The distribution/mixture of the professionals and organisations involved in this study are shown in Tables 1 and 2. The largest proportion of the participants was for civil engineers (34%). In addition, more than half of the respondents (63%) were from practitioners holding managerial positions and with more than 10 years of experience in the industry.

Research Results and Analysis
Techniques used by construction organisations for performance measurement
A range of measurements developed to evaluate project performance were identified from literature and introduced to a question, in order to allow the study to identify the most common techniques used by construction organisations for performance measurement. The responses revealed that result-oriented KPIs are the most common technique used amongst construction organisations for performance measurement. It was also found that many organisations still rely heavily on the experience of their managers as means for performance measurement (Figure 1).
