UI/UX Design Brief Template for Websites, Apps, and Ecommerce

A UI/UX design brief documents the business problem, target users, product scope, required screens, functionality, constraints, deliverables, timeline, and handoff expectations before design work begins.

It gives stakeholders, designers, and developers a shared understanding of what needs to be created and why.

A clear brief does not need to contain every final answer. Its purpose is to provide enough context for the design team to understand the project, identify missing information, estimate the scope, and begin a productive discovery process.

This guide includes:

• A checklist of information to include
• Website, ecommerce, and app-specific requirements
• A copy-and-paste UI/UX design brief template
• A completed brief example
• Common mistakes to avoid
• Developer handoff considerations

A strong UI/UX design brief should explain the business problem, user needs, project goals, required pages or screens, important user flows, functionality, technical limitations, expected deliverables, stakeholders, budget, and timeline.

What Is a UI/UX Design Brief?

A UI/UX design brief is a planning document that explains the context and expectations of a website, ecommerce, SaaS, web application, or mobile-app design project.

It helps the design team understand:

• What is being designed
• Why the project is required
• Who will use the product
• What users need to accomplish
• Which pages, screens, and flows are required
• What functionality must be supported
• Which business or technical constraints exist
• What the design team is expected to deliver

The brief usually acts as the starting point for discovery rather than a fixed instruction document.

During the discovery process, designers may identify missing requirements, conflicting priorities, usability risks, or technical limitations that require clarification.

UI/UX Design Brief vs PRD vs Statement of Work

These documents support different parts of a digital project.

Document	Main purpose	Typical information
UI/UX design brief	Defines the design problem and project context	Users, goals, scope, screens, journeys, constraints, and deliverables
Product requirements document	Defines how the product or feature should work	Features, business rules, functionality, acceptance criteria, and technical requirements
Statement of work	Defines the commercial agreement	Responsibilities, fees, milestones, timelines, assumptions, and terms

A design brief may be used alongside a product requirements document and statement of work.

For a small website or landing-page project, the brief may be the main planning document. A complex SaaS or mobile-app project will usually require more detailed product and technical documentation.

Why a Clear UI/UX Design Brief Matters

A useful brief helps everyone involved in the project begin with the same expectations.

Reduces assumptions

Without clear context, designers may need to make assumptions about the users, functionality, priorities, or project boundaries.

A brief provides the information required to ask more relevant questions.

Improves project estimates

The number of screens, user flows, platforms, states, integrations, and deliverables affects the project timeline and cost.

Documenting these requirements helps the design team prepare a more realistic estimate.

Aligns stakeholders

Marketing, product, management, sales, and development teams may evaluate the project from different perspectives.

The brief creates a shared reference point for discussions and decisions.

Reduces avoidable revisions

Design revisions are a normal part of the process. However, changes caused by missing requirements or late stakeholder involvement can delay delivery.

A clear approval process and documented scope help reduce unnecessary revision cycles.

Supports practical implementation

Design decisions should account for the platform, existing technology, development resources, and technical limitations.

Providing this information early helps designers create interfaces that are more practical to implement.

What to Include in a UI/UX Design Brief

Most useful UI/UX briefs contain the following 12 sections.

1. Business Context and Problem to Solve

Begin by explaining what the business or product does and why the project is being started.

Include:

• Business or product overview
• Industry and market
• Main products or services
• Existing website or application
• Reason for beginning the project
• Current user or business problem
• Evidence that the problem exists

A weak problem statement might say:

Our website looks outdated.

A more useful version would be:

Mobile visitors find it difficult to compare our services and complete the enquiry form. Important information is spread across several pages, the navigation is inconsistent, and the form requires too many steps.

The second version gives the design team a clearer problem to investigate.

For an existing website, reviewing common website UX mistakes can also help you document the current issues more accurately.

2. Business Goals, User Goals, and Success Metrics

Define what the project should help the business and its users accomplish.

