Sprint Zero: What It Is, What to Do in It, and When to Skip It

Some Agile teams call the work they do before they begin regular product development as a 'Sprint Zero'. The work could include setting up the development tools, aligning the team, the initial requirements clear, or making sure the technical environment is ready.

Sprint Zero isn't an official Scrum event. The Scrum Guide doesn’t say teams need to have a separate setup sprint before they actually start building a product. Instead, teams are expected to work toward a valuable, usable increment from their first regular sprint.

So, does Sprint Zero make sense?

Sometimes.

It can take a while for a new team or project with complex technical requirements to get organized. But there is a limit to preparation. If a team takes weeks planning, setting up tools and documenting requirements but delivers nothing of use it may be delaying more than it is preventing.

The key is to know what needs to be prepared before development begins and what the team can solve on the go.

Key Highlights of Sprint Zero

• Sprint Zero is an informal preparation phase used by some teams before regular product development.
• The Scrum Guide doesn't recognize Sprint Zero as an official event or require it.
• Common Sprint Zero activities include team formation, initial backlog preparation, technical setup, and agreeing on quality standards.
• A Sprint Zero checklist helps teams identify essential setup tasks without turning preparation into a lengthy planning exercise.
• If a team uses Sprint Zero, it should have a clear purpose and a defined endpoint.
• Alternatives include short planning workshops, technical spikes, and handling setup tasks during the first regular sprint.

Introduction

Let's say a team is about to build a new product. The developers are ready to start coding, but nobody has agreed on what the initial priorities are. Some team members don't have access to the necessary tools, and the product requirements are still taking shape.

If you dive right into development, you'll be unnecessarily confused. But planning every detail for weeks before you ever write the first line of code shouldn't be the answer either.

That's where Sprint Zero comes in.

Some teams have a pre-preparation phase to sort out the basics before they start routine development. They use this time to discuss the product vision, organize the first backlog, set up working agreements, and fix technical issues that would otherwise slow them down.

But it should be kept in mind that preparation can be useful without needing a separate sprint.

The Sprint Zero means helping teams decide whether they genuinely need this additional phase or whether they can complete the same activities while delivering product value.

This article will explore the meaning of Sprint Zero, how it fits with Scrum, and when it's better to avoid it.

What Is Sprint Zero?

Sprint Zero is an informal term for the initial preparations done by a team for product development. It's also known as Sprint 0 in Scrum or Sprint Zero in Agile.

The work that's done during this phase aims on getting the team, tools, and initial plans ready. The team focuses on the groundwork necessary to kick off development, not a finished product feature.

Let's say a team is creating a healthcare app. Developers may need the right systems, a working test environment and a clear understanding of security requirements before they can start work on their first major feature. Also, it is important to know which user problems the team will tackle first.

Such activities can smooth out the first few sprint runs.

Some typical Sprint Zero activities are:

• Discussing the product vision and defining the users of the product.
• Creating and ordering the first Product Backlog.
• Thinking about team roles and working practices.
• Creating development, test, and deployment environments.
• Identifying technical dependencies and risks.
• Setting quality expectations and defining what 'done' means.

Every project doesn’t require the same level of preparation. An established team working on an existing product may already have most of these things in place. A new team is building a complex application may need to spend more time resolving dependencies and understanding the technical landscape.

The preparation must be suitable to the work to be done. Sprint Zero shouldn't become an exercise in planning every feature, resolving every uncertainty, or designing the entire product before development begins.

To see why this distinction matters, consider what is a sprint in Scrum. A regular sprint is a fixed-length period in which the team works toward a sprint goal and creates a valuable increment. Sprint Zero, by contrast, is an informal label for preparation that happens before or around the start of regular delivery.

Does the Scrum Guide Recognize Sprint Zero?

No. The official Scrum Guide doesn't acknowledge Sprint Zero as an event, and it doesn't need teams to complete a separate preparation phase before their first sprint.

The Scrum Guide identifies the five events of Scrum: the Sprint, Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective Sprint Zero isn't one of them.

That doesn’t mean Scrum teams have to start working unprepared. They can discuss requirements, configure tools, explore technical options, and agree on how they will collaborate. The distinction is that these activities don't need to be packaged into a separate Sprint.

There's also an important expectation around the first regular sprint. The team should be working toward a Sprint Goal and trying to deliver a valuable, usable Increment that satisfies the Definition of Done. The first sprint isn't just a warm-up phase to get the project going.

Imagine a team that spends the first two weeks configuring tools, discussing architecture and writing documentation. If it then launches into another sprint to build the real product, the team may have lost an opportunity to test its assumptions and get feedback.

A more practical approach is to do the setup work you need where you need it, and build the rest of your setup work into your normal sprints where possible.

This helps team learning from real product work, instead of waiting until things feel organized..

Why Teams Use a Sprint Zero

Even though Sprint Zero isn't an official Scrum event, teams may find a dedicated preparation period useful in certain situations. The reasons usually come down to people, product uncertainty, or technical dependencies.

New Teams

When a team comes together for the first time, everyone brings their own habits and expectations.

