Product teams often carry quiet assumptions:

“Users will think like us.”
“This is basic, everyone knows this.”
“We can explain it if needed.”

These assumptions feel reasonable because they are grounded in our own context.

But user research repeatedly shows how fragile they are.

Dan Russell, a long-time search UX researcher at Google, once shared an example that illustrates this gap clearly.

While interviewing a bus driver preparing for a certification test, he observed her scrolling through a 100-page web document line by line, looking for a specific rule.

When he asked why she did not use the browser’s search shortcut, her answer was simple.

She did not know it existed.

To product teams, this sounds surprising. In real usage, it is common.

What feels “basic” is often not universal knowledge, but familiarity shaped by tech-savvy product teams’ tools, habits, and mental models.

That familiarity is context.

1. What “Context of Use” Really Means in Product Management

A product has no meaning on its own.

This sounds abstract, but it is one of the most practical ideas a product manager can internalize.

They only become meaningful inside a specific context of use.

1) Products Only Make Sense Inside Real Situations

Inside product teams, we often evaluate things in isolation.

But users never encounter products in isolation.

They encounter them:

A product that feels obvious in a design review can feel confusing, irrelevant, or even stressful in real life.

2) Why Asking Users What They Want Often Fails

“Let’s just ask users what they want.”

This sentence might sound user-centric. In practice, it can derail good discovery if it leads to solution shopping.

Surveys, interviews, and focus groups are filled with well-intentioned questions that produce confident answers and misleading conclusions.

The problem is not that users lie.

The problem is that people’s stated preferences often diverge from what they do in real situations.

(1) People Don’t Know What They Want

When users answer “what do you want?” questions, they usually do one of three things:

  1. Describe an ideal version of the world
  2. Describe a feature they saw somewhere else
  3. Rationalize their current behavior after the fact

None of these reflect how they actually behave in real situations.

This is not a user flaw. It is how human cognition works.

Most behavior is habitual, contextual, and reactive.

(2) Surveys and Focus Groups: The Limits of Opinion-Based User Research

Surveys and focus groups have built-in constraints.

As a result, they capture opinions, not reality.

This is why teams sometimes ship features that sound good in opinion-based research but underperform after launch.

(3) Goals vs Solutions: Distinguishing Goals from Proposed Solutions

One of the most common discovery mistakes is confusing goals with solutions.

When users say:

They are offering solutions. Solutions are shaped by what users already know.

They are limited by existing tools and mental models.

The real value lies underneath.

(4) What Behavior in Context Reveals Instead

Instead of asking what users want, PMs should focus on understanding behavior.

There are four questions that matter far more:

  1. What are users trying to accomplish?
  2. How are they doing it today?
  3. Where do they struggle or slow down?
  4. What workarounds have they created?

These questions reveal constraints, not preferences.

Constraints are where product opportunities live.

3) The Four Elements of Context of Use

ElementWhat It CoversWhy It Matters
UsersWho is using the product, including experience level, mental models, prior knowledge, and expectations.Users with similar demographics can behave very differently depending on what they know and assume.
TasksWhat the user is actually trying to accomplish, beyond what the feature or UI suggests.The product is often only a small step within a larger goal, which shapes how it is used.
EquipmentDevices, software, input methods, and workarounds involved in completing the task.Tool constraints strongly influence behavior and often explain unexpected user actions.
EnvironmentPhysical and social conditions such as noise, interruptions, pressure, or hierarchy.Even simple workflows can fail when the surrounding environment is not considered.

The context of use describes the full situation in which a product is used.

It is not just about the user. It is about the system around the user.

A useful way to break it down is into four elements.

(1) Users

Who is using the product?

Two users can look identical in demographics and behave completely differently because their mental models differ.

(2) Tasks

What is the user actually trying to do?

Not what we think they are doing. Not what the feature name suggests.

But the real goal behind their behavior.

Often, the product is only a small step inside a much larger task.

(3) Equipment

What tools are involved?

Constraints here shape behavior more than we expect.

(4) Environment

Where is the product used?

A “simple” workflow can break down completely in the wrong environment.

This leads to a core principle:

Usability depends on the context of use.
Without context, usability is a theoretical concept.

