In previous publications we analyzed in depth these two methodologies that are usually applied in environments where efficiency and speed are key to success. Although both Kanban and Scrum share fundamental principles, within agile methodologies they offer different ways to manage projects.
In this article, we analyze in detail the differences between these two methods, evaluating their advantages, disadvantages and scenarios in which each one shines and adapts better to the needs of your team or project, thus maximizing your efficiency and results.
How Kanban works
With this method, a visual representation of tasks or work units is used to improve understanding of the production flow through a board, which organizes the work into columns, where each column represents a phase or status of the process such as “pending”, “in process” and “completed”.
Often, Kanban boards also use swimlanes, horizontal lines that group types of work or different teams, which adds another layer of organization and clarity to the workflow.
The main objective of Kanban is to visualize the workflow and thus be able to identify bottlenecks, limit work-in-progress (WIP) and maximize system efficiency using principles such as Kaizen (continuous improvement) and JIT (Just-In-Time). In this way, tasks are managed so that they are completed just when they are needed, ensuring that teams are not overloaded and incomplete tasks do not accumulate.
Advantages of Kanban
- Flexibility: It does not require a fixed time frame, which means that tasks can be added at any time.
- Ease of implementation: Teams can start using Kanban without making major organizational changes.
- Visual approach: The Kanban board provides a clear view of the status of each task, making it easy to detect bottlenecks.
Disadvantages of Kanban
- Lack of predefined structure: Being more flexible, it may not provide the structure that some teams need to follow a consistent rhythm.
- Less focus on specific roles: Kanban does not define team roles like Scrum, which can make it difficult to clearly assign responsibilities in some contexts.
How Scrum works
Scrum is an agile framework that relies on principles such as empiricism, self-organization and transparency to facilitate efficient and flexible product development.
Empiricism allows teams to learn from experience and make evidence-based decisions, while incremental iterations, called Sprints, organize work in short cycles that result in frequent deliverables of value.
Teams in Scrum are self-organized, which gives them autonomy to decide how to do their work and adapt quickly to changes. On the other hand, transparency ensures that everyone involved has visibility into the status of the project, facilitating collaboration and decision making.
In addition, Scrum relies on constant inspection and adaptation to adjust the process and improve product quality. The roles in Scrum are clearly defined: the Product Owner maximizes the value of the product by managing the Product Backlog, the Scrum Master facilitates the process and removes obstacles, and the development team, which is cross-functional and autonomous, is in charge of product creation.
Advantages of Scrum
- Defined structure: Clear iterations and roles provide a solid structure for teams that need guidance.
- Focus on value delivery: Working in sprints, teams are required to deliver a functional product in each cycle, which ensures a constant focus on value delivery.
- Clear responsibilities: Defined roles in Scrum ensure that all team members understand their role, which helps coordinate the effort.
Disadvantages of Scrum
- Stiffness in sprints: The fixed sprint structure may not be suitable for projects where priorities change frequently.
- Requires discipline: For Scrum to work well, teams need to be disciplined in implementing events and adhering to the framework rules.
- Initial complexity: For teams unfamiliar with Scrum, implementation may require more time for adaptation and training.
Comparison Kanban vs Scrum
| Kanban | Scrum | |
| Flexibility | High: Continuous workflow. | Low: Fixed iterations (sprints). |
| Time structure | Flow without fixed deadlines. | Fixed-time sprints. |
| Defined roles | No formal roles. | Clearly defined roles. |
| Planning | Demand-driven. | Planning at the start of the sprint. |
| Priority changes | Allows changes at any time. | Changes only between sprints. |
Which methodology to choose?
Kanban is ideal for teams that manage a constant workflow, such as those handling technical support, maintenance or environments where priorities change frequently. Therefore, if the project does not need the rigid structure of sprints and a visual workflow management is preferred, this method is the best option. Also, if the team already has an established methodology and is looking to make incremental improvements, Kanban can be implemented gradually without major changes.
On the other hand, Scrum is more suitable for teams working on complex projects with clear deliverables, such as in software development, so it is ideal if you need a more defined structure and a focus on delivering value at regular intervals. If you work in environments where roles and responsibilities need to be clearly established, and where the team will benefit from iterative planning and regular retrospectives, the Scrum methodology works perfectly.
Conclusion
Kanban and Scrum both offer agile approaches to project management, but are different in their philosophy and application. While Kanban is more flexible and focuses on continuous workflow optimization, Scrum provides a more formal structure with short iterations and regular deliverables of value. For this reason, the decision between Kanban and Scrum will depend on the specific needs of the project, the nature of the work to be handled by the team and the environment in which it operates.
So if the project requires flexibility and a focus on continuous improvement, Kanban may be the best option, but if more structure, defined roles and an iterative approach to product delivery are needed, Scrum may be the more effective solution.
