UI/UX Design Process and Deliverables: Client Guide

Don't neglect UI/UX design, or you will most probably have greater development costs. Make it your competitive advantage.
According to a McKinsey report, companies that focus on UI/UX design can see revenue growth of 32% more than their competitors and 56% higher payments to stakeholders.
As practice shows, neglecting UI/UX design can and does often cause extra software project development costs.

This article will guide you through the design aspects at different stages of your project implementation. It also discusses deliverables you can expect from Solvd professional teams at the end of a certain phase, explains how a wise approach can help you save budget, and how to equip your product or solution with a significant competitive advantage.

When to Go For UI/UX Design and What Development Teams to Engage

Each project is unique and encompasses particular stages. However, there are four basic cases you may commonly bump into when starting or running your software project:

  • You have a rough idea.
  • Your idea is documented properly, and you are planning the next steps.
  • Product mock-ups or a working solution are ready.
  • Your existing product needs a competitive edge via adding great usability with an excellent look and feel.
Design project stages
On your way to implementing your software project, you will need different professional teams to assist. There are several roles in UI/UX design process, and teams have different goals:

  • Business Analytics. It is vital to have business requirements translated into a language understandable to the development team and provide sufficient details.
  • UX Designers. These specialists match user needs and experience with business goals and care about whether a customer uses the product after purchase, how, and why.
  • UI Designers. They transform all requirements into a convenient, visually aesthetic, and attractive solution.
  • UX and Marketing Specialists. They are fighting in the global arena for customer retention, new sales channels, and prospects

Now that you know the teams to assist you and the basic cases when it is time to tap into the capabilities of design professionals, let's take a closer look at how Solvd can handle each of the cases for you and the deliverables you will receive.

You Have a Rough Idea; We Propose Discovery Phase

So, you have a million-dollar idea and have already researched the market. How to execute your rough idea?

You need professional business analysts and usability experts to help you identify the target audiences and their needs and map out your concept. You can expect the professionals to deliver the following reports:

  • Job Stories and acceptance criteria
  • User personas
  • Non-functional requirements
  • Flow diagram
  • Low fidelity wireframes
  • Architect review
  • Project estimation

Each report has its role in the project and is important for the overall result. Let's analyze each one in detail.

Job Stories and Acceptance Criteria

Job Stories and Acceptance Criteria
When ___[user role + situation], I want to ____[motivation], so I can ___[expected outcome].
You may wonder why you need Job Stories and Acceptance criteria. Yes, you can dish out tasks to the engineers, but that would be as if you are developing blind. Tasking separately may exceed the project budget, cause confusion and add inconsistencies to the project.

Here is how Job Stories may facilitate and enhance the efficiency of your development efforts:

  1. Job Stories provide context and roles, which allows the team to delve into the project and user needs.
  2. They allow you to accurately plan the project, increase the predictability of the project, simplify monitoring processes for managers, as well as simplify the process of implementing changes.
  3. The Stories give developers a clear understanding of what they should complete at a particular development stage.
  4. Without Job Stories and Acceptance Criteria, you will have to waste lots of time communicating with QA and testing specialists and explaining to them all the nuances. Manual and automation testing is a critical part of software project development, and you can learn more about the importance of Quality Assurance and Quality Control in one of our recent articles.
  5. When you take advantage of Job Stories, you can get a detailed assessment of the project before the development starts.


Without a clear understanding of why creating personas is necessary, you may waste your budget. Let's clarify: UX personas allow focusing on real-world clientele with their needs and expectations. They should be created based on market/user research, not just the vision.

Personas aren't meant to inflate costs for a client. They are needed to provide a development team with valuable information. For instance, UI/UX designers will be more interested in learning about previous experiences target users have had using different applications. And the sales team will be more interested in users' age, job position, or purchasing motivation.

Creating user personas is extremely helpful in choosing your solution features, thinking out the development processes, and creating informed wireframes.

Non-Functional Requirements

Non-functional requirements
These requirements describe the way a system should function and involves at least the following components:

  • Performance
  • Accessibility
  • Adaptability
  • Audit
  • Architecture standards
  • Scalability
  • Maintainability
  • Business continuity
  • Integrations
  • Security
  • Key usability points

The report describes the basis of your solution design and helps plan and coordinate future design and development efforts of your provider's teams.

Flow Diagrams

Diagrams and Wireframes
Everyone who starts working on a project begins to draw User or Business Flow diagrams inside one's head. It's better to avoid minor inconsistencies from the very beginning and demonstrate the business model and how the user will interact with the project.

Low Fidelity Wireframes

Low Fidelity Wireframes
At this stage, different nuances may occur and should be discussed. If your project is small, professionals may create high fidelity wireframes, even ones similar to a final design. But if your project is large-scale, it's better to start with low-fidelity wireframes.

Architect Review

Architect Review
This report estimates a project scale and gives the developers a view of what they are doing to work with in detail. It determines whether the existing artifacts are enough to start the development and what their quality is.

Architect reviews help teams to ensure from the beginning that the final solution will be secure and modifiable the way it should be. It also describes how many unforeseen expenses you as a client may expect and how your solution can be adjusted to save costs.

