Original scientific paper Human Resource Management practices (HRM practices) are essential organizational mechanisms to generate, reinforce and sustain the action plan in every organization. The capacity of an action plan depends on the work profile of individuals and teams. This paper proposes a model of HRM practices, with the aim of increasing organizational performance through the development and maintenance over time of the work profile of individuals and teams. This paper shows that by classifying the activities of the model into two blocks, the work performance of the individuals and teams can increase, which subsequently increases and sustains the organizational performance over time. Keywords: HRM practice; performance; strategy and action plan; work profile of individuals and teams Poboljšanje organizacijskih performansi upravljanjem ljudskim resursimaIzvorni znanstveni članak Upravljanje ljudskim resursima u praksi (HRM prakse) je bitan organizacijski mehanizam za generiranje, jačanje i podržavanje akcijskih planova u svakoj organizaciji. Kapacitet akcijskog plana ovisi o radnom profilu pojedinaca i timova. Ovaj članak predlaže model HRM prakse, s ciljem povećanja učinkovitosti organizacije kroz razvoj i održavanje tijekom vremena radnog profila pojedinaca i timova. Ovaj rad pokazuje da klasificiranjem aktivnosti modela u dva bloka, rad i učinkovitost pojedinaca i timova mogu se povećati, čime se potom povećava i održava organizacijska uspješnost tijekom vremena.Ključne riječi: HRM praksa; performanse; pregled radnih profila pojedinaca i timova; strategija i akcijski plan

ABSTRACT

Data envelopment analysis (DEA) is a linear programming methodology aiming to evaluate the relative technical efficiency for each decision making unit (DMU) with multiple inputs and multiple outputs. Each DEA model is formulated as a mathematical programming problem utilizing the values of inputs and outputs of all DMUs. The analytical process is developed on the basis of these inputs and outputs by identifying the best practices in the field. Additionally, DEA can be used as a method to evaluate economic efficiency. In this study, we propose the measurement of public postal operators' profit efficiency by DEA-based profit efficiency approach. In order to demonstrate the applicability of this approach we measured the profit efficiency of public postal operators (PPOs) in the European Union member states and Serbia as a candidate country. The implications are derived from the empirical study by using VRS model, CRS super-efficiency model and Slack-based model. First, we calculated profit efficiency and super-efficiency scores of all observed PPOs. After that, we repeated the analytical process without influential observations. Finally, we determined the target values of inputs and outputs for profit inefficient PPOs.
