Kanban vs Scrum

There are many differences between Kanban and Scrum. A list of differences between Kanban and Scrum are given below:

	Scrum	Kanban
Planning	It has fixed planning. It focussed on planning. It starts with the sprint planning and ends with the sprint review, retrospective. The daily meeting is held so that the team knows the next steps, priorities, and the learnings from the previous steps.	It has no fixed planning, and no daily meetings are conducted. In Kanban, changes can occur at any time, i.e., frequent changes occur.
Timeline	In scrum, we work on the sprint that has the fixed-time duration means that after some fixed-time, we are delivering something to the client.	Kanban does not have the concept of a sprint, so it has no fixed timeline for delivering the product to the client.
Task estimates	During sprint planning, it is decided that how many activities are to be pulled from the product backlog and add in a sprint backlog. For example, if the sprint is for two weeks, then the number of activities are selected in such a way that they can be completed within the sprint, i.e., in two weeks.	It does not estimate the task.
Scrum Master	In scrum methodology, we have one scrum master who handles the team and conducts the meeting on a daily basis.	In Kanban methodology, we do not have any scrum master. It's the responsibility of each individual to deliver a valuable product.
Suitability	This methodology is suitable for large-sized projects as large-sized projects can be divided into multiple sprints.	It is mainly suitable for small-sized projects.
Constant changes	In Scrum, constant changes can be adapted easily in shorter sprints.	If any major change occurs, then Kanban methodology gets failed.
Cost	In Scrum, the task is estimated, i.e., a fixed number of activities are taken in a sprint, so the total cost of the project is minimal.	In Kanban, the task is not estimated, so the total cost of the project is not accurate.
Roles and responsibilities	In Scrum, a specific role is assigned to the team members by the Scrum Master while the product owner tells the objectives of the product on which team members have to work.	No predefined role is assigned to the team members. It's the responsibility of all the team members to work in collaboration to deliver a valuable product.
Measurement of Productivity	The productivity is measured by using cycle time or the time taken to complete the whole project from start to the end.	Productivity is measured by using velocity through sprints.
Release Methodology	Small release after the end of each sprint.	It provides continuous delivery.
