01Overview

What a design sprint is for

We run a design sprint around a product question you need to answer before choosing the next development scope. The work can explore a new concept or a feature inside an existing product. We agree the question and the evidence needed to assess it before prototyping begins.

  • A prototype and a decision readoutYou get the selected prototype, findings and a recommendation for the next step. Your decision owner uses that evidence to choose a build, refine the direction or choose a different scope.
  • Content and fidelity with a purposeWe choose the detail the test needs, using your copy, permitted sample data and relevant flows. Audience access and recruitment are agreed with you as part of the scope.
  • One assumption, named firstWe name the assumption under test and the decision it informs. That keeps the prototype focused and makes the limits of its findings clear.
  • The right starting pointA UX audit assesses an existing experience. Product design and development carries an agreed product direction into software delivery. We help you choose the scope that answers your current question.

Sprint with us, sprint in-house, or skip straight to the build?

Choose the route around the decision you need to make and who will facilitate the work. Research without a prototype can establish needs or explore a market; a prototype helps test a selected interaction or concept. For engineering feasibility, technology advisory provides a separate assessment.

Agree the window with your decision owner

Bring the competing ideas and the people who can approve the next step. We agree the selected test and readout before starting. Most engagements start within two to four weeks.

Talk about the sprint

A design sprint settles a product decision with evidence. In a fixed window, we turn the competing ideas into a prototype and put it in front of your audience. When the team already agrees on the direction, we go straight to design.

04Capabilities

What you get

The sprint scope selects the capabilities needed to test your question and prepare the next decision.

  • Design sprint facilitation

    Framing the riskiest assumption

    The single belief under test

    We frame the riskiest assumption as a testable question. The written brief names the decision it informs, what evidence would help and the limits of the selected test.

  • Rapid prototyping

    We build clickable prototypes at the fidelity the question needs. You supply relevant copy, permitted sample data and product context; we use them to make the selected journey understandable to target users.

  • Concept validation and user testing

    Concept validation with real users

    What they do, not what they say

    We agree who the target users are and how to reach them. Selected sessions capture how they use and interpret the prototype, with findings and limitations reported against the question under test.

  • Build scoping and estimation

    Sprint to scope

    Scope, sequencing, risks

    We translate the findings into a recommendation for the scoped next build, further research or a revised direction. Where you choose a subsequent product build, we agree its requirements, sequencing, risks and estimate before development begins.

  • Rapid wireframe iteration

    We use wireframes to compare layouts and interaction logic when that level of detail answers the question. Visual foundations and a reusable component library can be chosen as a separate design-system scope.

  • Mobile app prototyping

    We select mobile journeys and the device context relevant to them. The prototype and test can explore navigation, content and interaction on a phone, with fidelity agreed for the decision you need to make.

  • Prototype to production handoff

    We prepare the prototype and findings for development, together with the agreed scope for the next phase. When you choose a build, we agree the handover and engineering work, including the acceptance criteria for production deliverables.

05Stack

Tools for the sprint and the build that follows

We use Figma and research methods during the sprint, then select frameworks for any subsequent build. Nielsen's heuristics are a standard method for reviewing usability, and the development tools below are chosen for the product's requirements.

06Engagement

How you engage us on a sprint

Choose the engagement around how often your roadmap needs audience evidence for product decisions. There is no minimum engagement period.

  • A fixed-window sprint

    Start here

    We agree the question, window, audience access, prototype and readout before starting. The recommendation follows the evidence collected, including any uncertainty that needs further work.

    Best when

  • Sprint, then build

    Straight through

    Run the sprint first, then choose the development scope from its findings. We can take the prototype into development with a separately agreed estimate, acceptance criteria and handover.

    Best when
    You want a partner for the sprint and the subsequent agreed build
    You pay
    Billed hourly, quoted per project
    Typical start

A sprint that already ran

Review the existing findings before planning another sprint

We review the prototype, session notes and decision from the earlier sprint. That shows what the evidence supports and which questions remain open before you choose further work. A UX audit provides a focused assessment when the question concerns an existing experience.

07Industries

Industries we prototype for

Industry rules shape the journey worth testing. We scope the prototype around your users, operational constraints and the information that can be shown in a session.

Deepest expertise

Logistics and transportation

A quoting or dispatch concept can test the decisions people make as an order moves through operations. We select representative scenarios for the moving-order workflow from your operational rules.

Deepest expertise

Hospitality and leisure

A booking journey can test how customers understand available appointments and make a selection. For the subsequent build, availability can depend on real-time data from the backend system.

EdTech and learning

Select the learner or administrator journey the product decision concerns. A test-preparation flow can explore how the intended audience understands the content and moves through the selected task.