Project Estimation

Project Estimation
The basis for this report is the dialogue between a client and the provider. It describes the client's business goals and the type of software solution needed based on the information provided by the client.

Business analysts will then dissect the gathered information and create a feature list that will be assessed by each department, including software developers, UI/UX designers, marketers, QA, and testers. These professionals will advise about the number of hours the project requires and the development costs.

You Have a Properly Documented Idea; We Do Visual Prototyping

If you have a detailed documented idea, professional UI/UX designers and consultants can help you visualize it. Visual prototypes can be basic and show a solution's backbone and the interaction design that describes the more complicated layers.

Low Fidelity Prototyping

Low Fidelity Prototyping
To make clients' ideas tangible, UI/UX designers create low-fidelity wireframes or quick simple sketches. Such wireframes are usually black and white schemes that outline a project as a whole, leaving out the details. Design consultants will use simple boxes and lines to identify the UI design elements.

Low fidelity prototyping is easy and fast to draw up, but its look is basic. They allow teams to test user features and are best suited for the following:

  • Planning and designing the user interface
  • Idea documentation
  • Brainstorming and discussing ideas in a team
  • Collecting feedback from a target group

High Fidelity Prototyping

Low Fidelity Prototyping
This wireframe is a colorful and interactive representation of a future solution, which is most often used for the following:

  • Presenting an idea to investors and stakeholders
  • Performing user testing to see if the target audience welcomes the business idea. The idea may require modifications before the development starts.

You may easily confuse a high-fidelity prototype for a simplified final design. But that's not true since the prototype focuses on the business flow and data collection and requires considerable upgrades in terms of design.

You Have Mock-Ups or a Working Product; We Offer Research & User Testing

UI/UX design mock-ups
Statista reports that 60% of consumers rate usability as an important design characteristic for an online shop.
Users often wish to be polite and hide their lack of knowledge in a particular field. But that is not enough just to ask users a couple of questions. If they are not asked the right questions, they may give incomplete information in response. Follow-up tests are also needed to know if the chosen paradigm is correct.

There are many ways to receive feedback from your target audience, including simple questionnaires on social networks and inside the product or solution, personal interviews, field research, and more. The best method is the one that yields the desired results while minimizing costs. Feel free to learn more about how to hire UX consulting specialists.

You Need a Competitive Product With Great Usability, Excellent Look and Feel; We Do User Interface Design

MarTech Series says that half of the consumers consider a company's website design crucial to their opinion of that brand.
UI/UX digital designers prefer following the latest public or in-house research rather than creating something similar to what Apple, Facebook, or Google does. Mere copies of popular existing products don't guarantee your success. Instead, professionals focus on potential users, create experience maps, and choose a relevant visual language.

To create an appealing user interface design, Solvd teams delve into the following development aspects, the best methods, and tools:

  • Design Style KIT
  • Final Project Design
  • Transition Behavior
  • Animations
  • Handoff and Design Maintenance during project implementation

Design Style KIT

Design Style KIT
UI/UX design processes require consistency since chaotic efforts in design creation may lead to complications. Solvd designers deliver clear and well-structured deliverables that facilitate design and development.

The creation design system is closer to development rules than art. The deliverables should be easy to modify while spending as little time as possible on modifications.

Final Project Design

Your Final UI/UX Design
Solvd UI/UX designers appreciate experiments with new trends but keep in mind that what looks good on the surface isn't always user-friendly and efficient.

There are a few important points that designers should observe when working on making a custom software project successful:

  • Responsiveness and a smooth run of a solution on both mobile and desktop
  • Layouts for multiple screen sizes
  • The environment of a target audience
  • Convenience
  • Suitability for color blind and visually impaired users

Transition Behavior

Transition Behavior
Animated transitions are extremely important as they help users navigate through an app. Besides, apps that support gesture recognition become easy to interact with, and designers don't need to puzzle over how to allocate a lot of elements on a single page since gestures undertake some functionality.


Designing Animations
Every time it comes to designing wow effects or animations for an app, every client tries to find the right balance between effectiveness and costs. Keep the following in mind: what users feel may directly affect the conversion and retention rate. If neglecting the UI/X design process, you run the risk that your audience will rapidly thin out.

Solvd digital designers always try to find cheap and awesome solutions. Most often, there are several ways to make a particular animation simpler with less load on the development team. In some cases, designers pass the exported animation as a code file that can be inserted into a client's project.

Handoff and Design Maintenance

Handoff and Design Maintenance
At the stage of design implementation, Solvd specialists synchronize their effort with that of the development team responsible for a given project. In some cases, it's enough to transfer a structured file with different design states. Alternatively, a team may require annotations to supplement the files.

In the course of a project, a client may ask for instant and cheap changes that don't impact business logic and solution usability. Solvd designers always provide support at every development stage of a project, as well as provide assistance with project testing.


UI/UX design shouldn't be overlooked since it may help your business grow and achieve success by letting your clients feel that their interests are a priority and get right what they need. This guide to high-quality UI/UX design that meets the needs of a particular user group comprehensively describes what you need to do and what to expect from professional digital designers.

Creating an efficient UI/UX solution is never a job for designers in isolation. They will work closely with engineering, marketing, and sales teams and will keep the dialogue with clients on track, providing reports at every research and development project stage.
