A plan is an example of what could happen, not a prediction of what will happen.
I’m not a great programmer; I’m just a good programmer with great habits.
I don’t like the feeling, but I’ve got to say that a little fear makes me a more focused, more responsible programmer.
I’ve known people who have not mastered their tools who are good programmers, but not a tool master who remained a mediocre programmer.
The business changes. The technology changes. The team changes. The team members change. The problem isn’t change, per se, because change is going to happen; the problem, rather, is the inability to cope with change when it comes.
Responsible Development is the style of development I aspire to now. It can be summarized by answering the question, How would I develop if it were my money? I’m amazed how many theoretical arguments evaporate when faced with this question.
I tell people to start implementing when they are pretty sure there aren’t more important stories out there. An iteration’s worth of data is worth months of speculation.
How good the design is doesn’t matter near as much as whether the design is getting better or worse. If it is getting better, day by day, I can live with it forever. If it is getting worse, I will die.
If testing costs more than not testing, then don’t test.
Make it work, make it right, make it fast.
Of the four project development variables – scope, cost, time and quality – quality isn’t really a free variable. The only possible values are “excellent” and “insanely excellent”, depending on whether lives are at stake.
The system metaphor is a story that everyone – customers, programmers, and managers – can tell about how the system works.
Optimism is an occupational hazard of programming; feedback is the treatment.
Sometimes the problem has to mature before the solution can mature.
Listening, Testing, Coding, Designing. That’s all there is to software. Anyone who tells you different is selling something.
Testing is not the point. The point is about responsibility.
Learning research tells us that the time lag from experiment to feedback is critical...
The community isn’t nearly as afraid as it thinks it is.
If you’re having trouble succeeding, fail.
I mean, source code in files; how quaint, how seventies!
