*Imagine stepping into a new gym for the first time.* 

You're greeted by staff who give you a tour of the facility, showing you around the various workout areas and amenities. They introduce you to the equipment, and they inform you about the different classes available, from yoga to TRX. This onboarding experience ensures that you feel welcomed, informed, and ready to kickstart your fitness journey with confidence!

Similar to this experience, mobile apps also guide you through their features and functionalities, using onboarding screens. Let’s explore this in detail.

## What is Onboarding?

Onboarding is the process of getting users familiar with a new interface. It's like the first chapter of a book, setting the stage for what's to come. Onboarding screens can include tutorials, interactive elements, and brief explanations to help users get started smoothly. Essentially, it's about making the initial user experience as seamless and informative as possible.

Contrary to popular belief, it's not just about familiarizing users with interface interactions but also includes the essential task of completing any setup requirements. Moreover, onboarding extends its reach beyond the initial voyage of first-time users; it extends its welcoming embrace to existing users when new features or redesigns make their debut. 

## When to Use Onboarding Pages

**Complexity**: If your app has complicated features or workflows that might not be immediately obvious to users, onboarding can help guide them through.

*Example: A project management app might use onboarding to explain how to create projects, assign tasks, and track progress.*

**New Features**: Whenever you introduce significant updates or new features, onboarding can inform existing users about these changes and how to leverage them effectively.

*Example: Social media platforms often use onboarding to introduce new features like stories, reels, or live streaming.*

**Value Proposition**: Onboarding is an excellent opportunity to showcase the unique value proposition of your app and hook users right from the start.

*Example: A meditation app might use onboarding to highlight its guided meditation sessions, personalized recommendations, and progress-tracking features.*

**User Engagement:** If you want users to explore various features of your app and understand its full potential, onboarding can encourage them to do so.

*Example: A fitness app might use onboarding to encourage users to set up their fitness goals, track workouts, and explore meal plans.*

## When and Why -NOT- to use Onboarding pages

While onboarding may seem like a necessary component for every app, it's essential to critically evaluate its benefits against its potential drawbacks. In many cases, users can learn to navigate an app organically through exploration and context-based guidance, making lengthy onboarding processes unnecessary.

Here are some reasons on why not to use them:

**Higher Interaction Cost**: Implementing onboarding flows adds an additional step for users, increasing the interaction cost of using your application. Even if users choose to skip onboarding, they still must take action to do so, potentially hindering the smooth flow of their experience within the app.

> **Interaction Cost**: The interaction cost is the sum of efforts — mental and physical — that the users must deploy in interacting with a site to reach their goals.

**Memory Strain**: Onboarding often relies on users remembering specific details about the interface, such as icon meanings or navigation steps. However, human memory is limited, and asking users to remember too much can strain their cognitive load.

**Experts' Recommendation**: Given the drawbacks and potential inefficacy of onboarding, professionals are advised to avoid creating onboarding flows whenever possible. Instead, prioritize efforts to enhance the usability of the app's interface, making it more intuitive and user-friendly for both new and existing users.

## Examples of Onboarding Cases

The following examples represent a few, simple onboarding experiences that aim to introduce users to the app's features and functionalities in a clear and user-friendly manner.

>*According to NNGroup*

### The Psychology Behind Microinteractions

At their core, **microinteractions use psychological principles** to enhance the user experience. For example, the principle of operant conditioning suggests that users are more likely to repeat behaviors that are rewarded or reinforced. Microinteractions capitalize on this by providing immediate feedback or rewards for user actions, such as a satisfying animation or sound when a task is completed.

Microinteractions also draw on  principles of cognitive psychology, such as the concept of mental models. By designing interactions that align with users' mental models of how a system should behave, designers can create a sense of predictability and consistency that fosters user confidence and engagement.

Additionally, microinteractions often incorporate elements of emotional design, aiming to evoke positive emotions and create a sense of delight or satisfaction in users. This can be achieved through playful animations, charming illustrations, or personalized interactions that cater to individual preferences.

By understanding these psychological principles and integrating them into the design process, designers can create microinteractions that not only meet users' functional needs but also resonate with them on a deeper, emotional level, ultimately enhancing the overall user experience.

