User Experience Design for the best omnichannel services

We are your tech partner

Product-Market Fit

User Experience Design is the constant quest for finding the proper product-market fit. This is not created in front of a desk but crafted during research and interviews with users. A product without proper validation is just a waste of money and effort. Our Design Thinking Workshop is based on Google Sprints by Jake Knapp, LeanStartup by Eric Ries, and 24 Steps to Entrepreneurship by Bill Aulet, Dean at MIT.

What is a part of UX/UI Design?

Problem statement analysis

Always start with a problem. We need to understand the problem and who is experiencing it the most. Market research should provide the answers to why the existing solutions are failing and how much the users are willing to pay for a better way to solve the problem.

User interviews

Once the problem is defined, we need to conduct a series of interviews to confirm the problem statement and gain insights, which will be useful in the solution engineering phase. What matters is selecting the interviewees to match the possible target group.

Customer Journey and User Story Mapping

The first phase of the prototyping is all about understanding and documenting the processes. It is also important to prioritize between the features so that the final shape of the MVP is created. 

Low-Fidelity Mockups

Sketches and Mockups help visualize the initial idea and confirm the understanding between all stakeholders. They can also help validate some important assumptions with the target audience. 

Clickable prototype

The purpose of building the prototype is to simulate the look and feel of the real application without spending too much on development. This approach allows us to master the design and prepare the prototype for the focus groups with users and decision-makers. This is typically full of animations and transition effects to provide a fully immersive experience.

Design System

Whereas small startups need to be agile and deliver super-quick MVPs, often sacrificing the long-term quality of the product, in regular enterprise projects, we always start with the Design System. It helps maintain coherence, streamlines communication between designers and developers and shortens the time to market by reusing the components. The true strength of the Design System is shown when additional interfaces are needed.
