Case Study: Global System Integrator Company achieves 8–10% developer productivity gain and faster newcomer ramp-up with CAST Imaging (CAST)

Large IT shop speeds up App Dev, boosts developers’ productivity with CAST Imaging

A European-headquartered Global System Integrator providing Application Development & Maintenance for a public transportation client built a near‑shore delivery center and faced three main challenges: accelerating knowledge transfer for newcomers, quickly assessing and minimizing the impact of code changes, and speeding onboarding for new projects across large, heterogeneous applications (Java/J2EE, Angular, COBOL, APIs, Oracle) where existing documentation was inconsistent and teams relied on senior developers.

The integrator deployed CAST Imaging to two teams (30 and 40 developers), with half of each team using the tool daily, and measured results over nine months via their timesheet system. CAST Imaging users showed a steady 8–10% productivity improvement, faster change planning, more precise non‑regression testing and simpler statements of work, and newcomers using the tool reached near full efficiency in about 2 months versus the previous 3–4 months—reducing dependency on senior staff and obsolete documentation.