3) When Context Is Missing vs. When Context Is Clear

Decision AreaWhen Context Is MissingWhen Context Is Clear
Product DiscussionsFeature-based arguments such as “Users need this” or “Competitors have it”Discussions grounded in observed workflows and real situations
PrioritizationEverything feels important and trade-offs feel arbitraryContext narrows options and clarifies why something matters now
Decision DynamicsSeniority and intuition dominate decisionsObserved reality becomes the shared reference point
Execution QualityOverbuilding and slow execution due to unclear constraintsFocused execution shaped by real constraints
PRDs and RequirementsFeature lists without situational groundingRequirements framed as constraints and desired outcomes
Team TrustRepeated justification and debate over decisionsShared understanding and trust in judgment
Language Used“I think” or “This feels confusing”“We observed” or “This breaks the workflow”

When context is missing, teams rely on opinions, instincts, and past experience to fill the gap. Decisions still happen, but they often feel heavy, fragile, and difficult to defend.

When context is clear and shared, the nature of decision-making changes.
Teams stop debating what they believe and start reasoning from what they have observed.

Context does not remove disagreement. It changes what the disagreement is about.

Instead of arguing over preferences, teams discuss interpretations of the same reality.
That shift alone is often enough to unblock decisions, speed up execution, and build durable trust across the team.

Context as a Shared Language

One underrated benefit of context is that it becomes a common reference point.

Instead of saying:

Teams say:

This changes the tone of collaboration.


2. Contextual Inquiry: How to Understand Real User Behavior

Most product research is built on conversations.

Contextual inquiry is built on reality. Instead of asking users to remember, explain, or imagine, it places the PM directly inside the user’s real working context.

1) What Is Contextual Inquiry?

Contextual inquiry is a research approach where you:

The goal is not to validate ideas. The goal is to understand how work actually happens.

Not how users describe it. Not how teams assume it works.

Traditional interviews or surveys rely on memory and articulation. Contextual inquiry relies on behavior, environment, interruptions, workarounds.

This is why it consistently reveals things no survey ever will.

People rarely mention:

You only see those when you watch.

2) The Four Principles of Contextual Inquiry

Contextual inquiry is not “just shadowing.” It’s commonly taught with four core principles.

PrincipleWhat It Focuses OnWhy It Matters
ContextUnderstanding how work happens in the user’s real environment, including surroundings, sequences, and situational constraints.Without the real environment, critical constraints and workarounds disappear, leading to incomplete understanding.
PartnershipTreating the user as the expert and the researcher as the learner through observation and in-the-moment questioning.Real context emerges during real work, which increases the reliability of qualitative data.
InterpretationAssigning meaning to observed behavior by forming hypotheses and validating them with users.Prevents assumptions and overconfident conclusions that are detached from actual user intent.
FocusDefining a clear task, workflow, or problem space before observation begins.Without focus, observations turn into noise and insights lose decision-making value.

These four principles define how contextual inquiry is conducted, not what it produces.

Together, they ensure that observations remain grounded in real work, interpreted carefully, and collected with a clear purpose.

3) Why These Principles Matter

What Contextual Inquiry RevealsDescription
WorkflowsThe real sequence of actions users take, including detours and repetitions.
Tools & ArtifactsDevices, software, notes, and workarounds users rely on to get work done.
EnvironmentPhysical and social conditions that shape behavior.
PatternsRecurring behaviors and breakdowns identified across multiple users through synthesis methods such as affinity mapping.

By following these principles across multiple sessions, contextual inquiry moves beyond individual anecdotes and reveals structural patterns in how work is actually done.


4) Observation vs Interpretation in User Research

DimensionObservationInterpretation
DefinitionWhat you directly see or hear during researchThe meaning or explanation you assign to what you observed
NatureFactual, concrete, verifiableHypothetical, assumptive, needs validation
Example“The user copies data into a spreadsheet before submitting.”“The user does not trust the system.”
RiskLowHigh, if treated as fact

The same observation can support multiple interpretations. Without validation, interpretations easily turn into assumptions.

Example:

Observation

Possible interpretations

Until these interpretations are confirmed, they remain guesses.


5) Why Real User Behavior Feels Messy (and Why That’s Good)

Researchers often describe contextual research as uncomfortable.

This is the “complex and dirty truth” of real work.

But this mess is not a problem. It is the raw material of good product decisions. Clean narratives usually come later.

Reality comes first.


3. Contextual Design: Turning Research Into Shared Understanding

Contextual inquiry produces raw, messy data. On its own, that data is not very useful.

What makes it valuable is how it gets translated into shared artifacts that teams can reason about together. This is where contextual design comes in.

Without contextual design, user understanding stays implicit.

