dc.description.abstract | Why do Koskela and others argue that the underlying theory of project management (PM)
is obsolete? Project management works for the manufacturing industry, and for the
construction industry at both the physical production level and the subcontractor level.
Stakeholders, including the owner (along with due diligence, and O&M teams), architect
(and the design team), general contractor (and its subcontractor team) create, transmit,
process, manage and use information. The boundary between information (creation and
transmission) and physical production is where PM controls and predicts cost and schedule
and where quality controls fail to work as intended. This paper argues that subcontractors
give project numbers for the physical part of the project, while general contractors
’
project
numbers are actually a
project of projects
(those of the subcontractors). The general
contractor manages a meta-project (term and de
fi
nition, as related to building construction,
coined by Fernandez-Solis). The meta-project paradigm has signi
fi
cant consequences and is
the key to a novel understanding of the general contractor role. Lean construction
’
s percent
(or promise) plan complete (PPC) gages the reliability of promises made, is a useful and
viable indicator of the quality of the schedule, and serves as a surrogate measure of project
fl
ow
–
how smoothly or chaotically a project runs. The PPC is operationalized as an index
that meta-project stakeholders can use to calibrate the reliability of work in progress and
provide feedback on the predictability/variability of logistic plans. The methodology of this
paper uses conceptual analysis, the metonymic mapping of key concepts from the
thermodynamics domain to the construction domain and showcases the concepts through
PPC case studies. Information entropy theories are discerned in the PPC reports. In
conclusion, scienti
fi
c information theories, principles and characteristics of
fl
ow, in contrast
to managerial principles, provide a clearer background for visualizing a novel understanding
of the state of the project
fl
ow at the meta-project level. It could be argued that this paper is
about de
fi
ning a reference discipline and construed as
“
construction science viewed through
the lens of entropy
”
but this is not the focus of this paper but the topic of the next. | en |
