Design Sprints are week-long events where teams come together, collaborate, and embark on a journey to explore and solve a problem through design, prototyping, and testing ideas with customers.
Created by Google Ventures, this robust design sprint methodology effectively validates ideas. But diving into this event can be intense.
Yet, several successful startup stories across different industries have credited their achievements to the use of design sprints.
To achieve similar success, it’s crucial to follow Design Sprint best practices and maximize the potential of this time.
When should we do a Design Sprint?

If you encounter any of these situations, it’s worth considering involving your team in a Design Sprint:
- When you face a challenge or problem with no obvious solution.
- A quick solution is required.
- You are currently encountering a problem that requires a deeper understanding of it.
- You have a solution in place, but still lack clarity on the product development process, your client, or your competition.
- The issue you’re dealing with is large enough to require collaboration from various teams.
- When you’re in search of an innovative, out-of-the-box idea.
Every business is unique, and the scenarios will differ.
When should we not do a Design Sprint?
However, a design sprint may not be suitable if:
- The scope needs to be narrower.
- A validated product design concept may have already been agreed upon, and all the team needs to do is conduct it.
- Essential team members are missing.
- The problem you’re encountering is unclear.
Take this into account when deciding whether or not to start a Design Sprint.
How to conduct an effective Design Sprint

Design sprints provide many benefits, but thorough planning is crucial to fully leverage them.
Even after the sprint ends, there will still be work to complete. Follow this roadmap to ensure you’re using Design Sprint’s best practices.
Before starting
- You and the client must thoroughly understand the purpose of the Design Sprint process and be precise about the goal to be achieved.
- Recruiting a multidisciplinary team of 4-7 members, led by the sprint master, makes team management easier.
- A typical design sprint team is composed of a facilitator, a designer, a developer (who may be a full-stack developer or a team of front-end and back-end specialists), and a Product Owner.
- After recruiting the team, appoint one member as the decision-maker with the final say on all important matters.
- Book a full-time schedule for the week, usually six to eight hours, considering different time zones.
- Engage four additional experts on the first day to enlarge the perspective on the problem.
- If the Design Sprint is being conducted for a client, enlisting an expert from their team is essential.
- You must have all the necessary tools for every step of the Design Sprint process. Your team must share notes and work with prototyping tools.
In LoopStudio, we always have a preliminary meeting to:
- Display the calendar to the customer so they know the process: dynamics, methods, timeline, etc.
- Explain to the client the key dynamics and what to expect each day, along with the main objective and examples of the results.
- Provide the client with a demonstration of the tools so that they can become familiar with them.
- Present the members of the Design Spring. Each one should introduce themselves.
- Get the Miro board ready for the upcoming Design Sprint.
1. What to do in the first week