### The Role of Microinteractions

Microinteractions serve several purposes in UX design:

- **Showcasing System Status**: They keep users informed about ongoing processes, providing clarity and control.

- **Encouraging Engagement**: By offering quick feedback, they encourage users to interact more deeply with a product.

- **Facilitating Seamless Interaction**: They guide users through interfaces, making navigation intuitive and error-free.

Grids: Design's Silent Organizers

In the realm of Human-Computer Interaction (HCI) and User Experience (UX) design, mental models stand as crucial constructs shaping how users perceive and interact with digital interfaces. A mental model represents the user's perception and understanding of how a system or product functions. Let's take a closer look at this concept and its importance in UX design.

### What Are Mental Models?

At its core, a mental model encapsulates what users believe about a system, be it a website, an application, or any other product. These models help users predict the behavior of a system, influencing their interactions with its interface. It's important to note that mental models are not necessarily based on factual knowledge but rather on users' perceptions and past experiences.

### The Role of Mental Models in UX Design

Mental models play a pivotal role in UX design as they guide users' actions within an interface. Designers strive to ensure that the interface effectively communicates the nature of the system, enabling users to form accurate mental models. However, a common challenge is the mismatch between designers' and users' mental models, which often leads to usability problems.

Example:

Let's say the designer envisions a checkout process with a clear step-by-step checkout flow:

- select items
- input shipping details
- choose payment method
- review order, and
- confirm purchase

However, some users may hesitate to proceed past the shipping information page. This is because users expect a prominent "Continue" or "Next" button, whereas the design in this example may offer a subtle "Proceed to Payment" link.

This variance highlights how users' mental models, influenced by prior experiences, can differ from the designer's vision. Adjusting the interface to match user expectations, such as incorporating a more visible button, can enhance usability and streamline the checkout experience.

### Examples of Mental Models

**1. Norman Doors**

One classic example of mental models in UX design is the concept of "Norman Doors," popularized by Don Norman, a renowned UX designer. Norman Doors refer to doors with ambiguous or inconsistent affordances, where users struggle to determine whether to push or pull. Translating this to digital interfaces, users may encounter buttons or icons that don't clearly indicate their intended action, causing confusion and frustration.

<figcaption>Image reference from the book “The Pocket Universal Principles of Design” by William Liddell, Kritina Holden, and Jill Butler.</figcaption>
</figure>

**2. Familiarity with Iconography**

Another example lies in users' familiarity with iconography. Icons serve as visual cues within interfaces, conveying functionality or actions. For example, the "hamburger menu" icon, consisting of three horizontal lines, is widely recognized as a symbol for accessing a menu or navigation drawer. By leveraging users' mental models of familiar icons, designers can enhance usability and streamline user interactions. Below is an illustration showcasing the hamburger menu icon in a mobile application:

set of assets, designers can work together more seamlessly, reducing duplication of effort and minimizing 
inconsistencies.

### Examples of Design Systems in Action

Implementing a design system involves more than just creating a library of components—it requires thoughtful 
consideration of how those components will be used. For example, companies like Google and Airbnb have developed 
extensive design systems that not only define visual elements but also provide guidelines for motion, accessibility,
and even voice interactions.

Similarly, anyone can benefit from design systems by creating modular design libraries that can be easily 
customized and adapted for different projects. Tools such as Sketch, Figma and Adobe XD offer robust features for 
creating and managing design systems, making it easier for teams of all sizes to adopt this approach.

### Design Systems vs. Style Guides

While design systems and style guides share similarities, they serve different purposes in the UI/UX design process.

Design systems take a more holistic approach. They encapsulate everything from typography and colors to layout 
grids and interactive elements, providing designers and developers with a centralized resource to reference and 
leverage.

In contrast, style guides typically focus on visual aesthetics, outlining rules for typography, color palettes and 
general brand consistency. However, they often lack the depth and flexibility needed to support complex user 
interfaces. Think about it more like a set within a larger set; a design system.

### Conclusion

In an increasingly digital world, the demand for seamless and intuitive user experiences has never been greater. 
Design systems offer a powerful solution to the challenges of maintaining consistency and efficiency in UI/UX 
design, providing teams with the tools they need to create cohesive and impactful products.

communication channel between a product and its users, providing valuable updates, feedback, and alerts.

