Kanban vs. Scrum: Which Agile Methodology Is Right for Your Project?

Choosing between Kanban and Scrum often comes down to your project's specific needs: Kanban is ideal for continuous, evolving workflows, while Scrum provides structure for complex projects with fixed deadlines. This comparison is based on industry-standard definitions from the Project Management Institute (PMI) to help you decide.

What is the core difference between Kanban and Scrum?

While both are agile methodologies—a project management style emphasizing iterative progress and team collaboration—their core philosophies differ. Kanban is a visual workflow management tool designed for continuous delivery. It focuses on visualizing work on a Kanban board and limiting Work-in-Progress (WIP) to improve flow. In contrast, Scrum is a sprint-based framework that structures work into short, fixed-length cycles called sprints, typically lasting one to four weeks, to deliver a potentially shippable product increment.

The table below summarizes the fundamental differences at a glance:

How do the roles and practices compare?

Scrum relies on a well-defined set of roles and ceremonies. The Scrum Master serves as a facilitator, the Product Owner manages the backlog and defines priorities, and the Developers are responsible for delivering the work. Their process includes sprint planning, daily stand-ups, and a sprint retrospective.

Kanban, however, is more flexible. There are no mandatory roles; the team collectively manages the flow of work. Practices center on the Kanban board, which visually tracks tasks through columns like "To Do," "In Progress," and "Done." A key practice is setting WIP limits for each column to prevent bottlenecks and ensure a smooth workflow.

Which methodology should you choose for your team?

Based on our assessment experience, the best choice depends on your project's nature and your team's goals.

Choose Kanban if:

• You manage an ongoing service or maintenance project with frequently changing priorities.
• Your primary goal is to improve delivery speed and reduce the time it takes to complete tasks (cycle time).
• Your team benefits from a visual system and needs the flexibility to introduce new tasks as soon as capacity is available.

Choose Scrum if:

• You are developing a new product or a complex project with a clear end goal and specific deadlines.
• Your team thrives with structured intervals and fixed deadlines to drive progress.
• The project benefits from regular, scheduled feedback loops after each sprint to adapt the product.

In practice, many teams adopt a hybrid approach, often called "Scrumban," to leverage the structure of Scrum with the flow-based flexibility of Kanban.

Ultimately, the most effective framework is the one that aligns with your team's workflow and project objectives. Evaluate your project's need for structure versus flexibility and consider starting with a trial period to assess which methodology yields better results for your specific context.
