Three typical failure scenarios of the mind process of design from the Axiomatic Design perspective

Review of several failure databases from software, hardware, and service industries and analysis of the failure cases from the Axiomatic Design perspective led to identifying three typical failure scenarios of the mind process of design; uncoupled but unrealized, coupled but over-simplified, and coupled and complex designs. Failure due to coupled and complex design occurred in all databases at rates of 10-40%. Recent large-scale computer systems have especially expanded the number of functional requirements beyond human capability of recognizing their interference, and failure from such causes amounted to 30-40% of all cases of software industry.
