When it comes to designing for the digital space, there are few components as critical as prototyping in the UI UX design pipeline.

But it sits in that grey area between conception and implementation; allowing designers to come up with a plan, test it, adjust it and see its results before the final consumer does.

But why is prototyping perceived as something so crucial? In this insight on Design Journal, let’s take you to its approaches, and proper usage to see how it is a foundational application to creating great UX.

What is prototyping in UI UX design?

In the context of UI UX design, prototyping cannot be described better than as the development of a first version of a product or feature.

It can vary from basic line drawings and layout drawings to computer aided cardboard models and sophisticated navigator prototypes.

Prototyping is aimed at refining and presenting them into more tangible apparition for the convenience of creatine, user and business objectives in order to avoid the wastes of time and efforts in the full development phases.

Prototypes are not the final product, but they serve several critical functions:

Testing Functionality: Guaranteeing that the design which has been incorporated offers the required functionality.
Facilitating Communication: Improving the communication between team members and external and internal actors.
Identifying Issues Early: Identifying issues before they are costly beyond repair.
Enabling Faster Iterations: The rapid and inexpensive modification of design.

Top 6 Prototyping Benefits

Enhanced collaboration

Prototypes can be used as a common ground among the teams since every designer, developer, or stakeholder will have a clear understanding of what has been created.

It is more effective than fixed design files or narrative descriptions since a team can work with a functional model.

Early problem detection

Identifying certain complications after development or sometimes even after launch is always disadvantageous.

Everyone agrees that developing a prototype helps teams solve usability problems, technical limitations, and design incompatibilities before making expensive alterations.

User-centric validation

A successful prototype can be used in usability testing, where designers can observe real users’ feelings as they interact with the products. This insulates the final design, helps meet users’ expectations, and correctly solves their pains.

Cost and time efficiency

This way, no major problems will require significant time and money during the later stages of the development process.

A well-designed prototype can eliminate some of the complicated phases of the development process, as developers have direct guidelines to follow.

Increased stakeholder buy-in

Stakeholders are more likely to be persuaded to accept the results when given a design prototype before implementation.

Instead of recognizing design theories or wireframes, the stakeholders can understand how the result will work. This puts them in a position to give good feedback that can be workable and help them make good decisions.

Reduced risk of failure

Thus, prototyping enables teams to create new concepts and ideas they would like to implement before the development process begins, and the final product will undoubtedly fail at launch.

Get the ideas into users’ hands as early as possible to avoid costly and time-consuming redesigns of these structures.

4 types of prototyping

Low-fidelity prototypes

Affordances observed from low-fidelity prototypes, such as sketches or wireframes, are layout-based. These are fast to make and can be perfect for first-stage concept development.

Medium-fidelity prototypes

Medium-fidelity prototypes depict more excellent details in the visuals and contain mere interactivity. These prototypes are built using the best Figma plugins, Adobe XD, or Sketch, giving a better look at the user interface.

High-fidelity prototypes

Real-life replicas are near final products because they contain design features with added interactivity.

They are quite relevant when conducting user tests and presenting to key stakeholders.

Code-based prototypes

For more complicated issues, fully functional prototypes implemented using HTML, CSS, and JavaScript can be used to determine the problem’s technical solvability and the interface’s usability.

Prototyping tools: Choosing the right one

Choosing the prototyping tool remains the prerogative of the project, as well as the expertise and phase of the design process. Some popular prototyping tools include:

Figma: Popular for its teamwork and interconnectivity and for being user-friendly.
Adobe XD: Enables easy connection with other Adobe applications.
Sketch: For instance, developers prefer Macs with a high user ranking among users for user interface design.
InVision: Good for building click-through prototypes.
Axure RP: Suitable for highly interactive and very elaborate prototypes.

Prototyping best practices for effective results

Define clear goals

When setting up the prototype, it is essential to define its goals.

What do you aim to do with your survey: are you experimenting with a particular interaction, checking the relevance of an idea, or collecting user responses?

