Diagnosing the Causes of Poor Quality Management in Iraqi Construction Projects Using Technique of Root Cause Analysis

Abstract

The objective of this research is to classify and diagnose the causes of poor quality management in Iraqi construction projects. This study diagnosed fifty-three causes of poor quality management in Iraqi construction Projects. which they divided into eight main groups (Equipment causes, Labors causes, Systems causes, Materials causes, Design and Execution causes, Subcontractors causes, Site staff causes, Contract causes). Then calculated the relative importance of the causes of poor quality management in Iraqi construction projects. Three techniques were used in this study: Ishikawa diagrams, Pareto diagrams, and 5-why techniques. Pareto analysis showed that thirty-six causes out of fifty-three causes represent the most important causes of poor Quality Management, these causes had been filtered by 5-Why analysis. The most important causes were failure to comply with laws and standards and poor compliance to specification, as identified in contract conditions within design and execution causes group, followed by low skill and experience of Contractor’s staff within Site staff causes group and failure to implement a quality control and assurance system within systems causes group.
