What Is A Scrum: Comprehensive Guide And Benefits

What Is A Scrum? It’s a simple framework for complex projects. At WHAT.EDU.VN, we’re dedicated to providing clear, concise answers to your questions. Discover how this versatile approach can revolutionize teamwork and project management with agile methodology and iterative development. Let’s explore the scrum process and scrum values.

1. Understanding What a Scrum Is

Scrum is an agile framework used to manage and control complex projects. It focuses on iterative progress, team collaboration, and delivering working software frequently. Unlike traditional project management methods, Scrum embraces change and continuous improvement. This approach enables teams to respond quickly to evolving requirements and deliver value incrementally.

Key Concept: Scrum is a lightweight framework that helps teams work together.
Focus: Iterative development, team collaboration, and adaptability.
Advantage: Faster response to change and continuous value delivery.

1.1 Origins and History of Scrum

The term “Scrum” was first introduced in a 1986 paper by Hirotaka Takeuchi and Ikujiro Nonaka, “The New New Product Development Game.” They likened the process of high-performing teams to the scrum formation in rugby, where the entire team works together to move the ball forward.

1986: Takeuchi and Nonaka’s paper introduces the concept.
Early 1990s: Ken Schwaber and Jeff Sutherland independently develop Scrum.
1995: Schwaber and Sutherland formally present Scrum at OOPSLA ’95.
2001: The Agile Manifesto is created, influencing Scrum’s adoption.
Today: Scrum is widely used across various industries for project management.

1.2 Scrum vs. Traditional Project Management

Scrum differs significantly from traditional project management methodologies like Waterfall. Waterfall follows a linear, sequential approach, with each phase completed before moving to the next. Scrum, on the other hand, is iterative and incremental.

Feature	Scrum	Waterfall
Approach	Iterative and incremental	Sequential and linear
Flexibility	High; accommodates changes frequently	Low; difficult to adapt to changes
Team Structure	Self-organizing, cross-functional teams	Hierarchical, specialized roles
Customer Involvement	Continuous involvement and feedback	Limited involvement, primarily at start and end
Delivery	Frequent delivery of working software	Single delivery at the end
Risk Management	Risks are identified and addressed iteratively	Risks are addressed primarily at the start

1.3 Core Principles of Scrum

Scrum is built on several core principles that guide its implementation and ensure its effectiveness. These principles include transparency, inspection, adaptation, self-management, and focus on value.

Transparency: All aspects of the process are visible to everyone on the team. This includes the progress, impediments, and decisions made.
Inspection: The Scrum Team regularly inspects the product and process to detect undesirable variances.
Adaptation: Adjustments are made based on the inspection results to minimize deviations and ensure continuous improvement.
Self-Management: Teams decide how best to accomplish their work, rather than being directed by others.
Focus on Value: Delivering maximum business value is the primary goal of the Scrum Team.

3. Scrum Events: A Step-by-Step Guide

Scrum defines five key events that provide a structured framework for the Scrum Team to work together. These events are time-boxed, meaning they have a maximum duration to ensure efficiency and focus.

3.1 The Sprint

The Sprint is the heart of Scrum. It is a time-boxed period, typically two to four weeks long, during which the Scrum Team works to complete a set of tasks and create an Increment of the product.

Key Characteristics of a Sprint:
- Time-boxed: Sprints have a fixed duration.
- Consistent Duration: The length of a Sprint remains consistent throughout the project.
- Goal-Oriented: Each Sprint has a specific goal that aligns with the overall product vision.
- Focus on Value: The team focuses on delivering the highest value items from the Product Backlog.
- No Changes: Once the Sprint begins, the Sprint Goal should remain stable.

3.2 Sprint Planning

Sprint Planning is an event where the entire Scrum Team comes together to plan the work for the Sprint. The team discusses the Sprint Goal and selects items from the Product Backlog to include in the Sprint Backlog.

Key Activities During Sprint Planning:
- Defining the Sprint Goal: The team collaborates to define a clear and achievable Sprint Goal.
- Selecting Items from the Product Backlog: The team selects user stories, features, and tasks from the Product Backlog that align with the Sprint Goal.
- Creating the Sprint Backlog: The selected items are added to the Sprint Backlog, which is a detailed plan for the Sprint.
- Estimating Effort: The team estimates the effort required to complete each item in the Sprint Backlog.
- Identifying Tasks: The team breaks down each item into smaller, manageable tasks.

3.3 Daily Scrum

The Daily Scrum is a 15-minute time-boxed event for the Developers. It is held at the same time and place each day to ensure consistency and efficiency.

Purpose of the Daily Scrum:
- Synchronize Activities: The Developers synchronize their activities and create a plan for the next 24 hours.
- Identify Impediments: The team identifies any obstacles that are preventing them from achieving the Sprint Goal.
- Promote Communication: The Daily Scrum promotes communication and collaboration among the Developers.
- Inspect Progress: The team inspects the progress toward the Sprint Goal.
Typical Questions Asked During the Daily Scrum:
1. What did I do yesterday that helped the Development Team meet the Sprint Goal?
2. What will I do today to help the Development Team meet the Sprint Goal?
3. Do I see any impediment that prevents me or the Development Team from meeting the Sprint Goal?

3.4 Sprint Review

The Sprint Review is an event held at the end of the Sprint to inspect the Increment and adapt the Product Backlog if needed. The Scrum Team and stakeholders collaborate to review the work that was completed during the Sprint.

Key Activities During the Sprint Review:

Typical Questions Asked During the Sprint Retrospective:
1. What went well during the Sprint?
2. What could have been better?
3. What actions can we take to improve in the next Sprint?

4. Scrum Artifacts: The Building Blocks of Scrum

Scrum artifacts represent work or value. They are designed to maximize transparency of key information so everyone has the same understanding of the product, the work being done, and the overall progress.

4.1 The Product Backlog

The Product Backlog is an ordered list of everything that might be needed in the product. It is the single source of requirements for any changes to be made to the product.

Key Characteristics of the Product Backlog:
- Ordered: Items in the Product Backlog are ordered based on their value, risk, and dependencies.
- Emergent: The Product Backlog is a living document that evolves as the product evolves.
- Detailed: Items in the Product Backlog are refined and detailed as they move closer to implementation.
- Visible: The Product Backlog is visible to everyone on the team.
- Managed by the Product Owner: The Product Owner is responsible for managing and maintaining the Product Backlog.

4.2 The Sprint Backlog

The Sprint Backlog is a plan by the Developers for realizing the Sprint Goal. It is a forecast by the Developers about what functionality will be in the next Increment and the work needed to deliver that Increment.

Key Characteristics of the Sprint Backlog:
- Owned by the Developers: The Developers own and manage the Sprint Backlog.
- Detailed: The Sprint Backlog contains detailed tasks and activities needed to complete the Sprint.
- Flexible: The Sprint Backlog can be updated and refined throughout the Sprint as needed.