If their purpose is being met as the goal, clarity makes that possible when designing the prototype.

Start simple

It has been established that using low fidelity prototypes helps get ideas and concepts off the ground. Only add details and interactivity to the screen as you progress through the design process.

Involve stakeholders early

Involve the stakeholders continuously during the generation of the prototypes. Their contribution guarantees that the design matches the strategic direction of the business and the probability of significant changes in the future are minimized.

Prioritize user testing

The place of a prototype doesn’t lie in the aesthetic design but in what it reveals about the users. Perform guerrilla testing to discover user hurdles and prove them right or wrong when making designs.

Iterate based on feedback

Prototyping is in some cases a cyclical process. Feedback as a guide for enhancing the completed design so that it could correspond to the user requirements and perceptions.

Use prototypes to drive decision-making

Prototypes are not unique only to testing, but can actually influence decision making in various ways as well.

Presenting a physical design does help bring to the table design direction and features, but more importantly, it does help stakeholders come to some conclusions about the design.

Design for different devices and platforms

With prototypes, it is easy to determine how designs will feature on different devices/platforms.

This proves that your product is future safe and graphic format and also the user experience is kept constant for mobiles, tabs and the desktop version.

Document and share feedback

Getting feedback is always good but must be done in a systematic way and then implemented.

Document the impressions that users, stakeholders and other team members make about the prototype so you are able to correct or alter them in the development process if necessary.

Real-world prototyping examples

Discover how these real-world prototyping examples bridge the gap between concepts and fully functional designs.

Airbnb’s rapid prototyping

Airbnb’s design team employs rapid prototyping as a core workflow component. By quickly creating interactive prototypes, they can simulate real-world usage and gather user feedback early in the design process.

This feedback loop enables them to validate their assumptions and refine their designs to ensure user-friendliness.

For instance, the team rapidly iterated on various prototypes when redesigning their booking flow, allowing them to identify pain points and streamline the experience before full-scale development.

This approach saves both time and resources while fostering a user-centered design philosophy.

Google’s design sprints

Google’s design sprints are structured, time-boxed frameworks aimed at solving complex problems through prototyping and testing.

These sprints typically last five days and involve cross-functional teams working to ideate, create, and validate solutions.

A notable prototyping example is Google Ventures’ use of design sprints to help startups refine their products. By focusing on prototyping as a key phase, teams can visualize potential solutions and test them with real users in a controlled environment.

This iterative process ensures that the final product aligns closely with user needs, reduces the risk of costly mistakes, and accelerates decision-making.

Spotify’s iterative design process

Spotify employs an iterative design process that heavily relies on prototyping to refine new features and enhance the user experience.

For example, when testing updates to their checkout system, the team develops prototypes in short cycles, gathers user feedback, and iterates based on the findings.

This approach allows them to identify usability issues, experiment with innovative ideas, and revisit the product with a fresh perspective.

By integrating frequent prototyping into their workflow, Spotify ensures that their features are functional and resonate with users’ expectations and preferences.

Dropbox’s paper prototyping

Dropbox has embraced paper prototyping to visualize and test ideas quickly, particularly during the initial stages of its design process.

This low-fidelity approach enables teams to sketch concepts, share them with stakeholders, and gather feedback without investing significant resources.

For example, when developing their file-sharing features, Dropbox designers used paper prototypes to experiment with different interface layouts and interactions.

These quick iterations allowed them to identify potential improvements early on, ultimately leading to a more polished and user-friendly final product.

The simplicity of paper prototyping also encourages creativity and collaboration among team members.

Conclusion

Prototyping is not the process of designing and building the UI/UX but a way of thinking that embraces trial, collaboration, and a focus on the user.

However, when designers spend more time and energy working on the prototype, they ensure they manufacture objects that exceed users’ expectations.

This is why no matter what kind of designer you are, a beginner or experienced, you should know how to create prototypes at your highest level.
