Differences Between Scrum &Kanban

As posted by Al Shalloway on LinkedIn

Looking at differences between Scrum & Kanban can help us see which will work better for us.

  1. Scrum requires planning the sprint. You can plan in Kanban but it’s normally isn’t done.
  2. Scrum requires cross-functional teams. Kanban doesn’t. While making it more flexible if also may miss the opportunity for team structure improvement.
  3. Scrum requires starting with its roles, practices, events & artifacts. Kanban allows you to start where you are & provides a transition model for improvement.
  4. Scrum improves by removing impediments. Kanban improves by focusing on shortening cycle time.

Teams that don’t like to be told what to do may resist Scrum. Kanban requires more discipline from the team than Scrum.

Factors to consider when deciding which to use:

  • culture– including resistance to being told what to do &attachment to roles
  • nature of work being done
  • ability to create cross-functional teams

Note that executives can better relate to Kanban’s focus on flow. Combined with its insistence on visibility, executives can better understand the importance of managing workload.

In few cases is one clearly superior to the other. Taking a blend of the two often makes sense. Doing this is not difficult.

How to Implement Hypothesis-Driven Development

Practicing Hypothesis-Driven Development is thinking about the development of new ideas, products and services – even organizational change – as a series of experiments to determine whether an expected outcome will be achieved. The process is iterated upon until a desirable outcome is obtained or the idea is determined to be not viable.

Why Agile Teams Should Estimate at Two Different Levels

It is very common for agile teams, especially Scrum teams, to estimate both their product backlog and sprint backlogs. In this article, Mike Cohn will address:

  • Why estimating both the product backlog and sprint backlog can be useful even though it seems redundant
  • Why teams should estimate the two backlogs in different units
  • When teams should estimate
  • Whether all teams should estimate

Although I think you should not try to use hours for estimation, I agree using different valuations for an estimation is best. I find using T-shirt sizes for PBIs and Story Points for SBIs work well.

Steps he took:

  • Defined a clear goal (purpose) of the workshop
  • Used Impromptu Networking to introduce a little fun which would make it easier to make a personal connection with each other.
  • Used Appreciative Interviews to let them discover what they would need to become a successful team.
  • Used Nine Whys to discover both their individual purpose and business reason for the team’s to exist.
  • Used What I Need From You to express their needs from each other.
  • Used Min Specs to identify team needs and created a team manifesto.
  • Used 15% Solutions to identify what the first step would be for everybody to start working effectively with Scrum.
  • Used Social Network Webbing to close the day in a positive vibe.
  • Used a number of energizers and punctuations to take a break from the intense interaction of Liberating Structures.
