Design Of Everyday Things by Don Norman

The Design of Everyday Things by Don Norman is an influential guide to understanding why some products are easy to use while others leave people confused and frustrated.

The book explores the relationship between people, objects and design.

Norman argues that when people repeatedly struggle to use an object, the problem may lie in the design rather than in the user.

From doors and switches to appliances and digital interfaces, everyday objects constantly communicate information about how they should be used.

Good design makes those instructions clear.

Poor design forces people to guess.

The Design of Everyday Things is especially valuable for designers, developers, engineers, product managers, entrepreneurs and anyone interested in understanding human behaviour.

Why Read The Design of Everyday Things?

The Design of Everyday Things teaches readers to look differently at ordinary objects.

Consider a door.

Should you push it?

Should you pull it?

If the user must stop and think about such a simple action, the design may not be communicating clearly.

Norman uses everyday examples to explain broader principles of usability and human-centered design.

Once you understand these principles, you may begin noticing good and bad design everywhere.

The Design of Everyday Things and Human-Centered Design

Human-centered design begins with understanding people.

Designers should consider how users think, behave and interpret information.

A product should not require users to understand the designer’s thinking.

Instead, the design itself should help users understand what they can do.

The revised edition of The Design of Everyday Things includes human-centered design as an important part of its discussion.

This principle applies to physical products as well as websites, applications and digital services.

Good Design Should Be Understandable

A well-designed product communicates its purpose.

Users should be able to identify what actions are possible.

They should also understand what happens after an action is taken.

If a user presses a button and nothing appears to happen, uncertainty follows.

Did the button work?

Should they press it again?

Good design reduces this uncertainty.

The Design of Everyday Things encourages designers to make important information visible and understandable.

Affordances and Signifiers

Two important ideas associated with The Design of Everyday Things are affordances and signifiers.

Affordances relate to the possible interactions between a person and an object.

Signifiers communicate where or how an action should happen.

For example, a door handle may suggest pulling.

A flat plate may suggest pushing.

Norman clarified and expanded his discussion of these concepts in the revised edition.

These ideas have become highly useful in product and interface design.

The Design of Everyday Things and Feedback

Feedback tells users what happened after they performed an action.

Imagine pressing an elevator button.

A light appears.

That light confirms that the system registered your request.

Without feedback, the user may become uncertain.

Digital interfaces work similarly.

A loading indicator tells users that something is happening.

A confirmation message tells them that an action succeeded.

The Design of Everyday Things highlights feedback as an essential part of understandable interaction.

Mapping Makes Products Easier to Understand

Mapping describes the relationship between controls and their results.

Good mapping feels natural.

Imagine four switches controlling four lights.

If the switches are arranged in the same pattern as the lights, users can understand them quickly.

If the relationship is random, people need to remember which switch controls which light.

The Design of Everyday Things shows why natural relationships between controls and outcomes can make products easier to use.

Stop Blaming the User

One of the most powerful ideas in The Design of Everyday Things is that designers should avoid immediately blaming users for mistakes.

A confusing system may create predictable errors.

If many people repeatedly make the same mistake, that pattern may reveal a design problem.

The designer’s responsibility is therefore not simply to make something technically functional.

The product should also help people use it correctly.

Norman’s broader argument emphasizes designing systems around human capabilities and limitations.

Human Error and Better Design

People forget things.

They become distracted.

They misunderstand instructions.

They occasionally press the wrong button.

Good design takes these realities into account.

Instead of expecting perfect behaviour, designers can create systems that reduce the likelihood or consequences of mistakes.

This approach becomes especially important when errors could be expensive or dangerous.

The Design of Everyday Things therefore treats human behaviour as a core part of the design process.

Make Important Actions Visible

Visibility helps people understand what they can do.

Important controls should not be unnecessarily hidden.

Useful information should appear when it is needed.

When users can easily see available actions and the current state of a system, they can make better decisions.

This principle is especially relevant in digital interfaces.

Complex menus and hidden controls may make even powerful software frustrating to use.

Understand the User’s Mental Model

People create mental models of how things work.

When a product behaves according to expectations, it feels intuitive.

When it behaves completely differently, users become confused.

Designers therefore need to consider what users already understand.

A familiar symbol can communicate information quickly.

An unfamiliar interaction may require additional explanation.

The Design of Everyday Things explores conceptual models as part of creating understandable products.

The Seven Stages of Action

Norman describes a framework often referred to as the seven stages of action.

It examines the process from forming a goal through performing an action and evaluating its result.

In simplified form, people:

1. Decide what they want.
2. Form an intention.
3. Determine an action.
4. Perform the action.
5. Observe what happened.
6. Interpret the result.
7. Decide whether the goal was achieved.

Understanding this process helps designers identify where users may become confused.

The Gulf of Execution and Evaluation

A user may know what they want but not know how to make a system do it.

That creates difficulty in execution.

Another user may perform an action but struggle to understand what happened afterward.

That creates difficulty in evaluation.

Good design reduces both problems.

The Design of Everyday Things encourages designers to make available actions clear and results easy to interpret.

The Design of Everyday Things for UX and UI Designers

Although the book discusses many physical objects, its principles apply naturally to digital products.

A website needs clear navigation.

An app needs understandable buttons.

An online checkout needs useful feedback.

A form needs clear error messages.

The technology may change, but people still need to understand what actions are available and what happened after those actions.

That is why The Design of Everyday Things remains relevant to UX and UI professionals.

Useful for Product Designers

Product designers need to think beyond appearance.

A beautiful product can still be frustrating.

A visually simple product can still be difficult to understand.

Good design combines appearance with usability.

The user should be able to accomplish their goal without unnecessary confusion.

Norman’s work is therefore useful for anyone responsible for designing tools, products or services.

Useful for Software Developers

Developers also influence usability.

Technical decisions can shape how users experience a product.

A system may work perfectly according to its code while still confusing the people using it.

Reading The Design of Everyday Things can help developers think beyond whether a feature technically works.

They can also consider whether users understand it.

Design Is About Solving Human Problems

Design is not simply decoration.

A product exists because someone needs to accomplish something.

Understanding that goal should influence the solution.

This is one reason The Design of Everyday Things has become influential across design and technology disciplines.

Norman connects design decisions with psychology and human behaviour rather than treating products only as physical or visual objects.

7 Powerful Lessons From The Design of Everyday Things

1. Design for Humans – Understand how real people think and behave.
2. Make Actions Clear – Users should easily see what they can do.
3. Provide Feedback – Every important action should produce an understandable response.
4. Use Natural Mapping – Controls should relate logically to their results.
5. Don’t Automatically Blame Users – Repeated mistakes may reveal design problems.
6. Create Clear Mental Models – Help users understand how a product works.
7. Design for Errors – Assume people will sometimes make mistakes and create systems that help them recover.
