You have probably read about “at scale” implementations, activity based offices, globally distributed teams, SAFe, Agile transformations and outsourcing. Beware. Danger can be lurking beneath the surface of these popular phenomena.

Reactions to “No CEO” by the BBC

no-ceo-by-ceo-guru-bbc

When the BBC published their “No CEO” piece where Crisp is featured with an article and a 4 minute video, there were a lot of reactions. Friends cheered on Facebook. Colleagues gave a thumbs up on LinkedIn. The article was featured on Hacker News and Slashdot. Here are our reflections on some of the comments we found.

Scientific method applied to performance improvements

build-measure-learn-loop In my team, we are working on improving real-time performance for our main service. The goal is to have response times below 100 ms in the 95th percentile and below 200 ms in the 99th percentile for certain database volumes and request frequencies.

We don’t know what will be needed to reach this goal. We have some ideas, but we don’t know which one, or which ones will do the trick. We call these ideas “experiments”.

We can estimate each experiment, but we don’t know how many we will need to do to reach the goal.

This is the story of how we apply the scientific method to working with performance improvements.

How to append to lists in Ansible

Since I have found the Ansible documentation to be lacking, and StackOverflow insufficient in this matter, I feel the need to share how you can append to a list using Ansible.

I’ve created a demonstration playbook and published it on GitHub. See: https://github.com/betrcode/ansible-append-list

Continuous Delivery of custom WordPress using Vagrant, Ansible and AWS

Vagrant + Ansible + AWS = <3

Vagrant + Ansible + AWS = <3

The www.crisp.se website is based on WordPress, with a custom Crisp theme.

This is the story about how we’ve developed our custom WordPress theme, how we’ve made it easy for any Crisper and external consultants to work on the theme, how we’ve setup version control, continuous delivery, staging and production environments on Amazon Web Services (AWS). And how all of this is setup with absolutely no automated tests whatsoever.

Dedicated Scrum Master or not?

Should the Scrum Master role be full time or part time? What if there is not enough Scrum Master work to do? Can the Scrum Master also do other work in the team? Can the Scrum Master be Scrum Master for several teams?

There was a debate about this and Scrum Alliance created the Scrum Master Manifesto in 2011.

Even though this has been debated by many minds before, I still get asked what my views are on this topic.

I’ve done all kinds of variations on this role. I’ve been a dedicated Scrum Master for a single team. I have done the SM role and a developer role at the same time. I’ve been a Scrum Master for several teams at the same time. These alternatives have their own advantages and challenges. In this post I intend to describe my view and recommendations.

Crisp DNA is now open source!

We get a lot of questions about how Crisp works and why, especially from other consultants looking to create something similar. After many years of experimenting we’ve converged on a model that works well, basically the sweet spot between being an independent consultant and being an employee. So we decided to open source it.

In January 2015, at Crisp Hack Summit 10, Mats Henricsson, Henrik Kniberg and Max Wenzin huddled up and created the first version of the open-sourced Crisp DNA. It is published at http://dna.crisp.se/

The Crisp DNA is version controlled using Git and both Crisp DNA repository and Crisp DNA web site is hosted at GitHub using GitHub Pages. The web site is a bunch of static web pages and images that is generated from Markdown and Textile files using Jekyll. This is the same setup that GitHub themselves use.

By using open, version-control friendly formats such as Markdown and Textile, we hope to benefit from the open source community which can fork our model, make changes and perhaps suggest improvements. This can actually change how Crisp works!

Why I prefer ToDo over Trello for agile teams

The Gist

  • ToDo has a flow. It knows about cycle times and about being DONE. Trello does not.
  • ToDo has Planning Poker Estimates. Trello does not have any estimates.
  • ToDo has automatic burn up charts. Trello does not.
  • ToDo has swim lanes which groups cards by your dimensions. Trello does not.
  • ToDo has Work-In-Progress limits. Trello does not.
  • ToDo has upgrade possibilities to the full tool set of Projectplace. Trello has a bunch of plugins from different vendors of various quality.

Five team principles

Building a well-functioning software delivery team is complicated. There are many factors to consider. Current team (if any), needed skills, available people, company politics etc.

There are some fundamentals that often (but not always) seem to work.

My fundamental principles for teams

  • Static
  • Cross-functional
  • 5-9 people
  • Co-located
  • Dedicated team members (belong to only one team)

I find these principles to be a useful basis for discussion, when helping managers configure their teams.

The principles are goals, and one must realize that all cannot be achieved all of the time, nor instantly.

Case Study of Mobile Team at Projectplace

Projectplace

Projectplace

I am currently working as a Scrum Master for multiple teams at Projectplace in Stockholm, Sweden. One of those teams is the Mobile Team. They are developing Action Boards for both iOS (iPad) and Android platforms. These Action Boards are also available in the Customer Preview of the Projectplace web service. Both Web Team and Mobile Team share the same API’s. The iPad app is planned to be released in 2-3 Sprints from now.
This case study can be written from many perspectives, but in this article I am going to focus on how we are working with the challenges of having a distributed Scrum team.

My first Visual Agenda

I have been reading Gamestorming lately and found that I’ve practiced many of the games and followed most of the principles of game design already.

Visual Agenda

Visual Agenda

However, there are a lot of new things in that book that I’d like to try. Today I tried drawing a Visual Agenda for the first time.

I think it was well recieved, because the team didn’t want to erase it even though we were running out of whiteboard space during the meeting. 😉

The purpose of the exercise was to make it a bit more fun and rememberable, to show the team that they and the project are important enough to spend more time than usual on an agenda.

If you are a recurring victim of my presence, you can be sure to be exposed to many more of the games from the book; Gamestorming.
