Kanban Vs. Scrum: Understanding Agile Frameworks for Effective Project Management
Agile methodology has transformed project management, focusing on flexibility, collaboration, and continuous improvement. Among its most popular frameworks are Kanban and Scrum, both designed to help teams manage workflows efficiently. Though they share common Agile principles, their approaches to organization, workflow, and roles differ significantly. Understanding these differences is crucial for choosing the right approach that aligns with your team's goals. This blog post explores Kanban and Scrum, their key elements, and how to choose the best one for your projects.
Understanding Kanban
What is Kanban?
Kanban is a visual workflow management method that originated in manufacturing and has since been adapted for software development and other industries. Its core goal is to ensure a steady flow of work, with an emphasis on visualizing tasks, limiting work in progress (WIP), and promoting continuous delivery.
Key Principles of Kanban
- Visual Workflow Kanban uses a visual board, typically divided into columns such as "To Do", "In Progress", and "Done". This makes it easy to track progress, spot bottlenecks, and ensure that no task is neglected.
- Continuous Delivery Unlike time-boxed frameworks, Kanban emphasizes the steady delivery of work. Tasks move through the workflow at their own pace, and updates are delivered as soon as they’re ready.
- Limiting Work in Progress (WIP) By restricting the number of tasks allowed in each column at any given time, Kanban helps teams avoid overburdening themselves, ensuring focus and reducing cycle times.
Benefits of Using Kanban
- Flexibility: Kanban allows teams to adjust their processes quickly without being tied to specific time frames or roles.
- Efficiency: By visualizing workflows and limiting WIP, teams can identify bottlenecks, improve focus, and increase overall efficiency.
Understanding Scrum
What is Scrum?
Scrum is a structured, time-boxed Agile framework used for managing complex projects. It breaks work into Sprints - typically 1 to 4 weeks long - during which teams aim to deliver a product increment. Scrum includes defined roles, regular events, and specific artifacts to guide the team throughout the process.
Key Elements of Scrum
-
Roles
- Scrum Master: Facilitates the Scrum process, removes impediments, and ensures the team adheres to Scrum principles.
- Product Owner: Manages the product backlog, prioritizes tasks, and ensures the team works on the most valuable items.
- Development Team: A self-organizing, cross-functional group responsible for delivering the product increment within each Sprint.
-
Events
- Sprints: Fixed-length periods where the team completes a set of tasks to deliver a product increment.
- Daily Standups: A brief daily meeting where team members share updates, challenges, and plans for the day.
- Sprint Demo: Held at the end of each Sprint, where the team presents the completed work to stakeholders for feedback.
- Sprint Retrospective: A meeting held after each Sprint to reflect on the process and identify improvements.
-
Artifacts
- Product Backlog: A prioritized list of tasks and features to be completed, managed by the Product Owner.
- Sprint Backlog: A subset of the Product Backlog, containing tasks to be completed in the current Sprint.
- Feature or Increment: The working product or feature that is completed at the end of each Sprint.
Benefits of Using Scrum
- Focused Teamwork: Scrum’s structure encourages collaboration within a team, ensuring everyone knows their roles and responsibilities.
- Regular Feedback: With Sprint Demos and Retrospectives, Scrum enables regular feedback from stakeholders and continual process improvements.
Key Differences Between Kanban and Scrum
- Structure vs. Flexibility
- Kanban: Highly flexible, without predefined roles or time-boxed iterations. Teams can adjust to changes easily, making it ideal for fluctuating workloads.
- Scrum: Structured with specific roles, events, and timelines. Scrum is best for teams that need clear planning, defined roles, and regular cycles of delivery.
- Work Iteration vs. Continuous Flow
- Kanban: Emphasizes continuous flow, with work moving through the system as soon as capacity allows. There are no fixed iterations, making it ideal for ongoing, ad-hoc work.
- Scrum: Uses Sprints, where work is completed within a fixed time-frame, typically 1-4 weeks. This approach is well-suited for teams with a clear set of tasks and deadlines.
- Roles and Responsibilities
- Kanban: No specific roles are required beyond the team members themselves. The focus is on managing workflow and ensuring smooth operations.
- Scrum: Clearly defined roles (Scrum Master, Product Owner, Development Team) with specific responsibilities to maintain structure and accountability.
Choosing the Right Framework
When deciding between Kanban and Scrum, several factors should guide your choice, such as team size, project type, and the desired outcome.
Factors to Consider
- Team Size
- Kanban is well-suited for smaller teams or teams with a fluctuating volume of work. Its flexibility is beneficial for teams that need to adjust quickly.
- Scrum works best for medium to large teams that require structured collaboration and defined roles.
- Project Type
- Kanban is ideal for support, maintenance, or ongoing work that doesn’t follow a strict timeline. It's also great for teams dealing with customer requests or operations.
- Scrum is suited for complex, project-based work, particularly when you need clear, iterative progress and regular feedback.
- Desired Outcomes
- Kanban is perfect if the goal is to improve efficiency by continuously delivering work without fixed iterations.
- Scrum is better when you want to focus on delivering a product increment at the end of each Sprint, with a focus on regular feedback and team improvements.
When to Use Kanban
- For teams that handle ad-hoc tasks or work that doesn’t fit neatly into time-boxed Sprints.
- When the workflow needs to be adjusted frequently or requires flexibility to accommodate incoming requests.
- If your primary goal is to optimize the flow of work and eliminate bottlenecks.
When to Use Scrum
- When working on a product that requires structured development, with clear roles and deadlines.
- When regular feedback from stakeholders is necessary to refine the product.
- When your team benefits from iterative cycles that provide regular opportunities to reflect and improve.
At Fishtank Consulting we use Kanban or Scrum in DevOps after we carefully discuss and understand our clients’ needs. See below 2 examples of Kanban and Scrum boards.

Kanban Vs. Scrum: Finding the Perfect Agile Fit for Your Team's Success
Kanban and Scrum are both highly effective Agile frameworks, but they differ in structure, flexibility, and approach to work. Kanban offers a flexible, continuous flow of tasks, making it ideal for teams that need to adapt to changing demands or handle ongoing work. Scrum, with its structured Sprints and defined roles, is better suited for teams working on complex projects that benefit from clear planning and regular feedback.
Choosing the right framework depends on your client’s needs and type of project, your team’s size, and the outcomes you want to achieve. By mastering the principles of both Kanban and Scrum, you can unlock the full potential of your team and achieve Agile success. Whether you’re aiming for flexibility or structure, the key to success lies in aligning the right methodology with your client’s unique needs and goals.
