I’ve spent years experimenting with how to teach kids programming, mostly using Scratch. But now we’ve found a new favorite: LearnToMod! Kids love Minecraft, and LearnToMod is entirely based on Minecraft, so it’s a perfect match!
We now do a Mod Club every Saturday evening, my older kids (9 & 11 years old) and some of their friends. It’s basically a programming school based on LearnToMod and Minecraft programming. Reeeeaaaally fun, the kids go wild (OK, me too)! AND they learn lots while doing it. To them it’s ”magic powers”, not “programming skills”.
I made a 5 minute video showing how it works:
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!
Here are the slides from my keynote “Focus” at BrewingAgile Gotheburg. It was about how to achieve more by working less.

Strangely, in most companies people are considered perfectly healthy until they suddenly burn out. While in reality, it seems that a large number of people are somewhere between those two states, and could use some help to get more focused and less stressed.
We had a guy, Mattis Erngren, visit us at Crisp and do a session on focus training and meditation. Very pragmatic, interesting, and useful session. Highly recommended. Mattis and his company Lightly are on a mission to make focus training a standard offering at all companies, just like other health benifits like gym and such things. The brain is a muscle and it needs training too, to stay in shape.
So go ahead and contact the guys at http://lightly.io and bring them over. They offer free trial sessions so it’s really a no-brainer.
Incidentally, Jeff Sutherland was at the session at Crisp, and revealed that he used to be an avid meditator, and that Scrum was actually conceived during a meditation session. As in, the idea behind Scrum popped into his head right after a session. Interesting! When you clear your mind from all the noise, you make room for the really powerful stuff.
I travelled with Emma (6 yrs), she’s been wanting to travel with me (alone, without her 3 siblings…) for a long time, so she’s really happy! Thanks Mary & Tom Poppendieck for being her bonus grandparents during the whole trip

I was deeply moved by this letter. I’ve seen how Scrum and similar pull-based approaches not only improve productivity, but reduce stress and improve quality of life for people, and this is a powerful example. I asked the sender if I may share it with the world, and thankfully he agreed. Here it is:
Recently I picked up a version of your free online edition of “Scrum and XP from the Trenches, How we do Scrum” and I have to say it changed my personal and professional life.
I have been and software developer on interactive voice response systems for close to 20 years now.
A few months ago I was speaking with a colleague and mentor of mine about his efforts to become a certified Scrum master. Up until this point I had never really been exposed to Agile and Scrum in detail and only knew some of the jargon. My colleague suggested that I research and learn more about the Agile philosophy and in particular Scrum. Since I have been suffering from a poor work life balance almost my whole career I decided to pay it some attention.
I read your paper on a Saturday night and decided that Sunday that I would implement Scrum start on Monday morning. So I quickly pulled together a spread sheet with what I had that night and formalized the excel sheet that was our product backlog. That Monday I held my normal morning meeting with my development team and the rest is history.
The short of it is that my team is finishing up its 3rd sprint next week and we all love it. A lot of the stress that was keeping me up at night has completely gone away. I feel in complete control when I come to the end of my work day. In the past two months I have even hung out with my family on Saturdays and Sundays. I have begun to add more of a balance back to my life.
I really wanted to thank you for writing this paper and putting it out in the world for free. The tips that your paper offered have literally saved my marriage and probably my life.
Thank you again for you effort.
Wow, it’s been a crazy period. Sydney, Trondheim, Oslo, 10 talks in 2 weeks! Didn’t really plan to do that much, but one thing led to another. Fun, but exhausting!
Here’s a high-quality video recording of the Smidig 2014 keynote (on Spotify engineering culture). The conference organizers say it’s the highest-rated talk they’ve ever had! Cool :o)
Here’s a shorter version with much the same content, in the form of a two-part animated video series, for the impatient.
Here are the slides for my talk “What is Scrum?” at KTH (Royal Institute of Technology). It was a guest talk at a course called Projektstyrning. Hoping to inspire young entrepreneurs to plant agile DNA in their companies from the very beginning. Last time I spoke at KTH was 6.5 years ago, that’s when I met the first Spotify team, and I’m really happy to have been able to influence and participate in their journey!
