Scrum and Kanban

Scrum and Kanban

What is the Agile Scrum Framework? How is it different from the Kanban approach. If you are applying the Scrum framework and leveraging the Kanban board, you might be thinking that Scrum and Kanban are the same. In addition, you might be wondering which methodology is a better fit for your work.

In this article, I have listed the core differences between Scrum and Kanban. Moreover, I also covered which framework is best suited with different type of work or teams.

 

Scrum in a nutshell

Scrum is an iterative and incremental Agile process framework to build complex products of the highest possible value. In Scrum, the team always works on the highest priority items first. The work is performed in short, time-boxed iterations or sprints. Each sprint begins when the team commits to complete prioritized user-stories based on their available capacity in the sprint. An iteration ends when the team has delivered a potentially shippable product increment of the product. Therefore, the scrum development team delivers business value to users at the end of each sprint.

The three Scrum roles - Product Owner, Scrum Master, and the Development Team - are defined below: 

  • A Product Owner decides what needs to be built and in what order.
  • A Scrum Master acts as a servant leader and coaches the team to follow Agile Scrum principles.
  • A Development Team is a group of self-organizing individuals who develop a high-quality product.

Scrum requires the below ceremonies to be conducted on a regular cadence:

  • Product Backlog Refinement
  • Sprint Planning
  • Daily Stand-Up
  • Sprint Review
  • Sprint Retrospective

Above all, Scrum is most suited for complex projects where things are more unpredictable than they are predictable. In complex domains, there is a need to collaborate with others, have an innovative mindset to investigate, experiment with different ideas, and adapt based on the learnings.

Kanban in a nutshell

Kanban is the most popular Lean framework. This approach works best for teams that have a continuous flow of incoming requests with different priorities. In the Kanban approach, each request or a work item is represented by a Kanban card that flows from one stage of the workflow to another until it is complete.

Kanban is very flexible in nature. New work items can be added to the backlog at any time. Even the workflow can change anytime. If team capacity changes, WIP limits get recalibrated. In addition, Kanban does not prescribe any roles or ceremonies. It optimizes an existing process by eliminating waste and improving time to market.

Compare Scrum and Kanban

Below section lists the core differences between Scrum and Kanban:

  • Scrum was formulated for complex product development to mitigate the limitations with the traditional Waterfall approach. Kanban, on the contrary, originated to manage work and control inventory at Toyota with Just-In-Time and Lean principles.

 

  • Scrum prescribes product teams to manage work within time-boxed, short, and consistent length iterations or sprints. However, Kanban specifies a continuous flow of work across different states.

 

  • With Scrum, development teams create a potentially shippable product increment at the end of every sprint. Therefore, teams can release code at the end of every sprint if approved by the product owner. With Kanban, teams can release code anytime or on-demand. 

 

  • Scrum requires three roles - Product Owner, Scrum Master, the Development Team. Kanban, on the other hand, does not prescribe any specific role.

 

  • In Scrum, the smallest piece of business value that a team delivers is a user story. Each user story may then be broken down into smaller tasks or sub-tasks. However, in Kanban, each work item is represented as a Kanban card.

 

  • Scrum is best suited for complex product development efforts that are unpredicatable in nature. Such complex efforts require research, experimentation, and an emergent design. Kanban, on the contrary, is best suited for simple and complicated efforts where things are more predictable than they are unpredictable.

 

  • With Scrum, sprint review and retrospective ceremonies are conducted at the end of every sprint to inspect and adapt. Though Kanban does not prescribe any ceremonies, teams may conduct a review meeting on a monthly or a quarterly cadence to review cycle time, flow efficiency, etc.

 

  • Scrum prescribes user stories to be estimated in terms of story points. However, Kanban does not require work items or Kanban cards to be estimated. In Kanban, estimation is optional. Some teams choose to estimate their work to have more predictability while others prefer to split their cards such that each of the cards is of the same size.

 

  • With Scrum, the most popular metrics are sprint burndown and velocity. Other useful metrics are release burndown, release burnup, and sprint burnup. The most popular Kanban metrics is cycle time. Metrics such as lead time, throughput, cummulative flow diagram (CFD), and control charts are also leveraged.

 

  • Kanban has more flexibility than Scrum as new work items can be added to the workflow at any time. 

 

  • Scrum prescribes ceremonies to be conducted on a regular cadence. For instance, the sprint planning ceremony must be conducted at the start of each sprint. Sprint review and retrospective ceremonies must be conducted at the end of each sprint. In addition, the daily stand-up must be conducted each day of the sprint. However, Kanban does not prescribe any cadence or ceremonies to be conducted. In Kanban, meetings are held as needed.

 

  • With Scrum, additional or new user stories should not be added to the active or an ongoing sprint. However, in Kanban, new work items or cards can be added anytime, provided the WIP (Work-In-Progress) limit hasn't reached yet.

 

  • In Scrum, the sprint backlog is reset after every sprint. However, the Kanban board is continuous.

 

  • To adopt Scrum, enterprises need to develop an agile mindset. Scrum requires a considerable change to the existing organizational structure and processes. As a result, leaders invest into Scrum training and create new roles or positions to build the best Scrum teams. On the contrary, Kanban does not require any significant changes to onboard onto this framework.

 

Now that you understand the differences between the two frameworks, you can decide which approach works best for your team. For more on Agile, Lean, Scrum, or Kanban, you may read below books:

5 Habits that Successful Leaders Have

Whether you are a business leader, an engineering lead, an entrepreneur, or an individual contributor, you might have noticed some common behaviors in people who lead. In this article, I will list down the 5 habits that successful leaders have in common.

 

  • Having a Positive Mindset

Great leaders have a positive mindset and they radiate positive energy to others. They strongly believe that they are they are confident, successful, and loved. Successful leaders read inspirational books, listen to motivational speakers, attend personal development workshops, and surround themselves with positive like-minded people. They hire right people on their teams, who not only have the right skills but also possess a positive mindset. Such positive minded people are self-motivated to perform at their best.

Check out the inspirational book, Think Positive, Speak Positive, Act Positive - A 3 Step Strategy to Embrace Positivity and Change Your Life.

 

  • Communicating Effectively

Effective communication is vital to the success of an organization. In 1938, Chester Barnard, the author of pioneering work in management theory and organizational studies, concluded that effective communication is the most important responsibility of leaders. Leaders listen effectively and encourage their team members to provide feedback. They keep an open mind, encourage collaboration, and promote consensus.

 

  • Empowering Others

Great leaders with a positive mindset empower the team. They target to create more leaders than followers.

The best-known entrepreneurs of the personal computer revolution, Bill Gates stated, “As we look ahead into the next century, leaders will be those who empower others.”

Leaders inspire their team, appreciate their work, help their team members to grow their visibility, connect them with right opportunities, and encourage them to fulfill their dreams. One of the richest American and successful industrialist, Andrew Carnegie, once said, “No man will make a great leader who wants to do it all himself, or to get all the credit for doing it.”

 

  • Continuous Learning

Great leaders always look forward to read inspirational books, listen to motivational speakers, read the autobiographies of other great leaders, and learn from successful self-development coaches. They often listen to audiobooks while driving to work. Leaders set aside some percentage of their earnings to invest in their learning. John F. Kennedy once stated, “Leadership and learning are indispensable to each other.”

 

  • Networking

Successful leaders spend their time and energy to build strong relationships with others. They like to connect with like-minded people. Leaders like to attend seminars, workshops, meetings, conferences, and any other public events not only to build their expertise but to meet new people who share their passion and purpose.

There’s a famous quote, Birds of the same feather flock together.”
