Abstract: On
the base of analyzing the time features of competition in manufacturing,
a proposition on modern design theory and methodology is suggested.
Several Internet-based collaborative design projects are practicing by a
group in China. Theoretical investigation is carried out concurrently
and presented. It is clear that existed results of design theory dealt
with only pieces of the topic in design and cannot control a whole
design process, especially in front of the daily increasing pressure on
product innovation from market and the trend of intelligent resource
varying from a vertical structure to a horizontal structure. The results
of investigation show that modern design theory is in principle
consisted of four parts: theory of the design process, theory of
performance needs driving, theory of knowledge flow and theory of
working in line between stakeholders. The basic frameworks for the
theories are introduced and possible methods relative to the theories
are discussed. Besides parts of the first two, most contents of the
theories have not been studies or are just been recognized. Therefore
there is a very wide space, in which the modern design theory and
methodology can be developed. It is argued that good design methods can
be studied and established only under the guide of perfect theories, and
good design tools (including software) must be studied and developed
only for realizing the good design methods. Those viewpoints considering
that advanced software can be developed independent with the study of
modern design theory and methodology cannot be accepted. Tools produced
under the guide of theory and methodology out of date will be of low
efficiency or sometimes become the obstacles of advancement of design.
Key words: Modern
design Design theory and methodology Performance needs Knowledge flow
