking.

How do I go from surface-level behavior to deep user goals using laddering?

Start with a clear behavior, then ask “Why did you do that?” The first answer reveals a functional reason. Ask “Why is that important?” to get to emotional or value-based goals. Keep asking “Why?” until the answers shift from actions to feelings or beliefs. This tells you you’ve reached a deep goal.

You move from what users do to why it matters to them. These deeper insights reveal what drives decisions—vital concepts like trust, control, or peace of mind. You can then design solutions that connect directly to those needs.

Stay attentive and stop laddering when the answer reflects identity, emotion, or personal meaning. Then, flip the gears into reverse and ask, “How can we support that?” For example, a user says they “save favorite items.” Why? “To find them later.” Why’s that important? “So I don’t waste time.” Why? “Because I feel overwhelmed.” That final layer shows the emotional driver, and where your design opportunity might come in handy.

Discover essential truths about user behavior and insights into how the people you design for may think about their unique contexts and wider aspects of their world.

How does laddering help build user personas?

Laddering uncovers the “why” behind user actions, and the reasons it exposes help add depth to user personas. Rather than list surface traits or tasks, laddering helps you reveal values, emotions, and motivations—insights that help you shape richer, more relatable personas that reflect real human needs, not just behaviors. For example, two users might use the same feature, but one seeks convenience, while the other values control. Laddering helps you spot that distinction.

When you ask mindfully repeated “Why?” questions during interviews, you can expose what users truly care about. This helps you understand and group users not just by what they do, but by why they do it. From there, you can weave empathy into your personas and guide design decisions with purpose. Use laddering insights to add sections like “core motivations” or “emotional needs” in your personas. These layers turn personas into strategic tools, not just role descriptions.

Want to know more about personas and how to use them effectively? Personas and User Research: Design Products and Services People Need and Want will show you how to gather meaningful user insights, avoid bias, and build research-backed personas that help you design intuitive, relevant products. You’ll walk away with practical skills and a certificate that demonstrates your expertise in user research and persona creation.

How does laddering connect user needs to product features?

Laddering creates a direct path from user motivations to the features that meet them. It starts when you ask why users want something—and uncover deeper needs like trust, speed, or peace of mind. Then you ask how to fulfill that need—and identify specific features or actions that support it.

This approach ensures your product doesn’t just work—it resonates and speaks to the people who’ll use and (ideally) love it, too. When you tie features to real human goals, you build experiences users value and appreciate your brand for listening to them. It helps prioritize what to build by linking functionality to emotional impact, too.

Be sure to map each feature to a laddering insight. If you can’t answer “What user need does this serve?”—you likely don’t need that feature. For example, if a user wants delivery tracking, your “Why?” questions reveals it’s “to feel in control.” From there, you move to “How?” and find a “live map with ETA updates” is a good design decision. The map isn’t just a tool—it delivers emotional reassurance to users.

Explore the treacherous territory of feature creep and how to avoid it in our article Feature Creep, the Bane of Our Existence.

How do designers use why-how laddering in brainstorming sessions?

Designers use why-how laddering in brainstorming to anchor ideas in real user needs. They can start with a user goal—then ask “Why does this matter?” to reach deeper motivations. With that insight, they ask “How can we solve this?” to generate feature ideas that respond to those motivations.

This keeps brainstorming focused and meaningful—a brainstorming session can generate a vast multitude of ideas. Laddering helps filter out flashy but irrelevant concepts and encourages ideas that align with users’ values. Teams often create visible ladders—on whiteboards or sticky notes—to trace ideas from insight to implementation.

So, try to use a ladder as a framework in brainstorming. Start with a user quote or pain point. Climb up for motivation, then work down to generate solutions. This can help your ideas hit both heart and function.

Take shelter with a strong understanding of brainstorming and how to direct it towards outcomes that can lead to great design solutions.

What are common mistakes when doing why-how laddering?

Designers often make mistakes by rushing the process or stopping too early. One common mistake is accepting surface-level answers without digging into real motivations. Another is steering users toward expected answers instead of listening openly. In some interviews, interviewers end up flipping too quickly between “why” and “how,” which breaks the logical flow.

Other designers or researchers overuse laddering, pushing too far until the user feels interrogated; people can shut off when they start to become irritated from what may feel like “pushy” or relentless questioning. Some designers err by jumping straight to solutions without fully understanding the need. Also, failing to record or map the ladders clearly can result in lost insights and weak design links.

So, it’s wise to ask no more than three “why” questions in a row, and listen for emotional or value-based cues. Stop when users reveal meaning or identity. Then pivot to “how” for ideas.

What’s the difference between laddering and the 5 Whys technique?

Laddering explores both “why” and “how” to connect user values to design features. The 5 Whys technique focuses only on root causes by asking “Why?” five times to solve a problem. While both dig deeper, laddering helps designers uncovers emotional drivers and turns them into actionable ideas. The 5 Whys stays analytical, and it’s ideal for fixing process or system issues where a chain of causes and effects obscures the true “culprit.”

Laddering works well in UX research because it climbs toward meaning and descends toward solutions. The 5 Whys approach works best in operations or engineering, where a single root cause explains a failure, although designers can leverage it to great effect especially for more complex problems.

Explore how the 5 Whys approach can help reach insights to get behind users.

Vanden Abeele, V., & Zaman, B. (2009). Laddering the user experience. In Proceedings of the Workshop on User Experience Evaluation Methods in Product Development (UXEM’09), INTERACT 2009, Uppsala, Sweden.

This foundational paper introduces "User Experience Laddering," an adaptation of the laddering technique from consumer research, grounded in Means-End Theory. The method involves in-depth interviews where participants identify product attributes and are subsequently probed with "why" questions to uncover underlying consequences and personal values. This approach helps researchers and designers understand how specific product features contribute to meaningful user experiences. By mapping these insights into Hierarchical Value Maps, the method provides a structured framework to inform user-centered design decisions. Its emphasis on connecting product attributes to user values has made it a significant contribution to UX research methodologies.
