It was a very specific situation but one of the most creative is a levels program. But instead of just seeing where sales reps ended up, the reps were asked to choose the level they were shooting for. The trick was that regardless of final sales, they could not move up a level AND they could not slip back more than one level or they earned nothing. The sales manager was amazed by how many chose levels higher than the manager would have assigned them AND most hit their goal!
