High Availability dollars

According to BMC, for every $1 spent buying infrastructure, their customers say it costs another $3 to manage it.

They also say that 80 percent of downtime is caused by mis-configuration or operator mistakes.

Think about it. Let's assume that scheduled downtime is not included and let's do some math!

How much money do you spend each year on the 20 percents? on building and maintaining High Availability, redundant and resilient systems to maintain your uptime and comply with your SLAs?

Now multiply this dollar amount by 5 and you get (in an uptime driven World and purely mathematical approach) what you should spend on improving change and release management.