Before we begin, remember to keep everyone on the agenda, focus on the most crucial aspects of the problem, and foster open communication.
A. 1st day – Map
On the first day, we must define the problem, understand its context, and gain insights into the business and the users. The output for day one is to complete the user map.
Activities for Day 1 include:
- Define a long-term goal: Where do we see the product or the business in two years? Each sprint participants must share their vision, and then, through a structured decision making process, the team collectively decides on the best goal.
- Sprint Question: What challenges are we currently facing? Each member is encouraged to contribute 2 or 3 questions about these challenges. Everyone should vote for the best 2-4 questions. The purpose is to find potential weaknesses by thinking about what could go wrong.
- User journey mapping: Building a visual representation from the initial action to the final goal, considering the different users. The user journey should consist of 5-15 simplified steps.
- During the day, a designated team member should begin searching for user testers, as you will need to test the solution we’ll build later on.
- Expert Talks: Interview the guest experts to cover all technical doubts and achieve a detailed understanding of the problem. Take notes using the “How Might We” methodology.
- Homework: After the sprint session, participants should search for references to solutions from other businesses or products.
B. 2nd day – Develop possible solutions
Day two is creatively challenging, as the output is to find potential solutions from each sprint member.
Activities for Day 2 include:
- Demo presentation: Based on the homework from day 1, each member will present their identified solution. This task generates original ideas. Later, we will consider whether we will use them or not.
- Crazy 8s: Each person will fold a sheet of paper into eight squares and sketch a different possible solution within eight minutes.
- Developing one solution each: After playing Crazy 8s, team members will choose the best idea and develop it further with additional sketches and descriptions.
C. 3rd day – Choose the best solution
On Day 3, the team works together to improve ideas and apply problem solving strategies to select the most effective solution for the user journey.
The output for today is to develop a storyboard to build the prototype the following day.
Day 3’s activities include the following:
- Presentation: Each person shows their sketch and explains how the design works.
- Voting: Team members vote for the best solution using stickers. The sketch with the most stickers wins.
- Storyboards: The team works together to create a storyboard that shows how the user will engage with the selected design. This sequence begins with the user’s initial interaction with the product and ends with a positive result. We make sure to document all the details carefully so that the designer has all the information needed when starting the prototyping phase, keeping the big idea consistent.
D. 4th day – Design and build a prototype
Day 4 is where the team’s hard work really pays off, as everyone collaborates to turn ideas into a functional prototype.
The output is to have a prototype ready for testing.
The most crucial activity of Day 4 is:
- Prototype building: The prototyping designer will begin turning the wireframe into an interactive prototype with the rest of the team’s ideas and direction.
If there are multiple designers, dividing and combining the work might be beneficial.
E. 5th day – Design and build a prototype
We must prepare for user testing as we continue designing and working on our prototype.
Confirm the individuals selected for testing and write the script to conduct the same testing. This script provides clear guidance on presenting prototypes to users, ensuring that essential insights are gained.
Before conducting interviews with real users, testing the prototype by simulating end users is essential. This internal team test must be completed before the interview day.
F. 6th day – Testing
Finally! The team validates the prototype with real users to discover usability issues and necessary feedback.
The goal for the final day is to gather all the positive and negative impacts of the prototype.
To conduct testing, we perform the following activities:
- User-testing: Invite five people to test the prototype and gather their feedback using a form. If you want to know about focus points, you might want to ask specific questions.
- Client consultations: If you’re working on a client project, invite critical members of their team separately from the users so they can participate and share their insights.
- Notes: During the interviews, we set a board to take notes.
- Identify Patterns: After collecting all information, group similar notes to uncover insights.
These insights help ensure a successful design sprint by validating the prototype against real user needs
2. What to do in the second and third weeks

At LoopStudio, we create our own system for the following weeks. We have dedicated time to enhancing it, ensuring robust deliverables to kickstart the development stage as quickly as possible.
We will focus on refining the prototype during the second and third weeks.
This refinement process will be based on the valuable insights gathered from user interviews and the detailed notes provided by each team member.
Based on the interview feedback, a meeting is scheduled to prioritize the items that need improvement, ensuring each adjustment contributes to the client’s broader business strategy.
This week aims to produce specific deliverables that will serve as a bridge between the Design Sprint and the Development Sprint.
A. Determine product scope and vision
It is crucial to validate and document all requirements for future versions of the prototype, ensuring that:
- Every relevant requirement is linked to a specific task.
- There are no tasks that are irrelevant to the business.
- Each task is assigned a priority, potentially categorized as MVP, release 1, and release 2.
- What is not included as part of the MVP version or phase 1 is added to a backlog along with suggestions for prioritization.
Capturing all the requirements for a prototype can be challenging, so using User Story Mapping (USM) is recommended.
This technique, widely used in agile project management, helps organize user stories into functional categories and maintain clarity.
B. Determine the technical feasibility
It’s time to analyze how we will develop each functionality. There are two scenarios to consider:
- For a new project, we need to decide on the technology stack and architecture.
- For an existing project with a new feature, the technology stack and system architecture may already be defined.
In LoopStudio, we involve the client’s technical team, ideally, the Tech Lead, to gather more information and ensure the security of our decisions.
C. Define the team and time needed
First, map the requirements and find a suitable solution. Then estimate the effort and define the necessary team.
Use a detailed bottom-up approach for estimating tasks and a high-level top-down approach to ensure a global perspective.
Review any disparities between the two estimates and reach a consensus among team members.
Consider test cases and identify parallelizable tasks to optimize the team’s capacity.
3. Make the proposal
As the last stage of the process, we create a proposal that includes all the points mentioned above.
This ensures that the client finishes the process with a solid deliverable and enough information to use in future stages, whether with LoopStudio or independently.
What sets LoopStudio apart is our commitment not only to creating prototypes but also to providing the complete framework and resources necessary to turn them into fully realized MVPs.
By equipping our clients with the essential tools, we ensure they feel confident and prepared for the next stage of their journey.
FAQ
