http://blog.castsoftware.com/modernize-qa-with-automated-structural-quality-gates/ Unlike a code-level bug, a system level defect involves interactions between several components, often spread across different levels of an application, making it more difficult to find and fix. And even though these types of violations only account for 10 percent of the total number of defects, they lead to ninety percent of the production issues — severely impacting software quality and technical debt.

“[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.
