Introduction to Design

The word design is used constantly.

We talk about graphic design, product design, interaction design, fashion design, service design, interior design, game design, and web design. We use the same word to describe professions, processes, objects, and disciplines that can be very different from one another.

But what does it really mean to design?
Reducing design to the aesthetic appearance of an artifact is insufficient. Likewise, defining it simply as the ability to find solutions to problems risks being too generic: engineers, programmers, and architects also solve problems.
Design is, first and foremost, a discipline concerned with the conception and development of projects.
Designers imagine something that does not yet exist and progressively define what it should be like in order to meet specific goals, address the needs of particular audiences, and respond to given contexts and constraints.
The object of this process can vary considerably: a product, a poster, an interface, a service, an environment, an information system, or an experience. What these fields share is therefore not the type of artifact they produce, but the approach they take to designing it.

This book aims to develop a general understanding of design before exploring its many specializations.
Our starting point will inevitably be an apparently simple question: what is design?
We will attempt to understand it by distinguishing the design process from the final product and examining the relationship between artifact, user, and context. After all, an object is not designed merely to exist, but to be used, interpreted, perceived, or experienced by someone.

Design therefore also concerns the relationship established between people and what is designed.
From this definition, we will move on to the design process.
A project rarely emerges fully formed in the designer’s mind. It develops through observation, research, analysis, problem definition, exploration of alternatives, prototyping, evaluation, and progressive refinement of the solution.
Designing means continuously moving between problem and solution.
In some cases, the problem is clearly defined from the beginning. In others, it emerges through the research process itself. An apparently effective solution may reveal new difficulties, while a constraint may become a design opportunity.
For this reason, design should not be understood as a rigid sequence of stages, but as an iterative process in which understanding and designing continuously influence one another.
We will then explore the world of design.
Contemporary design encompasses numerous professional and disciplinary fields. Some focus primarily on physical artifacts, while others deal with communication, interfaces, services, environments, or complex systems.
Graphic designers, product designers, interaction designers, UX designers, service designers, and many other professionals work on different kinds of projects, yet share fundamental design principles and tools.
Understanding these differences helps avoid a common misconception: thinking of design as a single profession with a fixed set of skills.

Instead, design constitutes a broad field of practice made up of different, often overlapping specializations.
However, knowing design methods and disciplines is not enough to truly understand the designer’s work.
For this reason, we will also examine the practice of design.
Every real-world project is shaped by constraints.
There are budgets, deadlines, available technologies, production requirements, client interests, user needs, regulations, material limitations, and environmental or social consequences. A solution that appears ideal in the abstract may not be feasible or appropriate in a specific situation.
Design is therefore also the art of compromise.
Not in the sense of sacrificing quality, but of finding the best possible balance between different and sometimes conflicting requirements.

Designing means making choices.
And making choices means establishing priorities, accepting certain trade-offs, and taking responsibility for the consequences of one’s decisions.
Part of the book will also be dedicated to some of the best-known concepts in design.
Over time, design culture has produced principles, formulas, and rules that have become extremely popular. Expressions such as form follows function, less is more, and less but better are often quoted as though they were universal laws.
Instead, we will examine them as tools for thinking.
A design principle should not replace design reasoning. It should help us formulate questions, interpret problems, and evaluate solutions.
Understanding a principle therefore means knowing not only what it means, but also the context in which it is useful and the limits beyond which it ceases to be effective.
Finally, we will explore the boundaries of design.
Designers share certain areas of practice with other professionals, particularly artists, engineers, and architects.
With artists, they share languages, tools, and the ability to produce cultural meaning. With engineers, they share the need to solve problems and transform ideas into feasible systems. With architects, they share, in a particularly evident way, the project-based nature of their work.

Yet these disciplines are not identical.
Understanding their differences allows us to define more precisely what characterizes design while also recognizing the increasingly interdisciplinary nature of contemporary design practice.
The purpose of this book, therefore, is not to provide a definitive and unchanging definition of design.
It is to build a framework through which we can understand it.
To understand what it means to design. To understand how a project originates and develops. To navigate the different design disciplines. To learn to recognize constraints, compromises, and responsibilities. To critically interpret the principles of design culture and understand what distinguishes designers from professionals working in related fields.
Because learning design does not simply mean learning how to create artifacts.
Above all, it means learning to observe a situation, imagine how it could be different, and transform that possibility into a deliberate and thoughtfully developed design.
