Can you sack your IT department?

"Email is very close to people's hearts and I don't want to cause a revolt in something that is pretty key to people's productivity. That's why I moved first. But you know what, it kind of works," he said.

"Google backs up the email, which is better that most small and medium businesses do which is nothing."

There are still some issues, including syncing contacts onto the BlackBerry, but he says it's "90 per cent there," adding "And I can licence the whole company for $40,000 a year."

Since Burton took over at Serena he's already phased out a lot of traditional IT systems. "We got rid of the marketing system and went to MarketRight. We got rid of the sales system and went to Salesforce, we got rid of the anti-spam and went to Postini, we got rid of big chunks of the intranet and we use Facebook," he details.

"We got rid of the support system. We have eight or nine cloud-based systems and we're going to keep doing it. We do have CRM but we're going to get rid of it for Salesforce. I don't want 50 guys managing infrastructure, I want 50 guys helping us build the company."