A developer might expect that any change will go through a formal code review. While another could be used for a more informal process. Team members may also have different ideas about communication, decision-making, and how to manage disagreements.

They have a short period of preparation to discuss these differences and agree on a few basic ways of working.

For example, the team could decide how and where to post updates, how to raise blockers, and how to review each other’s work.

These agreements don't need to cover every possible situation. In fact, some are easier to establish after the team has worked together and seen what does or doesn't work.

New Products

Building a product from scratch comes with plenty of unanswered questions. Who will use it? What problem should it solve first? What are some of the most important features?

A sprint zero helps the product owner work alongside stakeholders and the team to answer these questions and set initial priorities.

This can help the team develop a product backlog with possible features, improvements, and other work that's needed to develop the product.

You don’t have to finish the backlog before you start the first sprint. It just needs to have enough meaningful, appropriately understood work for the team to get started.

Technical Setup

Sometimes, the biggest obstacle to starting development isn't a lack of ideas. It's the technology itself.

The team might require access to the repository or a working test environment. Projects, particularly those that involve sensitive data, have security and compliance requirements that must be met before any work can begin.

Clearing away these dependencies sooner rather than later can save you time and frustration.

However, teams should be careful not to build more than they need. Setting up the minimum environment required to build and test an initial feature is often more useful than trying to prepare a complete technical platform for every future requirement

Sprint Zero Activities

The activities a team completes during Sprint Zero will depend on the project. However, four areas commonly deserve attention.

Team Formation and Working Agreements

Before the work gets busy, the team needs a basic understanding of how it will collaborate.

This may involve:

• Clarifying responsibilities and expectations.
• Agreeing on communication channels and how to share updates.
• Setting up code review and knowledge-sharing practices.
• Talking about how decisions will be made and conflicts resolved.
• Looking out for availability constraints and dependencies on other teams.

For instance, a team that operates from locations might find it easier to write down important decisions in a shared space instead of just in meetings.

The aim isn't to create a lengthy rulebook. It's to remove avoidable confusion and give people a workable starting point.

Initial Product Backlog and Vision

The team needs to understand what it's building and why before deciding how to approach the work.

The product owner works with stakeholders and the developers to identify the product's intended outcomes, target users, and initial priorities.

The team then prioritizes the early backlog items by value, risk, dependencies, and opportunities to learn something important.

During Sprint Planning, the team chooses the most relevant work and creates a plan for achieving its sprint goal. The sprint backlog brings together that goal, the selected product backlog items, and the plan for delivering the increment.

There's no need to have every requirement figured out at this stage. The initial backlog should help the team decide what to work on next while leaving room to respond to new information.

Environment and Tooling Setup

Few things are more frustrating for a developer than being ready to work but unable to access the repository or run the application.

To avoid these early roadblocks, the team may have to:

• Set up source control and repository permissions.
• Set up development and testing environments.
• Establish build and testing pipelines that are automated.
• Keep deployment processes and monitoring tools ready.
• Check access to APIs, datasets, and infrastructure that are needed for development.

The team should also test the setup by building and testing a small feature wherever possible.

Just that simple exercise can uncover missing permissions, broken integrations, and configuration problems before they become bigger issues. It also gives the team a practical way to check whether its development workflow actually works.

Definition of Done Draft

The Definition of Done is the commitment attached to the Increment, one of the three Scrum artifacts.

A draft definition of done might cover code review, testing, integration, documentation, security checks, and deployment requirements, depending on the product.

Without having a common understanding, team members can have very different ideas about completion means. So one developer may think a feature is done when the code is written, but another may want to see it tested and integrated before it's done.

That is why the team should establish an appropriate definition of Done and make sure it aligns with any organization-wide standards already in place.

The definition of “done” may evolve and improve as the team learns more about the product. What matters is that quality remains part of everyday development rather than becoming a task to deal with at the end.

Sprint Zero Checklist

A checklist can help the team see what's ready, what still needs attention, and which tasks can wait. The following Sprint Zero checklist is a useful starting point, but teams should adapt it to their actual needs.

How should you use this checklist?

Start by identifying the tasks that could genuinely prevent the team from delivering its first increment.

For example, developers may need repository access before they can work on a feature. But the team doesn't have to perfect its communication practices before getting started. It can learn from the first sprint and make adjustments during the Sprint Retrospective.

The same applies to the product backlog. The team needs a useful starting point, not a complete catalogue of every feature the product might eventually contain.

A simple question can help prioritize: Will leaving this task unfinished prevent us from delivering a valuable first increment?

If so, fix it early. Otherwise, think about doing it in the course of normal development.

How Long Should Sprint Zero Last?

There's no official duration for Sprint Zero because it isn't a defined Scrum event.

If a team chooses to use a preliminary preparation period, its length should depend on the work that genuinely needs to happen before delivery can begin.

An experienced team working on an established product may need only a few focused discussions. A newly formed team dealing with complex infrastructure or significant dependencies may need more time.

Rather than choosing an arbitrary number of days, focus on the outcomes the team needs to achieve.