Let's take a look at the differences between validations, notifications and indicators, as well as how they're used!

### Validations, Notifications and Indicators

Effective communication with users includes three main types: notifications, validations and indicators, each of 
which plays a different role in guiding interactions and improving the user experience.

#### Indicators

Discreetly signal system status and help users navigate interfaces effortlessly. Whether it's a subtle colour 
change or a small icon, indicators convey important information without overwhelming the user.

> For example, an indicator could be a circular icon next to a user's profile picture that changes colour to indicate 
online status; green for availability, yellow or orange for away, and grey or even disappearing for offline status.

#### Validations

Provide real-time feedback, ensuring that users enter information correctly and minimising errors. By providing 
immediate responses to user actions, validations increase user confidence and streamline interactions.

> For example, a validation could might occur when a user attempts to submit a form without filling out required 
fields. When the submit button is clicked, the system may display a validation message next to each empty required 
field, indicating that it must be filled in before the form can be submitted.

#### Notifications

Serve as a valuable communication channel, providing users with timely updates and alerts. From 
notifying users of new messages or updates to alerting them to important system changes, notifications keep users 
engaged and informed.

> For example, a notification could appear when a messaging app alerts a user about a new message received from a 
contact. When the message is received, the app may display a notification banner at the top of the screen, 
accompanied by a sound or vibration to get the user's attention.

### Conclusion

In conclusion, while validations, notifications, and indicators serve distinct purposes in user interface design, 
they collectively contribute to enhancing the overall user experience. A structured approach to notification design 
is essential to ensure consistency and effectiveness. By prioritising notifications based on importance and adhering 
to established frameworks, designers can create intuitive systems that fit seamlessly into users' workflows. 

Ultimately, thoughtful notification design not only increases user engagement, but also contributes to the overall 
usability and success of digital products and services.

The Art of Communication: A Dive into Notifications, Validations, and Indicators

A deep understanding of human psychology, and in particular how memory works, is essential to UI/UX design.  Memory 
has a significant impact on how users interact with digital interfaces, affecting their ability to navigate, 
comprehend, and retain information effectively. By understanding how people recognize and remember things, and how 
our brains deal with short-term information, designers can craft more intuitive and user-friendly interfaces.

### Recognition VS Recall

Recognition versus recall is a key concept in UI/UX design. Recognition involves the identification of information 
when it's presented on repeat, like recognizing a familiar icon or interface element. For example, answering the 
question "Is Athens the capital of Greece?" involves recognition, because the question involves more cues for the 
answer. This method requires less cognitive effort and naturally enhances user-friendly interfaces.

Recall, on the other hand,  requires information to be retrieved from memory without external cues, which is more 
challenging and increases the likelihood of error. For example, answering the question "What is the capital of 
Greece?" requires recall, because the question has less cues.

Designers can make the most of this understanding by including familiar patterns, icons, and navigation structures 
to facilitate recognition and make user interactions more efficient.

### Short-term memory

Short-term memory, enforces limitations on how users can process and retain information in digital interfaces. 
Understanding its capacity and duration is crucial: did you know that people are able to hold only around 7 chunks 
of information in their short-term memory at one time?

Optimizing content presentation by breaking down information into digestible chunks, employing clear visual 
hierarchies, and providing feedback to reinforce users' mental models can minimize cognitive overload and enhance 
usability. Additionally, strategic use of visual cues can guide users' attention and boost information retention.

### Conclusion

Considering insights from psychology, especially those related to human memory, into UI/UX design practices, can 
seriously boost how user-friendly and effective digital interfaces turn out to be. Prioritizing recognition over 
recall and implementing strategies that take into account the limitations of short-term memory, designers can 
create intuitive, user-centred experiences that resonate with their audiences. As technology advances, a deep 
understanding of human cognition remains a must in shaping the future of digital interaction design.

Psychology and UX: What’s with the human memory?

That’s fascinating how designs can tell their own exciting stories based on where they come from, as an example, 
let’s have a precise look at Chinese and European designs. Every click and swipe is a peek into centuries of culture,
innovation, and history. I see it as a trip across continents to explore how these regions use technology to 
express themselves in unique ways. Through real-life examples, we'll notice how tradition and future dreams blend 
into their digital designs.

