Company Background▪ PulteGroup has been providing homeownership to families for 60 years. What
started as a single home built and sold by the entrepreneurial spirit of an 18-year-old Bill Pulte, has grown into the industry’s sole multi-brand homebuilding company with the ability to serve customers in all phases of life.
▪ Today, PulteGroup operates in approximately 50 markets throughout the country.
▪ In 2013, PulteGroup closed 17,766 homes earning 5.4 billion dollars in revenue
Problem Statement▪ The company had not kept up with IT system maintenance since 2008,
which prevented the introduction of new technology and compromised the ability to support production systems. ▪ The core financial system and core business functions were running Lawson 8.1
and Oracle 11gR1
▪ Improvements to business functions were limited, at best
▪ Stability was in decline
▪ Performance was major issue
▪ Business continuity plans were manually executed and involved skilled engineers
▪ Cost of extended support was continuously rising
The Goal▪ To create a stable, supportable, and sustainable platform for
future initiatives to be built upon.▪ Maintain a cost-effective computing environment while delivering
improved performance, allowing business processes to be more efficient
▪ Establish a computing environment upon which can be built upon and scaled in the future
▪ Minimize the cost and disruption to the business while achieving the above

The Cost Analysis▪ IBM p770 to Exadata X3
▪ The avoidance of cost for purchasing additional hardware for p770
▪ Purchase of additional Oracle licensing to cover the performance gaps
▪ Purchase of additional Oracle licensing to cover the planned upgrade environment for Infor Lawson
▪ The avoidance of cost for purchasing additional storage capacity on EMC VMAX
$1.7 MILLION IN CAPITAL SAVINGS

▪ Operational expense savings of approximately 4 months of DBA time
▪ On time delivery into production
▪ Nearly 2X performance gains
▪ Exadata platform has brought stability to the environment, curing performance issues
▪ Patching “many-as-one” brought ease to meeting the supportability goal
▪ The unexpected unused capacity has given opportunities to bring in additional workloads without capital expenditures
