DESCRIPTIVE AND CORRELATION ANALYSIS OF PERFORMANCE INDICATORS: COST, TERM AND RHYTHM

Abstract

The production planning and control process is expanding since it generates benefits that enable the increase in the performance of construction projects. This process contributes so that the main focus of activities is on results, it being necessary to have a set of indicators that relate the company's strategies, action plans and goals. The main objective of this article is to refine the indicators that intend to quantify the effectiveness of planning in civil construction. For that, indicators of Cost, Term and Rhythm Deviations were used and sought to establish relationships between short and long term planning. Four constructions were evaluated in the state of Minas Gerais, carrying out a series of statistical analyzes in the complete work and in pre-divided partial periods based on critical activities that could influence the results. Statistical analyzes were performed considering two types of study: seeking to observe the relationship between the indicators, correlation tests were performed; and in order to characterize the stages according to the indicators, a descriptive statistical analysis was performed. In general, it was found that, as the constructions progressed, the average of the indicators increased, so the stage corresponding to the total duration of the projects presented better results in the descriptive analysis. For the correlation analyzes, the highest degree of association observed was between the Deviations of Term and Rhythm in the stages of 60% and 80%. This result is expected since the higher the rhythm, the better the term.
