Then there are the unexpected twists and turns. For instance, let's say a company institutes a BYOD smartphone mandate. One of the employees has a poor credit rating and can't obtain a phone with enough data and minutes to do his job. Does this impact his future with the company? By having to disclose his poor credit rating, was his privacy violated?
BYOD is wrought with these kinds of complex issues and hidden costs. Unfortunately, too many companies jump on the BYOD bandwagon without proper planning, only to get a reality check on their balance sheets.
"Companies that are not really getting out in front of this, it's kind of embarrassing," Schofield says. "They're not seeing cost reduction, they're seeing cost transfer to other areas. And in some cases, it's going up."
