Conceptual Integrity

As mentioned in The Mythical Man Month, good system design (user friendly) requires a small (ideally singular) team of architects, separated from implementation, that decide what goes into the system and what stays out. This avoids rogue ideas making it in that muddy the overall product.

In No Silver Bullets, Fred Brooks adds that conceptual integrity is difficult to achieve because of the inherent complexity of software systems—complexities can not be ignored as one would a simplified model in mathematics or physics because the complexities are the essence.
