Motivation is the internal process leading to behavior to satisfy needs. Performance is determined by the formula: Performance = Ability x Motivation x Resources. There are several theories of motivation including: content theories like Maslow's hierarchy of needs and ERG theory that focus on identifying people's needs; process theories like expectancy theory that examine how motivation works; and reinforcement theories based on positive and negative consequences influencing behavior. Effective motivation techniques include setting objectives, job enrichment, praise, and management by objectives. Cross-cultural differences also impact motivation.
