E-mail boosts productivity; IM poses threats, survey says

When it comes to communicating during the workday, a majority of enterprise users find e-mail and phone calls conducive to productivity, while unified communications technologies such as instant messaging, blogs and softphones distract them from the work at hand and pose a threat to enterprise security.

IT consulting firm Dimension Data Holdings PLC surveyed some 524 IT managers and enterprise end users to learn which means of communications improved productivity and which had the opposite effect. According to the findings, more than 70% of users said e-mail helps productivity, followed by fixed-line telephony at 53% and mobile telephony at 52%. One hundred percent of respondents said they use e-mail, while 80% use the telephone, and another 76% rely upon their mobile phones.

"Consistent with my own research, there is a strong correlation between asynchronous communication, like e-mail, and multitasking," said Marshall Van Alstyne, professor of information systems economics at Boston University and MIT, in a Dimension Data press release. "Although users may take more time to complete individual projects, they are actually finishing a greater number of tasks. E-mail does not speed work in all cases, but rather, its advantage is to help people juggle projects and multitask more effectively. This increases project completion rates."

And while 66% of enterprise end users also reported that they use instant messaging to communicate at work, respondents also indicated the unified communications application had the most potential to cause a breach, along with PDAs and mobile phones. IDC estimates that the market for unified communications will grow to $17.5 billion by 2011, but Dimension Data warns IT managers and enterprise users must be aware of the security threats posed by such applications.

For instance, 52% of users said they perceived unified communications to be as secure as other information and communications technologies, but just 31% of IT managers agreed that the technologies were equally secure. In fact, 16% of IT managers said they believed the technology to be moderately risky, and close to 10% think instant messaging is very risky. Some of the risks identified by Dimension Data include fraud and identity theft that could lead to the unauthorized use of enterprise services, and denial-of-service and other disguised attacks using less-secure applications as a means of entry.

"This result indicates that IT managers are aware of the new risk types that are associated with unified communications, while IT users are probably reasonably unaware of the risks they might be exposed to and expose their organizations to when using communications technologies other than e-mail," the report said.
