The primary goal of this research is to provide quantitative information used for the implementation of project management attributes. Nineteen project management attributes and five project performance outcomes were investigated to examine their relationships. A series of statistical analyses were conducted to quantify the relationships between the implementation levels of the attributes and the probabilities for better project performance. The analyses utilized data from 212 projects collected by the Construction Industry Institute (CII) Benchmarking and Metric database from 2007 through 2010. The results showed that the beneficial effects of project management attributes varied depending on the implementation levels of project management attributes, the performance outcome type, and whether the project was conducted by the owner or contractor organization. Quantified analysis results were provided by this research. Project management attributes were identified as critical if they were found to be significantly related to a particular performance outcome. Minimum implementation levels were provided for these critical attributes, as were results covering the combined effects of the critical attributes on performance outcomes. Based on the analysis results, the research generated specific and quantitative information used in implementing project management attributes for better performance. This information will help practitioners achieve improved project performance in the most effective and efficient way, and thus it is the practical contribution of this research. From an academic point of view, this study designed a data analysis process by a series of statistical analysis methods which makes it possible to examine the relationships between project management attributes and various project performance outcomes in a quantitative manner. / text