E-commerce

We select the prototype's B2B or B2C journey and sample product information around storefront, stock-management and middleware constraints, drawing on our work for a European manufacturer whose Shopify shops in seven EU countries connect to Microsoft Dynamics ERP stock management.

Healthcare

A health-monitoring journey needs a defined audience and clear permissions for content and sample data. We agree what can be shown and how participants can be reached before selecting the test.

Warehouse management

For a new warehouse-management application, select the operator task and the surrounding systems the concept must account for. We agree which interactions to represent and which integration questions belong in the later engineering scope.

Bring the product decision you want to test

Tell us the concept or feature you are considering and the evidence you already have. We will discuss the question a sprint could answer and the scope needed to answer it.

11Questions

About prototyping and design sprints

The prototype's level of detail follows what you need to learn from the selected journey.

A design sprint is a facilitated, fixed-window process for testing a selected product question through a prototype and audience evidence. We frame the assumption, prototype the relevant journey and give your decision owner findings and a recommendation.

Rapid prototyping is one part of that work. Business analysis defines requirements and scope; product design and development takes an agreed direction into software delivery. We choose the engagement around the question you need answered.

You receive the agreed prototype, findings and decision readout. We define those outputs and their acceptance before the sprint begins.

The readout can recommend a build, a revised direction, a different scope or further evidence. Development follows with its own requirements, estimate and acceptance criteria, and where it fits, our MVP in 6 Weeks offer can be the next build. Handover, access and IP terms are agreed for your engagement.

We quote a fixed-window sprint per project against the agreed scope. There is no minimum engagement period.

The scope accounts for:

  • The product question and flows selected for the prototype.
  • The fidelity and content needed for the test.
  • Audience access, recruitment and the selected research methods.
  • The readout and handover you need.

Fixed-price work is outcome based and quoted per project. Time-and-materials work is billed hourly and quoted per project; team extension is billed monthly per team member. We agree the appropriate model with you.

We agree the sprint's length before starting, based on the selected question, prototype and test scope.

Sessions can be scheduled across the chosen window to account for participant and audience availability, including a window spanning several weeks where that suits the scope. We agree the readout date and decision-owner involvement as part of the plan. Most engagements start within two to four weeks; that is a typical start window, not the sprint's duration.

We agree which system interactions the prototype needs to represent. Selected integrations may be simulated to test the user journey; a clickable prototype does not establish that the production integration works.

Bring the relevant system constraints and permitted sample data when we frame the question. If technical feasibility is the decision you need to make, we scope that assessment separately from audience testing.

The prototype represents the selected journey at the fidelity needed to test it. That may mean wireframes for layout and flow, or more detailed clickable screens with relevant content.

We identify simulated behavior and the limits of what target users can do. Production code, live integrations and a finished application are separate deliverables, agreed when you choose a development scope.

We report what the test shows and recommend the next step. Findings can support a pivot, a decision to stop the selected direction, or further research before you commit to a build.

An uncertain result is useful when its limits are clear. We distinguish an observed problem from a broader conclusion about the concept, and identify what would need to change or be tested next. Your decision owner chooses the next scope from that readout.

We need access to the decision owner and participants who can explain the product, audience and relevant constraints. We agree their involvement and session schedule before starting.

Your side provides:

  • The decision being considered and the evidence already available.
  • Product rules, relevant copy and permitted sample data.
  • Access to target users or the agreed recruitment support.
  • Review of the selected flow, agreed outputs and final readout.

The decision owner approves the next step from the findings and recommendation.

Yes. We can frame a selected feature inside an existing product and test its relevant journey with the intended audience. Existing product rules and user behavior help define what the prototype must represent.

For a whole new application, we still select the question and slice to test rather than treating a sprint as validation of every feature. A UX audit assesses an existing experience; our catering-application audit used user testing, interviews and Nielsen heuristics to produce findings and recommendations.

Compare the proposed question, responsibilities and outputs, then inspect the evidence relevant to that work.

Ask each partner to explain:

  • Who facilitates, prototypes and runs the selected research.
  • How audience access, participant involvement and recruitment are agreed.
  • What the prototype represents and how findings and uncertainty are reported.
  • How outputs are accepted and how any subsequent build is scoped.

We hold ISO 27001:2022 and ISO 9001:2015 certifications, renewed through a multi-stage audit with Quay Audit UK. Our guide to choosing an MVP development company helps assess a subsequent build partner.

A design sprint fits when a selected product decision would benefit from a prototype and audience evidence, and the decision owner can participate in choosing the next scope.

Capable internal facilitation can serve the same purpose. Research without a prototype can explore needs; focused interface design can develop a direction already chosen. Technology consulting and advisory assesses engineering feasibility, while product design and development delivers an agreed product scope.

We use the initial conversation to identify the evidence you need and the work that can provide it.
