Scrum + Kanban = Scrumban

Scrum Project Management SoftwareIn the spirit of true Agility which encourages flexibility and a "whatever works" approach, Scrumban has become a popular framework in Agile software development.

This combination of Scrum and Kanban incorporates the best of both world, and is commonly used in product development and maintenance. Scrumban integrates the benefits of both methods: the fundamental elements of Scrum’s Agile working are combined with Kanban's drive towards lean process improvement.

While initially used for the transition from Scrum to Kanban, Scrumban has by today emerged as a standalone methodology. In a nutshell, Scrumban teams apply the Scrum approach in their development activities, and use Kanban to oversee, manage, and continuously improve their work (Kaizen).

One of the really important (but often overlooked) values of Scrumban is that its principles and practices don't exclusively apply to software development. Scrumban may be used in other business functions where it will help promote lean thinking, waste reduction, and process improvement.

Scrumban = Scrum + Kanban

Scrum focuses on small, cross-functional, self-organizing teams, requiring team members to split the work into a list of small, concrete deliverables. They will then set priorities and estimate the relative effort cost of each item. Scrum is based on short fixed-length iterations (usually 1–4 weeks), with potentially shippable code demonstrated after each iteration, and uses retrospectives to optimize the process after each iteration.

Kanban is a workflow visualization tool. By splitting the work into pieces, writing each item on cards, and putting them on a board you can move these tasks around, visualizing the flow of works. Kanban has a few basic columns to group tasks (To do, In progress and Done) to illustrate the status of each item in the workflow. Setting Work In Progress (WIP) limits helps make sure all team members are tasked to capacity.

Scrumban is a combination of these two methods. It helps increase product quality, shorten lead time and promotes continuous improvement.

In practice, implementing Scrumban is no rocket science. Kanban helps make the flow of work visible, which in turn helps you discover bottlenecks in your process, enabling continuous improvement. When applying the Scrumban approach, you will initially want to maintain current roles and responsibilities. Scrumban is all about an evolutionary change, there's no need to "rip and replace" any processes. 

When to use Scrumban?

  • For the maintenance of various applications
  • For event-driven work such as IT support
  • In Agile teams focused on new product development

This short table below should help you better understand the similarities and differences between Scrum, Kanban, and Scrumban:

Elements Kanban Scrum Scrumban
Roles No described roles Product Owner, Scrum Master and Team roles Team + needed roles
Ceremonies No daily stand up, no review and retrospective meetings Daily stand up, review and retrospective for improvements Daily stand up supported with the Kanban board for status management
Workflow Continuous workflow No workflow / Case-dependent Workflow defined, WIP limits are used
Iterations No iterations Sprints (1-4 weeks) Continuous workflow
Change Management and bug fixing Just in time Next sprint Can be added at anytime to the board

Using Kanban can result in higher efficiency with the combination of Scrum for development and maintenance teams.
