Human resources executives have money to invest in technology, they just don't know what to invest in. That's according to online benefits-solutions provider RewardsPlus, Baltimore, which found that 55.6% of the 291 human resources executives it surveyed said their biggest challenge is discerning which technology will meet their increasing scope of responsibility. Only 21.4% said cost of the technology was a concern. In addition, 16.3% said their biggest professional challenge is managing corporate growth and change. This is a dramatic shift from the conventional role of human resources managers as mere benefits administrators, according to RewardsPlus. "The nature of this job is changing from tactical to strategic," says Ken Barksdale, president and COO of RewardsPlus. "We're clearly seeing corporate resolve to fund the technology necessary to support this role shift, but we're also seeing a great deal of concern about which technologies to adopt."
