Tech experts: Better to just start over from scratch on ObamaCare website

“We don’t even know where all of the problems lie, so how can we solve them?” Bhalla said. “It’s like a drive-by shooting: You’re going fast and you might hit it, you might miss it. But you can’t fix what you can’t identify.”

Several computer engineers said it would likely be easier to rebuild Healthcare.gov than to fix the issues in the current system. But it’s unlikely that the government would toss out a reported $640 million worth of work.

The sheer size of Healthcare.gov is indicative of a major rush job. Rolling the site out too quickly likely increased the number of errors, and that makes the fixes more difficult to implement.

“Projects that are done rapidly usually have a lot of [repetitive] code,” said Arron Kallenberg, a software engineer and tech entrepreneur. “So when you have a problem, instead of debugging something in a single location, you’re tracking it down all through the code base.”
