An Information Explosion
Figure 5 shows
the rate of development of information during the various stages of the project.
Figure 5: The Information Explosion
As you might expect from Figure 3, project
information expands rapidly during the detailed working drawings stage. In fact
it probably grows from about 15% to 85% of the total in this stage. Since this
work is highly dependent upon the quality of the work done in the previous phases
it is vital that these earlier phases deal with all necessary aspects, the information
is of high caliber and, above all, is reasonably firm. Equally, it is vital that
the development of working drawings by all the disciplines involved be managed
and monitored against the approved terms of reference.
