INTRODUCTION A model with the purpose of explaining the behavior or the productivity of a worker was constructed at the Engineering Institute of the National Autonomous University of Mexico (II-UNAM). The objectives of this work are: - To obtain a clear causal model that identifies in a simple manner how certain factors relate to yield a productivity level. - To have a model that can be used to simulate the response of the productivity of a worker to different actions. This would help companies in diagnosing the quality of their treatment of human resources and in designing new policies to improve that treatment. - To have a model which helps managers, directors and supervisors in learning the impact of their decisions on the complex phenomenon of the productivity of a worker. In 1978 James C. Hershauer and William A. Ruch (Hershauer and Ruch, 1978) developed at the Arizona State University, a similar model to illustrate the way in which certain factors interact to achieve the productivity level of a worker. This model was considered a novelty and was cited in a good number of publications about productivity. Hershauer and Ruch reported that the model was used at Lincoln Electric as a training tool for supervisors at the production lines and it proved to be valuable in explaining the complexity of the relations that lead to the level of productivity of a worker. In spite of this, the model was never traduced into a program, nor was it used for simulation. The authors considered impossible to measure the factors of human behavior and business management in a
