Scrum vs Agile Methodology: What’s the Difference?
Terms like Agile and Scrum often come up in software development. While these two are interconnected, they are not the same thing. Many organizations strive to be “Agile” or use “Scrum,” but what do these terms really mean?
In this article, we’ll explore the differences between Agile and Scrum, explaining how they’re connected, and which one might be right for your team.
What is Agile Methodology?
Agile is a project management approach that prioritizes adaptability, teamwork, and ongoing enhancement. Established in 2001 with the creation of the Agile Manifesto, Agile was a reaction to the rigid structure of traditional project management models, particularly the waterfall model, which was linear and often restrictive.
What is Scrum?
Scrum provides a structured framework within Agile that boosts collaboration, accountability, and progressive development through iterative cycles. Created as a practical application of Agile values, Scrum organizes work into “sprints,” which are short cycles (usually 2-4 weeks) focused on completing specific project segments.
Differences Between Agile and Scrum
While Agile is a general philosophy, Scrum is a more rigid framework. Here’s a closer look at the differences:
| Aspect | Agile | Scrum |
| Iterative Approach | Agile teams perform multiple iterations organized into a prioritized backlog, based on user feedback. | Scrum breaks projects into smaller segments known as sprints, each with specific goals and backlogs. |
| Project Flexibility | Agile supports flexibility, allowing adjustments throughout the project. | Scrum is more structured and rigid, ideal for teams focused on delivering results rapidly. |
| Software Delivery Frequency | Agile enables regular software deliveries for feedback, supporting continuous development and testing. | Scrum delivers functional software after the completion of each sprint. |
| Suitable Team Size | Agile fits well with smaller teams that favor simplicity in both design and execution. | Scrum is often better suited for creative and experimental teams. |
| Relationship | Agile serves as an overarching philosophy that includes various methodologies focused on software delivery. | Scrum is a specific methodology within Agile, designed to manage projects effectively. |
| Comparison to Kanban | Agile and Scrum share similarities with Kanban, another Agile-based framework widely used in marketing. | Scrum defines specific roles for team members, while Kanban promotes a collaborative approach. |

Which Should You Choose: Agile or Scrum?
Selecting between Agile and Scrum depends on the nature of your project. Agile is preferable for environments needing high adaptability, while Scrum is suited for teams benefiting from a clear, repetitive process.
Common Misconceptions about Agile and Scrum
- Agile and Scrum are the same thing.”
While Scrum is a framework within Agile, Agile is a broader philosophy encompassing various approaches, including Scrum, Kanban, and Lean. Agile is the mindset, whereas Scrum is a specific method for applying Agile principles. - “Agile means no planning or structure.”
Agile emphasizes adaptability, but it doesn’t mean avoiding planning. Agile teams plan in shorter cycles, allowing flexibility, but they still follow structured processes to manage tasks, timelines, and goals effectively. - “Scrum is only for software development.”
Although widely used in software, Scrum can apply to other fields like marketing, education, and research. Its principles of iteration, collaboration, and structured roles can benefit a variety of industries. - “Agile and Scrum don’t require documentation.”
Agile prioritizes delivering functional software rather than exhaustive documentation, though it doesn’t discard documentation entirely. Scrum teams document as needed, prioritizing clarity and keeping essential information available to support team alignment and quality. - “Scrum works for all projects.”
Scrum is powerful, but it may not suit every project, especially those requiring continuous flexibility or undefined roles. Projects needing high adaptability or those without strict timelines may benefit more from other Agile approaches like Kanban. - “Agile and Scrum lack accountability.”
Both Agile and Scrum require strong accountability within teams. Scrum, for instance, has defined roles (Product Owner, Scrum Master, and Development Team) to ensure responsibility is clear and goals are met. - “Agile sacrifices quality for speed.”
Agile focuses on delivering small, workable components quickly, but it does not compromise on quality. Continuous testing and feedback loops uphold quality standards, embedding quality assurance into every release cycle.

Best Practices for Implementing Agile and Scrum
To make Agile or Scrum successful:
- Prioritize Customer Input: Actively seek feedback from stakeholders and users following each iteration, incorporating their insights into development. This practice ensures that your project stays aligned with user needs, helping to build a product that genuinely serves its intended purpose.
- Hold Regular Retrospectives: At the close of each sprint or iteration, hold a retrospective session to assess successes and pinpoint improvement areas. These retrospectives are integral to Agile and Scrum, promoting continuous learning and refining processes.
- Define Clear Roles and Responsibilities: Ensure that everyone on the team understands their roles, especially in Scrum, where roles like Product Owner, Scrum Master, and Development Team are defined. Clear roles streamline the process and keep everyone focused on their responsibilities.
- Limit Work in Progress (WIP): Keep the team’s focus on a few high-priority tasks at a time. Limiting WIP prevents task overload, maintaining quality, reducing bottlenecks, and enhancing team productivity.
- Use Visual Tools for Tracking Progress: Visual tools such as Kanban boards, burndown charts, or dashboards provide clear task visibility. They help track progress and quickly identify bottlenecks, allowing the team to respond swiftly to any challenges.
- Maintain a User-Centric Approach: Keep the end-user at the forefront of each sprint or iteration. This user-focused perspective ensures that every update adds real value, aligning the project more closely with the needs and expectations of those who will use it.
- Stay Flexible and Open to Change: Agile and Scrum both emphasize adaptability. Remain open to modifying your approach based on feedback or new requirements, fostering a flexible environment that supports continuous improvement.
Conclusion
Both Agile and Scrum have revolutionized project management, each catering to different needs. Agile’s adaptability suits fast-paced, dynamic projects, while Scrum offers a disciplined approach ideal for projects requiring structured cycles. By understanding the unique strengths of each, teams can choose the right path to deliver effective results.
