    A Model for Calculation of a Productivity Bonus por Sánchez de León, José Alfredo

    Publicado 2017
    “…The model takes as inputs the goals and control limits (parameter values of the metrics that are commonly found on many organizations) (Duke, 2013), their value accomplishment result, and a free parameter. A typical real life example is exposed, as a case of study, where it is applied this calculation scheme; as the result, a productivity bonus was successfully calculated, so concluding that this result can be a useful device to carry out this task.…”
