Designing interactions that take into account business goals and user needs brings numerous benefits:

  • Improved user experience - thoughtful product design translates into the intuitiveness, usability, and attractiveness of the interface, making it easier for users to identify with it and use it more willingly.
  • Closer achievement of business goals - systematic project documentation enables the creation of solutions that strictly fulfill business assumptions.
  • Increased competitiveness - aesthetic and functional design can differentiate a product in the market, attracting customers' attention and competing with other solutions.
  • Better brand identification - the consistency and visual uniqueness of the product strengthen the brand identity, building trust and recognition in the market.
  • Improved conversion - well-designed interfaces facilitate process execution, which translates into key performance indicators (KPIs) of the product, increasing efficiency and affecting financial results.
  • Improved SEO positioning - search engine algorithms favor websites with well-designed UX, which translates into lower SEO costs and paid campaigns.
  • Aesthetics sells - research confirms that customers are more likely to buy more through aesthetically pleasing and structured user interfaces.
  • Cost reduction - thoughtful and well-designed solutions can help avoid costly mistakes by focusing on optimizing the user interaction process.
  • Innovation - product design can also help generate innovative solutions and ideas to create more attractive and advanced products.

In general, albeit without reduction, design makes sense. Directly - by enhancing user comfort, and long-term - by increasing customer loyalty and return.

UX/UI Design — business benefits in numbers
  • A well-designed user interface translates into increased user satisfaction, which enhances business metrics (conversion rate, shopping cart size, return rate) and reduces costs associated with product design and development (optimization of usability during the prototype stage).

Design process

The basis of our work is the methodology known as the “double diamond” - a design process developed since the 1990s and widely used by designers.

The process involves an iterative and multi-stage approach to design, focusing on understanding the problem and user needs, as well as clarifying business objectives.

Here is the general course of this process.

The first diamond consists of two phases:

  • Discover - in this phase, designers focus on understanding the problem or challenge, identifying project goals, and user expectations. Methods we use include market research, competitive analysis, user needs analysis, creation of user personas, and customer journey mapping.
  • Define - this phase defines specific goals of the project and determines the areas that will be designed.

The second diamond contains the following two phases:

  • Develop - based on the insights and guidelines from the previous two phases, designers proceed to create product prototypes, which are then validated against the design assumptions and during user testing.
  • Delivery - in this phase, designers deliver final solutions for implementation along with design documentation and a design system to streamline the production process.

During the UX/UI design process, designers go through both diamonds, focusing on understanding the problem and creating solutions in the first diamond, and then delivering solutions in the second diamond. This approach allows for continuous iterations, refining solutions and incorporating user feedback at every stage, leading to better end results in the form of products tailored to user needs.

Listen to your customers
Maintain consistency between the system and reality
Give the user full control
Adhere to standards and maintain consistency
Prevent errors
Allow choices instead of forcing to remember
Ensure flexibility and efficiency
Take care of aesthetics and moderation
Provide effective error handling
Ensure support and documentation

(usability checklist)

In the course of the usability audit of pages, in addition to usability heuristics, we also use checklists. One of them is our publication Best Practices for E-commerce containing more than 200 recommendations for the design of online stores.

What will be the benefits and results of the UX/UI project?

The benefits and results of the UX/UI project will be improved user experience, leading to increased loyalty, higher conversion rates, and better user understanding and satisfaction, which will contribute to the success of the product in the market.

How long will the design process take?

The duration of the UX/UI design process can vary significantly depending on the complexity of the project, the scope of work, and available resources. A typical UX/UI project can take from a few weeks to several months. For a more accurate assessment of the project duration, it is important to conduct a detailed requirements analysis and identify project milestones.

What is the cost of the project?

The cost of a UX/UI project depends on a number of factors, such as the size of the project, complexity, scope of work and experience level of the specialists. A UX/UI project can have different costs, depending on the specifics of the project.
The cost of a UX/UI project may include salaries for UX/UI designers, the cost of user research, design tools, software, as well as possible costs related to testing and implementation.
To obtain an accurate cost estimate of the UX/UI project, it is necessary to provide a detailed project brief and agree on the scope of work.

