and privacy (1.16%) are also effective in suspended ceiling interface design, while acoustics, durability, hygiene, and fire safety do not play a significant role.

Spatial fit and structural safety are again the most influential requirements, but in this case the percentage of structural safety slightly exceeds that of spatial fit (structural safety 28.95%, spatial fit 2<strong>6.3</strong>2%) (Figure 6.20). When the banded DSMs of two levels of design are compared, it is observed that while the system level DSM consists of 17 bands (Figure 6.16), the assembly level DSM includes only 11 (Figure 6.17). This 3.95
finding supports the comments made above, since more bands mean more critical elements and more coupling in the process. On the other hand, fewer bands suggest that the design is more flexible i.e. the order of design decisions in a band can be safely changed, because they are independent of each other. 152
