Put the user experience first

What is the difference between UX and UI?

UX design and UI design are both crucial for a product's success. However, they are distinct disciplines with different goals. While UX focuses on the overall experience, UI focuses on the graphical interface.
User-centered Ux design

Ux (User Experience)

This refers to the overall experience of using a product, the layout and design of the structure, its organisation, layout and the interactions between the different elements.

In other words: what users will find and how they will find it. The aim is to ensure that the "persona users" identified can achieve their objectives as simply and intuitively as possible.

The Ui (User Interface)

This is the graphical interface through which users interact: website, application, CRM or SaaS. It includes all the visual elements such as the colour palette, typography, images, illustrations, icons, etc.

The aim of Ui design is to make interfaces visually appealing, creating a "wow" effect and user-friendliness in the product.

How do you create an effective brief for your UX UI agency?

If you're a start-up or a company that has reached a growth stage that's prompting you to rethink your ux ui design or product design strategy, we've put together a selection of the ideal behaviour to adopt if you want your support to be a success.

When you're ready to start working with a Ux UI agency, the first step is to create an effective brief. The aim of the brief is to help the agency understand your needs so that it can offer you the best possible solution.

To do this, it needs to be as clear and concise as possible. Avoid providing too many details about what you want, as this will only confuse the agency.

Here are some tips on what to include in your brief:

  1. A clear description of your project and its objectives. What are you trying to achieve with this project (ui performance, conversion rate, sales, engagement, etc.)? ✅

  2. An overview of your target audience and their needs. Who is your project aimed at?

  3. The key features you want to include in your product. ✅

  4. Any specific design expectations or requirements you may have ✅

  5. Your budget and timetable for the project. How much do you want to spend and when do you need to complete the project? ✅

If you've been able to put together all or most of these elements and you need a ux ui agency, don't hesitate to send it to us for a quote and personalised advice on how to make your project a success. your project here.

The Collaboration Process with UX Agencies

Ux Audit

For a company to truly understand how its customers interact with its website or mobile app, it needs an overall view. The UX audit from What’zhat provides exactly that: a comprehensive view of what works well and what needs improvement from the user's perspective.

This approach consists of a detailed analysis of key pages or models on each device, to identify weak points in terms of user experience, ergonomics, wording, user-friendliness or clarity of message - nothing is left to chance. It starts with tailor-made research to understand the design system of your web development, the relevance and interaction of the interfaces between them, the strategy and performance of your website: conversion rate, retention, satisfaction and measures for improvement. This service is tailor-made to suit your customers: the expectations and approach are different if you are based in Paris or Hong Kong, or if you sell services or products via an e-business.

Thanks to this valuable feedback, you'll have an idea of how to optimise your website, top recommendations and other key data to ensure that your customers have a positive and successful experience with your company.

The days of guessing what your customers want are over!

Persona Research

To design an experience that your customers will love, you need to know who they are. That's exactly what What'zhat's persona study does.

A persona is a fictional character that represents a specific type of user. Creating a UX persona or user persona is an essential part of the design process because it helps us understand the deep needs, expectations, and goals of your users. This way, you'll know exactly what they want, and you can deliver it to them.

At What’zhat, we create personas based on user tests and real data from your target audience. This allows us to design user flows (the digital journey) and identify the screens and interfaces that will meet their specific needs.

We ensure that every design element aligns with the same goal: providing your users with a smooth and exceptional experience.

As a result, you will see an increase in customer satisfaction, loyalty, and conversions.

Ux Conception

User experience (UX design) is based on the identified personas and created user flows. We will design the sitemap, which are graphical representations of the user journey, by creating the pages, interactions, and hierarchy of your future website or mobile application.

A sitemap, or site plan, is a very useful tool for the entire project, as it allows all project stakeholders (project manager, product manager, designers, and developers) to have an overview of the platform and start planning the layout accordingly. It can also be used to indicate the priority of pages relative to one another, help with content organization, identify the user journey, and pinpoint missing screens (design dead-ends).

We ensure that all important information is easy to find and that users can get where they need to go with a minimum number of clicks.

Always centred on our typical persona, we then design the screens by "wireframing", responding to their needs at every stage of the process.

Our team of designers will create high-fidelity digital mock-ups, in line with your brand image and communications, that will take your users on a journey they won't forget. We pay particular attention to detail, because even the smallest element can have a big impact on the overall experience.

Our ultimate goal is to create ergonomic, intuitive, addictive, and enjoyable digital experiences for your users, continuously impressing them and encouraging them to return.

Our UX design teams consist of expert designers who are passionate about their work. We always stay at the forefront, ensuring that your product uses the latest trends and best design techniques to support your marketing efforts.

Ui Conception

The user interface (Ui design) is the graphic and visual part of your digital product. We apply your company's brand image and style to our mock-ups, which we also call "mockups". A mockup is a static representation of a screen. It contains all the elements that will be present on the screen, such as text, images, photos, graphics, etc.

A successful web template must be intuitive: users must understand how to use it without any instructions and find what they are looking for easily by following the defined path. The elements on the screen must be arranged in an orderly fashion according to the theories of graphic design, so that the text is legible, the images eye-catching and draw the eye to the desired elements. We spend an average of 82 seconds On a B2B website, usability is one of the keys to success for start-ups.

The interface must also be visually appealing so that users enjoy using it. Everything our agency does is based on analysis and research, from typography to color palette, marketing content, iconography, and micro-interactions, to create stunning user interfaces that will make your users fall in love with your product.

During this process, we will also design all custom illustrations.

Our agency generally uses Adobe XD and Figma, which allows us to have your projects and models online in the cloud, available 24 hours a day. It's at this stage that the project comes to life, getting ever closer to the final rendering.

We also work closely with your team of developers to ensure that our digital web designs and mock-ups are feasible and can be implemented without any problems. We also provide detailed documentation to ensure that the digital assets meet all the requirements, so that the web agency can easily take over the development and reproduce it faithfully (and that they don't take any design initiative 🙂 ).
