"Application problems are the single largest source of downtime, causing
30% of annual downtime hours and 32% of downtime cost. The leading
cause of application downtime is software failure (36% of cost on average), followed
by human error (22%)."

"In a new study on network downtime, Infonetics Research found that medium
businesses (101 to 1,000 employees) are losing an average of 1% of their annual
revenue, or $867,000, to downtime.
Applications are the biggest source of downtime, accounting for roughly one-quarter,
or $213,000 annually, split 65/35 between outages and degradations. Focusing on
the source of application outages could save many organizations a significant amount
of money, the report concludes."

"A recent survey by business service management vendor Managed Objects
reveals what might be at the root of network downtime. The company surveyed some
200 US IT managers and senior leaders in June to discover what brings their networks
down and the results show that homegrown applications are behind a majority of downtime
in today's networks.
About 61 percent of survey respondents said applications were behind most of their
network downtime, compared to just 21 percent that reported hardware as the cause.
And nearly 20 percent were uncertain of the cause of downtime at their organisations,
the results found.
Among those surveyed, 82 percent said the application outages and network downtime
in the past year was significant enough to affect their business. Respondents reported
that the average cost of downtime was more than $10,000 per hour and downtime itself
could last an average of three to four hours.
But the most telling results, according to Managed Objects, were those that pointed
to companies supporting more homegrown applications and citing applications as the
cause of network downtime. Homegrown and custom applications can represent up to
90 percent of some organisations' application mix, the vendor says, and more than
80 percent of survey respondents relying more on homegrown applications than off-the-shelf
packaged applications blamed software as the main cause of most outages."

"Finding and fixing a software problem after delivery is often 100 times
more expensive than finding and fixing it during the requirements and design phase.
About 90 percent of the downtime comes from, at most, 10 percent of the defects."