Here are some sample slides from the talk:
Many common organizational problems can be traced down to management of Priorities and WIP (work in progress). Doing this well at all levels in an organization can make a huge difference! I’ve experimented quite a lot with this, here are some practical guidelines:
This is a journey in progress, not a journey completed, so the video is somewhere between “How Things Are Today” and “How We Want Things To Be”.
At Spotify we’ve been experimenting a lot with various ways of visualizing the “health” of a squad, in order to help them improve and find systemic patterns across a tribe. Since a lot of people have been asking me about this, I wrote up an article about it together with coach-colleague Kristian Lindwall.
Read it on the Spotify labs blog: Squad Health Check model – visualizing what to improve.
Some sample pics below:
Here’s the thing. Suppose you introduce a change X to your workplace, and then business improves noticably. That doesn’t mean X caused the business to improve. Well, MAYBE it did. Or perhaps business improved for other reasons, and X was actually detrimental, and business would have improved even more without it. So did things work out well because of the great X, or despite the lousy X? You’ll never know, unless you could rewind the clock and play out the same scenario without X. Correlation doesn’t imply causation.
So people like me who work with organizational change, we are in the business of pseudo-science. We get customer feedback and anecdotal evidence, but we can’t actually prove that we are doing any good, it’s just opinions and observations and guesswork. I think that’s fine, but let’s be honest about it
This is a journey in progress, not a journey completed, and there’s a lot of variation from squad to squad. So the stuff in the video isn’t all true for all squads all the time, but it appears to be mostly true for most squads most of the time :o)
Here’s the whole drawing:
Here’s Part 2.
So, now I’ve spent 2 days with 600 projects managers at a PMI conference. Totally different from the usual crowds I hang out with. Fascinating to hear stories about project management successes and failures in all kinds of industries – from warzone reconstruction projects to eurovision song contest.
2010-2011 gjorde RPS en bra grej. De byggde ett system (Pust Java) som gjorde polisen mer effektiv. Poliserna fick datorer i sina bilar och kunde direkt registrera brott. Därmed behövde de inte åka in till stationen för att avrapportera lika ofta som med gamla systemet. Systemet var skräddarsytt för att ge hög användarnytta, och projektet blev en framgång. Pust Java blev finalist i CIO awards “project of the year 2011″ och DN skrev en helsida “Polisen rapporterar betydligt snabbare med ny metod“. Systemet var inte perfekt, men en bra start. Poliserna sa att det var bättre än vad de hade innan, och folk var optimistiska inför systemets framtid.
Sedan hände något tragiskt. Istället för att vidareutveckla och kontinuerligt förbättra systemet, så valde ledningen att skapa ett nytt system från grunden (Pust Siebel) med undermålig teknik. Det blev ett fiasko. Ursinniga poliser klagade på att en avrapportering kunde ta flera timmar – “Pust Siebel gör en helt frustrerad och på gränsen till vansinnig!” – och saknade det gamla systemet. RPS hamnade i ett mediadrev. En poliskälla uppskattade samhällskostnaden till 10 miljarder kr!
Efter massiv kritik från både media, poliser, skyddsombudsmän och oberoende aktörer med insyn i projektet, beslutade RPS att lägga ner Pust Siebel. Nu är det allt fler som förespråkar att Pust Java återinförs
Varför spenderar en myndighet hundratals miljoner på att bygga något bra, för att sedan spendera ytterligare hundratals miljoner på att byta ut det mot något dåligt? Ännu värre: varför gör man detta trots att hela IT-avdelningen visste, och högljutt påpekade från början, att det nya systemet skulle bli sämre?
Syftet med denna artikel är att belysa och sprida lärdomarna, så andra företag och myndigheter slipper göra om liknande dyra misstag.
We are 35 people at Crisp now, and we are a decentralized organized with no managers. So how do decisions get made? This article is a direct translation of our internal wiki page “Hur vi tar beslut på Crisp” (how we make decisions at Crisp).
