SlideShare, a site for posting and sharing business-related presentations, has perfected the art of constantly tweaking its software and pushing out multiple changes per day based on continuous and exhaustive analysis of user behavior.

SlideShare's CTO and co-founder, Jonathan Boutelle, recommends an approach of constant iteration with respect to software development, based on careful analysis of user behavior. "When you chop work into small enough chunks it becomes much less intimidating," he said.

This approach is much less risky than the conventional philosophy of spending six months or more on a major IT project and then deploying it in full one fine day in a "big bang" manner, he said.

"We don't like big bangs. We like to constantly make small changes and feel that's a great way to reduce risk," he said.

SlideShare is at the point now that it tweaks its Web-based application dozens of times per day. "The combination of having very good measurement of user behavior with the ability to make small changes to the site means we can iterate extremely quickly," he said.
