Scrum VS Kanban

ScrumKanban
Scrum stresses on planning.
It starts with sprint planning and ends up with sprint retrospective.
There are many meetings held which help to assure that the team is aligned with the next steps, priorities, and learnings from previous sprints.
Kanban is open to making changes on the go. It means there is less rigidity and things can change frequently.
It recommends collection of time measurements made during sprints.Kanban recommends graphs to get an overview of team's progress over time.
Scrum no longer asks for a commitment from teams. Instead, it is about the sprint goals and forecasts.Kanban relies on time-boxing and forecasts.
It stresses on planning, and so estimation has a very important role in ScrumKanban has no mandatory requirements for estimation.
Every individual has their role and responsibilities.No set roles so flexibility in term of individual responsibilities.
The iterations/Sprints are fixed in duration.
This duration varies from 2 weeks to 1 month.
Kanban is not based on duration. This thing is measured regarding Cycle times.
Teams are required to commit a specific amount of work.Commitment not necessary it is optional for teams
In this method, cross-functional teams are important as they can deal with any disruption that may cause a bottleneck in the software development.Having specialized team is important.
It is not possible to add items to ongoing iterations.New items can easily add if the additional capacity is available.
A sprint backlog is owned by only by a single team.Multiple teams can share Kanban board.
Deliverables are determined by sprints, which a set of work must be completed and ready for review.Products and processes are delivered continuously on a needed basis. So testing and review process goes on simultaneously.
Scrum software development method focuses on the backlog.Kanban method entirely focuses on process dashboard.
Every team member has a specific role in Scrum master decide timelines, product owner set goals and objectives, and team members conduct the development work.There are no pre-defined roles for a team. However, there may still be a Project Manager; the team is encouraged to collaborate and works together.
Best for projects with changing priorities.Ideal for teams with stable priorities that unlikely to change over time.
Measures production using velocity through sprints.Measures production using cycle time or the exact time it takes to complete one full piece of a project.
Scrum requires a complete shift from the traditional model to the Agile Scrum model that would be implemented the project.Kanban doesn't allow drastic changes in the project.
It is an ideal method for projects with widely-varying priorities.Best suitable for teams with stable priorities.
In Scrum, the entire team focuses on to collaborate and complete the task to provide quality development work.Teams work to achieve goals and reduce the time to complete the entire process. Thus, reduction in the time cycle is biggest indicators of success here.
Scrum emphasis on its schedules; new items cannot be added to ongoing iterations.Kanban is more iterative by nature as it does not have specific timeframes. So that, new items can be continually added whenever additional capacity is available.
The total work is done in batches/Sprints.The entire project is performed on the movement of single-threaded work item flows.
Scrum master acts as a problem solver.Kanban encourages every team member is a leader and sharing responsibility amongst them all.
Scrum prescribes time-boxed iterations.Kanban focuses on planning a different duration for individual iteration.
Scrum helps firms to save time and money.Kanban method focus on continuous improvement, productivity, and efficiency.
Achieve stable and consistent communication of performance at all levels.Team members are more likely to accomplish their goals much easier because of visual nature of Kanban boards.
Project are coded and tested during the sprint reviewTeam members are more likely to accomplish their goals much easier because of visual nature of Kanban boards.
It is easier to adapt to the constant changes because of the short sprints and regular feedback.It is designed for a regular, steady output, major changes in customer demand can make Kanban fail.
The total cost of the project is minimal which may lead to quicker and cheaper result.If a task is not correctly estimated, the total project cost will never be accurate. In such cases, the task can be spread over several sprints.
This methodology requires experienced team members only. So, If the team consists of people who are not an expert, the project cannot be completed in time.No specific timeframes are allocated with each phase, so team members never get the idea how much time they can take in every phase.
In this Agile Scrum method, it is easier to deliver a quality product at a scheduled time.It is designed for a regular, steady output, major changes in customer demand can make Kanban fall.
The project plan will never disturb even if a team member leaves the team.If any of the team members exit during development, it can hurt the project development.
Daily meetings sometimes frustrate team members.Outdated Kanban board can lead to issues in the development process.
Large projects can easily divided into easily manageable sprints.Only works well with small teams so not suitable large size team.
