Accelerate your product development with our proven Design Thinking approach

Product Design Sprint answers critical questions about a product’s viability and provides material for buy-in and implementation—in just ten days. First developed at Google Ventures, Design Sprint is a “greatest hits” of business strategy, innovation, behavior science, Design Thinking, and more, packaged into a battle-tested process that any team can use.

A shortcut to product validation

Working together in a sprint, Product Design Sprint shortcuts the endless-debate cycle and compresses months of work into a few intensive days. Instead of waiting to launch an MVP to learn if an idea is any good, you’ll get reliable data from a realistic prototype.

The sprint gives you a superpower: To fast-forward to the future to see your finished product and customer response—before making any expensive commitments.

In-person or online

With the help of intuitive, collaborative tools, Windmill has adapted Product Design Sprint to be equally successful online as in-person.

How it works

While the whole process takes ten days, customer involvement is just four days. Better yet, to meet the needs of enterprises and to fit busy schedules, decision-making participation is required only for the first two days.

Before the workshop begins, Windmill conducts preliminary research to define the scope of the sprint.

What is a Design Sprint?

A Design Sprint is a product development workshop powered by Design Thinking, the same framework that underpins all Windmill’s product design success. With Design Thinking, we work with you to empathize with the customer, define the target problem, generate ideas, make a prototype, and test the solution.

How do you conduct Design Sprints remotely?

To adapt to pandemic working protocols – or simply if a customer prefers to – Windmill conducts online Design Sprint workshops using Miro. Miro is a real-time collaboration tool that allows a whole team to engage in ideation sessions. Windmill has hosted more than 50 online Design Sprints in the last few years.

Why conduct Design Sprints following Google Ventures methodology?

Design Thinking is a tried-and-tested product development methodology. It provides a way of shortcutting development cycles, bypassing the build phase, and allowing teams to design, test, and iterate at pace.

What are the Design Sprint’s deliverables? Will I have a prototype I can give to developers?

The two key deliverables of the Design Sprint are a prototype and a business case document. The report is packed with insight for sharing with investors and potential customers.

What if I don’t know which development platform my product will use?

Ahead of the workshop, Windmill will conduct preliminary research to define the scope of the sprint. However, we do not want to constrain our design work by technical details: usability and product features are the priority.