### The Cultural Context

#### Chinese UI/UX: A Symphony of Complexity and Integration

Chinese digital platforms are renowned for their highly integrated and feature-rich interfaces. Apps like WeChat and 
Alipay are not merely messaging or payment apps; they are ecosystems that offer a multitude of services, from social 
media and e-commerce to public services and financial products. This complexity reflects the Chinese cultural 
preference for holistic solutions and community-oriented spaces.

Example: WeChat's interface allows users to book taxis, order food, make payments, and even schedule doctor's 
appointments, all within a single app. This "super app" concept is a direct reflection of the Chinese market's 
preference for multifunctionality and convenience.

#### European UI/UX: Clarity and Minimalism

In contrast, European UI/UX design often emphasizes clarity, simplicity, and minimalism, reflecting a cultural 
inclination towards individuality and directness. European apps tend to focus on doing one thing well, providing a 
clean and intuitive user experience that makes it easy for users to accomplish their goals without unnecessary 
distractions.

Example: Spotify, a European-born app, showcases this approach with its clean interface, straightforward navigation, 
and focus on personalizing the music listening experience for each user, emphasizing the individual's choice and a 
clutter-free environment.

### Historical Influences

#### The Legacy of Writing Systems

The complexity of the Chinese language, with its 50,000 characters and the importance of calligraphy, has influenced 
the design of Chinese digital interfaces. The need to accommodate complex characters and make them legible has led 
to a more flexible approach to layout and information density.

Chinese websites and apps often feature a higher information density compared to their Western counterparts, partly 
to accommodate the intricacy of the script.

#### The European Design Tradition

Europe's rich history in art, design, and typography has deeply influenced its UI/UX design principles. The European 
design ethos, with its roots in movements such as Bauhaus and Swiss Design, emphasizes cleanliness, readability, and 
the efficient use of space.

The use of whitespace, a hallmark of European design, not only enhances readability but also aligns with the 
European aesthetic of simplicity and elegance.

### Technological Trajectories

The technological adoption paths of China and Europe have also played a significant role in shaping UI/UX designs. 
China's leapfrogging over traditional PCs to mobile internet usage has influenced the development of mobile-first 
and mobile-only applications. In contrast, Europe's gradual transition from desktop to mobile internet usage has 
resulted in a more conservative approach to mobile UI/UX design, with a stronger emphasis on adapting existing 
desktop designs to mobile platforms.

### Conclusion

The differences between Chinese and European UI/UX designs are a reflection of each culture's values, history, and 
technological evolution. From the holistic, feature-rich ecosystems in China to the minimalist, function-focused 
designs in Europe, these digital interfaces tell a story of diversity and innovation. Understanding these 
differences not only enriches our appreciation of global digital cultures but also highlights the importance of 
cultural context in designing user experiences that resonate with local users. As the digital world continues to 
evolve, the interplay between culture, history, and technology will undoubtedly continue to shape the future of 
UI/UX design.

The Great Digital Wall: Bridging the UI/UX Gap

Drawing from our experience in the tech industry, we've identified some common pitfalls and bottlenecks our teams
had to face throughout the years.

Naming just the problems isn't that valuable so for each issue we will share some techniques and practices that are 
battle-tested and have helped us to deliver some quite challenging projects. Let's dive in!

1. **Scope Creep Creeps Creepily**
    - **What it's about:** Just when you've nailed down what the project is about, a key stakeholder wants to add "just 
      one more thing". Sometimes it might be a small feature, other times it might be a whole new product though.
    - **Solution:** Successful projects start with successful Statements of Work. Detailed Statements of Work 
      that include "in" and "out-of-scope" sections can help you build a very strong and sincere relationship with your 
      customers, manage their expectations and protect them from getting carried away from their passion and 
      excitement. Arrange frequent catch-ups on a weekly basis with stakeholders to keep the project aligned and 
      feasible.