1) From Contextual Inquiry to Contextual Design

Contextual design is not a research method. It is a way to structure and externalize what was learned from contextual inquiry.

Its role is simple:

The output is not “a design.” The output is clarity.

Contextual design makes it explicit through artifacts such as workflow models, affinity diagrams, storyboards.

Teams can see:

This is the point where context becomes discussable.

2) Design Artifacts That Make Context Visible

Once context is externalized, conversations change.

Teams stop debating preferences. They start debating interpretations of the same reality.

Instead of:

Discussions sound like:

The argument is no longer about taste. It is about meaning.

3) Contextual Design as a Team Decision-Making Tool

Seen this way, contextual design is not owned by UX.

It sits between:

It allows teams to reason from the same evidence,

even when they disagree on solutions.


4. From Context to Decisions

Context is only valuable if it changes decisions.

Watching users work is not the goal. Shipping better products is.

The bridge between the two is a disciplined interpretation process.

TransitionWhat HappensKey Question
Observation → InsightConcrete behaviors are captured without assigning meaning. Initial hypotheses begin to form.Why does this behavior exist?
Insight → PatternRepeated insights across sessions reveal structural similarities.Is this recurring or situational?
Pattern → Problem DefinitionPatterns are framed as context-specific problems without suggesting solutions.What is breaking, and in what context?
Problem Definition → Solution FramingPossible solutions are evaluated against observed reality and constraints.Does this solve the observed breakdown?

1) Observation → Insight

Everything starts with observation.

An observation is something you can point to.

No meaning yet.

Just reality.

Insights emerge when you ask why this behavior exists.

This is where hypotheses form, but they are still fragile.

2) Insight → Pattern

One insight is interesting. Repeated insights form patterns.

Patterns answer questions like:

This is why contextual inquiry usually involves multiple sessions.

Patterns turn anecdotes into evidence.

3) Pattern → Problem Definition

Patterns should not jump directly to solutions. They should be framed as problems.

Good problem definitions:

Example:

“Users lose confidence before submitting because they cannot verify data without leaving the workflow.”

This is actionable without prescribing a feature.

4) Problem Definition → Solution Framing

Only after the problem is clear should solutions enter the room.

At this stage, solutions are evaluated against context:

Context becomes the filter, not taste.

Making Patterns Visible: Affinity Mapping

One practical technique PMs can use is affinity mapping, also known as the KJ technique.

This externalizes thinking and prevents premature conclusions and invites team participation.


5. Common Mistakes When Context Is Ignored

Most people agree that context matters. Many still break it in practice.

Not because they are careless, but because delivery pressure quietly reshapes behavior.

Mistake 1: Meeting Room Research

This happens when research is detached from reality.

The environment disappears.

So do interruptions, workarounds, and constraints.

The result looks clean and professional, but it is incomplete.

Context does not survive conference rooms.

Mistake 2: Starting With Summaries Instead of Observation

PMs love synthesis too much, jumping straight to:

often skips the most important step: shared observation.

When teams never see raw behavior, they trust conclusions less and debate more.

Summaries should come last, not first.

Mistake 3: Jumping to Solutions Too Early

This is the most common failure mode.

The moment a problem sounds familiar, PMs rush to fixes.

But premature solutions flatten context. They lock thinking before the problem is fully understood.

Mistake 4: The Myth of the “Representative User”

Personas can help, but creating a single “average user” often erases reality.

Real users:

Contextual research reveals variation.

Over-simplification hides it.

Faster synthesis, clearer narratives, and easier alignment might feel efficient, but speed without context creates false confidence.


6. In-Depth Interview: When Contextual Inquiry Isn’t Fully Possible

In practice, fully immersive contextual inquiry is not always feasible.

In many product teams, especially in B2B or internal tools, simply “watching users work” is not an option.

This does not mean context must be abandoned.

It means it must be approximated carefully.

How In-Depth Interviews Can Still Capture Context

In-depth interviews can be useful when they are designed to reconstruct real situations, not to collect opinions.

The key difference is how the interview is conducted.

Helpful interviews focus on:

Questions shift from:

to:

The closer the conversation stays to real behavior, the closer it gets to context.


Wrapping Up: Why Context Explains Product Success and Failure

Products do not exist on their own.

They are used

When these conditions are ignored or oversimplified, usability becomes theoretical.

What looks clear in a roadmap or design review often breaks down in real situations. This is why products that are “correct” can still feel irrelevant.
