My Reading Backlog

I saw some people sharing their reading backlog and thought it was a fun idea to write mine down as well. Looking back at 2018 I was quite surprised how much books I managed to read.

If you know some books I should add to my backlog, please let me know!

A small note: I have not prioritized my todo-list, whenever I finish a book I pick something from it I feel like reading at that moment and start.

Bye Bye Velocity. Hello Throughput.

As published by Louis-Philippe Carignan on Scrum.org

The Professional Scrum with Kanban (PSK) course has now been out for more than 6 months at Scrum.org. As one of the first few trainers who wanted to teach this course when it came out, I find that it is a great way to combine the Scrum framework with Kanban as a strategy to deliver value to your customer.

Out of the many topics that we talk about in this class, I’ve found that the use of throughput instead of velocity/capacity to be a positive change. I’ve taught the regular Professional Scrum Master (PSM) course for about 6 years now and when I get to the Sprint Planning slides, we usually extend the conversation around velocity and capacity. I pull up my complementary slide deck around relative estimation, poker planning, charts to track velocity and we spend an additional hour on this topic. I answer questions around the meaning of story points, how they should be understood, tracked and used in multi-team Agile project.

In the PSK class, this conversation is completely different. When I get to the Sprint Planning slides, I point out that the throughput history is used as an input to the Sprint Planning. With a few examples, I show how easy it can be to get from your electronic Agile tracking system (Ex: Jira) or on your physical Kanban board.

I then get a new set of questions from students which I find a lot more interesting. The conversation goes quickly around the variation in the size of the Product Backlog Items (PBIs) that are taken by the team at Sprint Planning. I can also tie it back to Little’s Law where limiting work in progress will increase throughput, thus helping students see throughput linked to limiting work in progress. There are very few questions around understanding throughput. Students find it is a metric that makes sense to the business compared to story points.

While our industry has talked about poker planning and story points since almost the beginning of agility in 2001, I think it is more than time that the conversation at Sprint Planning shifts to historical throughput instead of using velocity. Maybe one day in the software engineering museum, we can see a deck of poker planning cards next to a set of punch cards.

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.