Business goals may include:

• Improve product discovery
• Generate more qualified enquiries
• Simplify customer onboarding
• Support a new feature or market
• Create consistency across the product
• Reduce avoidable support requests
• Prepare an MVP for development
• Improve an important customer journey

User goals may include:

• Find relevant information quickly
• Compare products or services
• Complete a purchase or booking
• Create and configure an account
• Understand a complex feature
• Complete a recurring task
• Review or export information

Also define how the outcome will be evaluated.

Possible success metrics include:

• Task-completion rate
• Form-completion rate
• Onboarding completion
• Product discovery
• Search usage
• Checkout progression
• Support-request volume
• Usability-test findings
• Customer feedback

Avoid guaranteed performance claims. The brief should document the current baseline and the method that will be used to evaluate the updated experience.

3. Target Users

Describe the people who will use the website, ecommerce store, application, or digital product.

Include:

• User type or role
• Industry or profession
• Geographic location
• Preferred devices
• Technical experience
• Main goals
• Common frustrations
• Accessibility needs
• Frequency of product use

A product may have several user groups.

For example, a marketplace may serve buyers, sellers, and administrators. A SaaS platform may include account owners, managers, team members, and support staff.

Each user group may require different permissions, journeys, information, and interface states.

4. Project Scope and Supported Platforms

Clearly state what is being designed.

The project may involve:

• Marketing website
• Ecommerce store
• Landing page
• Web application
• SaaS dashboard
• Mobile application
• Customer portal
• Marketplace
• Internal business software
• Design system

Also identify the platforms that must be supported:

• Desktop
• Tablet
• Mobile web
• iOS
• Android
• Responsive browsers

Document whether the project is:

• A new product
• A complete redesign
• A selected-page redesign
• A feature addition
• A UX audit
• A prototype
• A design-system update

Clearly stating what is outside the scope can be just as important as listing what is included.

5. Pages, Screens, States, and User Flows

Provide an initial list of the pages or screens that may be required.

Website examples

• Homepage
• About page
• Service pages
• Pricing
• Case studies
• Contact page
• Blog
• Landing pages

Ecommerce examples

• Homepage
• Category pages
• Search results
• Product pages
• Cart
• Checkout
• Customer account
• Order tracking
• Wishlist

SaaS and app examples

• Registration
• Login
• Onboarding
• Dashboard
• Profile
• Settings
• Notifications
• Reports
• Billing
• Team management

Do not include only ideal-state screens.

The project may also require:

• Loading states
• Empty states
• Error states
• Success messages
• Confirmation screens
• Form validation
• Permission states
• No-results screens

A page list explains what must be designed. User flows explain how people move through those pages.

Example ecommerce flow:

Product category
→ Apply filters
→ Open product page
→ Select a variant
→ Add to cart
→ Review cart
→ Complete checkout
→ View order confirmation

Document the most important user flows, their starting points, major decisions, and expected outcomes.

6. Functional Requirements

Explain what users need to be able to do.

Functional requirements may include:

• Search
• Filtering and sorting
• User accounts
• Role-based permissions
• Payments
• Booking
• File uploads
• Notifications
• Messaging
• Reporting
• Product comparison
• Saved items
• Location selection
• Social login
• Third-party integrations

Describe the expected behavior rather than naming only the interface element.

Instead of writing:

Add a calendar.

Write:

Users should be able to view available dates, select a time slot, provide their booking details, and receive a confirmation.

This gives the design team enough context to plan the complete interaction.

7. Existing Research and Data

Share any information that can help the design team understand the current user experience.

Relevant materials may include:

• Website analytics
• Conversion funnels
• Search Console data
• Heatmaps
• Session recordings
• Customer interviews
• Usability-test findings
• Support tickets
• Sales-team feedback
• Surveys
• App-store reviews
• Previous UX audits

Also clarify what is currently an assumption.

For example:

We believe users abandon the form because it is too long, but we have not yet tested this assumption.

This helps the team separate verified findings from internal opinions.

8. Brand, Visual Direction, and Content Inputs

Share all existing brand and content resources.

