This document summarizes a presentation given by Em Campbell-Pretty at TDWI Melbourne Chapter in October 2013 about implementing an agile approach to data warehousing at Telstra. The key results of adopting agile methods included reducing delivery cycle times from 12 months to 3 months, increasing delivery frequency to fortnightly, decreasing costs by 50%, and achieving on-time and on-budget deliveries with high customer satisfaction and team morale. Campbell-Pretty outlined how Telstra structured their teams, implemented Scrum practices, and embraced lean principles like respect for people, continuous process flow, and continuous improvement to successfully transition their large enterprise data warehouse to an agile model.
