SCRUM VS KANBAN: Friend or Foes?
15th Jun, 2021
One would be surprised to know how many people find it difficult to differentiate between Kanban and Scrum. These are two terms that are frequently used in the same sentence. They are both agile approaches and have considerable distinctions. Even though both agile approaches are designed to simplify workflow and teamwork collaborations to ensure the best results, it's critical to grasp the differences between the two to determine which is best for one's work environment.
Out of the two, reports show that scrum is used far more by teams. About 56% of units use Scrum, whereas only 5% of the teams use the Kanban framework. 8% of teams also use Scrumban, a hybrid of Scrum and Kanban, and the rest use other agile frameworks.

WHAT IS KANBAN?
Kanban originates from lean manufacturing, and it means "signboard" or "billboard." It's based on the ideology of visualizing everything. It uses visuals to streamline and manage the workflow and processes. It works on the philosophy of the complete elimination of waste. Kanban aims to use visuals to improve workflow and processes.
The main objective of Kanban is to ensure that the workflow proceeds smoothly at an optimal speed by identifying the potential issues in the system and fixing them accordingly. It keeps on experimenting and improving the system consistently by making the policies explicit and describing the process accurately. It helps you improve collaboratively by using models and empirical scientific methods to implement continuous and evolutionary changes.
Work-in-process or WIP limits are key Kanban concepts used by all teams to manage their workflow actively.
Companies like Nike, Zara, and Pixar Studios use Kanban.
As visualization is a vital Kanban practice, the Kanban board sets that process into action. This is how it works:
● Using the Kanban board, all the team members can instantly see how the tasks are moving throughout the process and check their current positions like- to do, in-process, and done.
● As it's a very simple board, there is a lack of rules, so it is recommended to divide the work into better-defined stages to make the process easier.
● Kanban is more than just adding items to the board, it's also applying a 'pull process.'
● The key is to set up an easy way to visualize the work and create an area for social interactions to establish the team capacity and spot and correct bottlenecks to streamline the ideal flow.
Benefits of Kanban Use
Some benefits of Kanban use are better visibility of work and improved transparency, improved communication and focus, and better flow of control. Many people complain about team collaboration issues, which is one reason to implement Kanban.
Challenges in Kanban Use
Kanban, as an agile method, is not as simple to implement as it appears. People are frequently unable to utilize Kanban to its full potential due to a lack of proper training and misunderstanding. It is a complex tool with numerous capabilities, and only those who comprehend it entirely will realize its full potential, while others are not able to get optimum results.
WHAT IS SCRUM?
Scrum is an Empirical Process framework that is required to help teams work together. It helps to deliver optimum business value to the customer in the shortest period. Scrum is an iterative framework used to break down complex problems into smaller chunks.
Scrum aims to solve complex problems while delivering valuable products.
It offers product development for every business. Companies like Apple, Google, Facebook, Yahoo, Spotify, etc., all use Scrum.
A Scrum board shows a visual status of a sprint and is split across different stages of the workflow. In contrast to the Kanban board, which lacks such a concept, a Scrum board is reset after each sprint.
A Scrum team constantly monitors the work, and through a daily scrum meeting which is 15 minutes, the team analyses communicate, and correct the problems. There is a heavy focus on cross-functionality.
The scrum team has three roles divided among the members:
3. Scrum Master
A Scrum project is facilitated by a Scrum Master and is often referred to as a servant leader denoting pseudo leadership, less focused on management. People who develop products and estimate their work are part of the Scrum Team. Scrum has a fundamental 30-day maximum limit for a 'sprint.' Progress is made in sprints. Sprints are short-term goals that can last anywhere from a day to 30 days. It can include days of work as per the sprint duration, and a day of sprint review. The Sprint goal is to produce a potentially shippable product after each sprint. The length of the sprint determines the planning and reviewing periods on which the product is discharged tenure is further determined. Scrum detects everything that gets in the way of the delivery.
Benefits of Scrum Use
Scrum involves detailed short-term planning with constant feedback. It is a simple, empirical process that fosters openness and demands visibility. It uses comparatively simple techniques and work artifacts to optimize the working environment and reduce organizational overhead.
Disadvantages of Scrum Use
If people aren't committed or cooperative, there's a good chance the product will fail. Other than that, there are various areas wherein Scrum is deemed inapplicable, such as Projects with a fixed time and fixed price rate along with a fixed project. Scrum is not considered the one fix for all kinds and can sometimes overkill projects.
Kanban vs. Scrum: Major Differences
Instead of asking Kanban vs. Scrum, one should start asking Kanban or Scrum or even Kanban and Scrum. The significant differences between the two are:
● Ideology: Kanban is based on fixed work scope and measuring time. On the other hand, Scrum requires a fixed time schedule and measures work to help teams work together.
● Roles: Kanban is flexible to changes and relies on time-boxing and forecasts. There are no predefined roles for the workers, and commitment is not necessary. Scrum is focused on planning, and there are predefined roles for the members like scrum master, etc.
● Estimation: Estimation plays a vital role in Scrum, whereas in Kanban, it is optional.
● Metrics: The metric used in Scrum is velocity; Kanban uses Lead time, cycle, or WIP.
● Approach: Scrum follows a structured approach; Kanban is an of continuous changes and improvement.
Scrum vs. Kanban: The Conclusion
Scrum and Kanban are both popular agile frameworks that are pretty different from each other. They both have their pros and cons, focusing on optimizing the work environment in their way.
Thus, only after a thorough investigation of their working environment can one determine which one to use.
