• Companies embarking on software development are unwittingly signing up to the biggest lottery in town. Of the estimated £12Billion spent on development during 2007:• £3.5Billion was a total waste• 1st time success stories that delivered the right
features & functions were less than 20%• Projects delivered on time and on budget were less
than 10%
• How can we mitigate waste?• Agile Software Delivery• Agile Infrastructure

Software Plus Services 101
• Enterprises today primarily use software that they run themselves• Commonly known as on-premise software
• Software as a service (SaaS) is becoming a more important part of enterprise IT• Enterprises are moving toward a mixed world of
software plus services (S plus S)
• S plus S = On-premise software + Software as a Service
• Reticence from:• Public Sector• Financial Services Sector
• Blockers:• Data Security• Service Levels• Control
• But:• Better to be secure in the cloud than to send a DVD of
personal data in a jiffy bag via internal mail?• Can you scale your applications right from day one?• Wouldn’t you rather make it Someone Else’s Problem?
S + S: Disruptive IT?
Gartner on SaaS
“Right now [Saas] is a very small part of the marketplace. It only takes up...one-half of one-percent of overall enterprise applications. If you look out eight or ten years, that might go up all the way to 30%”
– Gartner, June 2006
Gartner on SaaS
“There is now a widespread consensus [...] that SaaS is an important and meaningful issue which can no longer be regarded as the ‘lunatic fringe.’”
– Gartner, March 2007
