“[CAST’s] holistic system approach, looking at the architecture, transactions, control, and data flow across multiple

technologies, may be very beneficial, with numerous engineering studies showing that bad software engineering practices

in the ways components are interrelated and interact…account for only 10% of total defects, but can lead to 90% of

production issues.
