Ward Cunningham quotes
Ward Cunningham is an American computer programmer, best known for creating the first wiki. His work has had a profound impact on online collaboration and knowledge sharing. He pioneered concepts that now underpin many modern collaborative platforms. Here are 78 of his quotes:
Traditionally, the cost of change curve said that if we detect the need for a change early, it costs less to make the change than if we detect the need late. I tackled that curve by saying, let's almost intentionally make mistakes so we can practice correcting them. That practice will help reduce the cost of making changes late.
Our feeling was that the limiting factor on any change was not when it was done, but how much thinking was required.

Wiki has a feel of brainstorming, though it's not as interactive. You can do 10 minutes of brainstorming, and 30 minutes of analysis of the product of that brainstorming, and have something in 45 minutes. The pace on wiki is slower. You could write a page about an idea, or maybe a page about a bunch of ideas. Then you could come back in a week and see what's developed on that page.

I like the notion of working the program, like an artist works a lump of clay. An artist wants to make a sculpture, but before she makes the sculpture, she just massages the clay. She starts towards making the sculpture, and sees what the clay wants to do. And the more she handles the clay, the more the clay tends to do what she wants. It becomes compliant to her will.
A development team works on a piece of code over several months. Initially, they make a piece of code, and it's a little stiff. It's small, but it's still stiff. Then they move the code, and it gets a little easier to move.

So today, let's write a program simply. But let's also realize that tomorrow, we're going to make it more complex, because tomorrow it's going to do more. So we'll take that simplicity and we'll lose some of it. But tomorrow, hopefully tomorrow's program is as simple as possible for tomorrow's needs. Hopefully we'll preserve simplicity as the program grows.

You don't want to write a big comment that tells others how to make a change they might want to make, because you don't know what change they're going to want to make. Better to have the attitude that you can't help future programmers make their changes. All you can do is make it easy for them to understand what you were trying to do. And it will be easiest for them to understand what you were trying to do if you were very careful to not try to do too much.

In the months before I made wiki, we had been having an argument. I think Kent Beck and I were on one side. People who had a lot of faith in the prevailing dogma of software engineering were on the other side. We said, "Collective code ownership is good." They said, "That's ridiculous. You'll never get responsibility. You'll never get quality if you don't have responsibility. And the only way you'll get responsibility is ownership. You have to pin the bugs back on somebody if you want them to ever rise above producing bugs."

Often, the program ends up amazing. You'll say, "This is beautifully architected." Well, where did that architecture come from?
In this case, architecture means the systematic way we deal with diverse requirements. Architecture allows us, when we go to do work we need to do on the program, to find where things go. It is a system that was worked into the program by all the little decisions we made - little decisions that were right, and little decisions that were wrong and corrected. In a sense we get the architecture without really trying. All the decisions in the context of the other decisions simply gel into an architecture.
