My approach to what I do in my job — and it might even be the approach to my life — is that everything I do is the most important thing I do. Whether it’s a play or the next film. It is the most important thing. I know it’s not going to be the most important thing, and it might not be close to being the best, but I have to make it the most important thing. That means I will be ambitious with my job and not with my career. That’s a very big difference, because if I’m ambitious with my career, everything I do now is just stepping-stones leading to something — a goal I might never reach, and so everything will be disappointing. But if I make everything important, then eventually it will become a career. Big or small, we don’t know. But at least everything was important.
A theory of change is the opposite of a theory of action — it works backwards from the goal, in concrete steps, to figure out what you can do to achieve it. To develop a theory of change, you need to start at the end and repeatedly ask yourself, “Concretely, how does one achieve that?”
On the surface, the world of agile software development is bright, since it is now mainstream. But the reality is troubling, because much of what is done is faux-agile, disregarding agile's values and principles. The three main challenges we should focus on are: fighting the Agile Industrial Complex and its habit of imposing process upon teams, raising the importance of technical excellence, and organizing our teams around products (rather than projects).
It actually doesn't matter whether you actually have a formal retrospective. It doesn't matter whether you have four or five labels of things on your retro board, or exactly how you do the retro. What does matter is the notion of thinking about what we're doing and how we can do better, and it is the team that's doing the work that does this, that is the central thing.
Interestingly, just as software people were talking about how we need to kind of follow this very Taylorist notion as the future of software development, the manufacturing world was moving away from it. The whole notion of what was going on in a lot in manufacturing places was the people doing the work need to have much more of a say in this because they actually see what's happening.
