Maintenance & Modernization
No Manual, No Problem – We Read the Code Directly.
When operating a complex application, the customer faced a critical bottleneck: loss of know-how, missing documentation, and – due to an unexpected death – the loss of their operations partner. We gradually took over maintenance, operations, and further development – including building deep knowledge of the system core. This ensures the application remains future-proof, scalable, and reliable.

Challenge
To secure operations and enable future enhancements, the customer sought external support. The technical hurdle was high: little documentation, many dependencies, and an outdated architecture. The necessary knowledge had to be extracted directly from the source code – step by step, in great detail. Only then could the application be kept stable and further developed long-term.

Success
After an initial analysis, it was clear: we could take over – and we did. Step by step, the required know-how was built up, directly through new requirements and modules. For the customer, this means: the application remains stable and is also ready for future enhancements.
The big advantage: the customer once again has a reliable partner who secures operations, preserves knowledge, and ensures everything keeps running in the background.
Since it’s an older piece of software, we also keep an eye on the «end of life» topic. The customer receives ongoing advice, can better assess risks, and respond early – instead of improvising later.
Approach
We started by taking a close look at the application – including the risks the customer wanted to mitigate. Only once it was clear that we could truly handle maintenance and development, did we begin.
The initial project focused on knowledge transfer. We worked our way deep into the system – enough not only to understand how it works, but also to reliably continue its development.
New modules and enhancements were then implemented step by step – transparently and with a clear cost-benefit evaluation for the customer.
Today, the entire system runs under a maintenance contract: we handle operations, monitoring, and upkeep – so the customer’s technology runs smoothly, and they can focus fully on their core business.
