side indicating the scheduled start and finish dates for each task. Charts
are easy to prepare and use, but their best applications are limited to
short design projects with few participants and little interrelationship
between activities since, they are incapable of representing the
interrelationships.
3.4 Shortcomings of Current Building Design
Process Models
Having analyzed the most widely used process modeling methods in
the AEC industry, the following deficiencies are observed:
1. The complexity of design processes entails detailed analyses to gain
insight into process structures. However, current process models
used in the industry have a top-down approach including very little
information about interrelationships at lower levels. Of course, one of
the reasons why many process models fail to represent the detailed
process is because of the intricacy it adds. Graphical models
become so tangled as the process is represented at lower levels that
the descriptiveness of the tools diminishes. The DSM method works
well in such situations, since it is a compact, visual and analytically
advantageous format for complex systems.
The developments in the computer technology also support building
and manipulating detailed models. When standardization efforts
were begun in building product modeling in 1980s, the focus was on
general systems models. As the field is more matured, the models
