Discipline is an interesting subject. One that I find myself regularly talking about. Or discussing about. In the last year I lost about 20kg of body weight through a combination of diet change and exercise. This apparently give some people the impression that I am very disciplined. I'm not. I do know, however, how to … Continue reading On Discipline: Fooling yourself is an important skill!
During the Specification by Example training I talked about recently, Gojko Adzic introduced me to Effect Mapping. He's writing a more extensive booklet on the subject, of which he's released a beta here. I think this is an excellent tool for exploring goals, opportunities and possible features. It can be used as a tool to … Continue reading On Effect Mapping and Pirate Metrics
Yesterday, after my brother's 47th birthday, I was talking with my father. My father is 79, and he has had an interesting professional life. He started out as a catholic priest but, as you could guess from the fact of my existence, at some point figured out that this was not a sustainable career path … Continue reading Management Innovation, ca. 1972
I've noticed that I very regularly get people visiting my blog through a Google search for the term 'Strategic Inflection Point'. Since that term has some very direct connections to other concepts I've been learning about, I thought I'd give some detail on Strategic Inflection Points, and their relation to the Lean Startup ideas of Pivots and … Continue reading The Strategic Inflection Point as a Special Case Pivot
It's odd how I've been unable to be very consistent in my subject-matter for this blog. I tend to hop around, going from very technical subject to very organisational ones. Some might see this as lacking focus. Maybe that's true. I've never been able to separate execution from organisation and vision very well. To me … Continue reading Turning it up to 11
My esteemed colleague, Ciarán ÓNéill just posted a nice and considered discussion on estimation, velocity and cycle time. I, however, do not plan on being so considered, or considerate. You see, too many people are bent under the crushing weight of living up to estimates. Even reckoning that they provided these estimates to begin with, the … Continue reading Estimates and Commitments – The Hard Truth
A while back I had a little fun comparing Agile to Rock'n'Roll. It's still one of my favourite posts, and after my recent talk on the benefits of TDD, I got the idea that the best follow-up on that is something about the XP practices. Test Driven Development with Bonnie Riatt The first artist that … Continue reading XP is Classic Rock
I recently wrote here about the benefits of failure. One of my recent failures reminded me about the importance of success. I thought that to be nicely circular enough to warrant a new post! You see, while it's important to embrace failure - how else are you going to learn? - it is just as important … Continue reading Success
Last Thursday, Januari 19, I gave a short talk at ArrowsGroup's Agile Evangelists event in Amsterdam. Michiel de Vries was the other speaker, talking about the role of Trust in Agile adoptions. On my recommendation the organisers had changed the format of the evening to include two Open Space Technology sessions, right after each 20 minute talk, with … Continue reading Technical Excellence: Why you should TDD!
Failure is not an option! I've heard that phrase a number of times during my career. Mostly by people imitating a manager they heard in a meeting, but still too often. What's remarkable is that this phrase is usually uttered at the moment that it is becoming very clear that, yes, failure seems to not … Continue reading Failure
