Abstract:
Performance inefficiency is a critical challenge facing the
construction industry. Despite the efforts made in the existing
body of literature, an integrated theory of performance
assessment facilitating a bottom-up understanding of the
dynamic behaviors, uncertainties, and interdependencies
between the constituents in construction projects is still
missing. The traditional paradigm for performance assessment z
is mainly based on a reductionism perspective, in which
construction projects are identified as monolithic systems.
However, complex construction projects are systems-of-systems.
Systems-of-systems have unique traits that are different
from those of monolithic systems. Failure to investigate construction
projects as systems-of-systems has led to theoretical
and methodological limitations in the creation of integrated
tools and techniques for better assessment of performance in
complex construction projects. To address these theoretical
and methodological limitations, a system-of-systems framework
is proposed as a theoretical lens and methodological
structure toward creation of tools and techniques for integrated
performance assessment of complex construction projects.
Two principles (i.e., base-level abstraction and multi-level
aggregation) are used to develop the proposed framework.
The proposed framework facilitates a bottom-up evaluation
of the dynamic behaviors, uncertainties, and interdependencies
between the constituents in construction projects. The
capabilizties of the proposed framework show its potential in
addressing the limitations pertaining to the traditional frameworks
for performance assessment. Hence, it can be adopted
and tested by researchers to advance the body of knowledge
and create integrated theories of performance assessment in
complex construction projects.