2. **The Never-Ending Planning Party**
    - **What it's about:** Endless planning sessions can lead to a cycle of meetings that plan more meetings and 
      producing useless artifacts that are never used. We've seen projects that spent months in planning, without 
      much progress or that they confused planning with execution and forget that someone should make the connection 
      between the two worlds, business and development.
    - **Solution:** Set clear, actionable milestones and deadlines to transition efficiently from planning to 
      execution. Above all, we are here to prepare for the development phase and ensure its success. This is why we 
      always start with a **Discovery Phase** to prepare meaningful documents and artifacts with user stories, 
      flowcharts, and clickable prototypes to put business ideas into a frame and spot deadends early enough.

3. **Budget, What Budget?**
    - **What it's about:** Budgets often underestimate the actual deliverables costs, leading to overspending and 
      financial strain.
    - **Solution:** Thorough upfront budgeting and splitting the whole project into phases and paid milestones. 
      This helps us build trust with the customer and stay on top of the financial control throughout the whole 
      project. **Discovery** and **Design** phases are the best way to get a clear picture of the project's scope and 
      budget and then plan accordingly. This is why we should never start a project without running a proper 
      **Discovery Phase** first.

4. **Deadline? More Like a Guideline**
    - **What it's about:** Deadlines often shift due to various unforeseen challenges, delaying project completion.
    - **Solution:** Realistic timelines and agile management techniques help us stay on track and adapt to changes. 
      Be careful, Agile can bite you seriously if you do it wrong though. Working against target dates and frequent
      checkpoints is the best remedy here as long as these dates make sense for both business and development teams. 
      Above all, we are here to deliver value to the business so both sides have to be aligned.

5. **Technology Tantrums**
    - **What it's about:** New technologies and experimentations can be unpredictable, causing delays and technical 
      issues.
    - **Solution:** We minimize tech-related disruptions by using proven technologies and well-known tools such 
      as Figma, ReactJS, TailwindCSS, Python Django, Docker, AWS cloud services etc. There is no room for 
      experiments when there are clear goals to accomplish.

6. **The Talent Tango**
    - **What it's about:** Retaining skilled team members or even onboarding new ones can be a major hurdle in project 
      completion.
    - **Solution:** Focus on hiring skilled, adaptable professionals and fostering a collaborative work 
      environment where transparency is king. Well defined handbooks with best practices and clear **Definition of 
      Done** principles can help hugely too. Above all, firms should help new team members accelerate and become 
      useful members of the team fast while adapting to predefined tools and techniques. Randomness is the perfect 
      recipe for chaos so this has to be eliminated by establishing a common language to communicate. 

7. **Communication Breakdown, It's Always the Same**
    - **What it's about:** Poor communication between teams can lead to misunderstandings and errors. Business 
      stakeholders and developers often speak different languages.
    - **Solution:** Emphasize clear, consistent communication channels, regular team meetings, and above all 
      high transparency levels. Again, we can't stress enough how important it is to run a **Discovery Phase** before 
      jumping into Development. This is the phase where we can align the business and development teams and we 
      prepare the ground for a successful project. Weekly catchups also are vital to keep the project aligned and 
      build trust with your customers.

8. **UATs Feature Frenzy**
    - **What it's about:** Stakeholders often demand additional features, complicating and overloading the project 
      during UATs since this is the very first time they deal seriously with the new platform. This is too late and 
      too dangerous.
    - **Solution:** Focus on the SoW deliverables, manage stakeholder expectations through clear communication and 
      involve them in demonstrations and feedback sessions from the very first milestone. Every week a demo takes place where we 
      present the progress of the project and we get feedback from the stakeholders. Such a feedback is priceless 
      and helps teams to stay on track and deliver value to the business. Don't forget that you need to manage 
      expectations and protect customers from their own excitement and anxiety which are quite high during 
      UAT periods so sometimes open and honest discussions might help them realize that they are pushing the project 
      over the cliff with their approach. It is your duty to remind this to them.

### Conclusion

So what is the key for a successful project? The key is embracing the powerful partnership with our customers. 
Casting blame or treating them as the enemy is a fundamental misstep. Instead, our greatest successes are born from 
collaborative efforts, where we stand shoulder-to-shoulder with them, navigating challenges together.

Our mission is clear: to assist ambitious customers in achieving their goals, transforming their vision into reality,
and boosting their business. This synergy, where consultation meets client aspiration, is where true innovation and 
progress are sparked. Together, we're not just solving problems; we're setting new benchmarks in the tech world.
