What is McClellands achievement motivation theory?

According to this theory, the following three needs motivate people:

• Achievement - This is the need to perform well, achieve success, and get recognized for it. The key idea here is the drive to Excel.

• Affiliation - This is the need or desire for good relationships at work. You want to feel connected at work.

• Power - This is the desire to move things, to influence people or events. The key term here is the world dominance or making a difference.
