## 6 Findings--Analysis of Correlation between Career Characteristics and Competency Level
### Analysis of Correlation between Career Characteristics and Competency Level in Knowledge' Domain
#### 6.1.2 Analysis of the Designer Group  
Table 8 shows the correlation between the career characteristics and the 'Knowledge' domain-specific competencies of the designer group. Among the career characteristics, 'Overall project experiences', and 'BIM-based construction project experience' were found to have correlations with most specific competency items within the 'Knowledge' domain. Correlation is significant at the 0.01 level (2-tailed). \begin{table}

Table 7: Analysis of correlation between ‘Knowledge’ domain competencies and career characteristics of the owner group. As was the case of the owner group, a clear correlation was found within the designer group between the 'Overall project experiences' career characteristic and certain competencies, such as 'Supply management' and 'Cost management', pertaining to the 'Construction related knowledge' competency group. In addition, significant correlations were found between the same career characteristic ('Overall project experiences') and certain specific competencies, such as 'Construction licensing standard', 'Schedule management', and 'LOD definition'.