• Know what needs to be ready. Identify the specific blockers that must be addressed before development can begin.
• Set clear outcomes. For example, the team should be able to build and test a small feature.
• Avoid planning too far ahead. Prepare enough backlog items for the next sprint rather than detailing the entire project.
• Reassess regularly. Check whether the remaining preparation is genuinely necessary.
• Start delivering as soon as practical. Move into regular sprints once the team can work toward a valuable increment.

If a Sprint Zero keeps getting extended because the team wants every requirement or design or technical decision made in advance, maybe it’s worth asking if the extra preparation is helping.

Uncertainty is an inherent part of projects. Teams learn by building, testing, and getting feedback. It’s not about having all the answers before you start the work. The goal is to be ready to start.

Risks of Sprint Zero and How to Reduce Them

Sprint Zero can help a team get organized, but it can also create problems when preparation becomes more important than delivery.

Delayed value delivery: Stakeholders may wait weeks before seeing anything usable. Keep preparation focused on genuine blockers, and look for opportunities to deliver a small, valuable increment early.

Overplanning: Requirements and designs may change once the team starts working with users. Focus on near-term priorities and refine future work as new information emerges.

False confidence: A detailed plan can make a project appear more predictable than it really is. Test important assumptions through prototypes, experiments, and early stakeholder feedback.

Unclear accountability: Team members may be unsure who owns setup tasks or when regular delivery begins. Clarify responsibilities and agree on specific outcomes for the preparation period.

Quality problems later: Teams may postpone testing, integration, and security checks until development is underway. Establish essential quality expectations early and incorporate them into everyday work.

The common thread is that preparation should help the team move forward. If it starts becoming an end in itself, it's time to simplify.

Alternatives to Sprint Zero

Teams don't always need a separate sprint to get organized. Depending on the project, the same preparation can happen through shorter activities or alongside regular development.

1. Lightweight Inception Activities

Get the right people together to have short conversations about the product vision, stakeholder expectations, risks, and initial priorities.

These activities can be before the first sprint or in parallel with ongoing product discovery. The goal is to get the team to agree on what to build next, not to document every single detail of the project.

2. Include Setup Work in the First Sprint

Some setup tasks can be completed along with actual product development.

So, a developer could set up automated testing while also building a small feature that can be tested through the new pipeline.

You can still expect that the sprint has a meaningful sprint goal and that the team is working toward delivering a valuable increment that meets the definition of done. The work that you set up should support that result, not replace it altogether.

3. Use a Technical Spike

A technical spike is a time-boxed period to research or experiment with a specific technical question.

Let's say that the team needs to integrate an external API but isn't sure whether it supports a required feature. A timeboxed investigation can help the team test the integration, understand its limitations, and decide how to proceed.

The important thing is to know what question the spike is meant to answer. A technical investigation can easily get out of hand and go beyond what the team actually needs, if you don’t have a clear purpose.

4. Refine the Backlog Continuously

Instead of preparing every requirement upfront, the product owner and developers can refine upcoming backlog items as they learn more.

This helps the team concentrate on the work that matters now while keeping future priorities flexible. New feedback can then influence what gets built next.

5. Align Preparation With Release Planning

Projects that involve multiple teams, external dependencies, or launch commitments often require more coordination.

The agile release planning guide can help teams to think about milestones, dependencies, and stakeholder expectations without the need to have an upfront plan in place before development can commence.

These options allow teams to plan mindfully without materially delaying delivery of the product.

Sprint Zero in Scaled Agile Settings

Things get more complicated when several teams are working on different parts of the same product.

They may need to coordinate shared infrastructure, security requirements, architecture decisions, integrations, and dependencies on other teams. A little focused preparation can reveal these issues before they impact delivery.

The terminology can vary across Agile frameworks. Some scaled approaches use terms such as Iteration 0 or Iteration 1 for initial planning and preparation. These terms aren't automatically equivalent to Sprint Zero in Scrum.

Consider an organization where several teams depend on a shared integration pipeline. Getting that pipeline ready may be necessary before they can test their combined product. But it doesn't follow that every team must stop development until all architectural decisions have been settled.

A better way is to align around tangible achievements such as a working integration, a defined interface, or a tested deployment process.

It helps to be able to tell the difference between work that needs to be coordinated across the organization and work that a team can complete on its own. This stops one team's unfinished preparation from holding up everyone else.

The challenge for scrum masters and agile practitioners is to create enough structure for teams to work together without making coordination another bottleneck.

Conclusion

Sprint Zero can be useful when a team needs to establish its product vision, organize its initial backlog, prepare technical environments, or agree on working practices before development gets underway.

However, it isn't an official Scrum event, and the Scrum Guide doesn't require a separate setup sprint before product development begins.

The best approach is to identify genuine blockers, complete the essential groundwork, and start delivering valuable increments as early as possible. A practical Sprint Zero checklist can help teams distinguish necessary preparation from work that can continue during regular sprints.

Ultimately, teams don't need to have every detail figured out before they start. They need enough clarity to take the first step, deliver something useful, and learn what to do next.
