Scrum

Scrum is an agile, incremental development method. With each increment, the team delivers a potentially usable product. In the process, changes to requirements can flow into the project in a controlled manner.

The focus is on the self-organisation of the team. The Scrum Master supports this in order to enable trouble-free work.

The development team does not need a project manager. The product owner, as the person responsible for the product, takes over the technical requirements and defines, prioritises and, if necessary, adapts them. The Scrum rules contribute to transparency and trouble-free development cycles (sprints).

Kanban

stop start - start finishing

Kanban is a procedure that reduces the number of parallel tasks, the work in progress (WIP), when running through a value chain and thus achieves faster throughput times.

In the process, problems, especially bottlenecks, are quickly made visible.

Kanban comes from lean production and became known through its use at Toyota. The procedure has since been adapted to software development and organisational processes.

Kanban is a wonderful tool to visualise personal tasks and to work through one’s own tasks in a structured and focused way.

comparison of scrum & kanban

Scrum

  • Iterations of equal length are prescribed.
  • Team agrees on a specific amount of work to be done in the next sprint.
  • Velocity = baseline metric.
  • Teams should be cross-functional.
    Requirements must be completed within one sprint.
  • Burndown charts are used as a metric.
  • Indirect WIP limitation due to the limited quantity in the sprint. Optional WIP limitation within a sprint.
  • Estimates are mandatory.
  • No new requirements in the current sprint.
  • Three prescribed roles (product owner, scrum master, development team).
  • Scrum board belongs to the team and is emptied after each sprint.

kanban

  • Iterations are optional. Different cadence for planning, re-selection and process improvement.
  • Commitments are optional.
  • Cycle time = basic metric for planning and process improvement.
  • Expert teams are allowed.
  • Completing requirements takes as long as it takes. There is no requirement on the size of a requirement.
  • No specific diagram type is prescribed.
  • Proven diagrams are CFD (Cumulative Flow Diagram) and Chart-Control.
  • Work-In-Progress (WIP) is directly limited.
  • Estimates are optional.
  • New requirements possible at any time within the WIP limit.
  • No prescribed roles
  • Board can be shared by 1-n people and is continuously maintained.

Use of scrum and kanban

Scrum and Kanban can be used in many places and offer different focuses.

Over time, the ScrumBan construct has also been established, which aims to combine the strengths of the different frameworks in order to increase efficiency even more.

Nevertheless, we would like to advise testing each framework on its own first in order to identify the strengths and problems. It is rather counter-productive to “cherry-pick” from the respective frameworks, because problems arise during implementation.

What all frameworks have in common is that they are meant to uncover problems – so that we can solve them faster. For this reason, it is desirable that with the use of a framework, the underlying problems become visible.

LeSS is a framework for scaling Scrum across the organisation. 

If teams are experienced in working with Scrum, then scaling can contribute to transformation in the company.
