What is prototyping in UX?
Prototyping is the process of creating early, simplified versions of an application or system to visualize and test concepts before full implementation. Prototypes can range from simple mockups to more advanced interactive models. This minimizes the risks and costs associated with making changes at later stages of software development.

Why does prototyping in UX matter?
This is a key stage of application development, which involves developing an early, simplified version of the system. The purpose of prototyping is to ensure that the design works in practice and meets users’ needs. Getting feedback at this stage is one of the cheapest ways to avoid costly mistakes and post-implementation fixes.
Prototyping helps project teams in three ways:
Evaluating initial ideas: Rapid prototypes allow for a realistic representation of ideas, which facilitates stakeholder understanding and acceptance of the project.
Increasing communication clarity: Prototyping tools with commenting features allow feedback to be shared and ensure that everyone involved has a shared vision of the project.
Optimize features and flows: User testing with a prototype helps uncover UX issues that were not apparent during planning, allowing necessary changes to be made quickly.(Here we encourage you to read the related article titled “Web Usability”)
UX prototyping vs. design thinking
Prototyping is an integral part of the design thinking approach – a human-centered methodology used to solve complex problems. Design thinking, through a combination of empathy, creativity and rational analysis, supports an innovative approach to designing solutions.
Design thinking consists of five stages:
1.Empathizing
2.Defining the problem
3.Generating ideas
4.Prototyping
5.Testing
Prototyping is the fourth stage of the process, where ideas and concepts are transformed into tangible models that can be tested and refined. Through this activity, teams can experiment with different solutions, gather feedback from users and iterate designs before they are fully implemented.
Prototyping in UX – types
Regardless of its type, prototyping is essential in the UX design process. It allows visualization and testing of concepts before full implementation of the product. Depending on the stage of the project and needs, different types of prototyping are used:
Paper prototyping
Paper prototyping is the simplest form of prototyping, which involves creating hand sketches on paper. It’s a quick and inexpensive way to do this, allowing you to effectively test different concepts and iterate ideas. As a result, they can be easily modified and improved on the fly.
Low-fidelity prototyping
Low-fidelity prototyping is a more advanced form, but still simplified. These types of prototypes can include basic interactions and screen transitions, but their functionality is limited. They are ideal in the early stages of a project.because they do not require a lot of work and resources.
High-fidelity prototyping
High-fidelity prototyping is the most advanced form of prototyping that is close to the final product. Such prototypes are fully interactive, with detailed interface elements and advanced animations. They allow UX and UI issues to be caught and resolved at an early stage, before the product is implemented.
The role of prototyping and UX Design in mobile, web application development
Prototyping contributes to better, more refined products that meet users’ needs and minimize the risk of costly mistakes at later stages of product development.
- Concept verification: Quickly assess the feasibility and quality of ideas.
- Gathering feedback: Gathering early feedback from users and stakeholders.
- Usability testing: Early identification and resolution of navigational and functional issues.
- Communication and collaboration: Understanding and visualization of the final product by project team members and other stakeholders.
- Cost and time savings: Early detection and resolution of problems.
- Interface integration and consistency: Testing and ensuring consistency of the user experience across different parts of the application.
Advantages of prototyping
Prototyping provides direct information about user interactions, which shows whether the product will work in reality. It also allows you to identify usability problems early on, allowing for low-cost and quick fixes. Prototypes help make informed design decisions by testing different versions and selecting the most effective solutions, leading to a market-ready product.
A tool used in creating UX prototypes
Figma
Enables real-time collaboration, allowing project teams to make changes and comment on the design at the same time. Its intuitive interface and rich feature set make it ideal for both beginners and advanced designers.
Adobe XD
Allows rapid prototyping thanks to its intuitive interface and integration with other Adobe applications such as Photoshop and Illustrator. Adobe XD also offers team collaboration features, making it easy to work in a group.
Axure RP
Allows you to create detailed and interactive prototypes. It is often used in more complex projects where complex interactions and logic are required. Axure RP also enables the generation of technical specifications, making it easier to communicate the project to developers.
FAQ – Frequently Asked Questions
What is an application prototype?
An application prototype is a preliminary version of a product that simulates its features and interface. It is used to test ideas, get feedback from users and detect problems early.
What is rapid prototyping?
Rapid prototyping is a method of rapidly creating early versions of a product. It allows for rapid iterations and revisions, which allows for efficient testing and refinement of concepts early in the project.
Why is prototyping important?
The process saves time and costs, preventing major changes in later stages, and ensures that the final product meets user needs.
What are the differences between low-fidelity and high-fidelity prototypes in UX?
Low-fidelity prototypes are simplistic, contain basic interactions and transitions, and their main purpose is to quickly test concepts. High-fidelity prototypes are advanced, interactive and close to the final product, allowing for more thorough UX and UI testing.
What are the benefits of prototyping in the design thinking process?
Prototyping in design thinking allows teams to experiment with different solutions, gather user feedback and iterate on designs at an early stage. This makes it possible to create innovative, customized solutions.
