Comprehensiveness is the enemy of comprehensibility.

I can't choose whether someone is offended by my actions. I can choose whether I care.

In almost all cases, I’m opposed to setting aside time for refactoring. In my view refactoring is not an activity you set aside time to do. Refactoring is something you do all the time in little bursts.

The biggest issue on software teams is making sure everyone understands what everyone else is doing.

Why is composing symphonies tough? I don't know. It's just very few people in the world can do it well. And I think that's the case with upfront design. It is very hard to do well.

So I hope I’ve made clear that imposing agile methods is a very red flag.

When you actually sit down to write some code, you learn things that you didn't get from thinking about them in modeling terms...there is a feedback process there that you can only really get at from executing some things and seeing what works
