Project life cycles

Most, if not all, projects go through a life cycle which varies with the size and complexity of the project. On medium to large projects the life cycle will generally follow the pattern which has been set out in BS 6079. This is Basic ideas, business case, statement of requirements, scope Tests for technical, commercial and financial viability, technical studies, Application for funds, stating risks, options, TCQ criteria Approvals, permits, conditions, project strategy Development design,...

History

The development of network analysis techniques more or less coincided with that of the digital computer. The early network analysis programs were, therefore, limited by the storage and processing capacity of the computer as well as the input and output facilities. The techniques employed mainly involved producing punched cards (one card for each activity) and feeding them into the machine via a card reader. These procedures were time consuming and tedious, and, because the punching of the cards...

Work breakdown structures

An examination of the project life cycle diagram will show that each phase can be regarded as a project in its own right, although each will be of very different size and complexity. For example, when a company is considering developing a new oil field, the feasibility study phase could be of considerable size although the main project would cover the design, development and production phases. To be able to control such a project, the phase must be broken down further into stages or tasks,...
