Contribuições para coleta e análise de indicadores de produtividade em empresas construtoras na cidade de Maceió/AL

Abstract

The implementation of quality systems and performance measurement programs has become an increasing necessity for companies to enhance service quality and customer satisfaction. Performance indicators have played a significant role in the development of the construction industry and the reduction of market barriers, as they assist companies in meeting expectations regarding project costs and deadlines. The effects of implementing indicators can be enhanced when combined with benchmarking practices, which, despite being a less frequently performed activity in Alagoas, have shown significant returns for construction companies in Brazil and worldwide. In light of this scenario, the Research Group in Construction Management and Economics at the Federal University of Alagoas, in partnership with the Association of Real Estate Companies in Alagoas and eleven active construction companies in the state, implemented performance indicators. Considering the author's participation in this research project, this work aims to propose contributions to the collection and analysis of productivity indicator data based on the results of statistical analyses. The method employed was file analysis using materials provided by the Group, and a systematic literature review was conducted to support this work. The z-test for two samples, Kolmogorov-Smirnov test, and Central Limit Theorem tests were utilized, employing GNU Octave software to verify normality. Among the seven services analyzed, five demonstrated increased productivity. Among the main conclusions, the study indicated statistically significant evidence of increased productivity for the companies over the three analyzed years, as a result of implementing indicators associated with benchmarking practices. However, difficulties in standardizing data collection and storage still significantly affect the analysis of results.
