Case Study: Allianz Austria achieves a 230% increase in application functionality and 20% cost reduction with CAST

230% Increase In Application Functionality With A 20% Annual Cost Reduction Over 3 Years

Allianz Austria runs a 2.5M-line insurance management system supporting 10 million customers and 8 million claims per year across multiple platforms. Rapid change—30 developers handling 300 RFCs/year and 700,000 lines modified annually—doubled the code base (2001–2003) and pushed bug-fix effort from 15% to 30%, prompting a company-wide quality management initiative.

Allianz implemented CAST (with short vendor consulting and 60 days to define processes and reports), integrating it with internal project and configuration management to deliver automated, whole-application analysis and enforce company-specific quality rules. Weekly analyses, objective “Quality Certificates,” and metrics-driven appraisals enabled teams to focus fixes, yielding a 73% average achievement of quality goals, analysis of 40 projects in 2003, substantial reduction in bug-fix effort, a 230% increase in application functionality and a 20% annual cost reduction over three years.
