Rewards evaluation model has been suggested by FlanhoItz. It identifies the major variables that determine an individual’s value to an organisation, in other words, his expected reliable value.
The expected realisable value of an individual is the present worth of future services expected to be provided during the period he is expected to remain in the organisation. The model is based on the presumed assumption that a person’s value to an organisation depends upon the positions to be occupied by him in the organisation. The movement of personnel from one organisational role to another can be considered to be a stochasic process with rewards.
In continuation of the above, as people move and occupy different organisational roles, they render services (or, rewards) to the organisation. However, the roles that they occupy in future are determined probabilistically for each individual.
