Quality is a goal in a project in addition to cost and time. The quality assurance program of a project functions to ensure that the process during the production period reaches the agreed upon quality targets. The finding of product defects in a building X construction project in Jakarta is the background of this research. The purpose of this study is to identify the quality assurance factors on the product quality performance, analyze the quality assurance factors on the product quality performance, and identify the quality assurance factors that contribute to the product quality performance in a building X construction project in Jakarta. The research methodology was quantitative in nature, starting by identifying the quality assurance factors through a literature study, validating the factors with expert respondents, conducting a survey by distributing questionnaires to respondents, and analyzing the survey results.
