Product Redesign Services
ANODA traces blocked journeys and redesigns the flows, screens and states around them, so customers finish work more easily while keeping the familiar parts they rely on.
- For live products
- One defined area that must work better
- 8–16 weeks
- For an agreed scope
- Reworked flows
- Keeping what people rely on
- A transition handoff
- How the change reaches users
In short
A better product, without losing what people rely on.
What's included
- A map of the current state
- Reworked flows
- Redesigned interfaces
- A transition handoff
Helps you decide
- What to change
- What to keep
- In what order to release it
Where it stops
Tells you what is wrong and what to fix first.
Product Redesign
Makes the change and plans how it reaches users.
Not included
- Backend rebuilds or data migration
- Changing everything at once when phasing is safer
A clearer version of the product you have
-
Current-state map
The existing journeys, roles, constraints and friction in the agreed area.
-
Reworked flows
A proposed structure and task paths, with changes to the current experience made explicit.
-
Redesigned interfaces
Screens, components and essential states for the selected workflows.
-
Transition handoff
Behaviour notes and implementation guidance for the engineering team.
The handoff identifies what changes and what should remain stable. Implementation and a full design-system rebuild are separate scopes.
Start from the product in use.
A redesign changes a product people rely on today, so it begins with what they do in it now and what must not break.
Roles
- Existing users
- Admins
- Support
Key tasks
- The journeys people repeat every day
- Where they get stuck or work around the product
- What support is asked about most
-
Current state
The journeys, patterns and constraints of the product as it is used today.
-
Workflows
Each key task end to end, across roles, including the steps between screens.
-
Prototype and validation
Connected journeys the team and, when scoped, users can walk through.
-
Interface and components
Screens, components and interaction details, consistent across the product.
States every screen is designed for
- Empty
- Loading
- Error and recovery
- No permission
- Partial data
- Responsive layouts
- Keyboard and screen reader
What stays
- Workflows people rely on
- Data, integrations and URLs
- Terms and patterns users already know
What changes
- Navigation and structure that no longer fit
- Screens that hide the next step
- Inconsistent patterns and states
Engineering handoff. Redesigned screens with the transition plan: what ships first, what changes for existing users, and what engineering needs for each step.
An existing product we redesigned
Forever Beauty shows how an audit becomes a clearer live product: reworked navigation, redesigned iOS and Android screens and light and dark UI around the existing backend, with a kit and handoff for the client’s engineers.

When product redesign is the right step
-
A product in use
People already depend on its main workflows.
-
A known area
You can name the journey or product area to improve.
-
Constraints to respect
Your team can share the current system and engineering limits.
A different starting point
- Problems not yet diagnosed UX Audit
- New product to design UI/UX & Product Design
- Only shared components need work Design Systems
Stop paying for workarounds in a product you already built
Show ANODA the journey users repeat, the point they struggle with and what your engineers need to preserve. We will turn that friction into a clearer product, with an explicit plan for the changes your team can deliver.
How the engagement works
What we need from your team, who does what, and what happens after the handoff.
What we need to start
- Scope
- The product area or workflows that need to change.
- Context
- User context, existing evidence and technical constraints.
- Decisions
- Someone who can review priorities and resolve trade-offs.
- Engineering
- Capacity that exists or is being planned for the direction.
Who does what
- ANODA
- designs the structure, the flows, the screens and their states, and documents the decisions your engineers need.
- Your team
- shares context and constraints, reviews priorities and takes the agreed direction into implementation.
After the design work Implementation reviews and frontend delivery are scoped separately when needed. A design system that needs substantial work is its own scope, separate from the agreed product-design work. Usually 8–16 weeks for an agreed scope.
In the client's words
Our product had become outdated, and we knew it needed a substantial rethink. ANODA started with a thorough UX audit that helped us understand where users were struggling, which parts of the experience needed the most attention, and what to prioritise. They then turned those findings into a redesign that felt like a huge step forward—modern, intuitive and visually polished. We appreciated how they challenged what wasn’t working while respecting the technical constraints of the existing product. The transformation went well beyond appearance; it gave us a clearer, more cohesive product and a direction we were excited to move forward with.
Which part of your existing product needs to change?
Share the current workflows, user friction and engineering constraints. We will discuss the redesign scope and what needs to stay stable.

Questions about product redesign
When should we redesign an existing product instead of designing a new one?
Choose Product Redesign when people already depend on the software and the task is to improve its existing journeys, navigation or interfaces while respecting current constraints. Digital Product Design is a different starting point for a new product or substantial new product area. Website Redesign covers a marketing website rather than a signed-in product.
How does product redesign differ from a general UI/UX engagement?
UI/UX Design covers interaction and interface design for defined software workflows. Redesign starts from a product already in use: what users do today, what needs to change, what must stay stable and how the engineering team can introduce the change. The agreed scope may cover one journey rather than the whole product.
What does a product redesign engagement include?
A current-state map of the agreed area, reworked flows, redesigned interfaces and transition handoff. We connect each change to the user’s task, compare the old and new paths and use review or testing to settle the decisions that matter before engineering builds them.
How do you preserve critical workflows while changing the experience?
We identify the workflows, terms, components, data and integration constraints users rely on, then make each change explicit. The handoff gives engineering the screens, states and continuity requirements for each step; we can plan the release in phases with your team.
What access, data and stakeholders do you need?
The current product or a representative walkthrough, its priority workflows and roles, known friction, support feedback or research when available, and engineering constraints. A product decision-maker reviews priorities and an engineering contact checks dependencies. The access and evidence required are agreed for the selected area.
What deliverables and engineering handoff should we expect?
The current-state map, proposed task flows, selected screens and essential states, plus behavior notes and implementation guidance. Engineering sees what stays stable and what changes. We agree the prototype, validation and phased implementation needs before starting, so the handoff fits the work your team will build.
What determines scope, timeline and price?
The journeys and user roles affected, interface states, platforms, existing-system constraints, evidence gaps and review cycles determine the effort. We agree the area, dependencies and acceptance criteria before proposing a schedule and fee. A full-product replacement is not assumed when a smaller coherent area is the agreed task.
What is excluded unless separately scoped?
We agree a new brand identity, full design-system rebuild, website redesign or software implementation as separate work when needed. Interface redesign works around the backend and data constraints your team maintains; research, recruitment and validation are scoped to the decisions the redesign needs to resolve.
