The 3 Stages of Product Development Where Design Sprints Actually Work

And why timing — not just the method — determines the impact

Not every problem needs a Design Sprint.

But some do — and if you miss those windows, you risk wasted cycles, misaligned teams, and products that don’t land.

At Design Sprint Academy, we’ve facilitated sprints across industries — from global banks and car manufacturers to e-commerce platforms and SaaS scaleups. And one question always comes up: “When’s the right moment to run one?”

Here’s the short answer:

You can run a Design Sprint at any stage of the product lifecycle — from early discovery to roadmap planning to delivery.

But here’s the truth:

The earlier you run it, the bigger the impact.

This article breaks down the three key stages where Design Sprints create value — and what kind of outcomes you can expect from each. All based on real challenges we’ve tackled with clients over the past eight years.

1. Early Discovery Phase

(Where the Impact Is Greatest)

This is where strategy takes shape. You haven’t built anything yet. You’re still exploring opportunity spaces, identifying gaps, and deciding where to play. A Design Sprint here helps you align leadership, reduce ambiguity, and de-risk your most important bets — fast.

Examples from sprints we facilitated:

Publishing Company (Print Media)

• Problem: The print audience was aging, and younger readers weren’t engaging at all.
• Challenge: “How might we transition from print to digital in a way that attracts younger audiences while retaining our loyal, high-fidelity readers?”

AI Traffic Safety System

• Problem: Traffic engineers were skeptical of an AI system they didn’t fully trust or understand.
• Challenge: “How might we design an efficient and reliable AI system that traffic engineers trust and use to enhance traffic safety?”

2. Roadmap Definition & Prioritization

(Where You Avoid Building the Wrong Thing)

This is when product managers decide what makes it onto the roadmap. Most teams rely on a mix of intuition, stakeholder input, and historic data. A Design Sprint introduces external validation — helping teams make smarter, faster calls about what’s worth building.

Examples from sprints we facilitated:

Financial Services Institution

• Problem: Customers didn’t understand their credit card options and defaulted to outside advice.
• Challenge: “How might we make it easy and intuitive for users to find the best card for their needs, reducing the need for outside opinions and complex comparisons?”

Car Manufacturer

• Problem: Rising privacy concerns made it difficult to secure consent for vehicle data sharing.
• Challenge: “How might we increase data-sharing consent among connected car drivers, while ensuring compliance and building brand trust?”

E-Commerce Platform

• Problem: Sellers lacked the support needed to fully activate and sell on the platform.
• Challenge: “How might we leverage AI and provide sellers with the right educational support in context and at the right time, so they can confidently use our platform to drive sales?”

3. Build & Delivery Phase

(Where Sprints Can Still Unblock You)

Even in execution, a Design Sprint can help. The impact is more tactical than strategic — but if you’re stuck on usability, adoption, or internal alignment, it’s a fast way to get clarity and move forward with confidence.

Examples from sprints we facilitated:

Apparel Sizing Technology Company

• Problem: Customers didn’t trust the sizing experience, leading to high return rates.
• Challenge: “How might we use our 3D technology to enhance the sizing and body measurement experience, ensuring privacy and building user confidence in the process?”

Restaurant Table Reservation Platform

• Problem: Restaurant owners struggled with onboarding, which delayed adoption and bookings.
• Challenge: “How might we redesign the onboarding experience for restaurant owners on our table reservation platform to make setup quick and intuitive?”

These sprints helped unblock product teams in the middle of delivery — improving adoption, clarifying usability, and reducing late-stage friction.

But there’s a reason many teams only discovered sprints at this stage.

Why Design Sprints Were Stuck in the Build Phase

In the early years, Design Sprints were primarily championed by designers.

And that made sense — the process felt familiar. It drew on techniques they already knew: brainstorming, sketching, prototyping, user testing.

But here’s what often happened:

Designers ran sprints on smaller, tactical challenges — things within their reach but outside their authority to truly own. Most of the time, they operated in the refinement or build phases of the product cycle.

They didn’t always have the mandate to slow things down.

Or the influence to bring stakeholders together.

Or the runway to address bigger strategic questions.

As a result, they were often stuck trying to prove the value of a sprint in environments focused on speed and delivery. And when the challenges weren’t bold enough, the impact wasn’t either.

Now, a decade after their creation, Design Sprints remain underutilized by the very people who stand to benefit most: Product leaders.

Leaders who do have the authority to reframe problems, mobilize teams, and use Design Sprints not just as a method — but as a way of working.

A way of de-risking bold ideas and validating direction before things get expensive.

So When Should You Use a Design Sprint?

You can apply it at any point in the journey —

but the earlier you do, the more leverage you gain.

• Use it late (during delivery) and you’ll fix what’s broken.
• Use it midstream (during planning) and you’ll avoid building the wrong thing.
• Use it early (during discovery) and you’ll shape the future before it’s written.

If you’re a product leader — this is your move to make.

🚀 Want to Bring Design Sprints Into Your Organization?

In 2025, most of the companies requesting Design Sprint training for their teams aren’t startups. They’re in banking and construction. This year alone, we’ve worked with teams at the World Bank, HSBC, and Turner Construction Company — running sprints to align stakeholders, reframe complex challenges, and accelerate decisions in environments where innovation isn’t optional.

Is it a sign these industries are gearing up for bold change? That they’re more willing to challenge the status quo?

Maybe.

What’s clear is this:

Design Sprints are no longer just a designer’s tool.

They’re becoming a leadership tool.
