Rigid coupling
Data logic, process logic, and presentation are tightly connected, making targeted changes unnecessarily expensive.
Case Study: Legacy system modernization
Step-by-step modernization.
We show how a sales process in Apache OFBiz can be modernized step by step with a new backend, a new mobile interface, and without rebuilding the entire legacy system.
Old and new side by side
OFBiz complexity
A modernized part of a legacy system
Apache OFBiz is indispensable in operation, but difficult to evolve in everyday work. Its domain depth is high, while tight coupling, outdated UI technology, and monolithic structures slow down change.
Slow evolution
Even small adjustments trigger regression testing and release processes across the whole system.
High barrier to modern usage
The standard interface is functional, but not built for today’s expectations around usability, mobility, and clear workflows.
The first modernization step
Instead of rebuilding the legacy system, one clearly bounded part is modernized selectively: the sales workflow around leads and customer inquiries.
Step by step, this creates a modern system that is productive and relieves pressure on the legacy platform.

Our approach
Modernize step by step instead of rebuilding from scratch
1. Select the business-critical area
We identify the part of your legacy system that currently offers the biggest leverage and makes sense as a first step.
2. Modernize selectively
We modernize exactly that part so it becomes productive quickly, relieves the overall system, and creates a clean base for the next steps.
3. Continue step by step
After each step, you decide what makes sense next based on visible progress and solid technical clarity.
Traceable down to the code
The modernization is not only visible in the video, but also verifiable technically.
