Preproject planning is defined as the process of developing sufficient
strategic information for owners to address risk and decide whether t
o commit resources to maximize the change for a successful capital fac
ility project. Preproject planning-also known as feasibility analysis,
conceptual planning, and front-end planning-is at the interface betwe
en business and engineering. It is an owner's responsibility that it b
e performed adequately; however, many preproject-planning functions ar
e performed by engineering consultants. Members of the engineering pro
fession must be aware of its implications and requirements. This artic
le presents results from an on-going investigation of preproject plann
ing. The concept and definition of preproject planning are discussed.
A validated process map describing the major subprocesses of preprojec
t planning is presented and a brief narrative describing each is given
. Key preproject-planning principles discovered during the course of t
he research project are outlined and conclusions concerning the prepro
ject planning process are presented.
