SUMMARY
Figure 2: Problem-solving techniques in various situations.
Through the analysis with respect to the four variables it is found that the problem
of changing the present way of interpreting the construction industry can be characterized
as:
An open system with complex problems where the implications have a long
range and there is a low control on variables.
According to Richard Duke this implies the possible problem solving techniques
indicated in Figure 3.
Short range Implications Long range
