Impact Mapping - great book, great tool

I've just got my copy of the [Impact Mapping](http://impactmapping.org/book.php). It was long awaited for me and apparently for others too since it went out of stock in a couple of weeks. My own copy was 'hijacked' by a client that read it overnight and started to use Impact Mapping the day after. In this post I'll write down some thought after reading the book from cover to cover. I wanted to do this on Amazon but sadly I cannot since they only accept review from people how bought the book directly from the. Well - this will have to do instead then. I'll hint right now that this would be a 5-star review (to add to the 9 other 5-start reviews that's already on Amazon). ### What is it? Impact mapping is described to great effect at the official site; [www.impactmapping.org](http://www.impactmapping.org/). So here I'll present my own journey up to Impact...

Unearned trust

Today I’ve experience a rare thing. I went into a restaurant in Stockholm. It was a new place to me I’ve never been there before, to my knowledge. The restaurant was crowded as it was lunch hours. One by one the queue in front of me disappeared and went out the door again. So I started to realize that something wasn’t right here. Food’s out? Food’s bad? Only veggies left? When I came up to counter to order the man behind the counter let me and then said: “The card machine has not been acting up during the last hours. Let’s see how this goes…” Sure enough - the card machine was broken. I couldn’t pay. So I put my card back into my pocket and turned around to go. Then he said it: “You know what … It doesn’t matter. Take a seat and we’ll bring you your meal...

TDD for kids

I had the opportunity to do something exciting yesterday. I was invited by my good friend Tristessa to teach a class on programming for her 13-14-year olds. She teaches at the International School of the Stockholm Region and had introduced them to programming just a couple of weeks before I came. Since the first time I learned TDD I’ve always thought that it’s a bit like thinking like a child; challenging the code, come up with more examples, try to break/understand your code and just being curious. Also - when TDD works it feels much like doing a puzzle - the next piece just comes to you in a nice way, another kid-activity. So I thought I’d try to teach them TDD during an hour and a half. We did the Fizz Buzz kata together and during the class brushed on a number of interesting subjects. They also did somethings during...

Code Freeze, Recompile and Code generations - stuff thats not that scary with CD

Sure enough… There’s an abbreviation for Continuous Delivery. It’s CD.  I think this means that it’s important :) The last couple of days I’ve run into a lot of expressions, true-isms and problems that we take for granted that is turned a bit on their heads when looking into releasing often. And with often I mean real often - like all the time. No really I mean continuous delivering. Yes, I know that if first feel a bit scary and unachievable  but in this blog post I’ll try to show you a couple of things that make that strive worthwhile. I think Continuous Delivery? | | |:————————————————————————————————:| | | | From Industrial Logic | So the short and sweet introduction is really this; push EVERY change to your code, configuration and environment to production. Do that all the time. To unwrap that it of course mean that you need to have...

Specification by example and Model based testing

My current client, Spotify, is really on forefront when it comes to good, solid engineering practices. There are inventors, leaders and all around great people where ever you look. So this gig has rendered me a lot of learnings, even in the areas that I don’t touch much (being hired as an agile coach that reads coding people…). So the first week or so heard the term “Model based testing” for the first time in my life. Investigating further I realised that it had strong similarities, technology-wise, with Specification by example. And there’s some fundamental differences in the thinking and reason behind each approach too. In this post I’ll take a brief look to clear out the differences and similarities  I think that you can have great use for both approaches but you should probably know why or you’ll find yourself fighting the tools and process for a better fit. Model based testing...

You say 'continuous delivery', I say 'limit WIP'

Continuous delivery is something that everyone seems to be talking about these days. And it’s very cool. Put very simply you can say that it’s striving for releasing every change you do in your code base and configuration to the production environment. This can seem like a very daunting task to take on but if you think about it, it only has to do with us taking on to much work in process. In this blog post I’ll elaborate on some thoughts around that. Continuous delivery is not hard at all This little conversation took place the other day when I explained continuous delivery for a colleague: “When is the easiest day to release a system?” “Huh?” “The first day. Continuous delivery is to just keep doing that ever day” Yeah - it’s one of those; that’s easy for you to say, but there’s a great amount of truth in there as well. It is...

Top 5 Agile change tips 5 - Used visualized data to improve

This is the last post on my top 5 ways of making sure that your agile change initiative succeeds. Here's the list - in order of importance: 1. Get a great "Or else"-reason for doing this change 2. Sit together 3. Let them change how they work 4. Support the initiative 5. Use visualised data to improve (this post) ### 5 - Use visualized data to improve If there's one thing that I've seen team really get an aha-experience from it's visualising  Simple stuff - just putting your work items on a board, having to talk about how your process actually is laid out or putting a little picture of yourself on every item you're currently work on. Things like that. But lately I've also been addicted to having data as the basis of changes. Quite often we seem to change based on what we **feel** is the right thing to do. If you search out data you...

Top 5 Agile change tips 4 - Support the initiative

This is the second post on my top 5 ways of making sure that your agile change initiative succeeds. But this is not ideas made up in my head (MY GOD - the horrors...) but things that I've tried and failed miserably with. Over and over. And learned a lot from. This is the list - in order of importance: 1. Get a great "Or else"-reason for doing this change 2. Sit together 3. Let them change how they work 4. Support the initiative (this post) 5. Use visualised data to improve ### 4 - Support the initiative This should be a no-brainer but once you see it in action it's seldom handled correctly. If you want to change how people act and work you have to be a role model for that, supporting the new ways. This means that the change must start with management. Yes - start. No - it is not enough that...

Top 5 Agile change tips 3 - Let them change how they work

This is the third post on my top 5 ways of making sure that your agile change initiative succeeds. This is the list - in order of importance: Get a great “Or else”-reason for doing this change Sit together Let them change how they work (this post) Support the initiative Use visualised data to improve 3 - Let them change how they work You need to open up and let go off the wheel. An agile transformation is, if anything, a culture shift. Towards autonomy and from top level steering. This should go into the agile transformation too. In effect this mean, in the words of all agile coaches, to take it to the team. The guys that are going to live in this environment - they are the ones best equipped to know what to do about it. Hey - they are there right now. They probably even knows what doesn’t work too. Trust...

Dear Marcus ... there''s no "but" to follow. '

I’m turning 40 years old today. This is a letter to Marcus 60 years old. Or maybe a new version of my 20 year old self, if I ever invent a time traveling machine. If you’re not me you can still read it of course. But then think of that wrote this to myself. It’s pretty self-focused. Don’t think badly of me for that. Instead write one of these for yourself. Very inspiring actually! Dear Marcus (future and past), today 2012-10-09 you turned 40 years old. You are in a place of your life that you wouldn’t dream of and never planned to. I thought I’ll sum it up for you if you ever forget it (chances are!). The main point is that there is not “but…” in your description. Everything is like it is and there’s no ominous but that throw it all over end. You have Elin in your...
