One of the most pervasive debates about managing people is whether using “hard” or “soft” approaches produces better performance. Hard approaches seek to influence behavior by pressuring people to do things they would not have freely chosen to do. Soft ones seek to influence behavior by nurturing people to build a commitment to doing a good job.
