What is Scrum Methodology? Beginner’s guide

Imagine a team working on a complex project where requirements keep changing, and priorities shift. If you are wondering what Scrum is, it is a lightweight Agile framework that helps teams manage this uncertainty through short, focused cycles called Sprints.

Instead of planning every detail upfront, teams plan work, review progress, gather feedback, and adapt as they learn.

If you are new to Agile and want to see how Scrum works in practice, this guide covers the Scrum framework, its accountabilities, events, artifacts, and values. You will also learn how Scrum helps development teams deliver value incrementally and how it compares with Agile and Kanban.

What is Scrum methodology?

Scrum is an Agile framework for managing complex work through short, iterative cycles called Sprints. It helps teams organize work, inspect progress, gather feedback, and adapt as they learn. Three Scrum artifacts provide transparency into the work and product, each with a corresponding commitment that guides decisions and progress:

• Product Backlog → Product Goal: Defines the long-term objective the product aims to achieve.
• Sprint Backlog → Sprint Goal: Establishes the single objective for the current Sprint and guides the work selected to achieve it.
• Increment → Definition of Done: Sets the quality criteria that the Increment must meet to be considered usable.

These elements help Scrum Teams stay focused on product goals, work toward a clear Sprint objective, and maintain quality as they deliver usable Increments. Scrum is particularly useful in software development, where requirements and priorities can change as teams gather feedback and learn more about the product.

Why is Scrum important in software development?

In software development, short Sprints help teams deliver usable work and review progress regularly. Feedback from Sprint Reviews can inform future priorities, while Sprint Retrospectives help the Scrum Team identify ways to improve its effectiveness.

The Scrum Master is accountable for establishing Scrum as defined in the Scrum Guide and helping the Scrum Team understand and apply its principles and practices. Through coaching, the Scrum Master helps the team improve its effectiveness, address challenges in how it works, and continuously improve its way of working.

Collaboration among cross-functional Scrum Team members helps them respond to changing requirements, incorporate feedback, and deliver outcomes that address customer needs. Through regular inspection and adaptation, Scrum supports continuous improvement and helps teams deliver value incrementally.

How does Scrum methodology work?

The Scrum process organizes work into Sprints, which last one month or less. Each Sprint is a container for four events: Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective. Together, these events help the Scrum Team plan its work, track progress, inspect outcomes, and adapt its approach. Inspection and adaptation happen throughout the Sprint, not only after development is complete.

A typical Sprint involves the following activities:

• Maintain the Product Backlog: The Product Backlog contains the ordered work needed to improve the product. The Product Owner manages it, incorporating new information and feedback to keep priorities aligned with the Product Goal.
• Plan the Sprint: During Sprint Planning, the Scrum Team establishes a Sprint Goal. Developers select Product Backlog items for the Sprint through discussion with the Product Owner and create a plan for delivering the work.
• Develop the Increment: Developers work toward the Sprint Goal and create an Increment that meets the Definition of Done. During the Sprint, they use the Daily Scrum to inspect progress toward the goal and adapt their plan as needed.
• Inspect the outcome: During the Sprint Review, the Scrum Team and stakeholders inspect the results of the Sprint, discuss changes in the environment, and consider what to do next.
• Identify improvements: During the Sprint Retrospective, the Scrum Team examines how the Sprint went in terms of people, interactions, processes, and tools, then identifies improvements to apply in future work.
• Continue with the next Sprint: The next Sprint begins after the previous one ends. The team builds on what it has learned while continuing to work toward the Product Goal.

The Scrum Guide specifies that a Sprint lasts one month or less. Two-week Sprints are a common choice, but Scrum does not require a specific duration. Shorter Sprints provide more frequent opportunities to inspect progress, gather feedback, and adapt plans.

Scrum relies on empirical process control: teams use transparency, inspection, and adaptation to make decisions based on what they observe. This allows them to adjust their approach as they learn more about the product and its requirements.

What are the 3 Scrum accountabilities?

A Scrum Team has three accountabilities: the Product Owner, the Scrum Master, and the Developers.

Product Owner

The Product Owner is responsible for maximizing the value of the product by ensuring the Scrum Team focuses on the most valuable work. This includes communicating the Product Goal and ensuring that Product Backlog items are clear, ordered, and managed effectively.