Getting started with ATDD
Have you ever been in this situation?
Then this article is for you – a concrete example of how to get started with acceptance-test driven development on an existing code base. Read on.
The purpose of this article is…
Actually, there is no purpose. There never is. I just write because I feel like it. Then I read the article and make up a purpose afterwards, and start eliminating anything in the article that doesn’t fit that purpose. But I won’t do that this time. Read on and you’ll understand why. By the way, this text is blue because it’s my second iteration. Black text is the original, first iteration. Here it is:
Let me tell you about my creative process. Every writer has a creative process. Otherwise they wouldn’t get anything written; well, at least not anything creative read more »
Technical Debt is usually referred to as something Bad. One of my other articles The Solution to Technical Debt certainly implies that, and most other articles and books on the topic are all about how to get rid of technical debt.
But is debt always bad? When can debt be good? How can we use technical debt as tool, and distinguish between Good and Bad debt?
Here are the slides for my keynote “Culture > Process” at the Paris Scrum Gathering. Amazing level of enthusiasm in the room, seems like this kind of stuff was exacty what people were looking for. Happy to see the ideas take such strong hold!
Yesterday I spent a very inspiring day with a big swedish bank, doing agile intros with 1200 people. We had developers, designers, testers, C-level execs, project leads, pretty much every role represented. The CEO opened with words about why they are determined to go all-out agile, and we had a speaker from another even bigger company describe their ongoing agile journey and amazing results so far. Very interesting. And best of all – no roadmap or other fake attempts at pretending that we know what the journey is going to look like. It was clear that this is a bumpy ride and that change will have to evolve gradually from bottom as well as from top.
The Elephant Carpaccio exercise is a great way for software people to practice & learn how to break stories into really thin vertical slices. It also leads to interesting discussions about quality and tech practices.
The exercise was invented by Alistair Cockburn. We’ve co-facilitated it a bunch of times and encourage people to run it everywhere.
Here’s a pretty detailed (shu-level) guide showing how to run the exercise.
Are you in a software development team, trying to be agile? Next time the team gets together, ask:
How do we feel about the quality of our code?
Everyone rates it on a scale of 1-5, where 5 means “It’s great, I’m proud of it!” and 1 means “Total crap”. Compare. If you see mostly 4s and 5s, and nothing under 3, then never mind the rest of this article.
If you see great variation, like some 5s and some 1s, then you need to explore this. Are the different ratings for different parts of the code? If so, why is the quality so different? Are the different ratings for the same code? If so, what do the different individuals actually mean by quality?
Most likely, however, you will see a bunch of 2s or worse, and very few 4s and 5s. The term for this is Technical Debt, although for the purpose of this article I’ll simply call it Crappy Code.
Congratulations, you have just revealed a serious problem! You have even quantified it. And it took you only a minute. Anyone can do this, you don’t have to be Agile Coach or Scrum Master. Go ahead, make it crystal clear – graph the results on a whiteboard, put it up on the wall. Visualizing a problem is a big step towards solving it!
Don’t worry, you aren’t alone, this is a very common problem. <rant>However, it’s also a very stupid, unnecessary problem so I’m baffled by why it is so common.</rant>
Now you need to ask yourselves some tough questions.
An unconference is like a normal conference but with no predefined agenda, no predefined list of speakers, no slides, and…er… actually it’s not very much like a normal conference at all! It’s more like an alternative to a conference. If the purpose of a conference is to collaborate and communicate, then an unconference will often fulfill the same purpose in a more simple, fun, and effective way!
There’s lots of ways of running unconferences. I’ve written a short book (or long article) about one specific format that I’ve been experimenting with over the past 5 years, mostly at companies like Crisp and Spotify.
By now it is well tested and works especially well for 1-2 day internal conferences with 20-80 participants. In fact, participants often say things like “all conferences should be like this!” or “best conference I’ve ever been to!”. Even the most rabid meeting-haters seem to like (or at least not hate…) this collaboration format
