An incentives rule of thumb

As I was search-engine optimizing the August issue of Corporate Meetings & Incentives, I ran across this little gem:

An incentive program needs to offer a minimum of 3 percent to 5 percent of each participant's annual compensation to get their attention. So an employee who earns $50,000 a year needs at least $1,500 to $3,000 in incentives to drive his or her behavior.
