What is Best, Scrum or Kanban?

[article]
  • Inspect amp; adapt (improve your product and process based on facts)
  • Pull scheduling (see below)
  • Good communication and collaboration

Self-organizing teams is when the team themselves are supposed to figure out how to solve problems, remove impediments and optimize their process. They should base their decisions on facts to inspect and adapt accordingly.

Pull scheduling means the team is pulling work instead of having it pushed. This will limit work to capacity and lower stress, which is bad for both health and quality.

This is why I prefer Scrum

So, now that you know what Kanban and Scrum is, it's time to decide which is best.

I start by putting the Scrum T-shirt on. Look further down if you like to read the part where I love Kanban.

I concentrate on some areas where Scrum and Kanban differ:

  • Iterations - In Scrum you work in iterations. Kanban sees development as a forever ongoing flow of things to do.
  • Commitment - In Scrum a team commits to what they will do during a sprint.
  • Estimations - In Scrum you need to estimate to be able to have a velocity. In Kanban it's optional since focus is on time-to-market.
  • Cross-functional teams - That's one of the pillars of Scrum. For Kanban it's optional.

Efficiency driven by commitment

By asking a team for a commitment they will get a positive stress knowing that people from outside will see if they can do what they committed to. It also gives an energy boost at the end of the sprint when the team has the goal within reachable distance. After the sprint, the team can feel relaxed and gather some new energy for the next sprint. It's psychologically nice to not feel you are in the middle of a never-ending stream of things to do. Instead Scrum concentrates on one sprint at a time and allows you to focus only on those things you have decided to take on in the sprint. By working in fixed length iteration you get a nice rhythm the whole company can feel and adapt to.

The value of estimating

Estimating is not a waste of time since valuable information is transferred from the product owner while the team asks what they need to know to be able to estimate. The same thing applies to commitment. To be able to commit team members need to know what they are committing to. They simply have more interest in getting information from the product owner so they listen more carefully. And they are just asking for the information they need which makes the meeting very efficient.

Even though you can predict when a project is done, just by counting stories left, it is more precise if each story is estimated as well. Prediction is important when more departments, like marketing, are dependent on your work. It gives a more serious feeling.

Slack at end of sprints

If there are some time at the end of a sprint that's valuable even if the time is not big enough to start developing new features. This is time developers can use to improve code quality or the development environment. Both will give better efficiency in the long run.

Build teams with cross-functionality

Working together in a cross-functional team is a psychological thing. You are able to go the whole way from concept to released product together as a team without dependencies. You are not just a cog in the machinery. It's also fun and helps you grow as a person. By helping each other, knowledge is spread which lessens dependencies on each person. It
