1.3.1: System Reliability
Assuring System Reliability Other Information:
The IT systems that uphold infrastructure and corporate activities consist of various software combinations. A reliable system
structure is crucial, but simply building a system with reliable software does not necessarily ensure the system itself is
reliable. In fact, only 30% of system failures are caused by software defects and the majority reasons lie elsewhere. Therefore,
IPA strives to improve overall system reliability and software reliability, establish procedures that can be implemented early
on in the planning and system maintenance stages, systemize design procedures (technology) for greater reliability, and nurture
engineers proficient in these technologies. Today, networks are becoming more advanced; we can easily access the Internet
from our mobile phones, and even our household appliances. IT systems are also evolving into complex integrated systems, which
connect an infinite number of embedded software and information network systems. While mutual connectivity creates new worth,
the safety of the entire system is not guaranteed no matter how reliable the individual products or software are. These are
the kinds of new issues that IPA investigates.