The Product Owner helps the team maintain a clear view of what work is most valuable, ensuring alignment with project stakeholders.

Scrum Master

The Scrum Master is accountable for establishing Scrum and helping the Scrum Team improve its effectiveness. They support the team in understanding and applying Scrum, coach team members and stakeholders where needed, and help address impediments to progress.

If you are considering this career path, reviewing Scrum Master interview questions can also help you prepare for the role.

Developers

Developers are the people in the Scrum Team who are committed to creating any aspect of a usable Increment each Sprint. They create the plan for the Sprint, maintain quality by adhering to the Definition of Done, adapt their plan daily toward the Sprint Goal, and hold one another accountable as professionals.

Developers can have different areas of expertise depending on the product and the work involved, embodying the agile Scrum methodology within the development process.

What are the 5 Scrum events?

Scrum includes five events. The Sprint contains the other four events and provides the overall cycle for the work of the team.

1. Sprint

A Sprint is a fixed-length period of one month or less in which the Scrum Team works toward a Sprint Goal and creates a usable Increment.

2. Sprint Planning

Sprint Planning begins the Sprint. The Scrum Team discusses why the Sprint is valuable, what work can be selected, and how the chosen work can be completed. The outcome includes a Sprint Goal and a Sprint Backlog, which contains the selected Product Backlog items and the plan for delivering the Increment.

3. Daily Scrum

The Daily Scrum is a short event where Developers inspect progress toward the Sprint Goal and adapt their plan for the next day. It is intended to help Developers coordinate their work rather than function simply as a status meeting. Typically, these meetings last about fifteen minutes.

4. Sprint Review

During the Sprint Review, the Scrum Team and stakeholders inspect the outcome of the Sprint and discuss what has changed. The discussion can help determine future adaptations to the Product Backlog and improve team collaboration.

5. Sprint Retrospective

The Sprint Retrospective allows the Scrum Team to examine the Sprint and identify useful improvements. The team reviews its processes, interactions, and tools to identify changes that could improve the effectiveness and efficiency of the Scrum Team.

What are the 3 Scrum artifacts?

Scrum has three artifacts that provide transparency around the work and product.

Product Backlog

The Product Backlog is an ordered list of what is needed to improve the product. It evolves as the product and its environment change.

Sprint Backlog

The Sprint Backlog contains the Sprint Goal, the Product Backlog items selected for the Sprint, and the plan for delivering the Increment. It gives Developers a current view of the work they are undertaking.

Increment

The Increment is a usable, concrete step toward the Product Goal. It must meet the Definition of Done. A Sprint can produce multiple Increments, and multiple Increments can be created during a single Sprint.

What are the Scrum values?

The five Scrum values are Commitment, Focus, Openness, Respect, and Courage.

• Commitment: Scrum team members commit to achieving their goals and supporting one another.
• Focus: The team concentrates on the work needed to make progress during the Sprint.
• Openness: Team members and stakeholders remain open about work, challenges, and progress.
• Respect: People recognize one another as capable professionals and value diverse skills.
• Courage: Team members dare to address difficult problems and make appropriate decisions.

These values support how people work within the Scrum framework and complement its accountabilities, events, and artifacts.

Scrum vs Agile: What is the difference?

Scrum and Agile are related but distinct.

Agile is a broader philosophy for project management emphasizing delivering value, responding to change, and learning through feedback.

Scrum is a widely adopted agile framework providing a specific structure for working on complex products through iterative development.

Agile describes a set of values and principles for developing products and responding to change, while Scrum is a specific framework for applying these principles to complex work. Other Agile frameworks and approaches offer different ways to organize and manage work, depending on team needs and project requirements.

The differences become clearer when you understand what Agile methodology is and how it guides teams in adapting to change and delivering value.

Scrum vs Kanban: Choosing the right Agile framework

Scrum and Kanban both support agile project management, but they organize work differently.

Scrum uses defined accountabilities, events, artifacts, and fixed-length Sprints. This structure can work well for teams that benefit from regular planning, review, and reflection.

Kanban focuses on visualizing work, managing work in progress, and improving workflow. It does not require fixed-length Sprints or the same set of Scrum events.

The right choice depends on the work and operating environment of the team. Scrum provides a defined framework for iterative product development, while Kanban can be useful when work needs to flow continuously through a process.
