Porter and Lawler Model of Performance Satisfaction
 
The model explained by Porter and Lawler is a comprehensive 
description of motivation. They have viewed motivation, satisfaction and 
performance as separate variables relating in different ways. According to 
the model, effort, which is the force of motivation, does not directly lead 
to performance but is mediated by abilities, traits and role perceptions, 
followed by rewards and their perceptions. There are four variables in 
the model namely, effort, performance, rewards and satisfaction. 
Effort means the energy exerted by an individual employee for 
performing a given task. The effort depends on the value of reward and 
perceived probability of effort-reward linkage. Efforts mediated by traits 
and abilities and role perception lead to performance. Performance refers

to the results measured objectively. It depends on the effort put up by the 
individual. Rewards are obtained through performance and satisfaction 
is derived. Rewards may be extrinsic, that is in the form of a secondary 
derivative of work, or they could be intrinsic, which are inherent in the 
job itself. Satisfaction is the internal state of being contented depending 
on the rewards received.
