Complex VS Complicated Systems Complicated System: Large number of highly connected components. Components have well-defined roles and are governed by prescribed interactions. Structure remains stable over the time. Low dynamical behavior. No adaptation.One key defect may bring the system to a halt. Limited range of responses to changes in their environment. Decomposing the system and analyzing sub-parts can give us an understanding of the behavior of the whole,i.e.the whole can be reassembled from its parts. Problems can be solved through analytical thinking and diligence work. System Engineering by J.J.Gao CLGO 9

Example of Complicated Systems Star Caliber Patek Phillipe mechanical watch. We understand: how it is constructed, the required tolerances, the order of assembly. Each component works in unison to accomplish a global function: keep time precisely. We can take a reductionist path to define the smallest required parts and can further write equations of motion to predict the performance and functionality of the watch.
