The document discusses an upgrade of Principal Financial Group's Pivotal CRM system from version 5.9 to 6.0.8. It involved over 23,000 hours of work over 10 months and included challenges like maintaining functionality for ongoing business needs, tight timelines, and extensive customizations over 13+ years. Innovations that helped overcome risks included automating regression testing, operating a 24-hour project team with global resources, shifting schedules, and prioritizing testing based on business and technical risk. Third parties provided over 25% of the hours to help complete the complex upgrade successfully ahead of a key year-end deadline.
