Discuss the challenge of generating long-term behavioral improvement.

Do incentive plans improve performance for only a brief window of time?
What kinds of changes can they cause in the culture of an organization?
If incentive programs are for only a limited period of time, are there any extended benefits?
When incentive programs are over, will employees return to their old behaviors or (even worse) begrudge the company for the lack of extra pay (even if there is no

quantifiable improvement to justify it)?
