Kanban vs Scrum: A Product Manager’s Guide to the Differences

What is Kanban?

Kanban is a methodology used for managing and improving the flow of work in a process or system. It was originally developed in the manufacturing industry by Taiichi Ohno at Toyota, but has since been adapted and used in a wide range of industries and processes.

The word “Kanban” comes from Japanese and can be translated to mean “visual signal” or “card”. The Kanban system uses visual signals or cards to represent work items and track their progress through the process.

In a Kanban system, work is pulled through the process by the team, rather than pushed through by a manager or supervisor. This means that work is only started when there is capacity to do it, and new work is only added when capacity is available. This helps to prevent overburdening the team and ensure that work is completed efficiently and effectively.

Kanban also emphasizes continuous improvement through the use of feedback loops and regular review meetings to identify opportunities for improvement and make changes to the process.

What is scrum?

Scrum is a popular framework used for managing and completing complex projects, particularly in the field of software development. It is an agile methodology that emphasizes teamwork, communication, and iterative progress towards well-defined goals.

The Scrum framework includes three main roles: the Product Owner, the Scrum Master, and the Development Team. The Product Owner is responsible for defining and prioritizing the product backlog, which is a list of features or tasks that need to be completed. The Scrum Master is responsible for ensuring that the team adheres to the Scrum framework and resolves any issues that may arise. The Development Team is responsible for completing the work required to deliver the product increment, which is a potentially shippable product increment at the end of each sprint.

The Scrum process is organized into a series of time-boxed iterations called sprints, typically lasting one to four weeks. At the beginning of each sprint, the Development Team selects a set of items from the product backlog to work on, and commits to completing them by the end of the sprint. During the sprint, the team holds daily stand-up meetings to discuss progress and plan the day’s work. At the end of the sprint, the team presents the completed work to the Product Owner and stakeholders at the sprint review, and then holds a sprint retrospective to identify areas for improvement in the next sprint.

Overall, Scrum is designed to be a flexible, collaborative framework that enables teams to deliver high-quality products in a timely and efficient manner.

Difference between Kanban and Scrum

Kanban and Scrum are both popular agile methodologies used in project management to increase productivity, improve efficiency, and reduce waste. However, there are some key differences between the two methodologies.

  1. Focus on Continuous Improvement: Kanban is a continuous improvement methodology that emphasizes delivering value to customers in small increments. On the other hand, Scrum is an iterative and incremental framework that focuses on delivering a potentially shippable product at the end of each sprint.
  2. Roles and Responsibilities: Scrum has clearly defined roles, such as Scrum Master, Product Owner, and Development Team, each with specific responsibilities. In contrast, Kanban does not prescribe specific roles or responsibilities, but rather encourages a collaborative approach where team members work together to get tasks done.
  3. Sprint Planning and Review: Scrum has a defined sprint planning and review process, which occurs at the beginning and end of each sprint. Kanban does not have a set sprint length, and there is no formal sprint planning or review process.
  4. Workflows: Kanban focuses on visualizing the workflow and limiting work in progress (WIP), whereas Scrum emphasizes timeboxed sprints with defined goals and tasks that need to be completed within each sprint.
  5. Change Management: Kanban encourages continuous improvement by allowing changes to the process to be made at any time. Scrum, on the other hand, follows a structured approach and changes to the process are made only during sprint retrospectives.

In summary, Kanban and Scrum are both effective agile methodologies that can help teams improve their processes and deliver value to customers. The choice of which methodology to use will depend on the specific needs of the team and the project at hand.

When to use Kanban and Scrum?

Kanban and Scrum are two popular agile methodologies that are widely used in software development and other industries. Both methodologies aim to improve team efficiency, transparency, and collaboration, but they have different approaches and are better suited for different situations.

Kanban is a lean method that emphasizes visualizing and limiting work in progress (WIP) to improve workflow and reduce waste. Kanban is ideal for teams that have a continuous flow of work and prioritize completing individual tasks as quickly as possible. Kanban is also useful when there is no set timebox for project delivery, and it allows for continuous delivery.

Scrum, on the other hand, is an iterative and incremental approach that emphasizes timeboxed sprints of 1-4 weeks. Scrum is ideal for teams that work on complex projects that require collaboration, planning, and regular feedback. It is also suited to situations where a set timeline for project delivery is important, and it allows for a regular cadence of planning and review.

Ultimately, the choice between Kanban and Scrum depends on the specific needs and constraints of your project and team. Kanban is often used in situations where the work is more continuous and not subject to strict deadlines, while Scrum is better suited to projects with clear goals and deadlines that require a more structured approach. It’s also possible to combine elements of both methodologies to create a customized approach that works best for your team.
