Abstract: Globalization and the increasing complexity of systems require
collaboration across multidisciplinary teams. Systems Engineering (SE) teams
are often geographically and demographically dispersed; such dispersion might
affect the ability of the teams to produce their desired outcomes. The main objective of this research study was to determine how geographic and
demographic dispersion affect the performance of a SE team, and which phases of
the SE life cycle are more susceptible to positive or negative effects caused
by team dispersion. This research study started with an exhaustive
review of the literature related to team dispersion and team performance. The
next step was building a conceptual model grounded in theory, which allowed the
measurement of geographic and demographic dispersion through the use of
well-established indices recognized by the scientific community. The data
collection process successfully gathered information about projects
geographically distributed throughout 57 cities in 38 countries. Finally, multiple linear regression (MLR) and structural equation modeling
(SEM) were selected as data analysis techniques for this study. The results of
MLR show that geographic and demographic dispersion factors (independent
variables) statistically significantly predicted team performance along each
phase (dependent variables) of the SE life cycle. The results of SEM show a
moderate positive relationship between dispersion and team performance. It was
also found that the SE life cycle phases of Development and Production are the
higher predictors of team performance.