These may include:

• Brand guidelines
• Logo files
• Typography
• Color palette
• Photography direction
• Illustration style
• Existing marketing materials
• Component library
• Design system
• Product screenshots

Visual references can also be useful, but explain what you like about each example.

Instead of writing:

We like this website.

Write:

We like how this website organizes a complex service into clear sections and makes the primary action easy to identify on mobile.

UI/UX design examples should guide discussion rather than encourage direct copying.

Also clarify who will provide:

• Website copy
• Product descriptions
• Images
• Videos
• Testimonials
• Pricing
• Legal content
• Translations
• Help documentation
• Error and notification messages

Mention whether copywriting, content strategy, content migration, or multilingual layouts are required.

9. Technical, Accessibility, and Compliance Constraints

Design decisions may be affected by the existing technology and implementation environment.

Document:

• Content management system
• Ecommerce platform
• Front-end framework
• Existing theme
• APIs
• Third-party tools
• Payment systems
• Browser requirements
• Device requirements
• Current component library
• Development-team capabilities
• Known technical limitations

Also list relevant accessibility requirements, such as:

• Color contrast
• Keyboard navigation
• Form labels
• Visible focus states
• Error messages
• Screen-reader support
• Touch-target sizing
• Reduced-motion preferences

Include any industry, legal, security, or organizational requirements that the design team should consider.

These requirements should be confirmed with the appropriate legal, accessibility, security, or compliance specialists where necessary.

10. Expected UI/UX Deliverables

Clearly state what the design team is expected to provide.

Possible deliverables include:

• Discovery summary
• UX audit
• Competitor review
• User personas
• Customer journeys
• Information architecture
• User flows
• Wireframes
• Interactive prototype
• High-fidelity interface designs
• Responsive desktop and mobile layouts
• Design system
• Reusable components
• Accessibility annotations
• Developer specifications
• Exported assets
• Source design files

Not every project needs every deliverable.

A landing-page redesign may require wireframes, responsive UI designs, and developer notes. A large SaaS product may need detailed user flows, interface states, prototypes, and a reusable component system.

The deliverables should match the project’s complexity and implementation needs.

11. Stakeholders, Feedback, and Approval

Identify who will provide requirements, review the designs, and approve the final decisions.

Possible stakeholders include:

• Project owner
• Founder
• Product manager
• Marketing representative
• Sales representative
• Developer or technical lead
• Legal or compliance reviewer
• Final decision-maker

Also define:

• Who will collect feedback
• How feedback will be shared
• How often reviews will occur
• Who resolves conflicting requests
• Who provides final approval

Combining stakeholder feedback into one clear response can make the review process more efficient.

12. Timeline, Budget, and Dependencies

Document the important dates and dependencies.

Include:

• Expected start date
• Review milestones
• Target design-completion date
• Development-handoff date
• Planned launch date
• Content-delivery dates
• Technical-review dates
• Third-party approvals
• Campaign or business deadlines

Do not list only the final launch date. The project also requires time for discovery, planning, wireframes, reviews, interface design, revisions, and handoff.

Providing an approximate budget range can help the design team recommend a realistic scope.

The budget may influence:

• Research depth
• Number of screens
• Prototype complexity
• Responsive coverage
• Design-system requirements
• Testing requirements
• Revision stages
• Handoff documentation

Also identify dependencies that could delay the project, such as incomplete content, unavailable stakeholders, pending integrations, or unfinished product requirements.

Common UI/UX Design Brief Mistakes

1. Using Visual Preferences as the Main Objective

“Make it modern” or “make it look premium” does not explain the problem.

Describe what needs to become clearer, easier, or more useful.

2. Not Defining the Target Users

A design team cannot prioritize the experience without understanding who will use the product and what those users need to accomplish.

3. Listing Pages Without Explaining User Flows

A page list shows the size of the project. User flows explain how the experience should work.

Both are important.

4. Ignoring Empty, Error, and Loading States

Digital products must also support situations where an action fails, information is unavailable, a search returns no result, or a user has not completed setup.

5. Sharing Technical Limitations Too Late

Platform, theme, integration, and development limitations should be discussed before detailed designs are approved.

