Similarities:
For Maslow & Herzberg
Both theories do not take into account diversity amongst workers in the structure of the theory.
Both theories are hierarchal, where the bottom level must be met before the above levels can be satisfied to the fullest
Herzberg & Lockes
Both Herzberg and Locke uses theories based on achievement and recognition of employee goals
The work itself is a main motivational factor of both goals
Feedback is required to motivate employees to work more productively
The theory is two-way, meaning employees are more likely to negotiate tasks with the manager and are also more likely to be motivated to achieve them.
Maslow & Lockes
Both theories establish relationships and feedback is constant to continue motivating employees to work hard. They are motivators in both instances (however in Maslow’s theory, recognition and feedback is at a later stage of an employee’s career.)
