As the economy increasingly globalizes, skills are becoming the commodity employers trade in. In this skills economy, organizations recognize the importance of growing and attracting talent. A recent study showed that in 2013, businesses in the United States spent approximately $1,200 annually per employee on training, totaling $164.2 billion. Of that figure, 63 percent was spent on internal training and 47 percent was outsourced. A recent study indicated 35 percent of training dollars spent in 2014 went to those who held leadership roles; however, this dynamic is slowly shifting. With advances in technology, it's become more efficient to deliver training, and the cost per training unit is falling, which extends the reach of training programs. Training has also become more flexible. Often it is self-paced, on demand, and personalized, making it easier for all employees to benefit. Training has also become more precise—particular skill sets can be targeted, and a wide variety of analytic tools are available to measure the impact of training over time.
