Abstract

Impacts defects have on customer satisfaction are hard to quantify, but they should not be ignored because of poor understanding of the intangible costs related to quality may lead to poor decision-making. However, data about building defects and customer satisfaction surveys are not usually analyzed together. This study used a database of the technical assistance department in a Brazilian construction company and results from their customer satisfaction surveys. The study seeks to address the lack of in-depth analysis of issues concerning customer satisfaction and defects, and how they are related. By cross-analyzing data from the defects database and the customer satisfaction surveys, on a unit-by-unit basis, relationships between the occurrence of defects, the customer perception of these defects, and the impact they have in customer satisfaction were found. Results revealed that some customers can be dissatisfied with the building quality and are still satisfied with the project, which indicates that the overall satisfaction is a complex variable that is related to a number of features. Moreover, the occurrence of defects did not seem to impact the customer satisfaction negatively if defects were fixed under the warranty period, and the non-occurrence of defects had a positive impact on the customer satisfaction.
