Motivation is Psychology drive to achieve goals.
There are many theories of motivation that can be combined then the capacity of each theory will predict the reality of people 's behaviour in work environment.
Katzell and Thompson developed in 1990 a comprehensive theoretical model of work attitudes, motivation, and performance based on a key constructs prevalent in more limited theories. The constructs were selected on the basis of their importance as shown by past researches and because of their complementarities. The framework connects the constructs causally on the basis of both logic and empirical evidence. It is expressed in the form of a path diagram suitable for empirical test. It is expected that such an integrative framework will provide a better basis for understanding and improving work attitudes, motivation, and performance than do the more limited approaches
Katzell and Thompson organize the different variables from many theories of motivation in to one single framework and link them. This integrative model of motivation provides a good level of representation of an organisation 's structure and the advantage of this framework is that it can be used as an instrument to evaluate the motivation level in an organization
Before analyzing the linkage between these variables, I will describe each of them;
Personal dispositions: It is what each individual bring with him/her in a work environment, such as motivation, needs, values/interest ( Maslow 's theory)
Work environment: all the characteristic of the work, in particular in the work place, which can react positively or negatively, for example: management practices, material resources, work condition, method to fix objectives, method to supervise and identify/design the task.
Incentive or reward; it can be rewards (monetary or
