Hennessy sees bolstering a company against unforeseen incidents as directly tied to business growth.

"You can't put a price on business continuity," he said. "The key thing is you need to focus on business productivity and building a growing company. It may cost resources and dollars to do the right thing and spend the dollars and make the investments up front. It's an insurance policy that you've just got to pay."

Ruckus, which has employees in 22 countries, to minimize the chances of one incident jeopardizing the entire company's ability to function. The decision to move e-mail to the cloud paid off last year when employees were able to access e-mail after a six-hour power outage in the San Francisco area left Ruckus' Sunnyvale, California, headquarters dark.

"We want to make sure if there is a localized power outage, or localized earthquake, or local disaster here, it doesn't take down the rest of the world," said Hennessy.

Business continuity planning also means determining what parts of the company to prioritize when determining how to spend money. Hennessy followed his heart to figure where to invest.
