Qualitative Analysis for the Diagnosis of the Lean Construction Implementation

Abstract

The paper presents an analysis of the implementation of Lean Construction in the center of Brazil, and an evaluation of the potentialities that each calculation method provides in the diagnosis. The Lean Construction Assessment Tool (LCAT) was used in this research to make critical inferences about the Lean implementation stage in six construction companies in Goiânia, Brazil. Based on the data obtained, the Lean Score was calculated using arithmetic averages, weighted averages and averages based on the Fuzzy Inference System. Based on this analysis, an evaluation of each LCAT criteria was inferred, and its influence on the company's lean score was determined. The advantages and disadvantages of the lean construction implementation process were also evidenced. The measurements obtained presented small variations, such as speed of obtaining the data, interference of other variables in the process, and analysis of specialists. Nevertheless, it was possible to draw conclusions about the different potentialities of the use of each one.

Application of lean management tools in industry 4.0: a systematic review

“…LSS is a methodology that aims to integrate Lean and Six Sigma philosophies, which is a set of practices to systematically improve processes by eliminating defects (Sony, 2020). Lean Construction is a current practice that aims to better reconcile the needs of customers using the least number of resources possible and is also based on the principles of production management (Amaral, Oka & Camargo Filho, 2018).…”
