Investigation of Lean Production Knowledge among Employees in Building Inspection Organizations

Abstract

Currently, lean construction has become very important, with lean manufacturing, a philosophy of production that in the most basic sense refers to the elimination of waste and tries to eliminate anything that does not add value to the product or service, emerging as a Japanese business pattern. The aim of this study was to determine the lean production knowledge among employees in building inspection organizations. To measure the level of awareness in construction inspection institutions, which are the leading entities in the construction sector, and the level of awareness on this issue, a survey was conducted through face-to-face meetings with engineering employees residing in Adana province. The results were converted into datasets in the appropriate Microsoft Excel format. With these datasets, the reliability level of the survey was measured using the SPSS program, and the data were analyzed using WEKA software. The study used association rule learning, a data mining method. According to the results, the number of employees who knew the definition of lean production was less than half, at 47%, while the number of those who knew about the concept of lean construction was 44%. The results obtained according to three different class labels were statistically interpreted, and it was determined that the employees lacked knowledge and sufficient awareness about the subject.
