maslow uses a hierarchical theory with the least important needs (basic pay) at the bottom ascending to the most important needs (challenging and creative work) at the stop. Employees have to fill one level of need before moving to the next and once a need is filled then it is no longer effective at motivating them.
Herzberg is the 2-factor theory which comprises the motivation factors like recognition, challenging work) and hygiene factors (pay, suitable working conditions). The hygiene factors will provide a level of satisfaction but no motivation.
Locke is a goal-setting theory where he believed employees would be more motivated when they set goals and achieve them while being recognised and having feedback given to them by managers. The goals set have to be SMART (specific, measurable, achievable, relevant, time-bound) in order to motivate employees. Locke's theory also relies on participation between managers and employees to communicate and set goals. Managers can use management by objectives where they set specific, measurable goals with employees and review their performance.
