A global System Integrator (SI) is providing Application Development and Maintenance (ADM) services to thousands of clients. In this case, its client is a European public transportation company.
CAST Imaging enabled faster delivery of change requests and accelerated newcomer onboarding. The SI measured the impact on two teams where only half of each team was using CAST Imaging daily.

CAST automatically showed me links and components used by the application that were unknown to us before and we were able to overhaul this part of the application much faster

The Global SI had been serving for 15 years its client, a major public transportation company in Europe.
As the business needs grew, the client and the SI were looking at scaling by building a new near-shore delivery center, as well as finding a way to boost the speed of delivery and onboarding of newcomers.
There were several hard-to-address challenges:
Half of each team was using CAST Imaging daily and the other half was not using CAST Imaging at all.
Based on their well-established internal time-tracking process, the SI observed over a period of 9 months the average time for implementing typical change requests.
The Global SI compared the efficiency prior to the teams using CAST Imaging and the difference of productivity for developers who use CAST Imaging vs. those who do not.
Before the introducing of CAST Imaging, the productivity of all developers was largely the same.
After introducing CAST Imaging, the SI measured a steady productivity gain of 8-12% for those using CAST Imaging (fig 1).
Teams using CAST Imaging could build change plans faster, they could define the non-regression testing more precisely, and they could create their statement of work more easily.
The Global SI also looked at the ramp-up time for newcomers (fig 2).
Given the long experience with their client and its applications, the Global SI already knew that a newcomer or internal transfer needs 3 to 4 months to be fully productive, meaning, to be fully efficient working on changes and on maintenance tasks.
The Global SI observed that now newcomers could be almost fully efficient after 2 months vs. to 3 to 4 months prior to use CAST Imaging.
