What are Kanban and Scrum?
Kanban is a visual workflow with task flexibility, while Scrum uses structured sprints for focused delivery. Both aim to improve project delivery. Here's a simpler way to explain the difference between the two.
Kanban
Imagine a board with sticky notes listing your tasks. You move them across the board as you work on them, giving you a clear view of progress. It's flexible and lets you add new tasks as needed. Below is a snapshot of what the Kanban board looks like in practice.
Scrum
Think of Scrum as working in sprints. You pick a set of tasks for a short period (like 2 weeks) and focus on completing them before moving on to the next group of tasks. It provides a structured approach with clear deadlines. Below is a snapshot of what the Scrum board looks like in practice.

Kanban vs. Scrum Which should I choose for software development teams
Choosing between Kanban and Scrum for your software development team depends on your project needs and team preferences.
Consider Kanban if
- Your project involves a steady stream of work with frequent changes or new demands.
- Flexibility is paramount, and you need to adjust to shifting priorities.
- Your team excels in a self-organizing environment with minimal bureaucratic overhead.
- Visualizing workflow and tracking task progress is essential.
Consider Scrum if
- Your project has clearly defined objectives and requirements that can be broken into manageable parts.
- Firm deadlines and structured delivery of features are necessary.
- Your team thrives in focused work periods with minimal interruptions.
- Regular collaboration and inspection are vital for project success.
Consider this analogy
- Kanban resembles a swim lane: Tasks flow continuously, and you can add new ones as needed.
- Scrum is like a relay race: You concentrate on completing a set of tasks (the baton) within a sprint (the race leg) before advancing to the next set.
Here's the table with the factors that will help you choose between Scrum and Kanban, along with the suggested choices.
