U.S. companies spend over $70 billion annually on training, and an average of $1,459 per salesperson — almost 20 percent more than they spend on workers in all other functions. Yet, when it comes to equipping sales teams with relevant knowledge and skills, the ROI of sales training is disappointing. Studies indicate that participants in traditional curriculum-based training forget more than 80 percent of the information they were taught within 90 days.
