How Diartis Solution creates more room for professional work TEILHABEnet simplifies day-to-day work and prepares reha e.V. for the future.
A change was needed due to new legal requirements, the phasing-out of a legacy system and the high demands of daily case work. In collaboration with Diartis Solutions, reha e.v. has found a future-proof software solution. Complex processes have been simplified thanks to an intuitive, user-friendly interface and tailored adaptation to reha’s specific needs, giving it more capacity to focus on its core activities.

Initial situation and challenges
For a long time, the reha e.v. association relied on a system that functioned, but was increasingly unable to meet the demands of clinical practice. The previous software was originally developed for a different specialist field and only later adapted to meet the requirements of integration assistance.
There was also a fundamental technical change: participation planning processes were significantly revised following the implementation of the UN Convention on the Rights of Persons with Disabilities and Germany’s Federal Participation Act. The old system was no longer able to meet these new requirements. The final impetus for changing the software was the discontinuation of support for the existing solution at the end of 2025. It was clear to reha that a sustainable alternative was needed.
The association conducted a thorough selection process, testing eight or nine different systems. This was important, given that more than 300 employees would be using it every day. Their first impression of TEILHABEnet was unexpected.
Instead of providing an overview of the software on its website, as other providers do, Diartis Solutions required prospective customers to arrange an appointment for a demo.
The presentation was individually prepared and tailored to the association’s processes rather than following a standard sales pitch.
Before the demo appointment, reha described three specific use cases, including the processes involved and the resulting expectations for the software.
The focus was on the following areas:
- Registration with support planning
- Information flow / communication / documentation
- Invoicing
Diartis Solutions then configured and adapted the demo software so that the use cases could be simulated live. They didn’t show mock-ups, but a working environment.
The solution
A project of this size rarely runs without a hitch – there were challenges for reha e.v. along the way that required patience and perseverance: technical terms within the software solution had to be clearly defined, processes coordinated and different professional perspectives – from the social sector and IT – reconciled with one another. These difficulties were successfully overcome through regular, ongoing communication and a professional, dedicated core team.
The agreed deadlines were met, and even a change in project management at Diartis Solutions shortly after the go-live went remarkably smoothly.
« In the long term, TEILHABEnet is better value for money than other solutions. »
Sören Schönfeld Kostulski, Head of Project Development at reha e.v.
« During the training sessions, we often received feedback such as: ‘Oh, wow, that’s great!’ and ‘That’s possible now!’. All our requests were actually implemented, and the improvements were noticed and appreciated by users. »
Anne Wessel, Quality Management and Controlling at reha e.v.
Features and benefits
The new solution has met with a very positive response from employees.
The following aspects have improved significantly:
-
Clear navigation: the software has a flat structure so that content can be found quickly and intuitively without multiple sub-level
-
Comprehensive case management: individual customer files enable comprehensive case management, while an overview across multiple locations provides a higher-level overview of the documentation for several clients.
-
Intuitive use: the user interface is based on familiar Internet applications, making it intuitive for almost all users.
-
High system stability: the system operates stably and reliably, without failures or crashes.
