The surge of millennials in the US workforce is reshaping business environments and driving IT departments to adapt their infrastructures with millennial-friendly technologies, including mobility, cloud, big data and social media, according to a new study by Randstad Technologies and IDG Research Services.

While the survey found two-thirds of IT leaders say they have or are formulating a plan to address millennials’ technology needs, one-third of respondents reported they have not addressed millennial-related technology issues in any formal way.

“Millennials have grown up in a digital society with technology touching almost every aspect of their lives,” said Bob Dickey, group president of technology and engineering, Randstad Technologies. “As a result, millennials want to have the same technological capabilities in the workplace as they have in their personal lives. To attract and retain millennial talent, IT leaders need to rapidly adopt current and forward-thinking technologies into their infrastructures. Organizations that are unable to support millennials’ IT needs may see greater turnover and experience more difficulty recruiting top talent from this demographic of the workforce.”

More than three-fourths, 78%, of respondents reported an increase in their organization’s mobile/remote workforce and 70% of respondents selected “mobility” as a technology needed to support the millennial shift. Additionally, 60% of IT leaders surveyed plan to increase investments in mobile within the next year.

More than half, 57%, of respondents viewed communication and collaboration tools as essential to supporting the millennial shift, and 43% plan to place more investments in these technologies.

The survey also found 80% of organizations expect to outsource portions of IT project to an external service provider, and 70% expect to outsource large IT project to an external services provider who can provide full turn-key delivery of required outcomes.

Only 22% of respondents use integrated technologies to centralize learning content and knowledge transfer, and of those who have yet to develop centralized knowledge transfer, 42% reported they already are or will be addressing the issue in the next 12 months.

“Our survey found that to effectively change their technology infrastructure, IT departments need employees who are skilled in security, data analytics, cloud and data integration,” Dickey said. ”Because of the current IT skills shortage, companies often outsource projects to service providers and contractors so they can consistently maintain current technologies and ultimately help attract the best talent to their organizations.”

IDG Research Services conducted the online survey from Oct. 31 to Nov.11, 2014 with 134 qualified completes. Respondents held specific IT job titles and were part of 1,000-plus employee organizations that have been impacted by the “millennial shift” in the workplace to some extent.
