The focus of this article is on life-cycle objective-based project manageme
nt models in general. The model has been designed (1) to facilitate employm
ent of life-cycle objective-based project management approaches and (2) to
support concurrent engineering and construction, thus promoting greater int
egration of total processes under which projects are proposed and implement
ed. In order to synthesize rite functions designed in the model, we underto
ok a detailed case study of a large capital project. This case study has be
en documented in separate articles; only the results of the study,will be p
resented in this article. while this field research shed light on the actua
l needs and requirements, the design of the fucntions was approached from f
irst principles. They incorporate the basic shift from the traditional obje
ctives Of cost, time, and quality to life-cycle objective functions, such a
s return on investment, facility operability, and life-cycle integration. T
his article describes the fundamental philosophy and framework for the deve
lopment of life-cycle project management in general and contrasts this with
the traditional project management models.
