| description abstract | Understanding the level of team integration in alliance projects, and how it changes over time, is key to maintaining consistently high levels of integration, and therefore performance, in highly complex projects. In response to the need to integrate teams, the Alliance Team Integration Performance Index (ATIPI), which combines seven weighted key indicators (KIs) and a set of corresponding quantitative measures (QMs) for measuring the team integration in alliance projects, was developed as part of previous research. However, the subjectivity inherent in assessing such performance requires the establishment of well-defined performance scales to ensure consistency and reliability when assessing performance. In order to address this gap in the body of knowledge, 17 recognized experts in the field of project alliancing participated in a questionnaire survey to help develop the performance scales. A systematic procedure based on fuzzy set theory, namely, the modified horizontal approach, was then applied to the survey outputs to establish a range of performance scales for each QM within five levels of performance, namely, | |
