In the software development world, teams are always on the lookout for methodologies and frameworks that enable them to streamline the process of developing software. Scrum and Kanban are two Agile frameworks that empower teams to optimize the development process and release software quickly and effectively.
Scrum – mainly used for projects – enables development teams to become more Agile and react and respond quickly to sudden changes.
Kanban – mainly used for operations – enables teams to make small, incremental changes efficiently for increased throughput and quality.
If you are looking to leverage these frameworks but don’t know when to use them, read on to find out more!
Scrum is an Agile framework that helps software development teams efficiently work together and deliver business value in the shortest time. It allows teams to rapidly and repeatedly inspect the product at hand and enable them to learn through experience, prioritize tasks, and drive continuous improvement. Since it emphasizes teamwork and iterative development of software, it empowers teams to deliver new software once every 2-4 weeks.
Kanban is an Agile scheduling system that helps software development teams to manage their work efficiently. It allows teams to visualize the entire software development process as well as current tasks passing through that process so that potential bottlenecks can be identified and rectified – in time. Since it provides full transparency, it allows workflows to proceed smoothly and at optimal speed.
Here are the fundamental differences between Scrum and Kanban:
To work on projects in small sprints, integrate feedback, and release software every 2-4 weeks.
To limit work in progress and accelerate time-to-market.
When to use it:
When requirements are rapidly changing, and the team size is large.
When requirements are stable, but the development process needs to be improved, and the team size is small.
Every workflow is represented on a Scrum Board and broken down into manageable chunks or stories. Each story moves from a backlog towards work-in-progress, and finally, completion.
Every workflow is represented on a Kanban board and broken down into manageable chunks. Each chunk needs to be completed in the shortest time possible, so work-in-progress can be limited.
The product owner plans the sprints, prioritizes tasks and communicates with team members. The Scrum Master oversees the process during each sprint. Team members carry out each sprint.
There are no set roles or responsibilities in Kanban; everyone works together as a team.
Scrum places great emphasis on schedule through a prioritized list of story points. Such an iterative approach enables precise estimation of workflow and effective management of multiple projects.
In Kanban, there is no set schedule. Although the framework is iterative, the focus is mainly on continuous improvement.
Changes and iterations:
Most iterations are fixed – and need to be completed within 2-4 weeks; changes cannot be made to pre-existing iterations.
Not based on iterations as the framework focuses on cycle times, changes can be continually added.
Key metrics to track:
The entire team focuses on collaboration so that tasks can meet quality and schedule requirements.
The entire team focuses on collaboration, so tasks on Kanban boards can be completed quickly.
Now that you’ve got an idea of the fundamental differences between Scrum and Kanban, you should be able to implement the frameworks in the right manner.
However, if you’re still confused about where you can use Scrum and where you can use Kanban, let’s take some examples:
In the software development world, the evolution of Agile has become unstoppable. As teams look to adopt frameworks that drive productivity, Scrum and Kanban are the two most clear and compelling choices. While Scrum allows teams to break tasks into small manageable chunks, Kanban helps them visualize the entire process so that work can be completed faster.
Given the many benefits of both, it makes sense to use them both to streamline the development process, improve development efficiency, and accelerate time to market.