What resources will be involved?

Resource engagement in a UX/UI project depends on its scale and complexity. They may include:
UX/UI Designers: This is a key group responsible for user interface design, user research, and creating solutions in line with best UX/UI practices.
UX Researchers: Professionals who conduct user research, analyze data and report results to help understand user needs and behaviors.
Project Manager: The person responsible for project management, team coordination, and client communication.
Content Specialists: For projects that require content development, these professionals can be engaged to create and optimize content.
Testers/Respondents: Individuals responsible for conducting usability tests and verifying whether the designed solutions meet user expectations.
Customer or Stakeholders: Active involvement of the client or stakeholders is crucial for defining project goals, providing feedback, and obtaining project approval.
Tools and software: UX/UI projects use a variety of tools and software, such as graphic design software, prototyping tools, data analysis software, and more.
Financial resources: Depending on the project scale, financial resources may be needed for salaries, tools, user research, and other project costs.

The resources involved in a UX/UI project may vary depending on the project and client needs. It is important to properly align resources with the scope of work and project goals.

Will there be prototypes or design samples available for verification?

In the course of the design work, the results of the work are provided to the client on an ongoing basis, depending on the contracted scope. These may include: reports and analysis results, workshop summaries, graphic designs with a visual concept (so-called look'n'feel), functional views (mockups), and final graphic views.
In addition, in the case of complex product design, the customer receives a Design System document which is a compilation of all key graphic elements of the website, such as: font styles along with their proportions and dependencies (headings H1, H2, etc.), primary and complementary colors, action colors, buttons, inputs, text fields, tables, grid, styles and other relevant graphic elements necessary for the project.
Ultimately, it can also be utilized during ongoing collaboration with third parties in the system development. This will significantly improve the quality and consistency of the implementation.

How will the success of the UX/UI project be monitored and measured after implementation?

Monitoring and measuring the success of the UX/UI project after implementation is a key step to assess the effectiveness and impact of the project on users and business objectives.

Here are a few steps that can be taken to monitor and measure the effects of the UX/UI project:

Define goals and success metrics - at the beginning of the project, you define the goals you want to achieve, such as increasing conversions, reducing customer service costs, or improving user ratings. Then, specific metrics are developed to evaluate these goals.
Examples of KPIs that can be used to analyze product effectiveness: Conversion Rate (CVR), Total Addressable Market (TAM), Year over Year (YoY) growth, Monthly Recurring Revenue (MRR), Annual Recurring Revenue (ARR), Annual Contract Value (ACV), Total Contract Value (TCV), Gross margin, Revenue churn, Customer churn, LTV/CLTV, Customer Acquisition Cost (CAC), Daily Active Users (DAU), Weekly Active Users (WAU), Monthly Active Users (MAU), Gross Merchandise Volume (GMV), Retention Rate, Net Promoter Score (NPS).

User tracking - parametrize analytical tools, such as Google Analytics, to track user behavior on the website or in the application. Analyze data on traffic, interactions, time spent on the website, and other indicators.

Conduct research and testing - the analysis is supplemented with user research to assess whether the changes made have improved the user experience. Usability tests, studies that involve observing user behavior and gathering user feedback, can be used.

Collect user feedback - ensure easy access to feedback forms, surveys, or customer service features enabling users to share their opinions and comments on the product.

Compare data before and after deployment - evaluate pre- and post-implementation data from the UX/UI project to assess the effectiveness of the changes.

Reporting and analysis - regularly prepare reports and analyze data to assess project progress and identify areas for further improvement.

Cyclical improvement - based on the collected data and conclusions, continuously improve the project through further iterations and enhancements.

User consultation - engage with users to learn their opinions about the product and understand what changes are important to them.

Monitoring and measuring the success of the UX/UI project after implementation allows for ongoing adaptation and improvements of the product, which is crucial to ensuring continued success and user satisfaction.
