Monitoring work efficiency and employee motivation is an extremely important segment of every organization's business. By comparing theoretical models and through comparison with an example from practice, we get an insight into the complexity of the mentioned issue. The work is divided into two parts. The first part of the paper is an overview in which a cross-section of the literature related to motivating and monitoring the work efficiency of employees is presented. Human resources management can be reduced to four functions, namely planning, organizing, managing and controlling. All four functions are interconnected and essential in the achievement of organizational goals, for which the role of the manager is very important. In this process, the manager can apply different leadership styles and performance measurement methods, and in order to successfully achieve the organization's goals, manager should apply the method that leads to the best results at that moment. Given that achieving goals requires people who will do the work, it is important to create a stimulating work environment and understand what motivates them, because a demotivated employee is also less productive. In motivating employees, managers have material and non-material forms of motivation at their disposal, and praise for someone's work is often sufficient motivation. The importance of employee motivation, the establishment of an employee monitoring system, the role of different leadership styles, the importance of feedback and the ways in which good feedback is given are analyzed. The second part of the paper is a case study in descriptive form that follows the steps in the process of introducing a work efficiency system in a real organization, i.e. the process of monitoring the work performance of employees. After the analyzes are carried out, it is concluded that the example from practice, when introducing the model through different time stages and with modifications, according to its needs, follows the models mentioned in the contemporary literature.
