Both Scrum and Kanban belongs to the same methodology i.e. Agile. Though both these terms have subtle differences between them, the principles are the same, meaning both will help to build better products and services.

Also, there is this one thing that they have in common, that is, both are known as pull systems. This pull system makes sure that the work gets from the product backlog to customers in the shortest period time. But both the scrum and the Kanban implement the pull system in two different ways.

So we at takethiscourse.net have managed to gather out many differences between Scrum and Kanban which are mentioned below.

Scrum

Kanban

Scrum is known to be an agile framework that enables us to put all our efforts into delivering the business value in an appropriate manner and in as little time as possible.Whereas, Kanban is a visual system that is used for managing all the software development work. This method nurtures continuous improvement, efficiency and it is highly likely that the productivity ratio increases using Kanban.
Scrum is typically or more concerned with the continuous process improvements.Kanban is quite concerned with getting more work done and in a shorter time.
Scrum has quite a pre-defined structured framework.Contrary, Kanban is less structured and it is based on a list of items to do.
Scrum defined three roles:
1. Product Owner who interact with stakeholders and maintain product backlog.
2. Development Team has a flat structure and work in sprints.
3. Scrum Master who ensures the scrum practices to be implemented and removes the impediments (if any).
Whereas, in Kanban, there are no pre-defined roles assigned to the team members.
In scrum, the deliverables are determined through Sprints. Sprint is a period of time that is set and a particular work has to be done in that set time.In Kanban, all the products and processes are completed and delivered continuously on a need base scheme. But the due dates are decided by the business as needed.
Pull system is used in the scrum. During a Sprint planning meeting, items from Product Backlog are pulled for a sprint known as Sprint Backlog.On the other hand, the pull system is also used in Kanban which allows the team members to only pull new tasks when the previous task is completed by the team. Depending on the team size, the number of tasks pulled may vary.
While using scrum, even if a very high priority requirement comes, it will be taken to Product Backlog and pulled in next sprint. No new items are pulled once the sprint started.On the other hand, as there is no concept of Sprint in a Kanban approach, so such high priority tasks can be pulled from the backlog.
The scrum methodology is best for those teams that have stable priorities. Meaning, they don’t need to make changes in the middle of the project.This methodology is best for those projects that have widely-varying priorities.
Scrum measures productivity using velocity with the help of sprints. As sprints occur in sequence and number of story points delivered in each sprint help to find out the team velocity for upcoming work.The Kanban measures productivity using cycle time or maybe the amount of time that is required to complete one full project piece from start to end.

By looking at the differences from the above table, any learner can easily understand the differences that scrum and Kanban have among them. But all differences aside, one thing every learner must remember is that both these approaches/frameworks work on the same principle that helps different teams to abide by agile principles and get projects done.

So whatever the methodology you choose, just make sure that you are clear on the principles.