6. Leaving Deliverables Unclear

Confirm whether the project requires wireframes, prototypes, responsive layouts, source files, design-system components, accessibility notes, or developer documentation.

7. Involving Decision-Makers Only at Final Approval

Stakeholders who join late may introduce requirements that should have been discussed during discovery.

8. Setting a Deadline Without Review Time

The timeline should include stakeholder reviews, revisions, content delivery, technical feedback, and handoff.

9. Copying Competitors Without Understanding the Users

Competitor examples can provide context, but they should not replace research, product requirements, or user needs.

10. Treating the Brief as Unchangeable

A design brief provides initial direction. Discovery may uncover missing information or require an agreed change in scope.

What Happens After the Brief Is Approved?

A typical design process may include the following five stages.

1. Brief Review and Clarification

The design team reviews the users, goals, scope, functionality, timeline, constraints, and deliverables.

Missing or conflicting information is discussed with the stakeholders.

2. Scope and Research Planning

The team confirms the pages, screens, flows, milestones, research activities, and review process.

Existing analytics, customer feedback, and product information may also be reviewed.

3. User Flows and Wireframes

The information architecture, navigation, task flows, and page structures are planned before detailed visual styling begins.

4. Interface Design and Validation

Approved structures are developed into detailed interfaces.

Depending on the project, prototypes, stakeholder reviews, usability testing, or technical reviews may also be completed.

5. Developer Handoff

The final design files, components, assets, responsive behavior, interaction notes, and implementation requirements are prepared for the development team.

When to Involve a UI/UX Professional in the Briefing Process

A template can help organize your initial requirements, but some projects require professional support before the scope can be finalized.

Consider involving an experienced UI/UX professional when:

• Requirements are still unclear
• Stakeholders have conflicting priorities
• Important user journeys are complex
• The current product has usability problems
• A new website, SaaS platform, or mobile app is being planned
• The interface has become inconsistent
• The project must work with an existing technical system
• User research or usability testing is required
• Designs must be prepared for an external development team
• A reusable component system is needed

Experienced UI/UX experts can help clarify the project scope, organize user flows, create wireframes and prototypes, and prepare implementation-ready interface designs.

Frequently Asked Questions

What Is a UI/UX Design Brief?

A UI/UX design brief is a document that defines the business problem, users, goals, scope, required functionality, constraints, deliverables, stakeholders, timeline, and budget of a digital design project.

It provides the initial context required for discovery and planning.

Who Should Write a UI/UX Project Brief?

The brief may be prepared by a founder, product manager, business analyst, marketing manager, project owner, or internal product team.

A UI/UX professional can help clarify and structure the document when requirements are incomplete or several stakeholders are involved.

How Long Should a UI/UX Design Brief Be?

There is no required length.

A small landing-page project may need only a few pages, while a complex ecommerce, SaaS, or mobile-app project may require detailed information about users, roles, functionality, integrations, and interface states.

Clarity is more important than length.

Is a Design Brief the Same as a Product Requirements Document?

No. A design brief focuses on the users, design problem, project context, interface scope, and expected deliverables.

A product requirements document usually contains more detailed feature requirements, business rules, functionality, and acceptance criteria.

What UI/UX Deliverables Should Be Included?

Deliverables depend on the project and may include user flows, information architecture, wireframes, prototypes, responsive interface designs, reusable components, accessibility notes, and developer specifications.

They should be agreed upon before the detailed design stage begins.

Can a UI/UX Professional Help Define Unclear Requirements?

Yes. A UI/UX professional can review the business goals, current product, user needs, stakeholder expectations, analytics, and technical constraints before recommending an appropriate design scope.

Start Your UI/UX Project With a Clear Plan

A useful UI/UX design brief does not need to contain every final answer.

It should clearly explain the users, business problem, goals, known requirements, project boundaries, technical constraints, expected deliverables, and approval process.

This gives the design team a stronger starting point for discovery, user flows, wireframes, interface design, validation, and developer handoff.
