Difference between Scrum and Kanban | Vietnam Offshore Development Service
Scrum and Kanban are two words that are often used interchangeably and are misunderstood as synonyms. In fact, the two methods, Scrum and Kanban, are different and are often combined with Scrum Van. Understanding the differences between the two methods will help you choose the method that works best for your company. Therefore, Hachinet will help you to comprehend well.
1. What is Kanban?
Kanban is a term that began with the development of Toyota Motor Corporation. Toyota Motor Corporation is an intelligent company management system that contributes to the development of the Japanese economy and is the management standard for large-scale manufacturing industries in Japan.
Kanban means billboard or signboard in Japanese. It can be divided into four basic principles.
1.1 Visualize project planning
Kanban is a tool for visualizing project plans. The Kanban board contains columns suitable for the work situation, and you can use a physical board such as Trello or Kanban support software.
1.2 Limit Work In Progress (Limit WIP – Limit Work In Progress)
It is necessary to limit the amount of work that can be done at the same time.
This principle helps reduce the amount of work in the "nearly completed" state during the process, thereby shortening the time each work passes through the Kanban system. In addition, ongoing work restriction principles help teams focus on their work. You don't have to waste time switching between different tasks.
1.3 Focus on workflow
You can optimize your Kanban system by implementing ongoing work restriction principles and developing policies for your team. Manage and improve your flow to reduce lead times and make your flow smoother.
1.4 Continuous improvement
The team measures efficiency by checking the leads and mass of the product. From there, Kanban will analyze, experiment, and modify the system to improve the efficiency of the team.
2. What is Scrum?
Scrum is one of the agile development methods. Scrum is built on empirical process control and is also known as "Empiricism". The theory states that knowledge comes from experience and decision-making is based on what is known. This helps mitigate risk and increase accuracy, especially in unstable software development environments.
The simplest example of the Scrum concept is a flock of migratory birds. Flocks of migratory birds do not have a blueprint on their journey, but they can move to unfamiliar areas by continuously observing and adapting to the climatic conditions of each region.
In Scrum, the realization of empirical process control relies on three main ideas: transparency, inspection, and adaptation.
Transparency ensures that aspects of the process that affect the outcome are visible to the people who manage the outcome. Transparency requires that its elements be defined based on criteria. They help the observer know what is being seen.
Scrum users should inspect various aspects of the process sufficiently often to detect unacceptable fluctuations within the process. The frequency of inspections is changed by the act of inspection so that it does not affect the business. Examinations are most useful when performed by a skilled person at an important point in the work.
If the inspection results in one or more aspects of the process being unacceptable and the inspector determines that the resulting product is unacceptable, the inspector will need to adjust the material ((processed material)). Adjustments should be made as quickly as possible to minimize further deviations.
We need to ensure that all three major ideas are unified as a whole.
3. Comparison of Scrum and Kanban
"Scrum" and "Kanban" are rooted in the same idealism. However, the realization of the two methods is different.
3.1 Similarities between Scrum and Kanban
- Both the Scrum and Kanban methods divide large and complex tasks into smaller chunks and complete them according to a specific process.
- Both methods continually improve and optimize operations and processes.
- Both methods focus on the workflow and encourage team members to participate in the process.
3.2 Differences between Scrum and Kanban
Scrum is a great way to develop products and projects. Kanban is the perfect way to support manufacturing.
The difference is the practical application of Scrum and Kanban. There are three major differences between Scrum and Kanban.
- Plan and repeat
The Scrum method emphasizes the schedule. The Scrum team provides a priority list of tasks that need to be completed, completes the function, and ships it to the customer. The team must decide to undertake a task that it recognizes can be completed within the sprint.
Every two weeks the team ships the finished product to the customer. The parties then meet to discuss improvements, discuss process optimizations, and switch to the next sprint. The process repeats, you can predict the workflow accurately and manage it efficiently.
Kanban has no timeboxing or repeating the process. Continuous improvement is continuously practiced in the product completion process.
- Roles and responsibilities
In a Scrum team, at least three parties, the PO, the Scrum Master, and the development team, can specify the work process. Each party is bound by separate responsibilities and needs to work together to balance requirements and finished products. The Scrum team has all the resources it needs to complete its business.
The Kanban method has no rules regarding its role. It means that one person takes on the role of project manager or supervisor. There are no rules for roles, especially in large and complex Kanban projects. Kanban teams do not have to be interpersonal groups like the Scrum method.
- Management board
The Scrum board is labeled with columns to reflect the steps of the workflow. The tasks run in sequence, running each sprint all in a matter of weeks. Move them to the completed state and finally handle the sprints that have the standby state.
Kanban boards are labeled on columns to indicate the "flow of work" status. Each column has different limits and doesn't require time, so it doesn't repeat the process like the Scrum method. The process continues to run with additional tasks and is reevaluated as needed.
So which method is better? It is necessary to consider the needs and strategies of your company so that you can choose the appropriate method. Companies can also use the Scrum Bang method, which combines the Scrum and Kanban methods. Scrum Van introduces you as a simple process for managing complex projects. Currently, Scrum Van is best deployed during website development, system development, or maintenance.
