In a surprise victory, Spike Solutions won the poll for this week's excerpt from The Art of Agile Development. I'm surprised because it was tied with Simple Design and Refactoring right up until the end, and those are much more fundamental practices. But Spike Solutions is a nice little practice, and it's a quick read.

Here are the full results:

• Incremental Requirements - 10%
• Customer Tests - 14%
• Refactoring - 19%
• Simple Design - 19%
• Spike Solutions - 24%
• Performance Optimization - 10%
• Exploratory Testing - 5%

Next week's practice comes from the Thinking chapter (poll here). The following week's excerpt is scheduled to come from the Collaborating chapter. Which one should I put up next?
